This project contains the sources for the map at http://osmcamera.tk

Installation

In this paragraph, you are supposed to have yet configured a LAMP server on which the application will be installed.

1. Setting up the database

• Enter the init_cameras/db directory.
• modify the password that will permit to modify the camera database in createDb.sql.
• execute the following command :
  mysql -h localhost -u root --password=[mysql root passwd] < createDb.sql

2. Initializing the cameras in the database

• You may just execute the rqt.sql script. It will initialize the database with the data from the first Odbl planet file (09/14/2012).
  mysql camera -h localhost -u camera --password=[camera user passwd] < rqt.sql
• As an alternative, you may download your own planet or an extract, and get the cameras from it :
  • download the file or an extract and put it in the init_cameras directory. You may download extracts, like Monaco (which is easier to perform tests) at http://www.geofabrik.de/data/download.html. Or you may download a full planet file from the torrent found at ftp://ftp.spline.de/pub/openstreetmap/torrents/.
  • execute the extraitVideosurv.sh script (that script requires osmosis : see http://wiki.openstreetmap.org/wiki/Osmosis/Installation). It will create a surveillance.osm file and a rqt.sql file. This may be long.
  • then execute the following command :
    mysql camera -h localhost -u camera --password=[camera user passwd] < rqt.sql

3. Set up the automatic update of the cameras

• Enter the update_cameras repository.
• The automatic update is based on the sequenceNumber comparison between the current state.txt from the replicate server, and the locally stored lastState.txt. So if you downloaded a planet file, you should modify the sequenceNumber in the lastState.txt file accordingly.
• Rename config.php.example file, and edit it to enter the database password you configured for the database user "camera".
• Add the update script to your crontab. Execute :
  crontab -e
  and enter the following line :
  * * * * * [path to your update_cameras directory]/update_camera.sh > /dev/null 2>&1
• In one minute, you'll see that the update script creates log files in the update_cameras/logs directory.

4. Set up the application on the apache server.

• enter the www directory, and copy the config.php.example file to config.php. Edit it to set up the values you wish.
• get the Jacob Toye's IconLabel plugin for Leaflet. You can download Icon.Label.css and Icon.Label.js from https://github.com/jacobtoye/Leaflet.iconlabel/tree/master/src (Note : I don't distribute it, as I didn't find under which licence it is released).
• If no other application is installed on your Apache server, you may simply copy the www directory content to your /var/www directory (and remove the pre-existing index.html from that directory). In any other case you may declare a virtual host. Here is the virtual host definition I use :
  <VirtualHost *:80> ServerAdmin contact@osmcamera.tk
ServerName www.osmcamera.tk
ServerAlias osmcamera.tk *.osmcamera.tk

DocumentRoot /var/www/camera
<Directory />
Options FollowSymLinks
AllowOverride None

<Directory /var/www/camera>

• Leaflet, by cloudmade : the map is based on the leaflet API (linked from the index.php. I don't care the licence as I don't redistribute it...)
• IconLabel plugin for Leaflet, by Jacob Toye : this plugin is used to display the clusters at low zoom levels. The style used by the map is from an example in that plugin sources.

  I just saw that there now exists (since Sept 23) a Leaflet.Label plugin that should be better for what we are doing...
