Merging diverse geodata

MP constituencies

no correlation to boroughs/postcodes/anything

Photos of every OS grid

no correlation to boroughs/postcodes/anything

Internationalis(z)ation

Major differences:• base data

RoyalMail vs. Tele Atlas

• character set

• different scales UK postcode is not the same as an ES postcode

• market differences‘The flat is in central Madrid’

Exposing geodata

Google mapplet

Facebook Application

Widgets

Literally cut and paste

Open Formats• GeoRSS

• API You can have our data

• Sharing is good!Yahoo Pipes, Facebook Platform …

Why should you care?

It’s very possible to build a geocommunity without GIS

Is the professional GIScommunity relevant?

Points to consider:• Openness wins

• You can’t compete with free

• Data is becoming a commodity. Rapidly

What to do?• Communicate more

• Free your data

• Engage with innovators, don’t fight them

Questions/Discussion

Other interesting things I haven’t mentioned

• Text analysis/cleansing

• Detecting duplicates
