overlays two Tiled Map Services with Different Spatial References

lasinh — Thu, 22 Dec 2016 04:32:18 GMT

i use Esri basemap World_Topo_Map (MapServer)

then overlay my Tiled Map Services; my Tiled Map Services display incorrect place.

How To overlays two Tiled Map Services with Different Spatial References in ArcGIS API for JavaScript?( two Services cached scale as same; Different Spatial References)??

my code:

La Sinh,

You Can Not use two tiled services that are not in the same WKID.

Thank repply, you have any approach for this problem? can use Dynamic map service overlay Esri basemap World_Topo_Map (MapServer)?

La Sinh,

Yes you can use ArcGISDynamicMapServiceLayer as that type layer will request ArcGIS Server to reproject the data to match the maps WKID.

About speed, ArcGISDynamicMapServiceLayer speed faster or run faster tiled servicesArcGISDynamic? MapServiceLayer has not load faster tiled services?

Tiles will always be faster
