Has Anyone Used GIS and Remote Sensing to aid in fossil hunting?
Suchascenicworld posted a topic in Questions & Answers
Hello everyone! Fossil hunting is massive hobby of mine and I am trying to find new localities (that are of course, legal). I have a background in GIS and Spatial Analyses (albeit, working on completely different things!) and was thinking about using my geo-spatial skills to narrow down a few areas. In so far, I have layers dedicated to streams, bedrock, and DEM but I was curious if others have used GIS and remote sensing to aid in fossil hunting, and if so, are there any specific layers or techniques that you find to be particularly useful when searching for areas that may have fossils? Thank you!- 42 replies

Drone watches as landslide drags houses into the sea on the Norwegian coast
Oxytropidoceras posted a topic in Geology
Freak landslide drags several houses into the sea on the Norwegian coast as viewed by drone.
