= Installation of GIS Tools on Linux =

Suggest these CLI tools for data manipulation:
 * GDAL's ogr2ogr, etc
 * [http://mpa.itc.it/rs/srtm/srtm_generate_hdr.sh Convert SRTM to GeoTIFF]

== PostGIS ==
 * [http://postgis.refractions.net PostGIS] adds Spatial storage to [http://www.postgresql.org PostgreSQL]
(alternatively these can be installed as part of [http://opengeo.org/community/suite/download/ 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

== Printing ==
For Printing TMS layers, need to compile the Trunk version of the [http://www.mapfish.org/doc/print/ MapFish Print Module] & then serve the resultant .war with [http://tomcat.apache.org 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:
  * http://host.domain:8180/print-servlet-1.2-SNAPSHOT/pdf/
 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:
 * http://geoserver.org/display/GEOS/Printing+2.0+HOWTO
However this version doesn't yet support TMS layers, like !OpenStreetMap.

unzip ~/printing-data-2.0.x.zip

/usr/local/geoserver/bin/startup.sh &
}}}
   * Configure by editing {{{/usr/local/geoserver-2.0.2/data_dir/printing/config.yaml}}} according to [http://trac.mapfish.org/trac/mapfish/wiki/PrintModuleServer Documentation]
