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 […]

The New Trimble R1 GNSS Receiver is Small but Powerful

Smart devices such as iPads and Android tablets are becoming more and more popular for collecting GIS data in the field.  They are affordable, readily available, and powerful and offer benefits that GIS folks like such as a larger view for displaying imagery and completing an attribute form.  The “tablet craze” as you might call […]

Elecdata Hits the Skies with the Trimble UX5

Unmanned Aerial Systems continue to make the news almost daily and we at Elecdata are anxious to see the FAA open the skies up to commercial use of the technology for mapping and surveying.  The FAA has said it will release an initial draft of regulations for operating small drones (sUAS) by the end of this […]

Is My Integrated Camera Good Enough For GIS?

That is an interesting question and not an easy one to answer. We can start by clarifying that standalone digital cameras take the best pictures. That is clear! Many of today’s smartphones and tablets with their miniature lenses do amazingly well too. What if we look at the picture quality needed by GIS professionals? Do […]

Enabling the Trimble Positions Desktop Add-In

Occasionally, users are encountering difficulties enabling the Trimble Positions Desktop Add-in. The issue arises when the user tries to enable the extension after a successful install of the add-in. Please check out this short video for more information:  

The Esri ArcMap Plugin for Trimble TerraFlex Scores! The Good Guys Win Again!

It is such a welcome feeling knowing that you can pick up nearly any device, be it smartphone, iPad, Android device or full Windows tablet and venture into the field for attribute driven GIS data collection.  In some ways, it’s a little dangerous to give in to the temptation to use a smartphone to GPS […]

California Wildfire Season Lingers Long After Summer Ends

At the time of year when most of us here in Northern California (I’m located in Sacramento) are looking for temperatures to “dip” into the 70’s, we are dealing with an unprecedented heatwave leaving us with very summer-like temperatures in the mid-90’s. Having unseasonably hot weather is one thing, but add that to our record […]

The Latest Functionality in Esri’s Collector App and Trimble’s TerraFlex Software

Have you seen what’s new in the smartphone GIS data collection apps?  Here’s a quick overview of a couple of the highlights, and look for our detailed comparison coming later this month. In Esri’s Collector App, the search button now allows you to search for features in your map.  They have added the ability to […]

Should I Post Process My GPS Field Data?

The answer to this question may seem obvious. We all want to get the best data possible when using a GPS or GNSS receiver, right? So how can we accomplish that? Many of us are happy with real time corrections. But, what if real time corrections are not available? In North America, most of us […]

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 […]
