Hi, I noticed a tool that I had never tried: http://gdal.org/ogrlineref.html
I did not understand the meaning of all the options so I just copied the example command but it failed for me. C:\temp\linref>ogrlineref -create -l line.shp -p references.shp -pm dist -o parts.shp -s 10 -progress Unsupported geometry type Line String for path What's wrong with Line String? This is how my source data (-l) looks: C:\temp\linref>ogrinfo line.shp INFO: Open of `line.shp' using driver `ESRI Shapefile' successful. 1: line (Line String) About the usage, should I understand that this utility cannot split lines or insert milestones on lines by a given distance but I must create the point file of milestone with some other tool and show that for ogrlineref with the -p parameter? For my trial I created such point file with OpenJUMP PLUS. -Jukka Rahkonen- _______________________________________________ gdal-dev mailing list gdal-dev@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/gdal-dev
