and another...
Think I have a very large island on my server, full of roads and building and soo...
But, it's outside the map area, it's not seen on the map, and if you go there, you'll not be able to see where you really are.
You cannot see the roads and blocks on the mini-map, and the big map shows you standing on the map border instead of your real position.
My suggestion, however it's a bit difficult and needs a bit of change in SAMP's connection protocol, is to send some static data from the server to the client that indicates the objects that are needed to be rendered within the map.
Like as in GTA SA Detailed Radar, SAMP needs to render the objects by looking from upside. I don't think it would need a lot of data transmission or high level graphical processing by the client, my only concerns are,
How to expand the map textures? is it possible or we need to shrink the map?
And what if someone uses a custom map texture which doesn't really suit the rendered objects' style?

I hope my suggestion is useful and practical, and these concerns have a good workaround ^^
