As Quaz has been banned (and I heard he got some problems IRL too) I will take over the mission to create the map.
To Quaz, I hope you get your problems fixed IRL, you seems like an good person in general.
I will be using an current map I have that has all official gta sa singleplayer locations. And after that I will keep adding all other locations that has been suggsested already.
I will not:
Add state cars, reason stated below.
Player's houses.
Specefic road names, like E45 for example (not official, just an example)
I have seen an map that gives names to every single road according to the signs in gta:sa singleplayer, however they won't be added since it will clutter the map with to much icons.
As an added bonus, I will make an complete .rar file so you can use the modified map INGAME! This means changing the ingame menu map and the Radar itself (however they can't be seperated from eachother so you need to have both changed for it to work).
Stay tuned, the map making process will start right now. Keep suggesting locations. To make it more easy to me. Please download this picture:

All official singleplayer locations (like the casinos, Police stations etc) is not neccessary to tell.
This means all icons found on this map:

EDIT: All Gas stations have been found, will add them.
