yes Simon,

Iam using custom wms feature and prefetching with perfect results, its even better than G.M. or ArcGIS beacase APMplanner dosent build pyramids every time i pan the map.  

plz check : a. Your service is provided for WGS84?

                 b. try zoom to your area of interest, some times wms servers freak out when they project the hole think.(its an anti-rip method)

Hi James,

Good to know that it should work! That means it's my end and I can probably fix it :)

I think I've tied it down to the Geodesy (SRS) that my server is using.
My server is setup to use EPSG:4326

Do you know what SRS APMplanner is expecting, is it just basic WGS84 Lat Long.

An EPSG code would be terrific if you know it!

Cheers

Ok, so now I'm lost!

I tried searching the source code to find out what coordinate system APMplanner was wanting the WMS data in, and I can't find any reference of EPSG or WMS or anything remotely related to maps, such as OpenStreetMap.

My knowledge of coding is basic (A-level computing) but surely it must be somewhere?!

Can someone help me out with what I'm missing?

My WMS server works fine in Openlayers and Google Earth etc.

my guess is the source you are pulling from is not returning wgs84 images. as the planner requests box's based on lat long coords.

Having looked at this further, I think it's actually a tile size issue rather than a geodesy problem.

Can anyone tell me what size tiles the APM uses, my server currently deals up 256 x 256 and 1024 x 1024 size tiles.
