RES: [Mapserver-users] Dynamic creation of shapefiles ...

[Murilo Lacerda Yoshida]

  Thanks Lowell, but I have solved the problem... I had a logical
problem... I was adding a point with lat as X and long as Y... and in
the extent I was doing the opposite... I guess I saw there was something
wrong with the extent, but I forgot to change the points...
  Now it's working, thanks a lot!!

Try using shpinfo to verify that there are the same number of shapes as
there are dbf records.
The shpinfo output should also tell you what the extents of the
shapefile are.
