bitnerd & flavour coordinating

 * Provide admin UI for feature_to_feature_group, feature_class_to_feature_group, etc
  * {{{controllers/gis.py}}} & {{{views/gis/...}}}
  * Features are stored in the table gis_location
  * Feature Classes are types of Feature & determine their Marker (Icon): gis_feature_class
  * Feature Groups are collections of Features & Feature Groups & determine whether they appear as a separate layer on the Map to be enabled/disabled: gis_feature_group
  * There are Many-to-Many tables linking these together (defined in {{{models/03_gis.py}}})
  * There are basic Controller functions for editing these resources, however they aren't fully-exposed to users (need to type URL manually)
  * We want nice User interface for these & menus (menus for GIS need some wider cleanup work anyway)

  * KML Export
   * Include Marker?
   * Polygon support (currently uses Centroid)
   * Provide UI to access per-featuregroup feeds:
    * http://localhost:8000/sahana/gis/location?feature_class=Shelter
    * http://localhost:8000/sahana/gis/location?feature_class=Shel%

  * GeoRSS Export
   * Polygon support (currently uses Centroid)
   * Provide UI to access per-featuregroup feeds
 
  * Separate out the Internal Features from External Features in !LayerSwitcher ([http://geoext.org/tutorials/layertree-tutorial.html#filtering GeoExt] skills)
   * {{{views/gis/map_viewing_client.html}}} +68

  * Popups for KML/GeoRSS overlays (works in Chrome & IE8, but not FF)
   * {{{views/gis/ol_layers_georss.js}}}
   * {{{views/gis/ol_layers_kml.js}}}
{{{
<crschmidt> so two selectfeature controls don't work
<crschmidt> they work in safari because safari fails at SVG
<crschmidt> so you need to fix your code
<crschmidt> specifically, what you should do is:
<crschmidt>  1. Change from "OnFeatureSelect" on the control to registereing for the "Featureselected" Event on the layer
<crschmidt> (The API is a bit different; featureselected event functions get an 'evt' object that has a .feature property you can access)
<crschmidt>  2. Create a single SelectFeature control with multiple layers: new OpenLayers.Control.SelectFeature([layer1, layer2]);
<flavour> We already do 2. within KML/GeoRSS/Internal Features, so what we need is a single one for all 3 types: good copy
<flavour> I'd seen 1. in some examples
<crschmidt> yeah
<crschmidt> it's the more recent style
<crschmidt> the 'onfeatureselect' stuff is old and busted because it wasn't well thought out
<crschmidt> http://hypercube.telascience.org/haiti/uav.html
<crschmidt> there's a reasonably concise example there
<crschmidt> as well as http://docs.openlayers.org/library/overlays.html#interaction
