WMTS topLeftCorner axis orientation
daliborjanak opened this issue · 2 comments
TopLeftCorner in tileMatrixSet defines two coordinates (x, y). In some coordinate systems like 4326 which has different axe orientation are the coordinates switched (y, x).

OL3 implementation:
https://github.com/openlayers/ol3/blob/master/src/ol/tilegrid/wmtstilegrid.js#L101
Proj4 4.8+ implementation:
https://trac.osgeo.org/proj/wiki/GenParms#Axisorientation
(updated) Implementation details discussed in MapTiler repo.
MapTiler will add into metadata the flag: axis:'xy' or axis:'yx' and WMTS implementation inside of TileServer-PHP will respect it directly when constructing TopLeftCorner in GetCapabilities.
Finally we have removed axies parameter. The order of coords is based on type of system (geographic or projected). Tileserver is parsing it now from proj4 string if is provided. Implemented. Tested
