Is it possible to extract Roads and Trails vectors from SPOT Raster Tiff Image? Actually I have tried SPRING software to extract road vectors from this raster. Yes, It gives good result, But unfortunately it extracts road data only. It fails to extract trails. I have shared a sample data via Google Drive,FYI EPSG: 26913
Anyone had succeeded extracting low width trails/Roads? If yes, please guide me to achieve it.I want to extract the data as polyline or polygon data.(any Free software to do this task would be much helpful)
