DESCRIPTION

       The ogrlineref program 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
         distances

       The ogrlineref creates 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.

       --help-general
              Show the usage.

       -progress
              Show progress.

       -quiet Suppress all messages except errors and results.

       -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
              Create the linear reference file (linestring of parts).

       -l <src_line_datasource_name>
              The path to input linestring datasource (e.g. the road)

       -ln <layer_name>
              The layer name in datasource

       -lf <field_name>
              The  field  name  of  unique  values  to separate the input lines (e.g.  the set of
              roads).

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

       -pn <layer_name>
              The layer name in datasource

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

       -pf <field_name>
              The field name of unique values to map input reference points to lines.

       -r <src_parts_datasource_name>
              The path to linear reference file.

       -rn <layer_name>
              The layer name in datasource

       -o <dst_datasource_name>
              The path to output linear reference file (linestring datasource)

       -on <layer_name>
              The layer name in datasource

       -of <field_name>
              The field name for storing the unique values of input lines

       -s <step>
              The part size in linear units

       -get_pos
              Return linear referenced position for input X, Y

       -x <long>
              Input X coordinate

       -y <lat>
              Input Y coordinate

       -get_coord
              Return point on path for input linear distance

       -m <position>
              The input linear distance

       -get_subline
              Return the portion of the input path from and to input linear positions.

       -mb <position>
              The input begin linear distance

       -me <position>
              The input end linear distance

EXAMPLE

       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
