Hi, to lover of retro.
For starters, I think, you should find and look at old threads where answers on your questions are (may be).
At the beginning of 2006 year's
ref, distinguished modder, published their work - Terrain Editor for SH3. I advise you to carefully read this topic and all subsequent, related, in SH3 and SH4 Workshops... where
ref explains many things.

Unfortunately I have not found my replica to racerboy... I found only 2 pictures:
In my explanation to the racerboy, I was talking that everything can be done using Photoshop:
1) load a Terrain Map (eg 4320_2160.raw);
2) Convert channel to indexed color mode;
3) load palette file Terrain.act as Color Table;
... and you can working with image... and so on.
