Lat/Lon To State Plane

BernardNtiamoah — Wed, 06 Apr 2011 12:13:18 GMT

I am trying to write my own projection service that will project data from geographic coordinates to state plane. I've got some help from some geodesy websites but that's not enough for me. If you know any other resource, please let me know.

Thanks

Create a Geometry Service on your ArcGIS Server and use it's ProjectAsych method.

Here's a link to the ESRI sample - http://help.arcgis.com/en/webapi/silverlight/samples/start.htm#Project

Hi gilest, I am currently doing that but my boss asked me to create a class that we can use to actually project lat/lon to state plane....actual geodesy calculations...lol. I know about geometry service but he(my boss) wants me to write our own.

Thank you though

NOAA.gov has a web program and they also published the source code to it here.

http://www.ngs.noaa.gov/PC_PROD/SPCS83/

The source code is in fortran, but if you take it line by line, you should be able to translate it into your favorite programming language.

Good Luck
