GeoCue Group’s reference library articles covering a wide variety of geospatial topics related to our various product lines.
Aimed at surveyors and GIS professionals who use geodetic-quality GNSS equipment to determine positions for land planning, coastal monitoring and other purposes, this video from NOAA’s video library covers best practices for reducing errors in the areas of: 1. location and environment, 2. equipment setup and 3. observation times and accuracy checks.
Sometimes when troubleshooting it can help us if we can get a system information dump for your machine. We need the information to comb through your settings and installed programs to look for anything that may be at odds with other machines or our test machines. Follow these instructions to complete a dump. To bring up…
In the LIDAR industry the generally accepted definition for Nominal Pulse Spacing (NPS) is the one detailed in the USGS base LIDAR Specification. That is the spacing between points in the collection when in reference to single instrument, single swath, first return only LIDAR point data. The NPS is a value that is usually predicted by…
The LIDAR community has been gradually adopting the terminology “Quality Level” to categorize airborne LIDAR data. The idea is to use a simple scheme to characterize the more important features of a LIDAR data set into a few broad groups designated QLn where n is the quality level. LIDAR Quality Levels – Part 1

In the previous articles we provided an introduction to coordinate systems, geoids, datums and projections. This background information was needed in order to delve into more details on transformations and changing projections in the various software packages to help you do more with LIDAR data. This article will provide the information into transformations and changing…
