40 min presentation to the Map Curators Workshop 2013 held in Hothorpe Hall. The presentation looks at how EDINA has used the knowledge fro running web based mapping services for 15 years to develop a new mobile mapping app. The focus is on "knowing your users" and ensuring that you fulfill their needs.

- 3. What do we do? Flicker – Panda Evans http://www.flickr.com/photos/98216330@N00/239423934/
- 4. Digimap – a mini-revolution Mocpages: http://www.mocpages.com/moc.php/135070
- 5. Digimap – the beginning Digimap Carto Beta circa 1999
- 6. Digimap – Evolution Digimap Roam – VectorMap Local
- 7. Know your users Geoscience is in the minority. What does this tell you? What do users actually want to do, or rather what do they want to avoid doing?
- 8. Digimap – Alternative representations Alternative representations – 4 images of the same area with different styles applied.
- 9. Digimap – add your own data Digimap Roam – 1:50 000 + Hillshade + GPX tracklog uploaded as annotation
- 10. So how do you improve interfaces?
- 11. Usability led interface design USeD - JISC Research infrastructure programme - Usability/Learnability
- 12. Identify the problem Select 1 data product from a choice of 16 Define area Pick data tiles Define delivery format 21 4 3 Stats: • 48,000+ Digimap users • 74,000 data requests* • 1,000,000 data tiles served* * Based on Jan 2010 – Jan 2011
- 15. Iterative test cycle Start Persona Tech/User Rec’s Testing Release 0 6 User Testing Prototype Review Revise Implement
- 16. Be prepared to fail Not everything will work. Part of experimenting with an interface is working out what doesn’t work Pic courtesy of Volvo Cars
- 17. Be prepared to fail But remember, you will still find users who simply just don’t get it. Pic courtesy of Volvo Cars
- 18. Test it, test it, test it http://used.blogs.edina.ac.uk/files/2011/09/USeD_Persona.pdf
- 19. Launch Data Download beats the old version hands down as far as I‘m concerned. The rapidity with which you can select a map extent and download all of the relevant mapping data in one go is by far much better than the slow and more manual way things used to work. Top notch stuff.” Lecturer at Northumbria University
- 20. But what about mobile? Location based everything
- 21. Data collection has changed Technology has made data capture easier, more affordable and quicker.

- 23. Know your users….. again. WHO? Geographers? Geoscience? Everyone? WHAT? Navigate? View maps? Collect data? WHERE? UK or Abroad? Rural or urban 3G network? HOW? Easy to use? Platform?
- 24. Mapping – ok, but not great
- 26. Scale Vs Screen
- 27. Custom Mapping We added another zoom level and the stack increased from 26Gb to 84Gb
- 28. Example Maps Some example maps from Fieldtrip GB
- 29. Mapping Issues : Urban vs. Rural Urban and rural areas have different needs, rural areas would benefit from a wider view / urban area might benefit from larger scale views. How do you satisfy both from one mapping stack?
- 30. Maps anywhere Why save maps to the phone? Data connection not always available in rural areas Streaming maps uses data allowance Maps load faster http://ukmobilecoverage.co.uk/map/ee
- 31. Maps anywhere Why save maps to the phone? Fieldwork in rural areas Streaming maps uses data allowance Maps load faster http://ukmobilecoverage.co.uk/map/ee But now we have to consider: Select an area Prevent user mistaking selection map for the actual map Select zoom levels? Communicate the size of the download Integrate : Prevent the app streaming maps to device that have been downloaded
- 32. Maps anywhere Preview Map: shows the detail of the mapping you will download Zoom Levels: define the number of zoom levels you want to download
- 33. Capture the data you want http://fieldtripgb.edina.ac.uk/authoring/ Create your own data collection form and deploy it to your phone
- 34. Understand the users Promotes good research data management through consistent capture and helps reduce blunders
- 35. Post Capture 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 Dropbox
- 36. PCAPI – How it works PCAPI Personal Cloud API Drop Box Flickr Google Drive? Secure HE/FE? Your Cloud Space EDINA Services Custom Forms Record Viewer Publish Records AuthoringTool FieldTripGB
- 38. Hybrid app
- 39. EDINA App – Fieldtrip GB http://fieldtripgb.blogs.edina.ac.uk/ Download maps and forms Upload captured data Capture Data: basic capture forms and GPS tracking Maps: View maps or save them for use offline
- 40. Citizen Science •Get a new Dropbox account to share with your team •Download Fieldtrip GB to your devices1.Before you start •Log into the Authoring Tool •Create a custom form and save it2. Design your form •Get the team to log into the Dropbox account •Use Sync to get the form on their devices3. Share the form •Collect data using the form •Manually correct remote points or in urban canyons4. In the field •Connect to WiFi •Get the team Sync to upload the data5. Back indoors •Log into Authoring Tool •Filter by form name and edit points if needed6. Manage your data •Export to a KML file, GeoJSON, CSV or WMS •Map the points in Google Earth, OpenLayers or a GIS7. View the results
- 41. 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
