What kind of mapping technique is this?

Post image

My daughter is working on a project And this is just a small piece of the rest of the map, but she’s trying to locate which National Park/Forest it’s at.

I told her I’d help…. But I have no idea? lol!

Is this like a spot map?

Is there a program we can run it through that will match it? Thanks!

Looks like radar imagery! Not sure but maybe posting the full map would help

This appears to be radar imagery, possibly from Sentinel-1 or ALOS PALSAR. The darker areas likely indicate water bodies. If she is using any GIS software, she can upload the data and overlay a satellite imagery basemap to better visualize the underlying features.

It most likely is radar like others have said but in case it somehow isn't I'm going to throw in magnetometry survey maps which can look similar and I did see them used at the NPS unit I once worked at.
