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
