How to search by northing and easting values?

SanajyJadhav — Wed, 03 Aug 2011 10:19:46 GMT

Hi,

We want to develop one functionality in our application.User would enter northing/easting values and we have to locate these values on the map. Just like go to x-y in ArcMap.

I am not sure how to proceed with this.I cannot find any class in Silverlight API that would convert easting/northing values to lat-long.

Can anybody please help me out on this issue?I would really appreciate it.

Thanks-
Sanjay.

ArcGIS Server Supports projection. Here is a REST endpoint that can convert many different coordinate systems.
http://sampleserver3.arcgisonline.com/ArcGIS/rest/services/Geometry/GeometryServer/project

Reference documentation on how to use the REST endpoint:
http://sampleserver3.arcgisonline.com/ArcGIS/SDK/REST/index.html?project.html

List of projections that are supported(Well know ID):
Geographic Coordinate System
http://sampleserver3.arcgisonline.com/ArcGIS/SDK/REST/gcs.html
Projected Coordinate System
http://sampleserver3.arcgisonline.com/ArcGIS/SDK/REST/pcs.html

Example of Silverlight using the projection geometry service

Hope this helps!

Thanks Chris for the reply.

So, it seems I have to use Geometry service to re-project the point.Ok. I'll give a try.

Cheers,
Sanjay.
