+
+== Base Map ==
+We have out-of-the-box the ability to use !OpenStreetMap Tiles as base layer.
+
+This can include local OSM sites (OSM Taiwan is included as an example)
+
+== Vector Overlays ==
+Can have OSM Vectors displayed over the top of other Base Layers (e.g. Satellite Images)
+
+ * [wiki:BluePrintGISOSMLayers]
+
+== Import ==
+We have an XSLT [http://eden.sahanafoundation.org/browser/static/formats/osm/import.xsl stylesheet] to import .osm files
+
+e.g for hospitals and clinics:
+{{{
+osmosis --read-xml country.osm --tf accept-nodes amenity=hospital,clinic --tf reject-ways --tf reject-relations --write-xml nodes.osm
+osmosis --read-xml country.osm --tf reject-relations --tf accept-ways amenity=hospital,clinic --used-node --write-xml ways.osm
+osmosis --rx nodes.osm --rx ways.osm --merge --wx country_hospitals.osm
+http://myhost.com/eden/hms/hospital/create.osm?filename=country_hospitals.osm
+}}}
+
+This needs more work to understand the admin hierarchy properly to be able to import Places.

+
+Geofabrik have updated extracts daily for Pakistan:

+
+Otherwise pull a BBOX directly using Osmosis:
+* http://wiki.openstreetmap.org/wiki/Osmosis
+
+Osmosis requires Java. Python options for filtering based on tag, which would be more suitable for integration within Sahana, however we need to add Polygon filtering using Shapely:
