or saved ones offline
http://fieldtripgb.blogs.edina.ac.uk/
Capture Data: basic
capture forms and GPS
tracking
Sync: Uploads and
downloads captured
data from Dropbox
4. Why does Fieldtrip GB need
its own map?
Fieldtrip GB
OpenStreetMap
Google Maps
OS OpenData

5. The Mapping
Strategi
Vector Map District
Natural England
OS Street View
Land-Form PANORAMA
OpenStreetMap

6. Urban vs. Rural
Quality Mapping in all
locations:
One mapping stack for both
urban and rural environments
http://fieldtripgb.blogs.edina.ac.uk/
Mapserver 6.2 Masking
7. Why save maps to the
phone?
No need to be online to
view maps
Streaming maps uses data
allowance
Maps load faster from
memory
Offline Mapping
Preview Map:
Shows the detail
of the mapping
for your location.
Zoom Levels:
Set the number of zoom
levels you want to download

9. Custom Forms
Easy data management:
Consistent terms
Single data structure
Set increments aid estimates
Reduced errors
consistent errors at least!

10. Capture Data
http://fieldtripgb.blogs.edina.ac.uk/
Update the location:
Urban canyons can confuse
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
11. 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
Dropbox

12. Workflow
http://fieldtripgb.blogs.edina.ac.uk/
•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

14. 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

15. Future Directions:
We are planning…
Capture map and annotate
Photo sketch capture
Augmented Reality captures
Strike and dip measurements
Ambient noise capture
3D point cloud capture
Dichotomous Keys
