       ogrlinerefThe utility can be used for:

       · create linear reference file from input data

       · return the 'linear referenced' distance for the projection of the input coordinates
         (point) on the path

       · return the coordinates (point) on the path according to the 'linear referenced' distance

       · return the portion of the path according to the 'linear referenced' begin and end

       The ogrlineref program can be used to create a linear reference - a file containing a
       segments of special length (e.g. 1 km in reference units) and get coordinates, linear
       referenced distances or sublines (subpaths) from this file. The utility not required the M
       or Z values in geometry. The results can be stored in any OGR supported format. Also some
       information is written to the stdout.

       -f format_name:
           Select an output format name. The default is to create a shapefile.

       -dsco NAME=VALUE:
           Dataset creation option (format specific)

       -lco NAME=VALUE:
           Layer creation option (format specific)

           Create the linear reference file (linestring of parts).

           The path to input linestring datasource (e.g. the road)

           The layer name in datasource

           The field name of unique values to separate the input lines (e.g. the set of roads)

           The path to linear references points (e.g. the road mile-stones)

           The layer name in datasource

           The field name of distances along path (e.g. mile-stones values)

           The field name of unique values to map input reference points to lines

           The path to linear reference file

           The layer name in datasource

           The path to output linear reference file (linestring datasource)

           The layer name in datasource

           The field name for storing the unique values of input lines

           The part size in linear units

           Return linear referenced position for input X, Y

           Input X coordinate

           Input Y coordinate

           Return point on path for input linear distance

           The input linear distance

           Return the portion of the input path from and to input linear positions

           The input begin linear distance

           The input end linear distance


       This example would create a shapefile (parts.shp) containing a data needed for linear
       referencing (1 km parts):

       % ogrlineref -create -l roads.shp -p references.shp -pm dist -o parts.shp -s 1000 -progress
