Reverse Geocode by latitude and longitude

MIkeColonna — Thu, 20 Sep 2012 14:36:49 GMT

Hello all,

I'm a newbie to ArcGIS

I been searching around the forum and got most of my questions answer without having to post one of my own until now.

I have the latitude and longitude and I need Reverse Geocode to find the state.

I don't need the MAP so I'm not sure if there is way to pass a function the latitude and longitude and get the candidate.address object?

any help would be great thanks.

Found the answer: had the lat-lon Reverse and the wrong SpatialReference below is the simple app if anyone else new runs into this problem...
