DESCRIPTION

22       The ogrlineref program can be used for:
23
24       • create linear reference file from input data
25
26       • return the "linear referenced" distance for the projection of the in‐
27         put coordinates (point) on the path
28
29       • return  the  coordinates (point) on the path according to the "linear
30         referenced" distance
31
32       • return the portion of the path according to the  "linear  referenced"
33         begin and end distances
34
35       The  ogrlineref  creates  a linear reference - a file containing a seg‐
36       ments of special length (e.g. 1 km in reference units) and get  coordi‐
37       nates,  linear  referenced  distances  or sublines (subpaths) from this
38       file.  The utility not required the M or Z values in geometry.  The re‐
39       sults can be stored in any OGR supported format.  Also some information
40       is written to the stdout.
41
42       --help-general
43              Show the usage.
44
45       -progress
46              Show progress.

49
50       -f <format_name>
51              Select an output format name. The default is to create a  shape‐
52              file.

EXAMPLE

130       This example would create a shapefile  (parts.shp)  containing  a  data
131       needed for linear referencing (1 km parts):
132
133          ogrlineref -create -l roads.shp -p references.shp -pm dist -o parts.shp -s 1000 -progress
