Ok, it seems there will be cases where the geometry satisfies the spatial
condition, but its component vertices of that line do not.
In that case, I guess you would iteratively break that line down into
smaller components (via linear interpolation?) and test the resulting
vertices. Eventually on
The spatial operations supported by a provider can be queried via the web tier
test pages:
http://localhost:8008/mapguide/mapagent/index.html
Click Feature as the category and GetCapabilities as the API and the list of
supported spatial operations is listed in the results.

By closest vertex are you referring to the actual start and end point of the
line? or the intersection of the circle and the line.
in attached image it sort of shows whats happening, user clicks where the
red x is, then we find all red lines in view. now I use the
geomerty.distance(point) to find
I am trying to compile Mapguide on RedHat EL 5.4, and am stuck on an error that
I have seen in a number of places. However, I am unable to find a solution that
works.
I'm new to Mapguide, so I may be making a newbie mistake, but I've searched
everywhere for an answer, and have spent a couple of
May be way off base Here...
If I understand correctly Mapguide Utilizes GEOS 3.0...Anyone?

If so couldn't You create one big geometry out of all roads on screen then
use the Distance DistanceOp function to find the nearest object?

This ClosestVertex of the ClosestFeature with the smallest distance should
the your point in question.
Also I'm a bit fuzzy with my spatial operators: WITHIN, TOUCHES, CONTAINS,
CROSSES (and possibly others) all seem to be legitimate operators for this
scenario.

Thanks for your help Jackie,
I've gone through your quick freehand code :) very well done
Perhaps a problem that the FDO provider "SDF" doesn't support Spatial
operator TOUCHES or WITHIN
after removing Touches I now get an error when adding entries to the matches
list.
If i expand the iterations
Thanks for the advice. I have been away from this since before the holiday.
Oddly enough, it now appears to be working just fine. I didn't change
anything, and to my knowledge, the server has not been rebooted since
immediately after installing the software. Oh well, all's well that ends wel
