OSM polygons extractor

Memory efficient Open Street Map (OSM) data converter to shp files. It may be used to extract polygon layers that exists in OSM database but are not extracted other way.

Requirements

• Python 2.7 (should work with earlier versions also)
• pyshp 1.2.0

Usage

usage: osmpolygons [-h] [--filter FILTER] [--include-tags META_KEYS]
                   [--no-cache] [--out OUT]
                   [input]

positional arguments:
  input

optional arguments:
  -h, --help            show this help message and exit
  --filter FILTER, -f FILTER
                        comma separated k=v pairs of relation tag filters
  --include-tags META_KEYS, -i META_KEYS
                        comma separated list of tag names to be extracted as
                        meta data
  --no-cache            disable partial results caches
  --out OUT, -o OUT     output file name (without extension)

Features

None of available tools I've seen does extract filtered polygons data from OSM. In Poland there is layer of powiats (administrative unit), that is not extracted in accessible datasets in shp format.

You may set different set of filters to grab any polygons layer you want

TODO

• Add osm pbf format handling (it's faster to process this than xml)
• Add optional dumps to json
• Add optional dumps to simple xml
• Add optional dumps to pickled tuples (metadatadict, [polylines])
