=== Map-based Lat/Lon Data entry ===
 * Provide a function to allow selecting a location on a map to populate
  * Points: Lat/Lon fields
  * Polygons: WKT

=== Fix the map-based gis_location.represent ===
Currently this is commented out in {{{models/03_gis.py}}}

Want to separate out HTML representation .represent's from Export ones (i.e. all the rest).
 * Plan for this in-progress

=== Bugs ===
 * #87
 * #91
 * #109

=== GPS Conversion Tool ===
 * Accessible from /gis/location/create
 * Should support negative degrees!
 * Ideally should allow setting of N/S & E/W instead of having to remember the +/-

=== MGRS ===
 * Add MGRS Coordinate Display to Map
   * Chris Schmidt made MGRS / Lat Lon mouse position control using Jim Klassens USNG Lib
   * map.addControl(new OpenLayers.Control.MGRSMousePosition());
   * Example Code http://hypercube.telascience.org/haiti/js/haiti.js
   * Using http://hypercube.telascience.org/haiti/js/usng2.js
   * And http://hypercube.telascience.org/haiti/js/MP.js
 * Add Clickable Index (KML,GeoRSS, or Queryable WMS) to get to MGRS Map Sheets begin Produced by Talbot Brooks

=== Admin UI ===
 * 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)
  * Allow to reorder layers and select which base layer to start with

=== Feeds ===
 * Provide UI to access feeds:
  * KML feeds:
   * http://haiti.sahanafoundation.org/prod/gis/location.kml
   * http://haiti.sahanafoundation.org/prod/gis/location.kml?feature_class=Hospital
   * http://haiti.sahanafoundation.org/prod/or/organisation/4/office.kml
    * Provide an easy way to select the Org by name
   * http://haiti.sahanafoundation.org/prod/or/office.kml
  * GeoRSS feeds:
   * http://haiti.sahanafoundation.org/prod/gis/location.georss
   * http://haiti.sahanafoundation.org/prod/gis/location.georss?feature_class=Hospital
   * http://haiti.sahanafoundation.org/prod/or/organisation/4/office.georss
   *  http://haiti.sahanafoundation.org/prod/or/office.georss
  * GPX feeds:
   * http://haiti.sahanafoundation.org/prod/gis/location.gpx
   * http://haiti.sahanafoundation.org/prod/gis/location.gpx?feature_class=Hospital
   * http://haiti.sahanafoundation.org/prod/or/organisation/4/office.gpx
   * http://haiti.sahanafoundation.org/prod/or/office.gpx

  * KML Export
   * Include Marker
    * From our own site when using Portal
    * From sahanafoundation.org when using an offline instance?
     * So have a setting flag in {{{models/00_settings.py}}} for this (or gis_config table or gis_settings table?)
   * bounds information - e.g. lat/lon min/max to go in the metadata. this improves display of KML when opened in the like of GE and other apps. not required, but does improve display
   * Polygon support (currently uses Centroid)

  * GeoRSS Export
   * Polygon support (currently uses Centroid)
 
  * GPX Export
   * stick some extra info into <desc> - as auto GPS units what support bluetooth phones can recognise phone numbers and allow hands free calling
   * bounds information - e.g. lat/lon min/max to go in the metadata. this improves display of GPX when opened in the like of GE and other apps. not required, but does improve display
   * Polygon support (currently uses Centroid)

  * Import
   * GPX
    * Bulk Uploader needs finishing
   * GeoRSS
   * KML

=== UI ===
 * 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
 * Be able to Group layers in layer Tree into Folders
 * ~~Add numZoomLevels=22 (or some higher number than the default 16 so can zoom in on high res imagery better~~

=== IS_LOCATION Validator ===
Add a custom validator to {{{modules/validators.py}}} (or new {{{modules/s3gis.py}}}):
{{{
IS_LOCATION()
}}}
 * This should support the ability to select a gis_location as an admin area (i.e. we don't know the exact location, but we know the town or district)
 * This should be an AJAX auto-complete.
 * Once chosen, then the 'parent' will be set to this location

 * It should also support the ability to enter a precise Lat/Lon (or Polygon), in which case a function in the new {{{modules/s3gis.py}}} would calculate which admin area to set as the Parent automatically.

=== !OpenLayers ===
  * Cluster Strategy
   * Handle many Vectors (IE can't handle many more than 100)
   * http://openlayers.org/dev/examples/strategy-cluster.html

  * WFS Layers

  * WMS Capabilities Browser
   * http://dev.geoext.org/trunk/geoext/examples/wms-capabilities.html

  * Unzip KMZ layers

  * ~~[http://dev.openlayers.org/releases/OpenLayers-2.8/doc/apidocs/files/OpenLayers/Layer/XYZ-js.html XYZ Layers]~~
   * Generated JS seems OK, but layers aren't visible
   * XYZ layers verbatim from http://hypercube.telascience.org/haiti/uav.html work when entered as advanced JS layers
 
  * Image layers?
   * Added image layers from http://hypercube.telascience.org/haiti/uav.html using advanced JS

=== Load GIS data ===
tcarobruce working on this
   * Polygons for PaP neighborhoods from https://www.geoint-online.net/community/haitiearthquake/Geospatial%20Data%20Files/Forms/AllItems.aspx  
     * '''Projection Issue''' Departments and Communes files are in [http://www.spatialreference.org/ref/epsg/32618/ EPSG:32618]
    * Administratrive Areas (3 levels)   -- tcarobruce has a partial solution for this
     * Unofficial: [http://tcbxyz.com/haiti/HaitiAdminAreas.zip Departments, Communes, Sections in EPSG:4326]
     * Official (with '''projection issue'''): [https://www.geoint-online.net/community/haitiearthquake/Geospatial%20Data%20Files/haiti_departments01132010.zip Departments], [https://www.geoint-online.net/community/haitiearthquake/Geospatial%20Data%20Files/haiti_communes_01132010.zip Communes], [https://www.geoint-online.net/community/haitiearthquake/Geospatial%20Data%20Files/haiti_sections_01132010.zip Sections]
     * Shapefile to WKT (for calculations): {{{ogr2ogr -f CSV haiti_departments Haiti_departementes_edited_01132010.shp -lco GEOMETRY=AS_WKT}}} (OGR 1.6+)
      * '''to reproject''' with ogr2ogr, add source and transformation SRSes: {{{-s_srs EPSG:32618 -t_srs EPSG:4326}}}
      * Build a script to do this (very useful for future responses as this is a common process)
       * can run the script from a Controller so that you can access Models
       * provide UI afterwards
     * WMS for display on Map (large Vectors will slow browsers to a crawl): http://haiti.opensgi.net/geoserver/ows?service=wms&version=1.1.1&request=GetCapabilities
    * Populations
     * Shapefiles https://www.geoint-online.net/community/haitiearthquake/Geospatial%20Data%20Files/2003_Haiti_pop_estimates.zip
     * WFS (ortelius): http://haiti.opensgi.net/geoserver/ows?service=wfs&version=1.1.0&request=GetCapabilities
   * TMS/WMS layers for new imagery:
