Hello, 

 

i have another hint maybe. 

The source is a mapproxy layer where the source of the mapproxy layer has a 
GLOBAL_WEBMERCATOR grid --> EPSG:3857 and origin north-west (top-left).

I don’t know how to configure mapcache and mapproxy that the output of that 
layer gets a bottom-left origin since tms only supports bottom-left. 

So we know the issue is that we have different origins at source and target. 

Maybe you know how I should configure it. 

Thanks in advance.

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://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%7Cdf03d26da26b45637bd208db3b1db2cb%7C6d4fa94918de4214a28c3e8c7fa9c25b%7C0%7C0%7C638169639115429132%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C2000%7C%7C%7C&sdata=OYKHZx9vLqNQ17tQMu8QLrTfP%2BSFC4JxBJZWhKxXGFg%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

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

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

 

Thanks in advance. 

 

Best regards

Andy
