Hi Rich,
Not sure if this is what you mean, but could GeoExt (http://geoext.org/)
be something for you?

Hi Rich, you can do this with the CGI or MapScript and it's quite easy with
OpenLayers. All versions support queries using polygons and version 5.6 takes a
WKT representation. Here's an example url:

Thanks for the feedback Charlton, I appreciate it. In black and white you can
imagine black water and white land or vice versa. Might also lose the map the
map altogether and just go with the cells/folds...

Hello List,
I want to be able to draw a circle dynamically using PHP MapScript. The
circle is defined by the coordinates of the centre and the radius in
kilometers. I realize that the circle is a polygon and I should probably
calculate all points. What is the best way to do it?
I would really
Totally off the cuff
$shape = ms_shapeObjFromWKT('POINT('+$x+' '+$y+')');
$shape = $shape->buffer($radius);

You might try a more recent version. Either 5.4.2 or 5.6 to see if the bug has
been fixed. I don't recall off the top of my head...
Using metatiles (that is, a tile rendered intentionally large and then clipped)
is one way around problems like this and tiling tools like TileCache support
that
In another approach, I believe MapServer wants you to define a bounding box for
the circle by creating a line shape with the first point at the UL coordinate
of that box and the second coordinate at the LR coordinate of the box. So you'd
offset your center point .5 KM to create those points. You
After mulling this over I think I'm wrong. Conceptually it's correct but the
points represent the center and a point on the circle I think. I'll post a
stand-alone example later tonite...

I use the javascript libraries that come with the mapserv demo to do "red
lining" on mapserv maps to create polygons which can then be used in a
postgis database search.
The libraries I use are cbe, mapserv, dbox, utils and wz_jsgraphics.
