Blueprints for the GIS Module

We use ​OpenLayers to display Maps with some ​GeoExt widgets.

Ideas

• Basic Tasks
• complete support for Mobile devices
• complete move of Internal Feature Layers to GeoJSON
• allow swapping from embedded to full-screen without a reload of the page
• complete moving of JS code from being generated server-side to [static http://eden.sahanafoundation.org/browser/static/scripts/S3/s3.gis.js] (for caching & easier maintenance)
• integrated Legends in the West Panel
  • Simple example: ​http://api.geoext.org/1.0/examples/legendpanel.html
  • More complex example: ​GeoExplorer (add some layers)
• complete migration to GeoExplorer
• OpenStreetMap PoI Layers
• Color coded maps according to Geo-data (threats, needs, etc)
• Placing variable sized markers on the map in proportion to data (number of people in camp, number of families needing food)
• Tracking people ( John Smith was registered at Camp A, then collected food at Camp B, then volunteers at Site C), or Items (The shipment of Tarpaulins moved from site C to site D, where it was split, and then half of them have been distributed from site E)
• Having a playable timeline slider (like ​http://haiti.ushahidi.com/main)
• Identify core GIS tools
• Integrating Walking Papers (​http://walking-papers.org/) functionality into Sahana

• Merge ​http://healthscapes.org Geolytics toolkit

To display Shapefiles & Images we need to install a 3rd party server. ​GeoServer is probably a better target than ​MapServer

• GeoServer has a great in-built Admin UI
• GeoServer can be configured via REST rather than MapScript if we wish to control from within Eden itself
• GeoServer uses OpenLayers as native preview
• GeoServer has a ​Printing plugin
• ​OpenGeoSuite provides an integrated stack
• ​MapFish Studio

We should aim to be compatible with UN Logistics: ​http://www.logcluster.org/mapcenter/unsdi
