Hello, thanks for the Answer, 

I tried using botton-left but it’s the same behavior. 

Best regards

Andy

Sie erhalten nicht oft eine E-Mail von traviskirstine at gmail.com <mailto:traviskirstine at gmail.com> . Erfahren Sie, warum dies wichtig ist <https://aka.ms/LearnAboutSenderIdentification> 

My guess <origin>top-left</origin> is your issue, I believe the tms standard is for bottom-left

Hello everyone, 

I set up a mapcache layer for a customer of mine. 
The layer looks like this:

When requesting the layer via wmts or wms everything works fine. 
My customer requires TMS – when I request the tiles with tms the tiles are not at the right place.

Z0: At Z0 the tiles match:

At Z1 they are not at the same place:

And e.g. at Z6 it looks like this: 

https://user-images.githubusercontent.com/59861665/231165727-a638e7d8-8803-4c81-a2bd-7ff70ed04020.png <https://eur03.safelinks.protection.outlook.com/?url=https%3A%2F%2Fuser-images.githubusercontent.com%2F59861665%2F231165727-a638e7d8-8803-4c81-a2bd-7ff70ed04020.png&data=05%7C01%7Casteiner%40eurofunk.com%7Cbec421cd442c4b17a87f08db3b186bec%7C6d4fa94918de4214a28c3e8c7fa9c25b%7C0%7C0%7C638168748300394319%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C3000%7C%7C%7C&sdata=Cdu9ZTIog0K75%2BoabkexCREen5zIqWW%2Berxw3rcwBvM%3D&reserved=0> 

That’s the configuration for the GRID: 

  <grid name="WORLD">

      <metadata>

        <title>GoogleMapsCompatible</title>

        <WellKnownScaleSet>urn:ogc:def:wkss:OGC:1.0:GoogleMapsCompatible</WellKnownScaleSet>

      </metadata>

      <extent>-20037508.3427892480 -20037508.3427892480 20037508.3427892480 20037508.3427892480</extent>

      <srs>EPSG:3857</srs>

      <size>256 256</size>

      <srsalias>EPSG:900913</srsalias>

      <origin>top-left</origin>

      <resolutions>156543.03392800014 78271.51696399994 39135.75848200009 19567.87924099992 9783.93962049996 4891.96981024998 2445.98490512499 1222.992452562495 611.4962262813797 305.74811314055756 152.87405657041106 76.43702828507324 38.21851414253662 19.10925707126831 9.554628535634155 4.77731426794937 2.388657133974685 1.1943285668550503 0.5971642835598172</resolutions>

  </grid>

I also tried to use a EPSG:4326 with a extend -180 -180 180 180 but it’s the same result. 

The url I used looks like this: http://XX /mapcache/tms/1.0.0/ <http://XX%20/mapcache/tms/1.0.0/%3ctileset%3e@WORLD/%7bz%7d/%7bx%7d/%7by%7d.png> <tileset>@WORLD/{z}/{x}/{y}.png

Maybe someone has an idea why it doesn’t work. 

Thanks in advance. 

Best regards

Andy
