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

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

Bugs

• #87
• #91
• #109

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?
  • bounds information - e.g. lat/long 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/long 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

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

UI

• Separate out the Internal Features from External Features in LayerSwitcher (​GeoExt skills)
  • views/gis/map_viewing_client.html +68
• Add numZoomLevels=22 (or some higher number than the default 16 so can zoom in on high res imagery better

OpenLayers

• ​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

• 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

• Image layers?
  • Added image layers from ​http://hypercube.telascience.org/haiti/uav.html using advanced JS

Load GIS data

• 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 ​EPSG:32618
• Administratrive Areas (3 levels) -- tcarobruce has a partial solution for this
  • Unofficial: ​Departments, Communes, Sections in EPSG:4326
  • Official (with projection issue): ​Departments, ​Communes, ​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:
  • ​http://hypercube.telascience.org/haiti/uav.html

  • ​GeoEye
