Different SRS in WMS/Basemap layers?

JörgPossin

Hi all,

I read a lot of threads in this forum and it seems that it is not possible to combine a ArcGIS Basemap and a WMS if the SRS don't match (http://forums.arcgis.com/threads/40478-How-to-add-WMS-in-flexviewer-basemaps?p=138193&viewfull=1#post138193 and http://forums.arcgis.com/threads/49500-WMS-skipgetcapabilities-bug-in-flexviewer-2.2?p=170743&viewfull=1#post170743. Is that right?

I want something like this:

srs= new SpatialReference(4326); //WGS84
map = new Map();
   
extent = new Extent(5.81429, 50.32778, 9.22005, 52.539, srs); 
map.extent = extent;

var wmslayers:ArrayList = new ArrayList();
wmslayers.addItem("Naturraeumliche_Haupteinheiten");
wmsmap = new com.esri.ags.layers.WMSLayer("http://www.wms.nrw.de/umwelt/linfos");
wmsmap.initialExtent =  extent;
wmsmap.spatialReference = srs;
wmsmap.visible = true;
wmsmap.visibleLayers = wmslayers;
map.addLayer(wmsmap);
      
streetmap = new ArcGISTiledMapServiceLayer("http://server.arcgisonline.com/ArcGIS/rest/services/World_Street_Map/MapServer");
streetmap.visible=true;
map.addLayer(streetmap);

The ESRI ArcGIS API can't reproject between different SRS?

regards,
Jörg

Hi - sorry for the delay, to answer your question, unfortunately...no you cannot use ArcGIS Server to reproject your existing WMS layer info to something else. There are methods in Server to allow reprojection of data but not for the scenario you are describing.

Thanks hgonzago. I could not find this information on the ESRI sites (or the web )
