Issue with Custom WMS Server Tiles

Posted by Simon McIlroy on January 10, 2012 at 9:24am

I have been trying the WMS Map features in APM Mission Planner.

There appears to be an error in the tiling.

I have connected to my wms server which serves marine charting information.
APM connects and retrieves tiles, but there appears to be an issue with the arrangement of the tiles.
See the screen shot below.

Has anyone else got this working properly?

Cheers

    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.

    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.

    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)
