Local catalog of GTA San Andreas and SA-MP object IDs. Rows come from the public GTA Stuff model export and the public placement list. Nothing in the catalog was invented to fill a gap.
The satellite map is the GTA Stuff image calibrated to world coordinates from -3000 to 3000 on both axes. North is up. Gang-zone numbers are those world coordinates.
Game DFF, TXD, and COL binaries are not included. The 3D view draws the measured bounding box until you open a DFF from your own disk. Fifty thumbnail URLs returned 404 at download time, so those cards have no preview.
