What do we do?

Digimap – a mini-revolution

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?

Digimap – Alternative representations

Alternative representations – 4 images of the same area with different styles applied.

Digimap – add your own data

Digimap Roam – 1:50 000 + Hillshade + GPX tracklog uploaded as annotation

So how do you improve interfaces?

Be prepared to failNot everything will work. Part of experimenting with an interface is

working out what doesn’t work

Be prepared to failBut remember, you will still find users who simply just don’t get it.

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

But what about mobile?

Location based everything

Data collection has changed

Technology has made data capture easier, more affordable and quicker.

Beyond the classroom

Mapping Issues : Urban vs. Rural

MapServer Masking

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?

Maps anywhere

Why save maps to the phone?

Data connection not always

available in rural areas

Streaming maps uses data

allowance

Maps load faster

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

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

Capture the data you want

Create your own data collection form and deploy it to your phone

Understand the users

Promotes good research data management through consistent capture and helps reduce blunders

• 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 GIS 7. View the results

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
