geocamMapSet -- Django app for managing multi-layer mapsets with mapSetJSON

The geocamMapSet Python/Django app provides a basic map layer editor interface that can be easily integrated with other websites. It is built on a Javascript library, geocamMapSetLib.js, which can can add an editor to any webpage with just a few lines of code.

In fact, once you include the JS libraries and set up your map in a web page, it takes just one additional statement to deploy the entire map layer editing interface:

mgr = new geocamMapSet.MapSetManager(“/mymapset.json, map, ‘manageDiv’, 'libraryDiv');

Setting up

You can get geocamMapSet via Github by saying:

git clone git@github.com:geocam/geocamMapSet.git

To run the application with the integrated items, do the following (assuming your git clone is in /home/user/python/geocamMapSet):

cd /home/user/python/geocamMapSet
export PYTHONPATH=$PYTHONPATH:$PWD/geocamMapSet
python manage.py syncdb
python manage.py runserver

Once the server is running, navigate to the landing page:

http://localhost/

Or, navigate straight to the editor, which is currently available here:

http://localhost/mixer/test/1/edit

Using the libraries in your web pages

The geocamMapSet git repository integrates the following:

  • the actual geocamMapSet Django app, in subtree geocamMapSet
  • the mapSetJSON management library, in subtree geocamMapSet/static/geocamMapSet/js
  • an example Django site, in subtree example

First include the required JS libraries in your page:

<script type="text/javascript" src="http://maps.googleapis.com/maps/api/js?sensor=false"></script>
<script type="text/javascript" src="{{ STATIC_URL }}external/js/jquery-1.7.1.min.js"></script>
<script type="text/javascript" src="{{ STATIC_URL }}external/js/jquery-ui-1.8.18.custom.min.js"></script>
<script type="text/javascript" src="{{ STATIC_URL }}geocamMapSet/js/geocamMapSetLib.js"></script>

Next provide div tags where you want to insert the mapset editor and library:

<table>
  <tr>
    <td><div id="map_canvas"></div></td>
    <td><div id="mapset_canvas"></div></td>
    <td><div id="mapsetlib_canvas"></div></td>
  </tr>
</table>

Now you can add a map, the simple mapset editor, and layer library (aka feed finder) to your page:

var mapOptions = {
    center: new google.maps.LatLng(35, -95),
    zoom: 4,
    mapTypeId: google.maps.MapTypeId.ROADMAP
};
map = new google.maps.Map(document.getElementById('mapDiv'), mapOptions);
mgr = new geocamMapSet.MapSetManager(“/mymapset.json, map, ‘manageDiv’, 'libraryDiv');

Hosting the libraries on your web site

The mapSetJSON management library geocamMapSetLib.js can be hosted on your site. To get a copy, clone the geocamMapSet project or download the latest source from the Github project page. Then copy the library to the location of your Javascript files for your site.

You will additionally need to include jQuery in your app, as it is required by the geocamMapset library. If you are not already using jQuery you can use the version that is included with the geocamMapSet application.

The geocamMapSetLib.js library is located within the project hierarchy here:

geocamMapSet/static/geocamMapSet/js/geocamMapSetLib.js

The jQuery libraries can be found here:

geocamMapSet/static/external/js/jquery-1.7.1.min.js
geocamMapSet/static/external/js/jquery-ui-1.8.18.custom.min.js

Contributing

Maintanence of the mapSetJSON specification and development on this application is managed by NASA and Carnegie Mellon University, as part of the larger geocam disaster response management initiative. However, third-party development and use is strongly encouraged.
