[Geomoose-users] TMS layers in GeoMoose 2.2

[Jim Klassen]

I haven't tried a TMS that isn't in the 3857 projection.  I wouldn't be surprised if this isn't easily supported before 2.6.  I know when I was trying out different TMS parameters in 2.4 that I needed to create a custom layer type to deal with it.  For more standard TMS layers, I used the "xyz" type in 2.4.

I would recommend you use WMS to access your MapCache tiles if you are using non-web-mercator projections in GeoMoose 2.2.  MapCache will still use any cached tiles to assemble the result.  GeoMoose 2.6 (along with the newer OpenLayers version) at least has the potential to make non-standard TMS configurations work from the mapbook.  (Although I suspect the code for the TMS map source will need to be extended… it will at least be possible to do this in a sane manner).

I haven't tried WMTS.  I suspect it misses the biggest reason of having tiles in the first place… the fact that they can be cached using standard HTTP caches and CDNs that aren't geo-spatially aware.  Tiles aren't so much for your server as they are for the network.  Also, make sure you have HTTP1.1 Keep-Alives active on your web servers.  Assuming that your data and map files are organized so that MapServer can operate efficiently, without Keep-Alives, the extra network overhead from the many requests for tiles will overwhelm any speedup from having everything cached.
