DGPS Receiver GMS-100


Topcon's new GMS-100 GIS data collection system is designed to make the most of your time in the field no matter what your level of GIS expertise. By combining ESRI's ArcPad software with a precision GPS receiver and real-time differential correction, the GMS-100 allows you to literally take your GIS into the field to make data collection more accurate and efficient. From natural resource mapping to building and maintaining spatial databases for large utilities, the GMS-100 is no ordinary GIS package.

The Topcon system lets you map virtually any type of feature you encounter-points, lines, and areas quickly and accurately. With ArcPad software you can easily create custom data collection windows that allow you to capture attribute data in a format fully compatible with your GIS database. Once you've collected new features, you can immediately see them mapped along with your GIS data. Back in the office there's no need to convert to GIS compatible data formats because all of your work was done in Shape file format, the industry standard for GIS.

Accurate position data is a critical element in collecting data to populate your GIS. With Topcon's advanced GPS receiver technology, positions accurate to less than sub-meter can be collected under even the most demanding conditions including under trees or in mountainous terrain. The real-time differential correction signals collected with the fully integrated radios ensure that the position you see on the data collector display reflects your actual location. This makes navigating and relocating features a fast and simple process.

The GMS-100 is available with a Compaq iPAQ Pocket PC or a ruggedized data collector for work in harsh environments. Both of these data collectors provide large, backlit displays that can be viewed under any conditions from full sun to complete darkness.

The Topcon tradition of accuracy, productivity and innovation is alive in the GMS-100 system. From the rich, intuitive ArcPad data collection software to the precision GPS receiver, the GMS-100 will help you meet all the challenges of building your GIS database.
