Hey,
If you have a spatial index file along with the shp file it should be pretty
easy.
You can just use the locateRecords function of the SpatialIndex class.
For an example, take a look at the ShapeLayer.

Subject: [OpenMap Users] shapefile checking bounds
My problem is fairly complex but somewhat straightforward.
I have a shapefile of National Weather Service warnings and watches.
I want to be able to take the extents that the OpenMap is viewing (i.e. the
4 lat/lon corners) and check if any /shape/ in the shapefile intersects. Or
in other words is within their viewing area (or at least a piece of one)?
Is there any good way anyone knows of to do this?
Ben
