[mapguide-users] RE: Spatial Query

[Dave Wilson]

You could do a spatial query using a circle in a loop continually increasing the radius each time until you get a result. Setting the initial radius and the increments of the circle probably depends on the coordinate system of the data although this is similar to the logic in the selection for a click select in the AJAX Viewer so you could start with that.

What is the best approach to performing a spatial query as such that a road segment closest to a point is selected?  Any examples out there?  Not sure if OpenLayers or Mapguide Api would be best, but appreciate any suggestions.

Thanks!

Brian
