How to Remove “Bad” Data in Pathfinder Office Before Exporting to GIS or CAD

Try as we might to setup our data collection software correctly and use a repeatable field data collection protocol to collect high accuracy data, there’s not much we can do to prevent GNSS errors from creeping into our features. The only users who can almost avoid this are those who perform their field work in […]

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 […]

Elevation Matters: High-accuracy GNSS for Dam Inspections

When an application for GNSS requires highly accurate relative elevation readings for a set of features, we often think of fairly traditional surveying techniques and equipment like survey-grade GNSS systems, total stations, or even the old hand level with a stadia rod.  But when that structure is way out in the boondocks far from any […]

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 […]
