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
