The Revolution

GIS has been a specialized backroom technology for many

years

need GIS maps

KML and GeoRSS are

good formats

Sparse data

KML is child’s

play!

So is

including iPhone etc

You can use KML in lots of placesKML uploaded to GeoCommons and used for thematic mapping

“Government’s record year of data loss” Daily Telegraph, UK, 2008

http://bit.ly/c1ry5s

The biggest single loss was in November when Alistair Darling, the Chancellor, revealed two CDs with personal details of 25 million child benefit claimants and their parents had gone missing in the post.Three weeks ago Ruth Kelly, the Transport Secretary, admitted that the details of three million learner drivers had gone missing when a hard drive was lost in Iowa.

Last February it emerged 80 passports are lost in the post every month.

Last month, CDs with personal information on thousands of benefit claimants were found at the home of a former contractor to the Department of Work and Pensions.

There is a strong case that

your data

more secure

is

in the cloud

Usability

I highly recommend this book

My top 3 rules for good usability

Do usability testing1

Do usability testing2

Do usability testing3

flic.kr/p/72M6Lflic.kr/p/53WUkg

Doing a usability test

Put application in front of user

Shut up Watch

flic.kr/p/7UqPo1

We don’t read web pages, we skim them

flic.kr/p/6Ab8j

We don’t evaluate all the options, we pick the first

plausible one

What the designer sees

What the user sees

What the user sees

What the user sees

We usually just see a fraction of what is on the

page

Use conventions

Omit needless words

Get rid of half the words on each page,

then get rid of half of what’s leftKrug’s third law of

usability

Don’t make me think

flic.kr/p/28o3cz

Krug’s first law of usability
