2. Crowdsourcing – what is it good for?
• Spread of horse-chestnut tree leaf miner moths (Leaf
Watch / NatureLocator)
• Locations of Edinburgh City Cycleways (Innertube Map)
• Actual 3G reception quality/speed in the UK (BBC)
• Otherwise unmapped locations, e.g. North Korea
(Google)
• Infrastructure, running water, health clinic, etc. locations
in Kibera, Kenya (Open Street Map)
• Californian wineries with opening times (David Smith)
• Pollution in China (Danger Maps)
3. What does FieldTrip GB do?
All the key features:
Capture information
Images
Audio
Text
Location
High quality background maps

4. Why collect data?
Data makes “stuff” happen
Data capture costs money
Local Gov doesn’t have spare cash
We are the Experts about our neighbourhoods
So we can help out by collecting data

5. What could you collect?

6. The Basics
Download: maps and
view captured records.
Login: to a Dropbox
account
Maps: view online maps
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
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. 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
10. 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

11. Lets collect some data
Number one priority for me at moment: Ownership of shops and
brownfield sites - to support pop-up enterprises/activities.
I'm just about to put together a
map showing a rating of cycle
facilities at local supermarkets.
Places that can serve you tasty food
very quickly that are in between Fringe
venues...
A crowdsourced map of events and locations
that are genuinely safe to take kids during
edfringe would be good
Could you do a map that showed approx. queuing times for venue's
ticket offices? (Assembly - 6 minutes, Pleasance 24 minutes, venue 42
- 30 seconds)
12. Collecting data at your convenience
Loads of loo listings
All different lists (e.g.
council, RADAR)
Facilities & price
inconsistently
recorded
No records of shops,
cafes, etc.
Hard to find nearest
appropriate facilities
when you need
them.
14. So what is useful to collect?
• How to find them – location, what they look
like, where in the building they are.
• Who are they for – men, women, baby change?
• Are they accessible? Who for?
• What facilities are there?
• What do they cost?
• Are they scary/great/anything else?
15. Now for the scary demo bit…

• 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
