OSMCOASTLINE_SEGMENTS(1) OSMCOASTLINE_SEGMENTS(1)

NAME

osmcoastline_segments - analyze OpenStreetMap 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
