Installation of GIS Tools on Linux

Suggest these CLI tools for data manipulation:

GDAL

Simple functionality can be got from the Debian package:

apt-get install gdal-bin

Advanced functionality requires the latest version (install into /usr/local):

apt-get install -y g++ libproj-dev
cd /tmp
wget http://download.osgeo.org/gdal/1.10.1/gdal-1.10.1.tar.gz
tar zxvf gdal-1.10.1.tar.gz
cd gdal-1.10.1
./configure --with-python CPPFLAGS="-fPIC"
make
make install
cd ..
ldconfig

Python bindings (e.g. needed for Shapefile Layers and GADM importer) included in above version.

e.g. If you are serving GeoTIFFs larger than 2Gb, you should create an Image Pyramid:

mkdir pyramid
~/gdal-1.10.1/swig/python/scripts/gdal_retile.py -v -s_srs EPSG:4326 -r bilinear -levels 4 -ps 2048 2048 -co "TILED=YES" -co "COMPRESS=JPEG" -targetDir pyramid mygeotiff.tif

PostGIS

PostGIS adds Spatial storage to PostgreSQL (visit this page to configure PostgreSQL before returning here to continue with the GIS parts)

NB PostGIS in Debian Lenny is rather old - recommend using the version in Squeeze or Wheezy

Wheezy users:

apt-get install -y postgresql-9.1-postgis
su postgres
createuser -s -P gis

createdb -O gis -E UTF8 gis -T template0
psql -d gis -f /usr/share/postgresql/9.1/contrib/postgis-1.5/postgis.sql
psql -d gis -f /usr/share/postgresql/9.1/contrib/postgis-1.5/spatial_ref_sys.sql

Squeeze users:

apt-get install -y postgresql-8.4-postgis
su postgres
createuser -s -P gis

createdb -O gis gis
createlang plpgsql -d gis
psql -d gis -f /usr/share/postgresql/8.4/contrib/postgis-1.5/postgis.sql
psql -d gis -f /usr/share/postgresql/8.4/contrib/postgis-1.5/spatial_ref_sys.sql

Ubuntu users (Lucid/PostgreSQL 8.4/Post-GIS 1.4) - the paths are slightly different

psql -d gis -f /usr/share/postgresql/8.4/contrib/postgis.sql
psql -d gis -f /usr/share/postgresql/8.4/contrib/spatial_ref_sys.sql

Add Spherical Mercator projection (900913. See http://www.cadmaps.com/gisblog/?p=81 for 54004):

  • Not needed with PostGIS-1.5 :)
    psql gis
    INSERT into spatial_ref_sys (srid, auth_name, auth_srid, srtext, proj4text) values (900913 ,'EPSG',900913,'GEOGCS["WGS 84", DATUM["World Geodetic System 1984", SPHEROID["WGS 84", 6378137.0, 298.257223563,AUTHORITY["EPSG","7030"]], AUTHORITY["EPSG","6326"]],PRIMEM["Greenwich", 0.0, AUTHORITY["EPSG","8901"]], NIT["degree",0.017453292519943295], AXIS["Longitude", EAST], AXIS["Latitude", NORTH],AUTHORITY["EPSG","4326"]], PROJECTION["Mercator_1SP"],PARAMETER["semi_minor", 6378137.0], PARAMETER["latitude_of_origin",0.0], PARAMETER["central_meridian", 0.0], PARAMETER["scale_factor",1.0], PARAMETER["false_easting", 0.0], PARAMETER["false_northing", 0.0],UNIT["m", 1.0], AXIS["x", EAST], AXIS["y", NORTH],AUTHORITY["EPSG","900913"]] |','+proj=merc +a=6378137 +b=6378137 +lat_ts=0.0 +lon_0=0.0 +x_0=0.0 +y_0=0 +k=1.0 +units=m +nadgrids=@null +no_defs');
    

Using PostGIS in Sahana

Java

Update: As of version 2.0, a Java Runtime Environment (JRE) is sufficient to run GeoServer. GeoServer no longer requires a Java Development Kit (JDK). Also note, OpenJDK does not work optimally with GeoServer.

for Debian 7 Wheezy:

# Remove OpenJDK & dependent packages
apt-get remove openjdk-6-jre-lib
# Install a fake package to tell Debian that a valid Java is installed
wget http://babel.ls.fi.upm.es/~vpablos/others/packages/debian/oracle-java-pkg-for-debian_1.0.4_all.deb
dpkg -i oracle-java-pkg-for-debian_1.0.4_all.deb
# Download Sun Java via Browser (need to accept T&C)
# http://www.oracle.com/technetwork/java/javase/downloads/server-jre7-downloads-1931105.html
http://download.oracle.com/otn-pub/java/jdk/7u25-b15/server-jre-7u25-linux-x64.tar.gz
cd /usr/lib/jvm
tar zxvf /tmp/server-jre-7u25-linux-x64.gz
ln -s /usr/lib/jvm/jdk1.7.0_25 /usr/lib/jvm/java-sun
rm /usr/bin/java
ln -s /usr/lib/jvm/java-sun/bin/java /usr/bin/java
rm /usr/bin/javac
ln -s /usr/lib/jvm/java-sun/bin/javac /usr/bin/javac

vi /etc/environment
JAVA_HOME=/usr/lib/jvm/java-sun
export JAVA_HOME

or,

for ubuntu 10.x:

vim /etc/apt/sources.list
#uncomment partner repository
sudo apt-get update
sudo apt-get install sun-java6-jre

sudo emacs /etc/environment
JAVA_HOME=/usr/lib/jvm/java-6-sun
export JAVA_HOME

or,

for debian 6 Squeeze

vim /etc/apt/sources.list
# for sun-java packages in unstable
deb http://ftp.debian.org/debian/ unstable non-free
deb-src http://ftp.debian.org/debian/ unstable non-free

apt-get update
apt-get install sun-java6-jdk
vim /etc/profile
JAVA_HOME=/usr/lib/jvm/java-6-sun
export JAVA_HOME

The Sun installer will present a license in a curses form. Depending on your terminal emulator, arrow keys may not work for navigation. If not, try ^f and ^b to navigate to the <ok>, and enter to select. Then you'll be asked to accept (or not) the license -- again use ^f or ^b to move to <yes> and hit enter.

or:

  • Download the JDK & install it:
    cd /usr/local
    sh ~/jdk-6u21-linux-i586.bin
    ln -sf /usr/local/jdk1.6.0_21 /usr/local/java
    vim /etc/profile
    JAVA_HOME=/usr/local/java
    export JAVA_HOME
    

Install the JAI extensions (improves performance for GeoServer WMS), the downloads available are listed here

64-bit:

cd /usr/lib/jvm/java-sun
wget http://download.java.net/media/jai/builds/release/1_1_3/jai-1_1_3-lib-linux-amd64-jdk.bin
wget http://download.java.net/media/jai-imageio/builds/release/1.1/jai_imageio-1_1-lib-linux-amd64-jdk.bin

# accept license
rm jai-1_1_3-lib-linux-amd64-jdk.bin
rm jai_imageio-1_1-lib-linux-amd64-jdk.bin

If you installed JRE (sudo sh on Ubuntu)

cd /usr/lib/jvm/java-sun/jre
wget http://download.java.net/media/jai/builds/release/1_1_3/jai-1_1_3-lib-linux-amd64-jre.bin
sh jai-1_1_3-lib-linux-amd64-jre.bin 
#accept licence and replace [yes]

MapServer

OpenStreetMap

OpenStreetMap data can be stored in a PostGIS database & rendered using Mapnik.

To support Key/Value pairs:

apt-get install postgresql-contrib-8.4
su postgres
psql -d gis -f /usr/share/postgresql/8.4/contrib/hstore.sql

To support Planet diff files:

su postgres
psql gis < /usr/share/postgresql/8.4/contrib/_int.sql

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

0.7.1 is packaged for Squeeze:

apt-get install python-mapnik unzip

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/10m/cultural/10m-populated-places.zip
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

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:

Rails Port

This is needed to allow editing of the data using Potlatch, JOSM, etc

apt-get install imagemagick libmagick9-dev

Printing

For Printing TMS layers, need to compile the Trunk version of the MapFish Print Module & then serve the resultant .war with Tomcat:

  1. Ensure that JAVA_HOME points to a JDK.
  2. Download & build source:
    svn checkout http://www.mapfish.org/svn/mapfish/print/trunk/
    cd trunk
    ./gradlew build
    
  3. Configure Tomcat
    vim /etc/tomcat6/policy.d/04webapps.policy
    permission java.io.FilePermission "/var/lib/tomcat6/webapps/print-servlet-1.2-SNAPSHOT/WEB-INF/classes/logging.properties", "read";
    
    /etc/init.d/tomcat6 restart
    
    vim /etc/apache2/sites-available/print
    
    
    ln -s /etc/apache2/sites-available/print /etc/apache2/sites-enabled/print
    /etc/init.d/apache2 restart
    
  4. Copy the WAR file to your %WEBAPPS% directory:
    cp trunk/build/libs/print-servlet-1.2-SNAPSHOT.war /var/lib/tomcat6/webapps
    
  5. (re)Start Tomcat
  6. Configure the Map URL for Eden to:
  7. Configure %WEBAPPS%\print-servlet-1.2-SNAPSHOT\config.yaml: http://www.mapfish.org/doc/print/configuration.html

Printing can also be done within GeoServer:

The 2.0.x versiondidn't support TMS layers, like OpenStreetMap. @ToDo: Test this latest version.

wget http://gridlock.opengeo.org/geoserver/2.1.x/community-latest/geoserver-2.1-SNAPSHOT-printing-plugin.zip
cd /var/lib/tomcat6/webapps/geoserver/WEB-INF/lib
unzip ~/geoserver-2.1-SNAPSHOT-printing-plugin.zip
/etc/init.d/tomcat6 restart
#wget http://geoserver.org/download/attachments/20938936/printing-data-2.0.x.zip
#cd /usr/local/geoserver-2.0.2/data_dir
#unzip ~/printing-data-2.0.x.zip
#/usr/local/geoserver/bin/shutdown.sh
#/usr/local/geoserver/bin/startup.sh &
  • Configure by editing /var/gis/geoserver_data_dir/printing/config.yaml according to Documentation

Proxy / Cache

A Proxy can cache remote servers &/or do Reprojection or Combination of Layers

If just wanting to cache the WMS served by GeoServer, then it's probably best to use the integrated GeoWebCache:

Alternatives:

NB This can reveal issues such as the max-width limitation on ArcGIS when converting 4326 to 900913:
