How can I check if a point belongs to a polygon? I want to create a custom identify tool with edit option. I am using C# and ArcMap 10.
My idea is to click on the polygon (building/park/etc) in ArcMap and if the cursor coordinates belongs to polygon, get its parameters from building_layer for further checking (number of building, street name).
You will want to create a ToolControl button that allows you to click on a map as opposed to a button which does something when you click on it. Then grab the point, create a spatialfilter and query your polygon layer, this returns a Feature object which you can return the various address components and populate some form that you created. The bold words are the key interfaces you need to go away and research. There are many examples in the Help and on the various forums.
