    Flight management

    For pilots to use GPS as primary means of navigation

    The GPS-4000S sensor provides GPS-based navigation and enables GPS-based approaches for aircraft equipped with flight management systems. The sensor’s Space-Based Augmentation System (SBAS) capabilities enable use of GPS as the primary means of navigation in areas of SBAS coverage. The GPS-4000S uses up to 10 GPS satellites and two geostationary SBAS satellites. However, users can calculate navigation with a minimum of four GPS satellites with acceptable geometry or three satellites plus calibrated barometric altitude. With additional satellites, the system’s Receiver Autonomous Integrity Monitoring (RAIM) detects and isolates defective satellites while improving navigation accuracy. Predictive RAIM capability determines if the future satellite geometry at the destination airport will support planned arrival procedures.

    Large-area lidar

    For advanced mapping, law enforcement

    The Phoenix Ranger RL1-UAV produces photorealistic 3D point-cloud data collected efficiently over extensive regions. For law enforcement, the data can provide greater context, awareness and tactical accuracy. Agencies typically use ground-based lidar as a forensic crime-scene mapping technology. Aerial lidar is efficient for larger, outdoor scenes because line-of-sight issues can restrict ground lidar scans from capturing the entire area. Benefits for law enforcement include exposing unmapped trails hidden in remote backwoods; determining width, elevation and length of roads; detecting micro topography hidden by vegetation; and gathering ground-surface information affected by human activities. The Phoenix Ranger RL1-UAV provides survey-grade (cm-level) accuracy with 920-meter laser range and outstanding intensity calibration. Options include IMU and dual-GPS upgrade for increased accuracy.

  • Accuracy, precision and boundary retracement in surveying

    Accuracy, precision and boundary retracement in surveying

    Technology has improved the scientific community’s ability to measure in many ways that our ancestors would have trouble believing. From obtaining measurements across galaxies down to the tiniest of atom splitting, our ability to measure is exceedingly robust. The land surveying profession has benefitted from this ongoing technological revolution in many ways (GPS World March 2017) and has advanced our work in many new directions never thought possible. Substantial increases in precision through these advancements allows the land surveyor to perform various tasks, including topographic surveys, construction layout and volumetric surveys with increased confidence.

    Graphic: https://sites.google.com/a/apaches.k12.in.us/mr-evans-science-website/home

    Accuracy and precision are two factors that go into our measurement procedures. While accuracy and precision are considered to be the same thing by a large portion of the population, it couldn’t be more from the truth. Accuracy is defined on how well a measurement or reading is in relation to a known value or benchmark. Precision, on the other hand, is how closely a measurement is repeated yet has no relation to any given value or benchmark.

    The introduction of GNSS technology along with total stations with locking electronic distance measuring (EDM) mechanisms in the 1980’s brought more precision into the hands of the surveyor. These innovations reduced the amount of human error in our measuring procedures when used in an appropriate manner as well as allowing greater distances to be covered. The implementation of various real-time networks (RTN) on several continents also continues to increase our range of high-precision location and measurements worldwide. However, as we develop our next generation of surveyors through educational programs and apprenticeships, we are making a terrible mistake in replacing many fundamental land surveying principles and legal precedents with more emphasis on precision and less on legal accuracy based upon precedents.

    Surveyors and the role of measurement

    In ancient civilization, the primary role of the land surveyor was to help establish and maintain property boundaries. Measurement devices included knotted rope, the Gunter chain and the compass, all used is varying manners and precisions. Paramount to the surveyor’s effort was the establish of monuments at corner points of the tracts they were measuring. These points were held as the ultimate dividing point and superior to associated measurements and secondary tie points. This simple guide for all surveyors has been a core principle of property owner’s rights and upholding those rights in the name of the law. By placing of monuments, the landowner has relied on the surveyor to physically define the property being established and conveyed.

    Let’s ask Washington, Jefferson and Lincoln…

    For example, in early days of the United States during the late 1700’s/early 1800’s, once an original survey was completed, notes of each survey were preserved by various means. Most governmental surveys of the early 1800’s were transcribed onto large township sheets in order to perpetuate and preserve the work performed by the Land Office surveyors. The establishment of states and local governments brought forward land and records offices in which these government patent lands were further subdivided for conveyance to settlers of the new lands. In each of these cases, corners of various types were set to distinguish boundaries between property ownership. Wooden posts, rock mounds, and other materials were used to physically mark the locations of the corners, with notes, documentation and deeds for conveyance coming after the determination of the property. Regardless of any variation from the notes/plats/deed descriptions, property rights were held to the physical locations of the markers set during the course of the survey.

    The American dream of land ownership

    As more people moved westward and parcel subdivisions became more prevalent, planned developments began to be based upon pre-calculated figures. Before calculators and computers, the surveyor would determine the location of new parcel corners by hand derived calculations (usually in the field) and use a transit and chain to stake each parcel corner. Notes were carefully kept during the lot creation process and transferred to a final plat for filing at the county recorder’s office. These plats were typically post-survey with the detailed notes being drawn on the plat with specific dimensions to all points set.

    As plane geometry and coordinate systems caught on (GPS World November 2016), the movement toward pre-calculated subdivisions became more common. Couple this method of calculation with increased capability of high precision theodolites and the World War 2 postwar boom, the economy and environment was ready for more time efficient surveys. Now large parent parcels were being subdivided on paper before any additional surveying was performed to establish the new lotting configuration. Surveyors began to stake parcel corners by means other than “running the lines”, i.e. physically occupying the outer boundary and setting internal points for new parcels. Add to this environment of “faster” surveying the invention of the EDM, digital total station, computer programming and analysis along with GNSS, and now we have a recipe for the most precise and accurate surveying ever performed. Or do we?

    These are not your father’s (or grandfather’s) survey methods anymore

    Regarding topographic, volumetric, bathymetric and aerial surveys, I would agree that technology has advanced our profession to greater heights. These tasks have benefited greatly by increased data collection, remote location and sensing and computing power. The surveyor’s ability to provide an extremely detailed set of data for varying surfaces and site conditions is at an all-time high with more technology continually being developed. But how has technology affected our primary role of boundary line expert? While in many ways as technology has helped the boundary survey, it has also taken away from the surveyor’s responsibility and duty as expert measurer. The intent of the surveyor is mostly clear when retracing a prior survey or creating new parcels from existing ones but execution, along with mistakes/errors/blunders, throw ambiguity into the fold. Not knowing where to find a random error within a prior survey leads many practitioners down a long and frustrating path. In a perfect world, the math would all work out and everything fits together like a glove. However, due to many variables and errors that randomly and systematically happen during our work, this condition is near impossible to attain. This quote is from the “Illinois Boundary Law” book written by land surveyor/attorney Jeff Lucas in 2012 sums it up well:

    “There is an irresistible urge on the part of many surveyors to trust math and measurements over their understanding of boundary law principles. When this misplaced trust is coupled with the confusion over the land surveyor’s duties and responsibilities, the land surveyor is free to ignore clear-cut doctrines of law when precision expectations come into conflict with the realities that are found on the ground.”

    So, what does this mean? Many of the legal descriptions surveyors have been charged with to perform a boundary survey were created using equipment, techniques and simple math far inferior to today’s standards. For example, a survey in downtown Chicago may be based upon a plat from the early 1800’s, (if the record happened to survive the Great Fire of 1871) and was depicted in chains and links. We now have surveyor who show all dimensions to the 1/1000th of a foot on these boundary and land title surveys. Considering that most of the surveys from that era only had a precision of one link (0.66 ft.), it could be considered overkill to need to be that precise. I’m in agreement that the survey must depict the current conditions and properly define where boundary rights are physically located, but to show that many significant figures is careless and unnecessary.

    For surveys on larger parcels and in rural areas, GNSS use (and abuse) now comes into play much more often. As I’ve written previously (GPS World May 2016) GNSS implementation is the single greatest advancement of surveying technology in my opinion. The ability to survey significant areas with great precision still impresses me and I wouldn’t trade it for anything. But notice I stated “precision” and not accuracy and this is where many surveyors get off track; hence, the statement from Mr. Lucas.

    You’re not the original; you’re the retracement

    While a small proportion of surveys completed today are for government lands and follow the Bureau of Land Management’s Manual of Surveying Instructions (2009 Edition), the remaining surveys are broken into two categories by whom they are performed by: the original surveyor or the retracement surveyor. This is best described from the text of the well-known Florida court case of Rivers v. Lozeau (539 So.2d 1147 (Fla. App. 5 Dist. 1989):

    “First, the surveyor can, in the first instance, lay out or establish boundary lines with an original division of a tract of land which has theretofore existed as one unit or parcel. In performing this function, he is known as the “original surveyor” and when his survey results in a property description used by the owner to transfer title to property that survey has a certain special authority in that the monuments set by the original surveyor on the ground control over discrepancies within the total parcel description and, more importantly, control over all subsequent surveys attempting to locate the same line.

    Second, a surveyor can be retained to locate on the ground a boundary line which has theretofore been established. When he does this, he “traces the footsteps” of the “original surveyor” and locating existing boundaries. Correctly stated, this is a “retracement” survey, not a resurvey, and in performing this function, the second and each succeeding surveyor is a “following” or “tracing” surveyor and his sole duty, function and power is to locate on the ground the boundaries corners and the boundary line or lines established by the original survey; he cannot establish a new corner or new line terminal point, nor may he correct errors of the original surveyor. He must only track the footsteps of the original surveyor. The following surveyor, rather than being the creator of the boundary line, is only its discoverer and is only that when he correctly locates it.”

    The surveyor’s role in boundaries, period

    To further illustrate the surveyor’s role in each type of survey, let’s examine the recent publication of “Boundary Retracement Processes and Procedures” by Donald A. Wilson, a long-time land surveyor and prolific writer of surveying manuals. Don’s book delves deep into all things concerning the role of the land surveyor in completing a property retracement survey. While surveying does rely heavily on good measurement techniques, it goes along with a handful of other talents as well. Don’s book revisits a 1985 Vermont Society of Land Surveyor’s publication “Cornerpost” (VSLS Cornerpost) that contained an article titled “What does a land surveyor do?” written by George F. Butts. In the article, George lists in detail that besides the prerequisite surveying knowledge, the surveyor must also have some aspect of skills for the following disciplines: archaeologist, astronomer, cartographer, computer specialist, dendrologist, detective, engineer, farmer, forester, geologist, handwriting expert, historian, hydrologist, lawyer, logger, judge, juror, photogrammetrist, writer, and expert witness. Notice that George didn’t include mathematician or statistician, both disciplines that rely heavily on the study of formulas, figures and data. While surveying computations relies heavily on geometry and trigonometry, the first order of business in data analyzation is how it relates back to the “original survey.” This brings us back to the primary role of the land surveyor – “following the footsteps.” As Don quotes; “…following the footsteps of the original surveyor is the legal standard adopted by the courts in all jurisdictions, and for very good reason.” The intent of the retracement surveyor is to uncover the past through all necessary information and bring to life the original survey. How the surveyor gets there, through the muddied use of technology, often leads us down the wrong path. He also adds from the 1818 South Carolina court case of Bradford v. Pitts (2 Mills. Const. Rep 115); “Blind devotion to a rule may lead to infinite failure.”

    Back to the Stone Age?

    So, what is the answer? Do we throw out all the electronic tech and time-saving methods in order to retrace all surveys with compass and/or transit and chain? Of course not. I do ask that all surveyors look at what the profession has charged them with and how they use their tools to get there. For instance, I am thankful for all the medical breakthroughs in the past 100 years, especially when it comes to technology. Imaging machines, robotic laser procedures for internal surgeries and more come to mind, but let’s remember that doctors still look at the human element and not just what a computer spits out as a diagnosis. How many times have you looked up your symptoms on WedMD and decided you were dying from that rash? Surveyors are doing the same thing with analyzing data from the mathematics view and not from the boundary law principles view.

    It’s not all just about the location data

    High-precision GNSS locations (and conventional data) we collect as surveyors needs to be included with the analyzation of the historical data from the legal side of the survey. If we didn’t find the original points, did we find ones that were substantially close to where the originals were? Were any of the original conditions at the time of the survey still intact? Bearing trees? Buildings? Any reference ties? What most surveyors tend to forget well is that all measuring devices (and I do mean ALL) are not the same, no matter how close they are manufactured and calibrated. Couple that with mistakes/errors/blunders I spoke of earlier, and here is your recipe of inconsistencies between surveys. You will say your instruments and devices are in top condition, so your data is right and the previous surveyors obviously messed something up. The unfortunate thing is that almost every surveyor makes that statement and we all are wrong to some degree. The bottom line is that while we may collect a ton of data with the upmost precision, it may not be accurate with the intent of the project, which is to retrace the original survey to the best of your ability. I’m not advocating that we dump our fancy robots, our very handy RTN networks or my shiny new UAV; instead, let’s get back to the basics. As Don Wilson notes in his preface of the new book; “One of the biggest differences between the surveyor relying on principles and court relying on precedent is that courts continually revisit the reason for the rule, or the decision in the previous case, to ensure that it applies, and fits the issue.” What I am advocating is that we remember the duties of our role and utilize the necessary tools to perform and deliver to the best of our abilities. I’ve had mentors and teachers that relied heavily on the math and not so much the true legal definitions. That means we need to brush up on the law and precedents that have been established for various situations and reasons. It will be through continuing education of our everchanging profession that will open more surveyor’s eyes to what the role of the surveyor was truly meant to be. With no disrespect to the GIS world, surveyors don’t aspire to be a map makers or database managers. We are professional land surveyors and our duty to our clients includes professionalism and the completion of an accurate land survey through precision measurement and analysis. Just as long as we follow those footsteps…

  • Satlab announces SLX-1 multi-application receiver mobile upgrade

    Satlab announces SLX-1 multi-application receiver mobile upgrade

    Swedish-based survey and GIS equipment maker Satlab Geosolutions has upgraded its multi-purpose multi-frequency GNSS receiver.

    SLX-1 receiver by Satlab.

    The SLX-1 was initially released as a CORS receiver but is now able to function as a mobile sensor suitable for any application where a rugged multi-application GNSS receiver is required.

    Based on embedded Linux operating system, the SLX-1 is a true multi-user and multi-tasking solution. The CORS design is ideal for long unattended and continuous operation and its mil-spec construction makes it ideal for mobile operations in the most rugged environments.

    The receiver tracks GPS, GLONASS, BDS, GALILEO, QZSS and SBAS constellations and can maximize the tracking to observe all visible GNSS satellite signals, thereby providing maximum performance for accuracy.

    With in-built Ethernet, 3.5G wireless, WiFi, Bluetooth and multiple serial communications for data transmission and/or reception, as well as a 64GB (expandable) internal memory, the receiver can simultaneously transmit/receive corrections while recording raw data in multiple sessions.

    The SLX-1 supports real-time TCP/IP, Satlab internet RTK and NTRIP in both server and client modes, as well as external radio Tx/Rx, making it compatible with most modern GNSS receivers on the market.

    With high performance precision GNSS measurement techniques, direct-millimeter accuracy with the highest levels of quality assurance is obtained. CMR, CMR+, sCMRx, RTCM2.x, RTCM3.x, RTCM32 and Binex differential formats, as well as Rinex and Raw data logging/output, are all supported so the receiver can be easily integrated into existing CORS networks, SatLab’s VRS NRTIP Caster Software or SatLab’s proprietary intRTK Cloud service. Equally, in Rover mode, it can easily connect any existing correction network or single-base source using any of its inbuilt communication modes.

    Control of the receiver is easily achieved by logging into the internal Web server either remotely or direct connection using Ethernet port or the inbuilt Wi-Fi hotspot. In Rover mode, real-time NMEA messages can be sent via any of two RS232 or single RS485 ports or via Bluetooth. It also has an external clock interface, event marker and PPS output.

    With a rugged anodized aluminum alloy metal case, internal lithium battery for up to 24 hours independent operation, two lane external voltage inputs with range 7-36VDC and PoE, the SLX-1 is designed to stay on regardless of environmental factors. If power is lost, once restored the receiver will reboot using the last settings and continue working normally.

    “This is an exciting upgrade to our popular SLX-1 CORS receiver, and now adds true multi-functional performance for both base and mobile operations to our increasing range of GNSS mobile products,” said Bjorn Agardh, CEO of Satlab. “The simplicity yet sophisticated capabilities of the SLX-1 combined with our free internet RTK global server services makes provision of correction data seamless and simple.”

    The mobile upgrade for the SLX-1 receiver is available now with a simple firmware upgrade that is available for free download and continues the promise that, there are no hidden costs of ownership with any Satlab product.

  • TerraGo Magic enables design of custom applications without coding

    TerraGo Magic enables design of custom applications without coding

    Magic-Create-Note-Android-TerraGo-WWhile change is constant, one thing that has become standard is the use of handheld mobile devices. Smartphones and tablets are used by almost everyone and the professional surveying community is no different. The process of data collection for specific purposes often needs to be tailored to each project type, yet traditional surveying methods are not flexible in allowing customization easily.

    TerraGo Magic, a custom app designed for both iOS and Android platforms, simplifies the process of designing a custom application for specific clients and needs.

    Surveying firms can install this tool in their mobile device to enable the specific collection and sharing of important data that can vary as needed. This data can overlay Google and Apple Maps and allow attachments of images and video. Overall, the app avoids the time-consuming coding process, and could significantly improve workflow for many firms.

    Distribution for the customized app is through the App Store for iOS and Play Store for Android.

    A free webinar on Thursday, May 25 covers the TerraGo Magic App Platform-as-a-Service, which enables anyone to rapidly build private-label, custom Trimble apps without the expense of traditional app development and without writing any code. Users don’t need hours of training or professional development skills to do it. Using a zero-code enterprise app platform, users can create, build and deploy custom mobile app for any industry or workflow in minutes.

    The webinar covers:

    • creating custom mobile apps with branding and selected features using a click app studio
    • integrating custom mobile apps with Trimble GNSS and many other enterprise platforms
    • publishing to the AppStore, Google Play and the cloud with
    • deploying cloud-based or private-hosted enterprise servers
    • reducing development costs

  • Timesaving webinar on survey data collection

    Time has great impact in the enterprise mobility continuum. Developing tools for mobile workers has long been the sole province of IT, but the demand for mobile apps is stretching IT to the breaking point. Demand for mobile apps is five times greater than IT capacity, according to one market study.

    This makes many organizations reluctant to jump in to mobile development or to change traditional processes that aren’t broke — so why fix them? The trend also explains the emergence of zero-code app development platforms that can reduce a one-year IT backlog to a few hours. The equation changes when end users become “citizen developers,” allowed to create the custom apps by selecting features, interfaces from a menu of capabilities.

    Zero code is being called both a game-changer and disruptive technology because it offers a new approach to mobile data collection, with new, easy-to-use technology to develop tools.

    One such example is Terrago’s Magic, a zero-code development studio, which is growing both vertically and horizontally, with both directions responding to customer input.

    GPS World readers and all other interested parties have an opportunity to learn more about these time-saving tools in a free webinar on May 25: How to Build Custom Trimble Apps for Any Industry with Zero-Code. See env-gpsworld-integration.kinsta.cloud/webinar for further details and immediate registration.

    Participants will learn how to:

    • Create custom mobile apps with your branding and selected features using a click-not-code app studio;
    • Integrate your custom mobile app with Trimble GNSS and many other enterprise platforms;
    • Publish to the AppStore, Google Play and the Cloud with the click of a button;
    • Deploy cloud-based or private-hosted enterprise servers; and
    • Reduce development costs by 90 percent.

    Vertical growth comes through a software development process that generates a new version every 4-6 weeks, each with new features. Magic custom app development basically involves selecting workflow elements from a menu. Since anything with a menu is limiting by definition, TerraGo does not claim that Magic can be all things to all people. But as limitations are reduced with each version’s new menu, Magic is becoming more things to more people – and can complement less-limiting (if more time and money consuming) low-code app development organizations by reducing the strain on their IT departments.

    Horizontal growth is coming through partnerships with companies such as CompassTools and Duncan-Parnell.    These firms have the vertical expertise to customize and deploy tailored solutions at speeds not achievable with traditional approaches.

    CompassTools, headquartered in Denver, serves eight Midwestern states from Canada to Mexico with high-precision field data collection solutions. For many years Compass offered handheld GPS devices as the foundation of those solutions with great success. Still, the data typically required manual processing once the devices were returned from the field, introducing expensive delays. Now positioning, mobile and cloud innovations are reducing that time.

    “We really believe that TerraGo’s approach represents an important part of the future data collection tools that our customers are going to need in the field,” said Andew Carey, an account manager with CompassTools.

    “Because TerraGo apps provide direct integration with Trimble receivers, they can help us deliver the best of both worlds for customers with easy-to-use field apps and proven Trimble accuracy,” said York Grow, MGIS solutions manager at Duncan-Parnell.
