Installation of GIS Tools on Linux

Suggest these CLI tools for data manipulation:

PostGIS

(alternatively these can be installed as part of OpenGeoSuite)

apt-get install postgresql-8.3-postgis
su postgres
createdb gis
createlang plpgsql gis
psql -d gis -f /usr/share/postgresql-8.3-postgis/lwpostgis.sql
psql -d gis -f /usr/share/postgresql-8.3-postgis/spatial_ref_sys.sql
  • Add Spherical Mercator projection (900913. See http://www.cadmaps.com/gisblog/?p=81 for 54004):
    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');
    
  • Allow remote access:
    passwd postgres
    
    vim /etc/postgresql/8.3/main/postgresql.conf
    listen_addresses = '*'
    
    vim /etc/postgresql/8.3/main/pg_hba.conf
    host    all         all         my.ip.add.ress/24     md5
    
    /etc/init.d/postgresql-8.3 restart
    
    vim /etc/iptables.rules
    -A INPUT -p tcp --dport 5432 -j ACCEPT
    
    reboot
    
    su postgres
    createuser -s -P gis
    

(Don't do remote access as 'postgres' - to do so means can't simply access psql via 'su postgres')

  • Adjust postgresql.conf for performance relative to resources available (http://wiki.postgresql.org/wiki/Tuning_Your_PostgreSQL_Server)
    vim /etc/sysctl.conf
    # Increase Shared Memory available for PostgreSQL
    # 512Mb
    kernel.shmmax = 279134208
    # 1024Mb (may need more)
    #kernel.shmmax = 536870912
    kernel.shmall = 2097152
    
    sysctl -w kernel.shmmax=58720256
    sysctl -w kernel.shmall=2097152
    
    vim /etc/postgresql/8.3/main/postgresql.conf
    
    # This default is probably ok
    # adjust upward _or_ add a connection pooling layer like pgpool if running out of connections for clients
    max_connections = 100
    
    # shared_buffers = 24MB
    # Ideal is if all frequently accessed indexes and table rows can fit in here - this is often unrealistic
    # setting too high relative to system resources can be detrimental to the system.
    # At the high end this should be no more than 1/4 to 1/3 the available memory (ie that which is not being used by the OS or other processes).
    # Values suggested are quite conservative, so you can push them up a bit if there are resources available for it
    # but absolutely no more than 1/3 available memory.
    # 512Mb system suggest starting at:
    shared_buffers = 56MB
    # 1024Mb system suggest starting at:
    #shared_buffers = 160MB
    
    # effective_cache_size = 128MB
    # 512Mb system suggest starting at:
    effective_cache_size = 256MB
    # 1024Mb system suggest starting at:
    #effective_cache_size = 512MB
    
    #work_mem = 1MB
    # This is a per sort setting, so setting this too high with a high number of max_connections can be bad.
    # If the database load turns out to have a lot of sorting and not a lot of separate connections, you should increase this
    # and drop the max_connections.
    # 512Mb system suggest starting at:
    work_mem = 2MB
    # 1024Mb system suggest starting at:
    #work_mem = 4MB
    
    # As you get more memory in the system, moving this up can be quite useful if you notice vacuum processes taking forever.
    maintenance_work_mem = 16MB
    
    /etc/init.d/postgresql-8.3 restart
    

Java

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

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
    

Apache Tomcat

Tomcat is the recommended way to deploy Java applications

  • Debian:
    apt-get install sun-java6-jdk tomcat5.5 libapache2-mod-jk
    a2enmod jk
    vim /etc/libapache2-mod-jk/workers.properties
    workers.java_home=/usr/lib/jvm/java-6-sun
    
    vim /etc/init.d/tomcat5.5
    TOMCAT5_SECURITY=no
    /etc/init.d/tomcat5.5 restart
    

WMS/WFS

GeoServer

(recommended)

apt-get install unzip
wget http://downloads.sourceforge.net/project/geoserver/GeoServer/2.0.2/geoserver-2.0.2-war.zip

cd /var/lib/tomcat5.5/webapps
unzip ~/geoserver-2.0.2-war.zip

/etc/init.d/tomcat5.5 restart

vim /etc/iptables.rules
-A INPUT -p tcp --dport 8180 -j ACCEPT

reboot

http://geo.host.domain:8180/geoserver

or

wget http://downloads.sourceforge.net/project/geoserver/GeoServer/2.0.2/geoserver-2.0.2-bin.zip
cd /usr/local
unzip ~/geoserver-2.0.2-bin.zip
ln -sf /usr/local/geoserver-2.0.2 /usr/local/geoserver

vim /etc/profile
GEOSERVER_HOME=/usr/local/geoserver
export GEOSERVER_HOME

vim /etc/rc.local
/usr/local/geoserver/bin/startup.sh &

vim /etc/iptables.rules
-A INPUT -p tcp --dport 8080 -j ACCEPT

reboot

http://geo.host.domain:8080/geoserver

Configure:

MapServer

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/tomcat5.5/policy.d/04webapps.policy
    permission java.io.FilePermission "/var/lib/tomcat5.5/webapps/print-servlet-1.2-SNAPSHOT/WEB-INF/classes/logging.properties", "read";
    
    /etc/init.d/tomcat5.5 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/tomcat5.5/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:

However this version doesn't yet support TMS layers, like OpenStreetMap.

wget http://geoserver.org/download/attachments/20938936/printing-data-2.0.x.zip
cd /usr/local/geoserver-2.0.2/webapps/geoserver/WEB-INF/lib
unzip ~/printing-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 /usr/local/geoserver-2.0.2/data_dir/printing/config.yaml according to Documentation
