place a point in the map

[Fawcett, David]

If you don't want to place your data in ESRI shapefiles or a database, you can use a simple text file as the data source for a layer.  

If your Mapserver binary has been compiled with OGR support (quite likely), you can use a virtual data source.  Take a look at the Vector Data Access Reference http://ms.gis.umn.edu:8081/ms_plone/docs/reference/vector_data/VirtualSpatialData

If you search the list archives for OGR and VRT, you will most likely find some example map file layers.

Subject: [UMN_MAPSERVER-USERS] place a point in the map


Recently I managed to create my own map and placed a symbol in it from a
database.

Now I need to place several points in the map. My database contains gps
coordinates like this:

4216 9669 259

Latitude: 42º 16'N
Longitude: 258ºE

I translated this gps coordinates to UTM coordinates to obtain:

Zone: 14
Easting: 252608
Norting: 4683531

I need to show this point in the map.

Someone could explain my how to do it? Thank you.

My present .map file is:
