  1. 1. Fieldtrip GB: Creating a customisable mapping and data capture app for the HEFE community Ben Butchart (b.butchart@ed.ac.uk) Addy Pope (addy.pope@ed.ac.uk)
  2. 2. Fieldtrip GB - Overview Home Screen Save maps for use offline
  3. 3. Authoring tool: Form Builder Create your own data collection form and deploy it to your phone
  4. 4. Authoring tool: Record Viewer Search and filter records Export as GML / geo JSON and collate data
  5. 5. Challenges developing data capture apps • Relatively high cost • Rapid advances in technology…, so can become redundant quickly • Multiple operating systems • Mobile Network signal coverage is patchy – urban focus. • Versatile apps for data collection…do not allow apps to be ‘branded’ … - proliferation of standalone apps could create clutter • Users expect apps to be intuitive and have high usability Roy, H.E., Pocock, M.J.O., Preston, C.D., Roy, D.B. & Savage, J. Tweddle, J.C. & Robinson, L.D., (2012) Understanding Citizen Science and Environmental Monitoring, UK Environmental Observation Framework, http://www.ceh.ac.uk/products/publications/documents/CitizenScienceReview.pdf (accessed 29/01/2013)
  6. 6. Fieldtrip GB Open data mashup • Strategi • Land-Form PANORAMA • Natural England • Vector Map District • OpenStreetMap
  7. 7. Why Fieldtrip GB needs its own map? Fieldtrip GB OpenStreetMap Google Maps EDINA Openstream
  8. 8. Mashup Issues 1: Partial labels out of scale Strategi labelling optimized for 1:250,000 scale causes conflicts out of scale
  9. 9. Mashup Issues 1: Manual Label Correction
  10. 10. Mashup Issues 2: Label Alignment VMD (beta) water features point labels only
  11. 11. Mashup Issues 3: Urban vs. Rural 1 mapping stack to cater for both urban and rural environments Mapserver 6.2 Masking
  12. 12. How it all works
  13. 13. Architecture Client Architecture • PhoneGap Map GENERATION ARCHITECTURE • OpenLayers • OpenStack private cloud • Apache Web Server • Mapserver 6.2 • Mapcache seeder Why PhoneGap? • PostGIS • OpenLayers map library more versatile SERVICE ARCHITECTURE • Easier to implement custom forms • Lower cost of delivering to multiple • Apache web server platforms • Mapcache (Tile cache) Data storage outsourced (Dropbox) • Python WSGI (PC API) • Citrix Netscaler load balancer • VSphere VMWare (SUN X4150 cluster)
  14. 14. Future Direction: Embracing The Sensed World Web We are planning… Sensed World Web • Make your own app. [ “a condition where as humans we begin to enhance our own human senses and connect • Capture map and annotate. those senses to networked databases” ] • Photo sketch capture. Butchart, B (2012) Towards a Sensed World Description Language, http://www.perey.com/ARStandards/[Butchart]Sensed_World_Web_AR_Standards.pdf, • Augmented Reality captures. Sixth International AR Standards Community Meeting, Geneva. • Strike and dip measurements. • Ambient noise capture. • 3d point cloud capture. but you decide….
  15. 15.
