CreepinJesus Posted April 10, 2015 Share Posted April 10, 2015 I'm looking for some help in creating an image for use as a raster in a GIS application.I have some land use survey maps from the 1903s and I need to have a raster of the areas of different land uses (which I can later polygonise, etc.). I'm trying to avoid having to draw all the polygons out manually, so I thought there may be a way to create these rasters from the original map scans.Attached are two files: 'Original' shows the style of the original maps, and 'Output' shows something along the lines of what I'm trying to achieve, only I need it more 'in focus' and using distinct colours only (maximum of 6, if possible, as there are 6 different classes on the original maps).Does anyone know if this can be done in Paint.net? I have access to Photoshop if there's something I can use in that.Thanks. Quote Link to comment Share on other sites More sharing options...
