[mapserver-users] mapcache question

[Lime, Steve D (MNIT)]

I would think reprojection of individual tiles into another set of tiles that would stitch back together without artifacts would be difficult. I thought MapCache did support native MapServer mode=map as a source which could useful if GDAL supports WMTS and you could create a corresponding MapServer layer.

Jukka,

According to the docs mapcache only support WMS as input.

" A source is a service mod-mapcache can query to obtain image data. This is typically a WMS server accessible by a URL. (There are currently no sources other than WMS implemented, though others may be added later if the need arises)"

If this is still true then your proposed chain will not work.

MapProxy will support a tiled source and I know TMS works  (not sure about WMTS) and handle the reprojection 

Regards

Hello,
I would like to put a mapcache to be in the middle, in the following chain:

1) original wmts service in local/national crs x   -->  2) mapcache wmts, reprojection to world-wide crs y (3857) -->  3) user interface (OpenLayers v2, Qgis), also in crs y

Mapcache was compiled, and is working a-ok with demo data. But I have trouble to configure mapcache to work as a part in the above chain. As planned, Mapcache should work as a WMTS client down towards target 1 and WMTS server up against target 3, ie. kind of a proxy with crs reprojection and basic auth. Anyway, does this make any sense at all, or is the draft totally irrational?

If the draft is reasonable, could you give some hints on how to proceed related to configuration with mapcache.xml?
