I just started unity few hours ago, can I import my raw file in unity in a simple way??

I’m trying to make a Geographic information system application. I need to get my DEM(Digital Elevation Model) raw file data and map the png image files on it. Can unity read the raw data?

You need to transform your DEM into a FBX format file and then Unity will be able to read the data, to map the png image you will need some programming skills.
