I have exported a XML file from OSM and loaded it into global mapper for a vector map. My question is can you export from OSM one feature at a time so just the theme Roads, Rivers or Forests for example?

Any advice would be greatly appriciated

Many Thanks

OpenStreetMap data is not divided into different features by default. However, there are a number of ways of filtering the data based on the tags used.

For example, you can use XAPI to request data for the area that you are interested in containing only the tags that you want. You might find the front-end for the new service useful.

With an OSM file you can filter out selected data based on tags using Osmosis tag filters to create several OSM files corresponding to 'layers' in traditional GIS.

Another approach, which may or may not be suitable with Global Mapper is to load data into a PostGIS database using osm2pgsql. Some OpenSource GIS tools, such as Quantum GIS, allow this data to be queried so that specific subsets can be brought into the GIS for further manipulation and/or stored as shapefiles. Not all tags are retained using osm2pgsql, but the majority of widely used ones are immediately available. An example of this approach is discussed (my me) here.
