[Geoserver-users] Issue Setting Origin for WMTS Tile Matrix Set

Hi All,

I’m trying to define a Tile Matrix Set for https://www.linz.govt.nz/data/linz-data-service/guides-and-documentation/nztm2000-map-tile-service-schema. But I’m having some trouble trying to set the origin correctly to get the correct WMTS TileMatrixSet TopLeftCorner defined for each TileMatrix entry. I need each zoom level to define TopLeftCorner as the origin of the tile grid i.e 10000000.0 -1000000.0, but when I set the min X = -1000000.0 and max y = 10000000.0 I get a WMTS capabilities document with the following:

At the moment I have setup the grid as per this screen shot:

I’ve defined this same grid in other software before, like mapproxy and it’s worked ok.

NZTM:
srs: EPSG:2193
origin: nw
bbox_srs: EPSG:2193
bbox: [-1000000, 3087000, 3327000, 10000000]
res: [8960, 4480, 2240, 1120, 560, 280, 140, 70, 28, 14, 7, 2.8, 1.4, 0.7, 0.28, 0.14, 0.07]

Any help would be greatly received.

Cheers,
Jeremy
