I am looking for a tool to sketch changes to Earth. It should start with a geoid or an Earth model, rise/lower/flood selected areas. "Heal" boardersk: if an island is added in an ocean height shouldn't abruptly change from 0 $m$ to $-$1000 $m$. It should also measure distances between points, allow labeling and export maps of selected images as raster graphics (jpg image).
So far I could do two things:
- Start with Google Earth, prepare necessary shapes using flooding, paste results as layers in Gimp/Photoshop [fast and ugly]
- Import data in Matlab, define rules for modified regions, export [manual rule definitions is slow, no way to smart select, drag and drop regions]
What is the standard approach to do this? For instance, how people display flood plains, draft a channel or a new island project?
Windows/Mac/Linux/doesn't_matter? Windows preferred, Linux is OK. GUI or also command line? GUI, or GUI+CLI batching. CLI only is undesired. Go you want to use a GIS? I didn't know about GIS. Looking into in.
