[Geomoose-users] TMS layers in GeoMOOSE 3.x

[Brent Fraser]

Hi Mark,

Regarding Issue #1 (the tile id problem), try using

<url>https://geomoose.lyonco.org/lyonmapcache/tms/1.0.0/LyonPictoPhotos2020@GoogleBingArcGISCompatible/{z}/{x}/{-y}.jpg</url>

Note the {x}/{-y} order and the minus sign.

As for Issue #2 (the cross-origin problem), Jim would be the expert.  If you are in control of the tile server (and it is running Apache as the web server) you could try adding
Header set Access-Control-Allow-Origin "*"
to the configuration (as an example see https://github.com/geomoose/gm3-demo-data/blob/c29e41a341a300532984a4daeb26fa14bddc156a/docker/etc/000-default.conf#L14 )

Other possible solutions are:
-  serve the GeoMoose page from the same origin as the tiles, or
- put a proxy on the GeoMoose page server to get the tiles when requested and pass them to the Geomoose page.

Best Regards,
Brent Fraser

Brent and Jim,

Thank you for your replies.
I am using MapCache to serve out imagery in Web Mercator (GoogleBingArcGISCompatible). The Web Mercator tiles are working correctly in ArcGIS as well as QGIS when using WMTS. Unfortunately, I am still having a couple issues:

Issue 1:
*GeoMOOSE is requesting a tile that it out of range. I am not sure what is causing this issue:
GeoMOOSE is working with other XYZ tile servers such as OpenLayers.
MapCache is working with ArcGIS and QGIS clients.
The tiles requested and served are 256*256.
I think the tiles should be working however I am still getting an error that my tiles are out of range even after I checked to make sure that I did not swap the X and Y. One error is that MapCache is reporting tile y=189759 is not within 334028 to 334954.

Issue 2:
*Firefox is reporting that a cross-origin request is blocked.

Please let me know if you might know how I can fix these problems. For reference I the public server and configuration information is below.

Thank You!
