<p class=MsoNormal><span style='color:#1F497D'>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.<o:p></o:p></span></p>

<p class=MsoNormal>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. <o:p></o:p></p>
