the GPS Remote data entry from

hilltops can be carried out

Fill in the form: Drop down menus are quicker

than typing Sliders can also speed data

entry

Edit & Share

Easy Data Sharing: Sync to upload data Filter data by form name Visualise your data on a

basemap Edit collected data Export to kml, GeoJson,

csv, wms* Share maps through

Architecture

Service Architecture:• Apache web server • MapCache (Tile cache)• Python WSGI (PC API)• Citrix Netscaler load balancer• VSphere VMWare (SUN X4150

cluster)

Map Generation Architecture:• OpenStack private cloud • Apache Web Server• MapServer 6.2 • MapCache seeder• PostGIS

App Architecture:• Data storage outsourced• PhoneGap• OpenLayers

Why PhoneGap?• OpenLayers library more versatile• Easier to implement custom forms• Lower costs
