NAME¶
osmcoastline_segments - analyze coastline changes from segment files
SYNOPSIS¶
osmcoastline_segments [
OPTIONS]
SEGMENT-FILE1
SEGMENT-FILE2
DESCRIPTION¶
The
osmcoastline program can write out all segments of the coastline into
a file (when started with the
-S, --write-segments=FILE option).
This program can be used to compare two of those segment files in various ways
to detect coastline changes between different runs of the
osmcoastline
program.
OPTIONS¶
- -h, --help
- Display usage information.
- -d, --dump
- Dump segment list to stdout in plain text format.
- -g, --geom=FILENAME
- Write segments to geometry file or database using OGR.
- -f, --format=FORMAT
- OGR format for writing out geometries.
- -V, --version
- Display program version and license information.
DIAGNOSTICS¶
osmcoastline_segments exits with exit code
- 0
- if the segment files are the same
- 1
- if the segment files are different
- 3
- if there was a fatal error when running the program
- 4
- if there was a problem with the command line arguments.
EXAMPLES¶
Just return 0 or 1 depending on whether the segments are the same in both files:
-
osmcoastline_segments old.segments new.segments
Dump the list of removed and added segments to stdout:
-
osmcoastline_segments --dump old.segments new.segments
Create a shapefile with the differences:
-
osmcoastline_segments --geom=diff.shp old.segments new.segments
