How to get an AutoCAD Drawing into TerraSync as Background File

During the course of providing training for our customers who purchase a GNSS mapping system, we often get asked, “How do I get my AutoCAD drawing into TerraSync?” Depending on how AutoCAD is used, the drawing could have a known spatial reference or it could have an arbitrary coordinate system defined as the lower left […]

High Accuracy GNSS in Today’s Common GIS Workflows

Today’s field users and GIS folks now have more choices than ever regarding tools for field data collection. It makes sense that collecting data in the field is relatively easy given all these choices and the ability to use common devices like phones and tablets. Add in geopdf viewers and simple to use apps for […]

Comparing Techniques to Link or Attach Photos to GIS Field Data

How do I take photos in the field and link them to my GIS data in the office?  There have been so many techniques and options over the years that it’s difficult to keep track of the solution that’s right for you.  The technique you use will depend on the field software you are running. […]

Differential Correction Sources: SBAS, RTK Base Stations, and Real-time GNSS Networks

We get a lot of questions about how to improve in-the-field accuracy with GNSS equipment.  Many new or less-experienced users suspect that when a device is marketed to provide 10 cm or 1 cm level accuracy, that it provides that right out of the box.  When you pay a pretty penny for a high-end machine […]

Renting Trimble Equipment vs Buying

Rent or Buy: The Trimble GPS Debate

  Before coming to work at Elecdata I coordinated field crews where we used Trimble GPS equipment for field data collection.  We used the equipment daily from May to September, but then most of it sat on a lonely shelf during the off-season.  Each spring we went through the commotion of verifying everything was still […]

How to Choose a Single Base or VRS Subnet in Oregon or Washington to Receive Real Time Corrections for High Accuracy Mapping

For those of you using GNSS surveying or mapping systems in Oregon or Washington, you have access to real time correctors via cellular modem or cell phone to a comprehensive network of GNSS base stations, providing there is cellular service somewhere near your project site. VRS Information A VRS, or Virtual Reference Station, is a […]

A Few, Simple Best Practices for Collecting GNSS Data Using Trimble Handhelds

  Collecting high quality GNSS data in the field is simple.  Well…..maybe that is understating things considering you can attend a prestigious university and receive a graduate degree on the subject.  Certainly there is a lot to consider when working with GNSS technology as a whole.  The best approach is to narrow down the subject […]

Where Can I Find Help with ArcPad, TerraSync, or my Trimble Device?

Mapping with professional-grade GNSS equipment can be a valuable tool, but it is amazing how many of us do not realize the full potential of the system we have.  Given the high-dollar investment, we expect performance, especially positional accuracy, to be superior to that of a recreational device we can buy at our local sporting […]

Esri’s ArcPad vs. ArcGIS Mobile vs. Trimble’s TerraSync vs. TerraFlex

In mapping and GIS there are several software solutions for collecting and processing your data. At first glance they might seem similar, but in fact have many different features. Here we have broken down these four software choices and compared hardware support, software features, GPS support, data collection, GIS support, and data maintenance. Esri’s ArcPad […]
