[maplab-users] to show a point on the map

[Jeff McKenna]

Hello,

Yes you need to create a point layer in the mapfile for your new 
shapefile.  The maplab tutorial covers how to add a point layer through 
MapEdit (maplab-2.2.1\htdocs\tutorial\maplab_tutorial.html section 
"Adding Layer Objects with Vector Data").

If you want to see an example layer for a point shapefile open the 
tutorial mapfile in a text editor (maplab-2.2.1\tutorial\tutorial.map 
->"popplace" layer).

To avoid any projection issues, the easiest way is to make a new 
mapfile, set the EXTENT to your shapefile's extents, and add your point 
layer.

To get your shapefile's extent value you can use the ogrinfo utility, 
that comes with MS4W and FWTools (both available on maptools.org).

Good luck.
