Hi Dan What you need to do could easily be accomplished with GDAL and GEOS (for example with Python) or GeoTools and JTS (with Java), but as far as I know you should write yourself a script for performing this action. I don't know it there may already be production ready scripts performing what you need with this technologies. Your only option here could be to use GRASS, but as far as I know you need to import your shapefile to the GRASS database, use a GRASS command (v.reclass [0]) and export back to shapefile the result, so it is not very direct. best regards P [0] http://grass.fbk.eu/gdp/html_grass64/v.reclass.html -- Paolo Corti Geospatial software developer web: http://www.paolocorti.net twitter: @paolo_corti _______________________________________________ Discuss mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/discuss
