NAME¶
osmium-check-refs - check referential integrity of OSM file
SYNOPSIS¶
osmium check-refs [
OPTIONS]
OSM-DATA-FILE
DESCRIPTION¶
Ways in OSM files refer to OSM nodes; relations refer to nodes, ways, or other
relations. This command checks whether all objects
referenced in the
input file are also
present in the input file.
Referential integrity is often broken in extracts. This can lead to problems
with some uses of the OSM data. Use this command to make sure your data is
good.
If the option -r is not given, this command will only check if all nodes
referenced in ways are in the file, with the option, relations will also be
checked.
This command expects the input file to be ordered in the usual way: First nodes
in order of ID, then ways in order of ID, then relations in order of ID.
This command will only work for OSM data files, not OSM history files or change
files.
OPTIONS¶
- -i, --show-ids
- Print all missing IDs to STDOUT. If you don't give this option, only a
summary is shown.
- -r, --check-relations
- Also check referential integrity of relations. Without this option, only
nodes in ways are checked.
COMMON OPTIONS¶
- -h, --help
- Show usage help.
- -v, --verbose
- Set verbose mode. The program will output information about what it is
doing to stderr.
- --progress
- Show progress bar. Usually a progress bar is only displayed if STDERR is
detected to be a TTY. With this option a progress bar is always shown.
Note that a progress bar will never be shown when reading from STDIN or a
pipe.
- --no-progress
- Do not show progress bar. Usually a progress bar is displayed if STDERR is
detected to be a TTY. With this option the progress bar is suppressed.
Note that a progress bar will never be shown when reading from STDIN or a
pipe.
- -F, --input-format=FORMAT
- The format of the input file(s). Can be used to set the input format if it
can't be autodetected from the file name(s). This will set the format for
all input files, there is no way to set the format for some input files
only. See osmium-file-formats(5) or the libosmium manual for
details.
MEMORY USAGE¶
osmium check-refs will do the check in one pass through the input data.
It needs enough main memory to store all temporary data.
Largest memory need will be about 1 bit for each node ID, for a full planet
that's roughly 500 MB these days (Summer 2015). With the
-r,
--check-relations option memory use will be a bit bigger.
DIAGNOSTICS¶
osmium check-refs exits with exit code
- 0
- if all references are satisfied
- 1
- if there was an error processing the data or some references were not
satisfied, or
- 2
- if there was a problem with the command line arguments.
