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:

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It is recommended to use the latest version from source rather than an out of date package: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
git clone https://github.com/openstreetmap/osm2pgsql
Optionally investgate updating this outdated patch (updated from original here): http://www.mail-archive.com/dev@openstreetmap.org/msg12768.html
#wget http://eden.sahanafoundation.org/raw-attachment/wiki/GIS/InstallationGuidelines/Linux/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)

2.0 is packaged for Wheezy, but we want the latest:

apt-get install -y libboost-dev libboost-filesystem-dev libboost-python-dev libboost-regex-dev libboost-system-dev libboost-thread-dev libpq-dev libfreetype6-dev libxml2-dev libjpeg-dev libpng-dev libtiff-dev libproj-dev
wget http://mapnik.s3.amazonaws.com/dist/v2.2.0/mapnik-v2.2.0.tar.bz2
tar jxvf mapnik-v2.2.0.tar.bz2
cd mapnik-v2.2.0
./configure
make
make test-local
make install

Download the OpenStreetMap extensions for Mapnik:

cd
svn export http://svn.openstreetmap.org/applications/rendering/mapnik

Download/decompress Coastlines:

cd
wget http://tile.openstreetmap.org/world_boundaries-spherical.tgz
wget http://tile.openstreetmap.org/processed_p.tar.bz2
wget http://tile.openstreetmap.org/shoreline_300.tar.bz2

wget http://www.naturalearthdata.com/http//www.naturalearthdata.com/download/110m/cultural/110m-admin-0-boundary-lines.zip
cd ~/mapnik
tar zxvf ~/world_boundaries-spherical.tgz
tar jxvf ~/processed_p.tar.bz2 -C world_boundaries
tar jxvf ~/shoreline_300.tar.bz2 -C world_boundaries
unzip ~/10m-populated-places.zip -d world_boundaries
unzip ~/110m-admin-0-boundary-lines.zip -d world_boundaries

Disable autovacuum:

vim /etc/postgresql/8.4/main/postgresql.conf
#autovacuum = on
/etc/init.d/postgresql restart

Download/Import area of interest, e.g.:

#wget http://downloads.cloudmade.com/north_america/haiti/haiti.osm.bz2
#su postgres
#osm2pgsql -s -d gis haiti.osm.bz2
wget http://labs.geofabrik.de/haiti/2010-11-24-14-43.osm.bz2
su postgres
osm2pgsql -s -d gis 2010-11-24-14-43.osm.bz2

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:

cd ~/mapnik
vim generate_tiles.py
render_tiles(bbox, mapfile, tile_dir, 0, 8, "World")
#minZoom = 10
#maxZoom = 16
#bbox = (-2, 50.0,1.0,52.0)
#render_tiles(bbox, mapfile, tile_dir, minZoom, maxZoom)
# Haiti
bbox = (-74.668, 17.884, -71.659, 20.232)
render_tiles(bbox, mapfile, tile_dir, 9, 17, "Haiti")
# Muenchen

Since we are non-commercial, we should be able to use the SRTM4.1 data from CGIAR, however the Shapefile production crashed when it reached 2Gb.
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

Serve Tiles

Tiles can simply be served by Apache:

vim /etc/apache2/sites-available/mysite
<VirtualHost *:80>
  ServerName mysite.org
  Alias /tiles     /var/www/tiles
  <LocationMatch "/tiles/">
    Order Allow,Deny
    Allow from all
  </LocationMatch>
</VirtualHost>
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:

Vector Overlays

Can have OSM Vectors displayed over the top of other Base Layers (e.g. Satellite Images)

BluePrint/GIS/OSMLayers

Import

We have an XSLT 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:

http://download.geofabrik.de/osm/asia/pakistan.osm.bz2

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:
