Re: New cloud platform for GPR processing

ADobrovolskiy - Your SEGY doesn't appear to be a standard format in the way it stores the Lat/Long data. We're working on implementing your format now and will update you shortly. OK, thank you. In this variation of SEG-Y coordinates with standard precision are stored in bytes int16 coordScalar = -...

Re: New cloud platform for GPR processing

Could you check how it works with attached profile?

It seems that it was not imported correctly.

"Native" application is Prism2 or Geohammer.

Re: Guess what's in the GPR profile

yes, now file imported without issues it seems that antenna was elevated approx 2m above ground? Are you experimenting with drones? shape of "long" hyperbola corresponds to surface target at the distance ~7..9m from the survey line. It can be a tree, pole, something. prism2.png hard to say what is b...

Re: Guess what's in the GPR profile

Hi, could you upload the data file?
Large hyperbola looks like a reflection from something on the surface. What antenna do you use?

Re: Airborne ground penetrating radar

The answer is speed and safety. Please check this sample - https://files.ugcs.com/s/PeKeXEDZzGwD6bC It was 2 flights 15-20 minutes each. Another sample - past summer we did a magnetic survey with a drone - 50km of survey lines with altitude 3-6m AGL and 5-10m between survey lines in Greenland over v...
