Property talk:Has x coordinate

Like actual coordinates?

I don't think these coordinates (this page for x as well as Property: Has y coordinate) line up to Tyrian lore for longitude and latitude (as explained in the Sea of Sorrows novel). Do any of these coordinates hint at a 'zero' location? (If they lined up with the lore, one coordinate says Arah is the location of 'zero,' and one says Rata Sum is the location of 'zero.' With that in mind, a lot of these coordinates do seem to have wildly different x and y coordinates.) Can they be plotted on a map of Tyria? Are they similar or related in any way to the mysterious 'units' used to determine distance? Or are they just random numbers? Thanks in advance, ~~TiffanySmith.8216 11:46, 10 August 2021 (UTC)

Good question. I've never heard of the lore coordinate system.

There is a documentation page to answer questions about the mapping system: API:Maps - I think this would be use to your understanding. 1 coordinate = 24 inches, which is the same as the ingame tooltips report when stating "units" -see the Trivia section on that page.

These coordinates are either straight from the API as reported by the official API endpoints (such as API:2/continents, API:2/maps or API:2/wvw/objectives) or by calculation via the MumbleLink coordinates.

There is also a project page detailing how to get coordinates for anything ingame, see Guild Wars 2 Wiki:Projects/NPC Coordinates/Guide.

In terms of what we do with coordinates on the wiki, all the interactive maps utilise the API coordinate system.

The Has x and Has y coordinate properties are simply a crude way of tracking which NPC's we've added interactive maps to (in the infoboxes). -Chieftain Alex 21:14, 10 August 2021 (UTC)

There's also this image --> (which demonstrates the API coordinate system would be 0,0 to the northwest of Divinity's Reach, totally different in direction to the lore system). -Chieftain Alex 21:17, 10 August 2021 (UTC)

(Edit conflict) I didn't know there's coordinate lore. If that's it then they don't line up with the lore indeed. And they don't have to either, they're only of technicall nature. They describe two dimensional points in the three dimensional coordinate system the game uses for everything. And the wiki uses these coordinates to show the location of POIs, events, collection locations, etc. on maps in infoboxes and map sections. (Which i suppose is (at least indirectly), though i'm not sure if it's in the sense you're meaning, plotting them on a map of Tyria.)

As for the zeroes; there's multiple coordinate spaces employed, a map and a continent coordinate space. The locations as you can find them specified in the source of wiki pages are in the continent coordinate space. The map coordinate space, like the name implies, is local to a map and every map has it's own coordinate range with the thing they have in common being zeroes in the center of the maps bounding rectangle and the zero for elevation being level with the water in the area. The continent space has its zeroes in the top-left of the world map that shows all maps together. The API provides, among other things, the coordinates for POIs in the map coordinate space and the bounding rectangles of the map and its position in the continent coordinate space for translation between the two. The MumbleLink file also provides coordinates.

So as you can see the're not random numbers but provided by mumble or the API. But they are the "mysterious" units refered to by e.g. skill descriptions; though they may need some conversions from on unit to the other depending on where you're taking them from before they match the in game units i suppose.

Also see gw2timer.com for an interactive map of Tyria with the coordinates in the bottom left (they correspond to where your cursor is pointing). --BuffsEverywhere (talk) 21:26, 10 August 2021 (UTC)

Or see Map#Interactive world map which does the same with the position last clicked on the map. Nightsky (talk) 21:46, 10 August 2021 (UTC)
