maunaloa Posted August 6, 2011 Report Share Posted August 6, 2011 Hi PPL! I'm working with guys, who scanned some territories with GPR (ground penetrating radar). This device collecting many-many datas from the reflected radar waves. The datas are collected by layers, commonly by every 20-50 centimeters. If ya want to find any infrastructural element or archeological thing, ya need to examine these layers. I want to ask ya, anyone tested any ArcGis extension, to view ground radar datas or any seismic datas? This is a bit new for meh, i don't know, how big is a GPR raw data, and how it's look like:) Quote Link to comment Share on other sites More sharing options...
Administrators EmperoR Posted August 7, 2011 Administrators Report Share Posted August 7, 2011 Radar raw data cannot directly open in GIS software, you need software that can transform SAR Raw data into ready image data that later can be analyzed via ArcGIS most advanced is GAMMA SAR, or you can use Sarscape from ENVI or ERDAS SAR Suites Quote Link to comment Share on other sites More sharing options...
urthok Posted August 24, 2011 Report Share Posted August 24, 2011 He didn't ask about that kind of radar. He wants to know about GPR, a geophysical method. Can't answer your question though. Try talking to a geophysicist, or an environmental geologist. Quote Link to comment Share on other sites More sharing options...
maunaloa Posted August 25, 2011 Author Report Share Posted August 25, 2011 Once i've participated in a georadar survey by an archeological site. Came 3-4 scientist guy, and brought a device. They pulled that device on the ground, and a display showed the penetration-reflection diagramms. Every measurement was made along a line. Two surveyor measured the real coordinates of the line start and end point. With a GPR analyst software they can combinate more measurement zone, so they can make an image about a wide are (scanned with 3-4...x georadar line), and can export that image. Every measurement, what made along a line, is a multi-depth measurement. By our site, the max scann depth was circa 2,2 meters, and every output images made by 10 centimeters. I show you a sample image. Btw, i don't know more about that subject, i only wanted, how can i, or what can i display in a GIS software from a GPR raw data, or any processed data.

Lurker Posted August 25, 2011 Report Share Posted August 25, 2011 what the format of the file? maybe there is a conversion method Quote Link to comment Share on other sites More sharing options...
maunaloa Posted August 26, 2011 Author Report Share Posted August 26, 2011 Atm i dunno what is the format. In a short amount of time will be a new georadar survey action, and i will talk about that with the surveyors. Quote Link to comment Share on other sites More sharing options...
Lurker Posted August 26, 2011 Report Share Posted August 26, 2011 hem, i think its suitable if you use geophysical software than general GIS software like Arcgis I have a friend that use geoelectric tool to get soil moisture stratification, and seems when I saw the data, its difficult to plot it in ArcGIS try something like ENCOM DISCOVER (Mapinfo Plugin) or any gephysical plugin software that compatible with arcgis ArcGIS only suites for Surface data or near surface, CMIIW Quote Link to comment Share on other sites More sharing options...
contiki Posted October 4, 2011 Report Share Posted October 4, 2011 GPR data have to be processed first (filtered, enhanced), then converted to image files (jpg, bmp, tif etc) and only then you can import those images as "slices" in some software that can create 3D representations using those "slices". An alternative solution is to define coordinates in every "slice" (relative will do) and use the nviz module of GRASS GIS to make a 3D representation of those "slices" (GPR recordings).
