Transcript

  • 1. Associating Coordinates to Patients 1 ) Patient address goes into the system 2 ) If the address is valid then get the coordinates 3 ) Associate the coordinates to the patient's address umudugudu_id latitude longitude 0104020507 -1.9534521 30.651238 … … … address_id precision lat lon 34 1 -1.9534521 30.651238 … … …
  • 2. Associating Coordinates to Patients This patient's coordinates were derived from their address This patient's coordinates were collected at their house with a gps device address_id precision lat lon 34 1 -1.9534521 30.651238 237 0 -1.9812122 30.234525
  • 3. Using The Google Earth and Maps API Public internet connection Retrieve patient data in JSON Retrieve imagery from Google Web Browser Patient data
  • 4. Rendering Data In The Google Earth API
  • 5. Clicking on an icon renders patient data including great circle distance to the hospital Interactive Maps Using The Google Maps API
  • 6. Filtering The Data
    • Filtering by CD4 count, on time CD4, Distance to Hospital, Time Since Last Visit
  • 7. Open Source Spatial Data Infrastructure PostGIS Shape Files GeoServer OpenLayers WMS Module Data Sources WMS/WFS WMS/WFS Imagery uDig (Desktop App)
  • 8. Advantages of GeoServer
    • No dependence on a connection to the internet
    • Having spatial data outside of OpenMRS is more scalable
    • Data is accessible from any application capable of communicating in WMS or WFS format
  • 9. uDig Displaying Data From GeoServer
  • 10. OpenMRS Displaying Data From GeoServer Using OpenLayers
  • 11.
