Geotrek, a Natural Park Manager

• Ubuntu Server 12.04 Precise Pangolin (http://releases.ubuntu.com/12.04/)

A first estimation on system resources is :

• 1 Go RAM
• 10 Go disk space

Once the OS is installed (basic installation, with OpenSSH server), copy and extract the source archive.

Go into the extracted directory, just follow the installation process :

./install.sh

You will mainly be prompt for editing the base configuration file (settings.ini), using Vim (Finish with 'Esc' then ':wq' to save and quit).

To make sure the application runs well after a reboot, try now : reboot. And access the http://yourserver/.

See information below for configuration and loading initial demonstration data.

Keep previous versions in separate folders (recommended).

First, copy your old configuration and uploaded files to your new folder.

# Configuration files
mkdir -p etc/
cp ../previous-version/etc/settings.ini etc/
# Uploaded files
mkdir -p var/
cp -R ../previous-version/var/tiles var/tiles
cp -R ../previous-version/var/media var/media

Shutdown previous running version, and run install :

# Shutdown previous version
../previous-version/bin/supervisorctl stop all
sudo service supervisor stop

# Re-run install
./install.sh

# Reload configuration
sudo service supervisor restart

Or instead, if you prefer, you can overwrite the source code and run ./install.sh.

• Use symlinks for uploaded files and cached tiles to avoid duplicating them on disk:

mv var/tiles ~/tiles
ln -s ~/tiles `pwd`/var/tiles

mv var/media ~/media
ln -s ~/media `pwd`/var/media

• Speed-up upgrades by caching downloads :

mkdir ~/downloads
mkdir  ~/.buildout

Create /home/sentiers/.buildout/default.cfg with :

[buildout]
download-cache = /home/sentiers/downloads

• WMS (scan + ortho)
• Projection
• Bounding box in native projection

• Only LineString geometries
• Simple geometries
• Not overlapping

If possible :

• Connex graph
• Name column
• Data source

Formats: Shapefile or pure SQL dump SQL (CREATE TABLE + INSERT)

• Cities polygons (Shapefile or SQL, simple and valid Multi-Polygons)
• Districts (Shapefile ou SQL, simple and valid Multi-Polygons)
• Restricted Areas (Shapefile ou SQL, simple and valid Multi-Polygons)

• Languages list
• Structures list (and default one)

bin/django loaddem <PATH>/w001001.adf

note

This command makes use of GDAL and raster2pgsql internally. It therefore supports all GDAL raster input formats. You can list these formats with the command raster2pgsql -G.

Load basic data :

make load_data

If you do not load data, you'll have to at least create a super user :

bin/django createsuperuser --username=admin --email=admin@corp.com

or change its password :

bin/django changepassword --username admin <password>

You might also need to deploy logo images in the following places :

• var/media/upload/logo-header.png
• var/media/upload/logo-login.png

bin/django loaddata development-pne

After editing etc/settings.ini, refresh the running instance with :

make deploy

You can authenticate user against a remote database table or view.

To enable this feature, fill authent_dbname and other fields in etc/settings.ini.

Expected columns in table/view are :

• username : string (unique)
• first_name : string
• last_name : string
• password : string (simple md5 encoded, or full hashed and salted password)
• email : string
• level : integer (1: readonly, 2: redactor, 3: path manager, 4: trekking manager, 6: administrator)
• structure : string
• lang : string (language code)

notes

User management will be disabled from Administration backoffice.

In order to disable remote login, just remove authent_dbname value in settings file, and update instance (see paragraph above).

Geotrek can support many types of users authentication (LDAP, oauth, ...), contact-us for more details.

This command is in charge of changing the database schema [1].

Make sure you close every pgADMIN session on the database while upgrading.

[1] http://south.aeracode.org/ticket/209

Check that the projection of your data is correct. Check that the extent of the map covers your data.

Check the value of the spatial_extent_wgs84` setting.

Check the values of your WMS settings (server name should end with ?, layers names should exist on server).

Check the values in the generated TileCache configuration in etc/tilecache.cfg.

Check that your extent (spatial_extent) is completely contained in your DEM.

For code contributors only : in order to run a development instance :

./install.sh --dev

Start local instance :

make serve

Run unit tests :

make tests

For PDF conversion server, run an instance in a separate terminal :

bin/pserve lib/src/convertit/development.ini
