GPR-SLICE new option - scrolling of GPS radargrams in OpenGL with a user customized scan size
GPR/GPS surveying is becoming more commonplace and users are often collecting longer and longer single track GPS datasets. Shown is an example of a GPS (drone) track collected by Aero Solutions 360 in the Philippines. One issue in displaying GPS radargrams in their full 3D extent is zig-zag single track surveys are difficult to look inside the track as front or rear portions block the visualization.
For this reason a new scrolling option was developed in OpenGL for GPS radargrams. The user can set the number of scans to examine and then clicking the r+/r- buttons one can increment and display that number of scans into the single track. The Store button can also be used to keep display lists of any number of desired portions of the track and zscans or x/yscans etc. can be placed into the volume. The Bounce button is also engaged and will allow an "animation" of the GPS track to be drawn across the site. The animation will reverse itself after getting to end of the track.
