    v203 v204  
    368368=== Old Printed Maps ===
    369369Old Printed Maps can be 'Rectified' to be overlaid on the base maps:
    370  * [wiki:BluePrintGISRectifier]
     370* [wiki:BluePrintGISRectifier]
    371371== !OpenStreetMap ==
    372 === Base Map ===
    373 We have out-of-the-box the ability to use !OpenStreetMap Tiles as base layer.
    374 
    375 This can include local OSM sites (OSM Taiwan is included as an example)
    376 
    377 === Vector Overlays ===
    378 Can have OSM Vectors displayed over the top of other Base Layers (e.g. Satellite Images)
    379 
    380  * [wiki:BluePrintGISOSMLayers]
    381 
    382 === Import ===
    383 We have an XSLT [http://eden.sahanafoundation.org/browser/static/formats/osm/import.xsl stylesheet] to import .osm files
    384 
    385 e.g for hospitals and clinics:
    386 {{{
    387 osmosis --read-xml country.osm --tf accept-nodes amenity=hospital,clinic --tf reject-ways --tf reject-relations --write-xml nodes.osm
    388 osmosis --read-xml country.osm --tf reject-relations --tf accept-ways amenity=hospital,clinic --used-node --write-xml ways.osm
    389 osmosis --rx nodes.osm --rx ways.osm --merge --wx country_hospitals.osm
    390 http://myhost.com/eden/hms/hospital/create.osm?filename=country_hospitals.osm
    391 }}}
    392 
    393 This needs more work to understand the admin hierarchy properly to be able to import Places.
    394 * http://wiki.openstreetmap.org/wiki/Map_Features#Places
    395 * http://wiki.openstreetmap.org/wiki/Placename_hierachies is_in tag
    396 
    397 Geofabrik have updated extracts daily for Pakistan:
    398 * http://download.geofabrik.de/osm/asia/pakistan.osm.bz2
    399 
    400 Otherwise pull a BBOX directly using Osmosis:
    401 * http://wiki.openstreetmap.org/wiki/Osmosis
    402 
    403 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:
    404 * http://dev.omniscale.net/imposm.parser/
    405 * [http://pbf.raggedred.net ParsePBF]
    406  * http://blog.lifeeth.in/2011/02/extract-pois-from-osm-pbf.html
    407 
    408 Ruby script to generate KML of recently-added locations by a group of users:
    409 * http://github.com/vertis/osm_export/tree/master
    410 
    411 Polygons:
    412 * http://help.openstreetmap.org/questions/8273/how-do-i-extract-the-polygon-of-an-administrative-boundary
    413 === Basemap for Garmin GPS ===
    414  * [wiki:UserGuidelinesGISDataOpenStreetMapGarmin]

    418376=== PostGIS functions ===
