Source Data & Coordinate Calibration
This report explains what our map can legitimately reuse, how coordinate imports are transformed, and what remains unconfirmed. The maps themselves are the Team Jura interface; none of these sources grant ownership of Rockstar game artwork.
1 · GTA V Story conversion
The old danharper/GTAV location data reports Leaflet map projection coordinates as geographic-looking latitude/longitude. They are not Earth coordinates. Using eight identified spaceship-part pairs cross-checked against the independently published GTA V game X/Y list, we derived an affine mapping from Leaflet's Mercator Y and map longitude to GTA world X/Y.
X = 103.22126231 × longitude + 12851.6855908 M = ln(tan(π/4 + latitude × π/360)) Y = 5913.52505828 × M − 10162.16009065
Eight fitted control points had an RMS residual below 0.4 world unit. Six geographically separated holdout locations, including spaceship parts #17, #20, #24, #30, #40 and #50, differed by approximately zero to two units from the comparison coordinates. This validates the projection transformation to that reference precision, not item-by-item game playability or numbering.
| Independent spot check | Reference game X, Y | Converted X, Y (rounded) | Difference |
|---|---|---|---|
| Spaceship Part #17 | 1,226; −1,115 | 1,226; −1,114 | 0, +1 |
| Spaceship Part #20 | 1,126; −2,612 | 1,126; −2,610 | 0, +2 |
| Spaceship Part #24 | −1,229; −3,506 | −1,228; −3,504 | +1, +2 |
| Spaceship Part #30 | −920; −1,174 | −920; −1,173 | 0, +1 |
| Spaceship Part #40 | −2,798; 1,430 | −2,798; 1,431 | 0, +1 |
| Spaceship Part #50 | −412; 6,098 | −412; 6,098 | 0, 0 |
Comparison source: OutlawDB GTA V spaceship-part guide (consulted for independent coordinate facts, not copied as a complete database). The converted set uses its original community item labels, which may not match other guides' numbering.
2 · GTA VI Leonida pixel conversion
Mapheist expressly publishes its trailer-based research under CC BY 4.0. Its leonida_x and leonida_y are pixels on the 32,768 × 32,768 YANIS v16 community map. Atlas uses the GTADB coordinate center of 16,384 and positive Y north:
X = leonida_x − 16384 Y = 16384 − leonida_y
We tested this convention against GTADB landmark coordinate matches in Vice City: Mapheist's W South Beach community location falls about 60 world units from the near-matching GTADB landmark; Sahara Arena falls about 24 units from its matching GTADB location. These are independent map revisions and approximate scene locations, not precision-verified in-game pins. YANIS v16 and v17 may place features differently. Every imported mapheist record remains PROVISIONAL, even when a game name is visible in official footage.
3 · GTA V & Online base-world objects
MiniMaps for FiveM explicitly offers machine-readable game-object coordinate lists for reuse. The selected ATMs, fuel/air pumps, bus stops and radio mast records already carry GTA world X/Y values, so they require no additional coordinate transformation. These are map-prop locations, not guarantees that a player can interact with a prop or that GTA Online's world matches Story Mode in every instance.
4 · Attribution and source behavior
| Source | Rights / rule checked | What Atlas actually does |
|---|---|---|
| GTADB.org | CC BY 4.0 (code MIT) | Loads community landmarks and map tiles from GitHub repository, NOT live production. |
| danharper/GTAV | Public repository with WTFPL license | Retrieves historic Story Mode locations and converts their projected coordinates. |
| Mapheist.com | CC BY 4.0 data; Rockstar images excluded | Loads trailer research pins with provisional labels. |
| MiniMaps for FiveM | Publisher explicitly allows copying/embedding JSON | Loads selected base-world object coordinate groups. |
| GTAWeb.eu | No blanket data/image license established | Used for feature research and troubleshooting, not bulk copying. |
External JSON downloads may be blocked by network access, browser CORS rules, or a source changing its schema. Atlas displays each source's state and leaves the main GTADB map usable even when an extra feed fails. Source data is cached in your browser after successful download. As of this build, a local browser test cannot establish that every external host will remain accessible to every visitor.
