Import maps
There are four ways to import maps files into the project:
1. Load from text file
2. Load from CPS-3 grid file
3. Load from ZMap grid file
4. Load from IRAP classic grid file (*.irap / *.gri / *.txt)
In Data manager in Maps icon decide in which set of maps data will be loaded. Press right mouse button and choose one of three options:

The CPS-3, ZMap and IRAP classic grid loaders let you select several files at once in the load dialog. Each selected file is imported as a separate map into the chosen set of maps. The plain text-file loaders load one file at a time.
