== 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)
=== Local Tile Server ===
If you need to run offline then you need to set up your own Tile Server:
* http://switch2osm.org/serving-tiles/
* http://switch2osm.org/serving-tiles/manually-building-a-tile-server-12-04/
* http://blog.gravitystorm.co.uk/2010/07/05/map-rendering-on-ec2/
* https://help.openstreetmap.org/questions/11949/server-spec-for-running-osm
* http://weait.com/content/build-your-own-openstreetmap-server
* http://weait.com/content/make-your-first-map
* http://dbsgeo.com/foss4g2010/pdf/osm-rendering-foss4g2010.pdf
!OpenStreetMap data can be stored in a PostGIS database & rendered using Mapnik.
To support !Key/Value pairs:
{{{
apt-get install postgresql-contrib-9.3
su postgres
psql -d gis -f /usr/share/postgresql/9.3/contrib/hstore.sql
}}}
To support Planet diff files:
{{{
su postgres
psql gis < /usr/share/postgresql/9.3/contrib/_int.sql
}}}
=== Osm2pgsql ===
* http://wiki.openstreetmap.org/wiki/Osm2pgsql
It is recommended to use the latest version from source rather than an out of date package:
{{{
apt-get install build-essential libxml2-dev libgeos-dev libpq-dev libbz2-dev proj autoconf subversion libtool
svn export http://svn.openstreetmap.org/applications/utils/export/osm2pgsql/
Optional (patch updated from original here): http://www.mail-archive.com/dev@openstreetmap.org/msg12768.html
#wget http://eden.sahanafoundation.org/raw-attachment/wiki/InstallationGuidelinesGISDataLinux/osm2pgsql_centroid.patch
cd osm2pgsql
#patch -p0 < ../osm2pgsql_centroid.patch
./autogen.sh
./configure
sed -i 's/-g -O2/-O2 -march=native -fomit-frame-pointer/' Makefile
make
make install
# Fix needed for SVN version 0.70.5
cp default.style /usr/local/share
}}}
=== Mapnik ===
* http://wiki.openstreetmap.org/wiki/Mapnik
* http://mike.teczno.com/notes/mapnik.html (Advanced Tips)
0.7.1 is packaged for Squeeze:
{{{
apt-get install python-mapnik unzip
}}}
Download the !OpenStreetMap extensions for Mapnik:
{{{

Disable autovacuum:
{{{
vim /etc/postgresql/8.4/main/postgresql.conf
#autovacuum = on
/etc/init.d/postgresql restart
}}}
Download/Import area of interest, e.g.:
{{{

Re-enable autovacuum:
{{{
vim /etc/postgresql/8.4/main/postgresql.conf
autovacuum = on
/etc/init.d/postgresql restart
}}}
Setup XML file:
{{{
cd ~/mapnik
./generate_xml.py --accept-none --dbname gis --symbols ./symbols/ --world_boundaries ./world_boundaries/

Render tiles:
{{{

Since we are non-commercial, we should be able to use the SRTM4.1 data from [http://srtm.csi.cgiar.org CGIAR], however the Shapefile production crashed when it reached 2Gb.[[BR]]
Example for Haiti:
{{{
cd ~/mapnik/srtm
wget http://srtm.csi.cgiar.org/SRT-ZIP/SRTM_V41/SRTM_Data_GeoTiff/srtm_22_09.zip
unzip srtm_22_09.zip
gdal_contour -i 10 -snodata 32767 -a height "srtm_22_09.tif" "srtm_22_09.shp"
su postgres
shp2pgsql -p -I -g way "srtm_22_09" contours | psql -q gis
shp2pgsql -a -g way "srtm_22_09" contours | psql -q gis
}}}
Configure Mapnik:
{{{
vim ~/mapnik/osm.xml
# Under line &layer-shapefiles;
&layer-contours;
vim ~/mapnik/inc/layer-contours.xml.inc

==== Hillshading ====
* http://wiki.openstreetmap.org/wiki/HikingBikingMaps#Hill_Shading
=== Serve Tiles ===
Tiles can simply be served by Apache:
{{{
vim /etc/apache2/sites-available/mysite
ServerName mysite.org
Alias /tiles /var/www/tiles
Order Allow,Deny
Allow from all
apache2ctl restart
}}}
=== WMS ===
In order to serve the OSM data via WMS then can use mod_mapnik_wms:
* http://wiki.openstreetmap.org/wiki/Mod_mapnik_wms
{{{
gpg --gen-key
apt-get install pbuilder debsigs apache2-prefork-dev libmapnik-dev libgd2-xpm-dev
svn export http://svn.openstreetmap.org/applications/utils/mod_mapnik_wms
cd mod_mapnik_wms
sh autogen.sh
vim debian/mapnik_wms.load
LoadFile /usr/lib/libmapnik.so.0.7
debuild
}}}
This data can then be converted by !GeoServer into a KML !SuperOverlay to display in Google Earth:
* http://geoserver.org/display/GEOS/GSIP+47+-+WMS+cascading
* http://docs.geoserver.org/stable/en/user/googleearth/tutorials/superoverlaysgwc.html
=== Rails Port ===
This is needed to allow editing of the data using Potlatch, JOSM, etc

== Vector Overlays ==
Can have OSM Vectors displayed over the top of other Base Layers (e.g. Satellite Images)
* [wiki:BluePrint/GIS/OSMLayers]
== 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:

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:
