osmcoastline_segments - analyze OpenStreetMap coastline changes from segment files
osmcoastline_segments [OPTIONS] SEGMENT-FILE1 SEGMENT-FILE2
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.
osmcoastline_segments exits with exit code
- if the segment files are the same
- if the segment files are different
- if there was a fatal error when running the program
- if there was a problem with the command line arguments.
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
