This is the command ogrlineref that can be run in the OnWorks free hosting provider using one of our multiple free online workstations such as Ubuntu Online, Fedora Online, Windows online emulator or MAC OS online emulator
PROGRAM:
NAME
ogrlineref - ogrlineref The 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
distances

DESCRIPTION
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 writed 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).
-lsrc_line_datasource_name:
The path to input linestring datasource (e.g. the road)
-lnlayer_name:
The layer name in datasource
-lffield_name:
The field name of uniq values to separate the input lines (e.g. the set of roads)
-psrc_repers_datasource_name:
The path to linear references points (e.g. the road mile-stones)
-pnlayer_name:
The layer name in datasource
-pmpos_field_name:
The field name of distances along path (e.g. mile-stones values)
-pffield_name:
The field name of uniq values to map input reference points to lines
-rsrc_parts_datasource_name:
The path to linear reference file
-rnlayer_name:
The layer name in datasource
-odst_datasource_name:
The path to output linear reference file (linestring datasource)
-onlayer_name:
The layer name in datasource
-offield_name:
The field name for storing the uniq values of input lines
-sstep:
The part size in linear units
-get_pos:
Return linear referenced position for input X, Y
-xlong:
Input X coordinate
-ylat:
Input Y coordinate
-get_coord:
Return point on path for input linear distance
-mposition:
The input linear distance
-get_subline:
Return the portion of the input path from and to input linear positions
-mbposition:
The input begin linear distance
-meposition:
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
