Product review: Rugged tablet tackles survey tasks
Photo: DT Research

Technology continues to develop and put more capability, data storage and ease of use into many professional’s hands, and surveyors are no different in their needs.

Spatial data collection has become an important task in the diverse service world of today’s surveyor with a variety of platforms, sensors and techniques being used to provide this operation.

The movement toward completing a “digital twin” of existing improvements and facilities worldwide has opened the door for new means and methods for data collection. Surveyors are taking a front-line role in producing the spatial data necessary for much of the internal and external infrastructure being used in today’s cutting-edge digital modeling.

Necessary accuracy and precision

However, not all data-collection systems offer the accuracy and precision deemed necessary by today’s surveying profession. These systems also need to be tough enough to handle the environmental conditions surveyors face in their everyday work, yet be user-friendly enough to make the data-collection process efficient.

Surveyors require a system designed for rugged use, yet built with a high-visibility screen, easy-to-use interface and reasonable battery life to allow effective and confident data collection. Many data collectors tout these features, but many of them fail when subjected to the harsh conditions of surveying and construction sites.

Times, however, are a changing and a new tablet is raising eyebrows.

DT Research Inc., a Silicon Valley electronics provider, has provided mobile and medical computing devices to many professions for more than 20 years. They have taken one of their most popular models, the DT301, and added integrated significant upgrades that brings it squarely into the surveying and geospatial world.

This rugged tablet can now include a multi-frequency GNSS module and a second, 3D-capable, stereo-imaging camera for capturing photometric information.

Specifications

Here are the overall specifications for the DT301X-TR Rugged Tablet:
- Intel 8th-generation core i5/i7 processor
- Microsoft Windows 10 IoT Enterprise operating system
- 10.1-inch sunlight readable capacitive touch screen
- High-capacity, hot-swappable battery pack with power-saving modes
- IP65-rated for water and dust resistance
- MIL-STD-810G for shock and vibration protection
- MIL-STD-461F for EMI and EMC tolerance
- Multi-frequency GNSS (including GPS, GLONASS, Galileo and BeiDou)
- External GNSS antenna capable
- Intel RealSense Depth camera, 2D barcode scanner
- Long-range Bluetooth, 4G LTE, digital pen support
- Sturdy external keyboard with various mounts for static installation
- Rugged yet reasonable weight of 3.1 pounds
- Multiple mounting options for precise measurement
Rugged, but not too heavy

The first impression a new user of the DT301X-TR will notice is that while it is heavier than the normal personal tablet, it is very rugged yet not noticeably heavy. The additional weight it does carry, however, gives the user a sense of durability and confidence to take it into fouler environments without fear of infiltration or hazardous climate concerns.

The external bumpers can take significant abuse, and the rubber rear guard is used for gripping the tablet effectively during data collection tasks. Several mounts are available for this unit, including a pole mount in conjunction with the external GNSS antenna for higher accuracy location determination.

This unit runs the Microsoft Windows 10 IoT (internet of things) Enterprise operating system, so most users will already have a general feel for the overall interface. All the normal Windows tools are there (email, browser, etc.), so little training is needed for beginners.

Connectivity is available through dual-band Wi-Fi and/or 4G LTE communications as well as long-range Bluetooth connections where needed. The unit runs on an Intel 8th-generation core processor and SSD storage for fast computing and data access needs.

In addition to computing performance, this model also exceeds expectations with its robust screen. Where most high-def screens on phones and tablets suffer in daylight conditions, the DT301X-TR allows the user to maintain great visibility and keep working with visual confidence.

GNSS module and antenna

The DT301X-TR can be loaded with several data-collection software packages, depending on your application. For traditional surveying, Microsurvey’s Field Genius is used for locating survey points with the GNSS module. Several programs for data collection are available, depending on the accuracy required by the user.

A helical mobile dual-frequency GNSS antenna is mounted directly on the tablet for receiving survey-grade positions with an RTK correction service. The tablet can also be used with an external GNSS antenna mounted on an extendable pole for a more conventional surveyor-style method of data collection while providing stability for the user.

The data-collection process for mapping is intuitive and allows for uploading existing shapefiles for reference to existing conditions. Exporting information after the data-collection task can be completed in two different formats: shapefiles and KML files.

For the higher accuracies typically required for surveyors, the unit utilizes the pole mount to ensure the accuracy level is not compromised by human interaction, and it connects to an external GNSS antenna. The software allows the user to collect more precise locations through several means: static, real-time kinematic from the user’s base station, or through a real-time network solution from an external source.

The data collection process in Field Genius is very user friendly and allows for customized point naming and automatic linework between points. Field Genius also contains standard COGO tools and routines that allow the user to perform field calculations right on the job, saving valuable time and money for the practitioner and the client.

Exporting of field data is robust and allows for creation of DXF/DWG files of linework and LandXML files for surface and point downloads. The user can also export raw data in a GNSS Survey format or the industry standard “field book” format as well. Importing background files is just as simple, so the user can have additional information at their fingertips for reference during their data collection process.

Also, the DT301X-TR can be utilized for construction staking with an extensive array of staking reports available for user verification. Proposed TIN surface models can be imported for site and roadway staking for placing cut/fill points on the fly.

Cameras make it shine

The DT301X-TR, however, is not just a fancy conventional surveying data collector; the Intel RealSense Depth camera and DOT3D Pro software from DOT Product is the latest development to be added to the rugged tablet that makes this platform shine. This latest technology from Intel allows the user to photograph and video spaces that even the newest laser and lidar scanning equipment can’t access.

Stereo depth modeling is enhancing the data-collection process for surveyors as a new tool to collect important information for engineers, architects and contractors. By collecting close quarters information in real time, a more complete BIM and/or “digital twin” data set can be accomplished faster and more cost efficiently than ever.

This version of remote sensing is becoming very popular with other vehicles and platforms (such as UAVs), yet being integrated into a single unit with GNSS capability is key to making the DT301X-TR a game changer.

The divide between the macro (GIS mapping) and micro (traditional surveying) of spatial data collection is closing, but it will take some time before satisfying the surveying community. The DT301X-TR is closing that gap by marrying the accuracy of GNSS measurement with the precision of 3D analyzation technology.

DT Research began by creating a bulletproof tablet made for durability and dependability, but has raised the bar with a state-of-the-art satellite measurement module and remote-sensing capability through the RealSense camera system.

Wrapping all this technology into a rugged unit running on an industry-standard software platform, DT Research has provided an insight to what the future of data collection looks like, no matter what profession one is in.

The DT301X-TR provides multi-frequency GNSS real-time kinematic (RTK) with carrier phase for mapping and positioning, and supports GPS, GLONASS, BeiDou, Galileo and QZSS.

The optional foldable antenna supports high-accurate measuring field work, which can be measured with RTK GNSS positioning directly, or used to connect to an external antenna for higher precision.

Its 10.1-inch high-brightness capacitive touch screen can be read in a wide range of lighting indoors and outdoors. The tablet comes with a choice of Intel 8th-generation Core i5 or i7 processors. Its MIL spec and IP ratings means it holds up to real-world hazards and performs in many industries and environments.

Integrated 3D camera. The DT301X-TR integrates the optional Intel RealSense Depth camera which provides real-time 3D imaging to quickly and accurately create measurements for CAD, engineering, design, utility and project management, and crime/crash scene forensics. Scientific grade data, which is important for evidence as well as building plans, is now easier to access and use for specialists and non-credentialed workers alike.

With this 3D camera technology, depth perception is integrated to add the most accurate image to make projects stay factual and consistent. The integration of the 3D camera with a rugged handheld tablet improves the mobility and reduces the bulk and limitations of a laser scanner for small, hard-to-reach spaces and brings the measurement, real- time scanning, and positioning together in one device which can also be used to process and transmit the data.

Using rugged tablets with 3D technology allows the as-built status of a project to be tracked and documented in real time, reducing the project cycle time, and also allows data to be shared with the owner, general contractor and subs as it is captured. This boost to efficiency and accuracy validation shortens payment cycles as well as improving the overall BIM (building information modeling), getting infrastructure going quickly and getting payments to contractors faster.

“The combination of the DT Research rugged tablet with the RealSense depth camera and DotProduct’s Dot3D Pro software enables projects to be quickly set up, tracked, and completed for all staff and tasks whether in the office or on the site. The ease of use these tools bring to 3D workflows can benefit a wide range of applications from construction verification to asset management to crime scene mapping.” says Tom Greaves, chief marketing officer at DotProduct.

Data capture options besides the 3D camera are a 2D barcode scanner for equipment/location tags, long-range Bluetooth for 1,000-foot range suitable for connecting to robotic total stations and 4G LTE mobile broadband for the latest in high speed communications.

The flexibility for set up and use is enhanced in the DT301X-TR rugged tablet with Microsoft Windows 10 IoT Enterprise operating systems for convenient integration with existing applications, bringing together the advanced workflow for data capture, accurate positioning and data transmitting.

Another option is a bright LED light that can be attached to the DT301X-TR and stay consistently on for up to two hours, bringing light to underground infrastructure mapping and scanning.

With high capacity 60 or 90 watt hot-swappable batteries, the rugged yet lightweight DT301X-TR keeps working continuously whether in the field, office, or vehicles, complemented with a variety of battery chargers so fully charged batteries are always available.

This rugged tablet gives detailed accuracy combined with the latest 3D camera technology all in one tablet that is rugged and easy to use in the field. Whether at the construction site, mapping underground utilities, or at the freeway crash scene, the cost-effective DT301X-TR is ideal for accurate measurements to enable data-driven decisions, able to travel to wherever the work is.

The DT301X-TR rugged tablet will be available in May 2019 from DT Research’s authorized resellers and partners. DT Research will be at booth 217 at AEC’s BuildTech show.

The Oregon Department of Transportation (ODOT) has expanded its use of DT Research GNSS rugged tablets to all 15 of its construction management offices across the state, and also use the tablets for biology, geology, roadway and wetland projects.

DT Research worked closely with ODOT to design purpose-built rugged tablets that empower state workers to easily collect and transmit geospatial measurements in the field using GNSS real-time kinematic (RTK) technologies.

“DT Research’s GNSS rugged tablets have enabled us to bring high-accuracy geospatial measurements to workers across the Department of Transportation, which has literally changed the way we work,” said Chris Pucci, construction automation surveyor at ODOT. “The tablets have enabled us to save time, reduce costs and improve the accuracy of projects through ‘digital-as constructed’ measurements and real time data capture.”

The tablets have a dual-frequency GNSS module built in, which provides stand-alone sub-meter accuracy to centimeter-level accuracy with RTK from GPS, GLONASS and Galileo satellites.

The tablets are compatible with existing survey and GIS software for mapping applications and provide an advanced workflow for data capture, accurate positioning and data transmitting.

“We now have essentially created one-person survey crews because the DT Research tablets are so much easier to use than a tape measure and paper to accurately calculate and record measurements during complex construction projects,” Pucci said. “Using the tablets saves us an average of $2,000 for every survey-grade measurement job that does not require a full survey crew.”

“In addition, the tablets have provided us with a contract verification system by having highly accurate digital-as-constructed measurements that are delivered immediately and stored forever, which saves the state time and money by avoiding independent re-measurement checks due to billing discrepancies at the end of a project,” added Pucci.

The DT Research GNSS tablets can store up to 1 Terabyte of data for field data collecting. Users can avoid down time with a high-capacity hot-swappable battery pack, which delivers 60 or 90 watts for up to 15 hours of continuous mobile communications. The units include Long Range Class 1 Bluetooth, which powers wireless connectivity up to 1,000 feet and 4G mobile broadband.

“The simplicity of how the DT Research tablets work is amazing,” Pucci said. “Unlike complex professional survey equipment, the DT Research tablets are a Windows-based mobile device with a user interface that is familiar to workers. In just two hours, I can easily train state workers with diverse skill sets to measure quantity, linear features and volumes for a variety of projects — and they are ready to go.”

The tablets run on Microsoft Windows 7 Professional or Windows 10 IoT Enterprise and are high performance devices with an Intel 6th or 8th Generation Core i5 or i7 processor. The rugged tablet is designed for outdoor use with a brilliant LED-backlight, 800 nits sunlight-readable screen and capacitive touch.

“We have found the DT Research tablets to be incredibility easy to manage and highly durable — we just turn them on and they work,” said Pucci. “In the three years that we have used the tablets, we have had very few technical support questions and they hold up well in different weather conditions. There isn’t a comparable product on the market at the price point.”

The DT Research tablets are military-grade durable devices, yet lightweight, offering the versatility to be used in field-to-office settings. For use in harsh environments, the tablet is fully ruggedized to meet the highest durability standards with an IP65 rating, MIL-STD-810G for vibration and shock resistance and MIL-STD-461F for EMI and EMC tolerance.

For use in a variety of environments, the tablets are complemented by many accessories including: external antennas, pole mount cradles, detachable keyboards, battery charging kits and digital pens.

Photo: DT Research

DT Research has launched the DT372AP-TR rugged real-time kinematic (RTK) tablet, a lightweight military-grade tablet that offers RTK to enhance the precision of position data derived from satellite-based positioning systems.

The tablet enables 3D point cloud creation with centimeter-level accuracy to meet the high standards required for scientific-grade evidence in court, the company said.

The DT372AP-TR RTK tablet is military-grade with an IP65 rating, yet lightweight — offering the versatility to be used in the field, office and vehicles.

A dual-frequency GNSS module is built into the tablet, which uses real-time reference points within 1- to 2-centimeter accuracy to position 3D point clouds created from aerial photogrammetry, using GPS, GLONASS and Galileo satellites. Users can measure with the RTK GNSS positioning directly using an external antenna for better survey-grade precision.

“We designed a more compact tablet that still offers all the functionality of a rugged RTK tablet, to give ultra-mobility to law enforcement and first responders who are already weighed down with heavy equipment,” said Daw Tsai Sc.D., president of DT Research. “With programmable side buttons and directional pad, this tablet combines ease of use with a small form factor and centimeter level accuracy, there is nothing in the market now in the same category that can offer this combination.”

The DT372AP-TR RTK tablet is compatible with existing survey and GIS software for mapping applications and brings together an advanced workflow for data capture, accurate positioning and data transmitting.

The tablet can be used in a variety of scenarios, including:

Forensic mapping. Public safety teams, investigators and crash reconstructionists can use the DT372AP-TR to accurately collect measurements that are scientifically and legally defensible by using the real-time centimeter reference points to position 3D point clouds created from aerial photogrammetry or take stand-alone measurements. By using the tablet with a drone for crime and crash scene investigation, cost goes down while accuracy and speed improve, helping to clear areas faster, thereby improving overall public safety.

Land surveying. Surveyors can use the DT372AP-TR RTK tablet to measure the altitudes, angles and distances on the land surface so that they can be accurately plotted on a map to determine property boundaries, construction layout and mapmaking.

E-construction. Construction workers can manage the collection, review, approval and distribution of highway construction contract documents in a paperless environment using the DT372AP-TR RTK tablet.

The tablet has been purpose-built for precision mapping in a variety of environments and includes the following features and capabilities:

DT Research’s new military-grade tablet has RTK GNSS
DT Research has released the DT301T rugged RTK tablet (DT301T-RTK), a lightweight military-grade tablet purpose-built for GIS mapping applications. It features real-time kinematic (RTK) satellite navigation to enhance the precision of GNSS position data.

The tablet enables 3D point cloud creation with centimeter-level accuracy, meeting the high standards required for scientific-grade evidence in court.

The DT301T Rugged RTK tablet is military-grade with an IP65 rating. Because it’s lightweight, the DT301T can be used in the field, office and vehicles, the company said.

A dual-frequency GNSS module is built into the tablet, which uses real-time reference points within 1–2-centimeter accuracy to position 3D point clouds created from aerial photogrammetry, using GPS, GLONASS and Galileo receivers. Users can measure with the RTK GNSS positioning directly using a foldable antenna or connect to an external antenna for more robust receiving and survey-grade precision.

“We’ve seen a dramatic uptick in the need for rugged tablets to be purpose-built for a range of mapping uses across industries,” said Daw Tsai Sc.D., president of DT Research. “In designing the DT301T with RTK satellite navigation, we also took into consideration the other features and capabilities necessary within a rugged tablet to quickly and easily conduct forensic mapping, land surveying, e-construction, building information modeling (BIM) and other mapping scenarios.”

The DT301T is compatible with existing GIS software for mapping applications and brings together the advanced workflow for GIS data capture, accurate positioning and data transmitting.

Uses

According to DT Research, the tablet can be used in a variety of scenarios.

Forensic mapping. Public safety teams, investigators and crash reconstructionists can use the DT301T Rugged RTK tablet to accurately collect measurements that are scientifically defensible by using the real-time centimeter reference points to position 3D point clouds created from aerial photogrammetry or take stand-alone measurements.

The results will have the precision necessary to stand up as evidence in court, said Andrew S. Klane, a former Massachusetts State Police Lieutenant who teaches Forensic Mapping and is now the chief operating officer at Forensic Mapping Solutions Inc.

“As more drones are being used for mapping, there is a growing need for ground-control positioning devices,” Klane said. “By using a DT301T Rugged RTK Tablet in combination with a drone, users can more quickly and cost-effectively create a 3D model to deliver an accurate representation of the scene with scientific-grade tolerance that will hold up in a court of law.”

It could also help clear crash scenes faster, restoring the normal flow of traffic on congested roadways, reducing secondary crashes and lowering the chance of first responders and other workers getting hurt while clearing the scene.

Land surveying. Surveyors can use the DT301T tablet to measure the altitudes, angles and distances on the land surface so that they can be accurately plotted on a map to determine property boundaries, construction layout and mapmaking.

E-construction. Construction workers can manage the collection, review, approval and distribution of highway construction contract documents in a paperless environment using the DT301 tablet.

Building information modeling (BIM). Architecture, engineering, and construction (AEC) professionals can use the tablet to create 3D models to efficiently plan, design, construct and manage buildings and infrastructure.

Oregon moves to tablets for no-stake 3D

The Oregon Department of Transportation (ODOT) is embracing the growing trend in highway construction to go “stakeless” and push to full 3D design.

With more contractors using automated machine guidance applications, ODOT’s construction personnel are being asked to inspect projects with fewer stakes and visual indicators for line and grade. Employees are seeking to use the same data and information to determine line and grade when building or fixing stretches of road.

To address this need, rugged tablet maker DT Research worked closely with ODOT to design purpose-built Inspector Positioning Tablets that run GPS locating and 3D modeling applications, and take advantage of the Oregon Real-Time GNSS Network.

“MicroSurvey Field Genius surveying software is used to read XML files directly, allowing the inspector to work with the same files that the contractors received from the roadway designers,” said Chris Pucci, ODOT Construction Automation Surveyor.

The tablets enable ODOT to fully use its knowledge of the Oregon Real-Time GNSS Network and expertise in survey-grade RTK GNSS to achieve accuracies of +/0.05 feet.

The model DT391GS tablets have 9-inch touchscreens. The tablets can be used as handhelds or with an external antenna and pole. ODOT purchased one of four GNSS options offered by DT Research for the DT391GS tablets. The options enable inspectors and construction crews to employ a combination of GPS locating and 3D modeling to guide construction workers.

The goal is to allow the inspectors to make the same checks they would have made if there had been traditional construction staking on a project, not to make inspectors into surveyors, Pucci noted.

A one-day training is provided to train construction personnel before they are issued a tablet. “The tablets have been very well received by our construction inspection personnel,” he said.

The tablet project is now in the pilot phase with 20 tablets deployed to eight construction offices and more than 70 construction personnel having been trained. “We also just placed an order for 22 more tablets for the upcoming 2017 construction season,” Pucci said.

New DT Research tablets aimed at field professionals
DT Research has released the DT395CR and DT395GS rugged tablets. While designed for field professionals, the tablets cost less than consumer-grade tablets over the lifetime of the product, DT Research said.

The DT395GS rugged tablet by DT Research.

Both DT395 tablets are highly durable to withstand extreme environments, designed with fully integrated options to eliminate easily broken attachments in mission-critical scenarios, and include security, privacy and productivity settings.

The DT395GS tablet is designed for field applications with a high-accuracy GNSS module that is compatible with existing GIS software for mapping applications and brings together the advanced workflow for GIS data capture, accurate positioning and data transmission. The u-blox M8 GNSS module is capable of concurrent reception of GPS and GLONASS for up to 2-meter accuracy.

“Many businesses have adopted mobile tablets with the goal of increasing productivity by leveraging the versatile tablet form-factor,” said Daw Tsai, president of DT Research. “But companies within construction, field service, logistics, manufacturing and warehousing have found that consumer-grade tablets are too fragile for their environment — requiring costly repairs and replacements that introduce expensive downtime. Our new DT395 rugged tablets give vertical industries exactly what they need with high reliability and lower TCO (total cost of ownership) over the lifetime of the product.”

According to a VDC Research study, the average annual TCO of a ruggedized tablet is 22 percent lower than the average annual TCO of a non-rugged tablet. The study found average failure rates for non-rugged tablets is 15.2 percent compared to 6.9 percent for rugged tablets. Lost productivity, as a result of mobile device failure, was a leading contributor to higher TCO for non-rugged tablets. Mobile workers lost an average of 52-80 minutes of productivity when their mobile device failed. (Source: VDC Research, “Total Cost of Ownership Models for Mobile Computing and Wireless Platforms,” Third Edition.)

Unlike consumer-grade tablets, the DT395CR and DT395GS ruggedized tablets are designed to be used in a variety of indoor and outdoor environments with full HD anti-reflection outdoor viewable displays. The tablets are IP65 and MIL-STD-810G rated to withstand 4-foot drops and extreme temperatures (-4° F to 140° F), and resist water, dust and humidity.

“We tried iPads, but they were not suited for our environment,” said Marty Phillips, director of engineering at Murray Equipment, Inc. “Our customers do millions of dollars of fertilizer loading within an eight-week window in a broad range of weather conditions. If a remote control tablet is down for even an hour, it’s a significant revenue loss. We have used DT Research rugged tablets in our automated liquid-handling facilities across the U.S. for more than three years with no downtime or repair/replacement costs. The reliability of DT Research’s rugged tablets is unmatched.”

Both the DT395CR and DT395GS have an 8.9-inch display with 1920 x 1200 resolution and capacitive touch, and weigh 2.87 pounds. The tablets run on an Intel Atom Quad Core CPU with 4GB RAM running Microsoft Windows 10 IoT Enterprise OS.

Security, privacy and productivity settings

“Security, privacy and productivity are a growing concern in many organizations,” Helen Fanucci, GM of Americas Device IoT Experience, Microsoft. “We are pleased to see DT Research utilize the Windows 10 IoT Enterprise-grade security to support mission-critical rugged tablets for customers and deliver a safer device experience, which enhances productivity for a variety of mobile scenarios in manufacturing, field service, logistics and other industries.”

The DT395 tablets leverage advanced Windows 10 IoT Enterprise OS security including Device Guard, combining hardware and software security to lock down a device so that it can only run trusted applications. The DT395 also includes lock-down features to protect against malicious users while providing a custom-defined user experience.

Bluetooth, Wi-Fi, and RFID can pose a security issue when using consumer-grade tablets within a business environment. DT Research DT395 rugged tablets can be purpose-built with a camera privacy mode and

preconfigured with Bluetooth, RFID and Wi-Fi disable functions. The DT395 rugged tablets can also eliminate access to internet or social media applications to address productivity challenges.
