Ubuntu, Gpsdrive, Mapnik, Postgress, Postgis, Openstreetmap
HOWTO
Copyright R K Scanlon June 2008
Version: 0.1
Date: 04 June 2008
Introduction
This howto will provide you with the steps needed to install gpsdrive with mapnik and Openstreetmap data. You will then have the capability to generate the map in gpsdrive on the fly. It is necessary to follow all steps in sequence to get it working correctly.
Conventions used in this document
Command line prompts:
$> user prompt
#> root prompt (su)
There are 9 sections to this how to:
1. Install Ubuntu
2. Setup gpsd
3. Setup PostgreSQL
4. Setup Postgis
5. Install osm2pgsl
6. Install Mapnik
7. Install Gpsdrive
8. Getting it all running together
9. Test Gpsdrive
Assumptions
I am using Ubuntu 8.04 you may elect to use another linux distribution. However I can not guarantee that this process will work on any other distribution. Some of the steps may be redundant for your distro but if you have problems then these may be a place to start.
I also assume you know how to use synaptic or apt-get in Ubuntu. If using another distro then you may have another package installer.
This is a clean install. If you already have your linux distribution in place then start from 1.3
I also created a directory /usr/src/gpsdrive to place all downloaded software to. So when you see download a file etc this is where it is downloaded to.
Likewise when unpacking a zip or tar file this is where it is done.
Whereever you see username in this document it means the user that will be running gpsdrive. this is usually your username.
Where instructed to change to root (su) or sudo then you need to enter the root password when prompted.
Software
Ubuntu 8.04
Postgres 8.3.1
Postgis 1.3.1
Mapnik 0.5.1
Gpsdrive from svn
gpsd
BEFORE YOU START.
This is a relative easy setup but at any point along the way if you get errors find out why and correct them before proceding further. If left uncorrected then you will not have everything working correctly at the end and will end up with a bigger mess to correct.
Steps
1. Install Ubuntu 8.04, other required libraries and perl modules
1.1 Use your preferred medium to install Ubuntu from. I have done install from both CD and USB Pen drive.
1.2 After installation has completed and you have a normal desktop login do a complete update.
1.3 Then install the following packages via synaptic or apt-get (these will be the current updated packages):
Package Required for Must have/optional
Postgres Postgres, OpenStreetMap must have
Python-pgsql Postgres, Mapnik, Gpsdrive(scripts) must have
Postgis Mapnik, Openstreetmap must have
Cmake Gpsdrive(build) must have
Gpsd Gpsdrive must have

libgda3-dev gpsdrive must have
libgda3-odbc gpsdrive must have
libgda3-postgres gpsdrive must have
libgda3-sqlite gpsdrive must have
gettext gpsdrive must have
subversion all must have
cpan gpsdrive (scripts) must have to install some extra perl modules
NOTE: Many of these will install dependencies as you go and I always find synaptic the best for this.
NOTE: Some of these may already be installed.
1.4 As root using CPAN install the following perl modules:
$> su
#> cpan
cpan> install DBI
cpan> install DBD::Pg
cpan> install DBD::SQLite
cpan> quit
#> exit
NOTE: If you have not used cpan before it will need to be configured. Just follow the prompts through when you first run it. All the defaults work fine.
NOTE: You may have to use "force install DBI" for the first package.
1.5 Create working directory for downloads etc.
$> sudo mkdir /usr/src/gpsdrive
$> sudo chown username.username /usr/src/gpsdrive
1.6 Download the following:
1.6.1 openstreetmap icons as debian packages from:
$> cd /usr/src/gpsdrive
$> wget
http://www.gpsdrive.de/debian/pool/main/openstreetmap-map-icons_7698_all.deb
NOTE: This is all of the icons if you only want some then the other files are there as well
NOTE: It should be possible to add this as a repositry to synaptic and update automatically
1.6.2 Install openstreetmap icons:
$> sudo dpkg -i openstreetmap-map-icons_7698_all.deb
or
$> su
#> dpkg -i openstreetmap-map-icons_7698_all.deb
1.6.3 World boundaries (51MB) and coastlines (~200MB):
$> wget
http://tile.openstreetmap.org/world_boundaries-spherical.tgz
$> wget
http://hypercube.telascience.org/~kleptog/processed_p.zip
$> tar -zxvf world_boundaries-spherical.tgz
$> unzip processed_p.zip
$> cp coastlines/* world_boundaries/
$> rmdir coastlines
This completes the installation of all the necessary libraries etc.
2. Setup gpsd
NOTE: This should be setup automatically so really just need to test if it's working correctly and there is really no point in going any further without getting this working.
NOTE: You need your gps for this.
2.1 Plug your gps in (I use a usb gps mouse).
2.2 Run:
&> gpspipe -r
This should produce a lot of nmea sentences which indicates your gps and gpsd is working correctly.
<ctrl>-C to exit.
NOTE: If you want to use gpsdrive with gps input do not proceed beyond here until you have this working.
3. Setup PostgreSQL
3.1 Create Database
You need to be authenticated as the PostgreSQL super user in order to execute many of the commands below. You can not login as this user. Instead as root enter:
$> su
#> su - postgres
$> <commands...>
As the postgres user run the following to create the database:
NOTE: Replace username with the user that will be using mapnik.
$> createuser username
$> createdb -E UTF8 -O username gis
$> createlang plpgsql gis
4. Setup PostGIS
4.1 As the postgresql super user:
NOTE: Replace username with the user that will be using mapnik.
$> psql -d gis -f /usr/share/postgresql-8.3-postgis/lwpostgis.sql
$> echo "ALTER TABLE geometry_columns OWNER TO username; ALTER TABLE spatial_ref_sys OWNER TO username;" | psql -d gis
$> exit
#> exit
5. Install osm2pgsql and the osm data
5.1 Using svn get osm2pgsql from:
$> cd /usr/src/gpsdrive
$> svn co
http://svn.openstreetmap.org/applications/utils/export/osm2pgsql/
5.2 Compile and install
$> cd /usr/src/gpsdrive/osm2pgsql
$> make
5.3 Download osm data
NOTE Before downloading the whole of the world data (>3GB) consider how much of this you really need. I downloaded only the data for my country as at this time I have no need for other places.
$> cd /usr/src/gpsdrive
For the whole world
$> wget
http://planet.openstreetmap.org/planet-latest.osm.bz2
For extracts see:
http://wiki.openstreetmap.org/index.php/Planet.osm#Extracts
5.4 Put the osm data into the database
$> cd /usr/src/gpsdrive/osm2pgsql
$> ./osm2pgsql -m -d gis ../planet-latest.osm.bz2
or
$> ./osm2pgsql -m -d gis ../your_downloaded_data_file.osm
or you can limit the data by using a bounding box
$> ./osm2pgsql --bbox minlon,minlat,maxlon,maxlat -m -d gis your_down_loaded_data_file.osm
minlat = minimum latitude
minlon = minimum longitude
maxlat = maximum latitude
maxlon = maximum longitude
Negative for latitude south and longitude west.
This took about 30 minutes for my country and I understand that for the world it takes several days.
See
http://wiki.openstreetmap.org/index.php/Mapnik#Tuning_the_database
and
http://wiki.openstreetmap.org/index.php/Mapnik#Loading_data
if you intend loading the whole world and/or encounter problems with loading the data.
This is done at this stage rather than using the script ("mapnik-osm-updater.sh") provided by gpsdrive as it gives you a chance to correct any possible errors early in the stage.
6. Install mapnik
6.1 Download mapnik from:
$> cd /usr/src/gpsdrive
$> wget
http://prdownload.berlios.de/mapnik/mapnik_src-0.5.1.tar.gz
6.2 Unpack mapnik, compile and install
$> tar -zxvf mapnik_src-0.5.1.tar.gz
$> cd mapnik-0.5.1/
$> python scons/scons.py PGSQL_INCLUDES=/usr/include/postgresql PROJ_INCLUDES=/usr/include PROJ_LIBS=/usr/lib XMLPARSER=libxml2
$> su
#> python scons/scons.py install PGSQL_INCLUDES=/usr/include/postgresql PROJ_INCLUDES=/usr/include PROJ_LIBS=/usr/lib XMLPARSER=libxml2
#> exit
6.3 Update /etc/ld.so.conf
Mapnik is installed in /usr/local/lib so you need to add that to /etc/ld.so.conf and run ldconfig.
$> su
#> echo "/usr/local/lib" >> /etc/ld.so.conf
#> ldconfig
#> exit
6.4 Move world boundaries/coastlines to mapnik directory
$> su
#> cd /usr/src/gpsdrive
#> cp -a world_boundaries /usr/local/share/mapnik
#> exit
6.5 Check Mapnik is working (optional)
This check is just to make sure that mapnik will render correctly from the data you have entered and is not necessary for gpsdrive to run. However it does provide you with a check that all is well upto this point.
6.4.1 Download scripts
$> cd /usr/src/gpsdrive
$> svn checkout
http://svn.openstreetmap.org/applications/rendering/mapnik
$> cd mapnik
6.4.2 Edit set-mapnik-dev
Edit the "set-mapnik-env" script to fit your local file names etc. All the settings are documented inside this script.
6.4.3 Creat osm.xml
Create the osm.xml file from osm-template.xml:
$> source ./set-mapnik-env
$> ./customize-mapnik-map >$MAPNIK_MAP_FILE
6.4.4 Edit generate_(tiles|image).py
Set a bounding box and zoom levels in generate_(tiles|image).py
$> ./generate_image.py
This produces one image of the bounding box you set and is an ideal way to check that everything to this point is working correctly.
or
$> ./generate_tiles.py
WARNING: This can take a long time to run and I do not recommend using it unless you need the tiles generated.
7. Install gpsdrive
7.1 Using svn get gpsdrive from:
$> cd /usr/src/gpsdrive
$> svn co
http://svn.gpsdrive.cc/gpsdrive/trunk gpsdrive-svn
7.2 Compile and install
$> cd gpsdrive-svn/build
$> ./build_make.sh
$> make
$> su
#> make install
#> exit
8. Getting it all running together
8.1 way.txt
$> touch ~/.gpsdrive/way.txt
8.2 Some symlinks and a directory to create
$> su
#> mkdir -p /usr/lib/mapnik/0.5
#> ln -s /usr/share/icons/map-icons/ /usr/local/share/icons
#> ln -s /usr/local/lib/mapnik/* /usr/lib/mapnik/0.5
$> exit
8.3 A script to run
$> cd /usr/src/gpsdrive/gpsdrive-svn
$> scripts/gpsdrive-update-mapnik-poitypes.pl
9 Test gpsdrive
9.1 Run from a terminal to check infomation sent to standard output.
$> gpsdrive
Anything other then the following may indicate incorrect operation.
DB: Using waypoints from local user file.
DB: Using waypoints from OpenStreetMap database.
Read 576 POI-Types from geoinfo.db
You should be able to select mapnik mode from Map Control. Assuming you have added the osm data then the map should be dynamically generated.
That's it you should now have a working gpsdrive/mapnik/openstreetmap setup.

FAQ
Q: How can I change the colours used by/with mapnik?
A: The colors for mapnik are set in the file ~/.gpsdrive/osm.xml which is created from /usr/share/gpsdrive/osm-template.xml on first run.
Q: When trying to access the database for poi's it keeps giving an error. I've narrowed this down to the fact there is no column poi in the table planet_osm_points. What should have put this column into the database table?
A: When GpsDrive is compiled with mapnik support, and the postgis database for mapnik is available, GpsDrive can use the Points of Interest stored there. Normally the database should be filled with the script "mapnik-osm-updater.sh", which will also create the 'poi' column necessary to use this feature. However the column 'poi' can also be created by using "gpsdrive-update-mapnik-poitypes.pl" at any time.
Q: How can I access all my mysql poi's from previous gpsdrive installation?
A: As of version 2.10pre5 GpsDrive stores its waypoints in an sqlite data-base. the mysql database used before is not necessary anymore. To get your waypoints from that mysql database to the new structure, you can export your data to a GPX file with 'poi-manager_mysql.pl -e -f FILE.GPX', which can then be imported with 'poi-import.pl -f FILE.GPX'. Take care, the import script just throws the waypoints into the database without any dupe checking!
Q: Are the POI in the postgres osm database or somewhere else?
A: There are two databases used for storing points:
All user created data and temporary points are stored in an sqlite file in the users home directory (~/.gpsdrive/waypoints.db), which will be created, if it's not existing there.
If mapnik is available, the OpenstreetMap points stored in the postgis database can also be used (Access is readonly!). This is also possible, when the displayed map is not rendered from the mapnik database (Mapnik mode off).
Q: How is the script gpsfetchmap.pl related to mapnik?
A: With this script, you can download bitmap images to use as maps. If mapnik mode is enabled, the maps to display are rendered live directly from the postgis database on your system. You don't have to download anything with gpsfetchmap.pl to use this feature. Please have a look at mapnik-osm-updater.sh, to see how to create this database and fill it with data from the OpenStreetMap project.
Q: The poi's are showing but the icons used are incorrect or missing.
A: Run gpsdrive-update-mapnik-poitypes.pl to update the poi's in the PostgreSQL database and the icons will then render correctly with the currently selected theme.
Q: On startup of gpsdrive I get "Cannot init mapnik. Mapnik support DISABLED: Could not create datasource. No plugin found for type 'shape' in layer 'world-1'". How do I fix this?
A: See section 8.2 above.
