Geographic Data
What’s so special about it?
![Page 3: Opening of Geographic Data](https://reader034.vdocument.in/reader034/viewer/2022042713/54850ca2b4af9fb55d8b4886/html5/thumbnails/3.jpg)
When did most people start to take note of Ajax?
![Page 4: Opening of Geographic Data](https://reader034.vdocument.in/reader034/viewer/2022042713/54850ca2b4af9fb55d8b4886/html5/thumbnails/4.jpg)
When they first saw Google Maps and asked how it works?
![Page 5: Opening of Geographic Data](https://reader034.vdocument.in/reader034/viewer/2022042713/54850ca2b4af9fb55d8b4886/html5/thumbnails/5.jpg)
Why?
![Page 6: Opening of Geographic Data](https://reader034.vdocument.in/reader034/viewer/2022042713/54850ca2b4af9fb55d8b4886/html5/thumbnails/6.jpg)
because maps are useful!
and data used to make the map is even more useful
![Page 7: Opening of Geographic Data](https://reader034.vdocument.in/reader034/viewer/2022042713/54850ca2b4af9fb55d8b4886/html5/thumbnails/7.jpg)
... but, someone forgot to put the download button
![Page 8: Opening of Geographic Data](https://reader034.vdocument.in/reader034/viewer/2022042713/54850ca2b4af9fb55d8b4886/html5/thumbnails/8.jpg)
Why would we need a download button/data?
Don’t the people who really need it have it already?
![Page 9: Opening of Geographic Data](https://reader034.vdocument.in/reader034/viewer/2022042713/54850ca2b4af9fb55d8b4886/html5/thumbnails/9.jpg)
I want to create themed cartography
![Page 10: Opening of Geographic Data](https://reader034.vdocument.in/reader034/viewer/2022042713/54850ca2b4af9fb55d8b4886/html5/thumbnails/10.jpg)
I want to create my own a routing server
![Page 11: Opening of Geographic Data](https://reader034.vdocument.in/reader034/viewer/2022042713/54850ca2b4af9fb55d8b4886/html5/thumbnails/11.jpg)
... I want to route in Tehran ...

and route my bike to get here today
![Page 13: Opening of Geographic Data](https://reader034.vdocument.in/reader034/viewer/2022042713/54850ca2b4af9fb55d8b4886/html5/thumbnails/13.jpg)
What about for building other open government sites
![Page 14: Opening of Geographic Data](https://reader034.vdocument.in/reader034/viewer/2022042713/54850ca2b4af9fb55d8b4886/html5/thumbnails/14.jpg)
What about for building other open government sites
as at 21 December no way to get postal regions boundaries for Australia without paying for non-commercial user
![Page 15: Opening of Geographic Data](https://reader034.vdocument.in/reader034/viewer/2022042713/54850ca2b4af9fb55d8b4886/html5/thumbnails/15.jpg)
What about for more pressing uses?
as if routing my bike isn’t pressing enough
![Page 16: Opening of Geographic Data](https://reader034.vdocument.in/reader034/viewer/2022042713/54850ca2b4af9fb55d8b4886/html5/thumbnails/16.jpg)

What about for Predicting Bush fires?
Geo-Temporal Data Global Challenges
![Page 18: Opening of Geographic Data](https://reader034.vdocument.in/reader034/viewer/2022042713/54850ca2b4af9fb55d8b4886/html5/thumbnails/18.jpg)
What about for Climate Change Research?
Geo-Temporal Data Global Challenges

The Geographic Questions
![Page 20: Opening of Geographic Data](https://reader034.vdocument.in/reader034/viewer/2022042713/54850ca2b4af9fb55d8b4886/html5/thumbnails/20.jpg)
Where? and Why there?
![Page 21: Opening of Geographic Data](https://reader034.vdocument.in/reader034/viewer/2022042713/54850ca2b4af9fb55d8b4886/html5/thumbnails/21.jpg)

Increasingly we want to answer Geo-Temporal questions
![Page 24: Opening of Geographic Data](https://reader034.vdocument.in/reader034/viewer/2022042713/54850ca2b4af9fb55d8b4886/html5/thumbnails/24.jpg)

So way can’t we just have the geographic data?
To create say a poverty map for analysis on directing my donations
