[Mapserver-users] Plotting Multiple Lat/Long points and setting extents

[Stephen Woodbridge]

Lindsay,

This is a virtual data source that has been discussed many times in the 
archive and I think there may be an example on the wiki. Briefly, you 
need to calculate the bounding box of the points or set the default. You 
might want to define a border distance like 1-2% of the extents so the 
point on the edges are more visible. Then you draw (and label? them) 
using mapscript and your done.

Here is one example of a virtual data source, it may not be the best one 
for your needs:

Here is a php Mapscript page:
