IdentifyTask point buffer

SangamLama — Thu, 10 Mar 2011 16:24:01 GMT

Hi,

When I click on the map on my application, it carries out IdentifyTask and returns what layers were found on that coordinate. Now, there are hydrants on my map. When I click on a hydrant, the function finds the hydrant, but only about 10-15% of the time. I know it might be something to do with the way the pixels are set, so that even when it seems like I clicked on the top of the hydrant, it really isn't.

Is there a better way to increase the area the click covers, so that I click on the hydrant like, 100% of the times? 🙂
