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

Display usage information.
Dump segment list to stdout in plain text format.
Write segments to geometry file or database using OGR.
OGR format for writing out geometries.
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
