[OSM-dev] osm2pgsql, .o5m import interface

[marqqs at gmx.eu]

Hi Jon,

no, reading .o5m.gz (resp. .o5c.gz) is not supported at present.
You usually don't do zlib compression with .o5m files, users will rather use lzop if processing speed is important, or 7zip if a minimal file size is required.

However, the .o5m file format is usually chosen because of its speed, and this advantage would get lost if you compressed the data. Therefore you may expect input files to be uncompressed (an uncompressed .o5m file has nearly the same size as a conventional .osm.bz2 file).

Don't worry, there should be no additional dependencies.

I just uploaded the necessary files to http://m.m.i24.cc/o5m_osm2pgsql_20110702.zip

parse-o5m.c (new)
parse-o5m.h (new)
osm2pgsql.c (a few minor changes)
Makefile.am (added parse-o5m.c and parse-o5m.h)

Please consider the source as experimental. The import of a small test region (100x100 km) worked fine, but there sill might be some bugs...
