  • SuperSurv mobile app increases RTCM 3.1 support

    Makers of the mobile GIS app SuperSurv, developed by Supergeo Technologies Inc., are working to increase its GNSS positioning functionality.

    In recent weeks, the SuperSurv product team began to enhance SuperSurv’s NTRIP solution, aiming to adopt more RTCM versions and provide a better GNSS positioning service. NTRIP (Networked Transport of RTCM via internet protocol) is a protocol to send GNSS-related data through the internet, which enables users of differential GPS or network RTK to get correction parameters after connecting to the internet. The correction parameters can be used to calculate a more accurate GNSS location.

    Supergeo’s product team is developing the support for RTCM 3.1, including Type 1021 and 1023, two kinds of messages. Type 1021 contains the seven parameters for 3-axis coordinate transformation — three for 3-axis translation, another three for 3-axis rotation and a scale factor.

    Through the original projection method, users can only get rough coordinates. However, with NTRIP solution, users can send the current location to the server and then receive the parameters provided by it. This makes it easier to obtain a suitable local coordinates frame for more precise coordinates.

    The Type 1023 message provides more accurate grid residuals. By establishing a 4 x 4 mask window around the rover, users will receive the 3-axis corrections within these 16 grids. Accordingly, a more accurate GNSS positioning is achievable after interpolation.

    After completing the development, this technique will be implemented in the current version, SuperSurv 10.1. Combined with SuperSurv’s existing GIS features, Supergeo believes the newly supported RTCM 3.1 will bring a brand-new experience to fieldworkers.

    Launched in November 2017, current version 10.1 offers three major new features, including snapping, coordinate system customization and Layerset. Google Maps and TIFF are also supported.

    Supergeo’s product manager for mobile GIS, Zara Yu, recommend that users activate the point-data auto-collection with RTCM 3.1. This method not only helps users skip repeated operations but also enhances the data quality and efficiency.

    SuperSurv can be downloaded and tried at no cost. Online tutorials are also available.

  • Connect with Bluetooth GNSS Devices Using SuperSurv

    SuperSurv_measureTo meet the needs of high-accuracy field data collection and better workflow with modern GNSS technology, Supergeo’s latest SuperSurv GIS mapping app allows users to connect with and operate external Bluetooth GNSS devices. The app also elevates field-work efficiency with new averaging algorithms.

    SuperSurv is designed for field data collection on Android and iOS-powered devices. Integrating with GIS and GPS technologies, SuperSurv provides functions like Map Display, Query, Measure, and supports to overlay OpenStreetMap as the basemap. Also, users can capture point, line and polygon features and attribute data, and save the data as SHP or GEO format in both offline and online modes.

    With the new external GNSS device connection function, users can choose between internal positioning information and an outer GNSS source via Bluetooth. When pairing the GNSS receiver with an Android device, SuperSurv allows users to fully control and present detailed messages of navigation within system status. In addition, data collection via GNSS is enhanced with options such as a coordinate data averaging function or vertex collecting threshold, bringing users modernized and highly accurate field survey experience.

    The external GNSS device connection and advanced data-collecting functions are fully supported and available with the SuperSurv Pro version. For SuperSurv M3 users, the newly added functions come as an optional plug-in that users can purchase and download.

    Free trials of the software are available:

  • Smart Mapping SuperSurv Available on App Store and Google Play

    SuperSurv-2Supergeo Technologies, a provider of GIS software and solutions, has launched SuperSurv, a mobile GIS app, on the App Store and Google Play.

    SuperSurv contains comprehensive GIS data-collection functions. Designed for both iOS and Android powered devices, it integrates with GIS and GPS technologies to provide functions in field survey, such as Map Display, Query, Measure, etc. With SuperSurv, the collected data can be saved as feature layer (point, line, polygon) in SHP or GEO format in offline mode. SuperSurv supports OpenStreetMap as the base map.

    SuperSurv has been successfully applied in various industries worldwide, including environment protection, pollution prevention, and facility management. The free trial version is now available on Apple App Store and Google Play, allowing users to experience complete functions for seven days before purchase.

    SuperSurv-1For users in North America, Supergeo has released the SuperSurv M3 version to provide easy-to-use and useful data collection and map display functions. SuperSurv M3 supports feature-layer display and offline editing functions. Furthermore, cached maps can be adopted as the base map to facilitate data capture tasks.
