No, puedes hacer uso de un mismo archivo .MAP pero definiendo diferentes secciones LAYER con nombres diferentes para que puedas encender o apagar el temático que desees presentar.

RE: [mapserver-users] about thematics maps
Not necessarily. By layer I'm guessing you mean data source? If so you can certainly have multiple MapServer layers that reference the same data source but style the data differently. You can also have a single MapServer layer that can be configured dynamically to style the data differently. For example, you might have a constant thematic presentation based on a percentage value (e.g. 0-10: green, 10-20:yellow, etc...) and then you use different attributes (e.g. % income above $50,000, % age 60, % residents with yellow beagles) against that classification. All sorts of possibilities depending on your data.

Hello Salas, I think there are 2 options for you: 1) use one .map file but change that one layer's parameters on-the-fly through your application, using mapscript (http://www.mapserver.org/mapscript/), such as PHPMapScript, or 2) have a separate .map file for each of your thematic maps. One trick I have used in the past for thematic maps is to use mapfile includes (see description and example in http://www.mapserver.org/mapfile/Include.html) for each thematic layer. The benefit is that the mapfiles are much easier to read/manage. -jeff -- Jeff McKenna MapServer Consulting and Training Services http://www.gatewaygeomatics.com/ ___ mapserver-users mailing list mapserver-users@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/mapserver-users
