AAG Final Call: Neogeography

Our session on Neogeography at next years AAG has proved popular, to such an extent that we are looking to split it into two sections. As such we have places left for papers, all we require is an abstract and your pin.

Session titles is ‘Concepts, Tools and Applications: The Rise of Neogeography’, final closing date is

ForDigital Urban in association with Dr Andrew Crooks from GIS Agents are organising a session at the 2009 AAG entitled “Concepts, Tools and Applications: The Rise of Neogeography”. Full details are below along with details on how to submit and abstract – note the closing date is 8th October 2008.

Below is an extended abstract for the session:

The world of Geographic Information (GI) Science has changed. It has experienced expeditious growth over the last few years leading to fundamental changes to the field. Web 2.0, specifically The Cloud, GeoWeb and Crowd Sourcing are revolutionising the way in which we gather, present, share and analyse geographic data. This renaissance in the importance of geography in the Web 2.0 world is becoming known as ‘Neogeography’.

Neogeography is geography for the general public using Web 2.0 techniques to create and overlay their own locational and related information on and into systems that mirror the real world. Location and space now represents a key part of the Web 2.0 revolution. Tagging not only the type of information but where such information is produced, who uses it and at what time, is fast becoming the killer application that roots information about interactivity generated across the web to systems that users can easily access and use in their own communication with others.

The aim of this session is twofold; first to bring together practitioners to discuss concepts and challenges that the field of Neogeography faces. Secondly, to provide an opportunity for researchers and developers to present recent tools and applications for collecting, sharing and communicating spatial data for the Neogeographer. We are actively seeking topics ranging across the entire spectrum of Neogeography, from Crowdsourcing, Digital Earths, Neogeography, Web Mashups, Volunteered Geographic Information, Virtual Worlds (e.g. Second Life) and associated Web 2.0 technologies.

Anyone who wishes to presents a paper must first register for the annual meeting, submit an abstract (no more than 250 words that describes the presentation’s purpose, methods, and conclusions). Once this has been done, you need to contact us with your program identification number (PIN), which we will use to add you to the session.

We look forward to hearing from you

Andy and Andrew

From London Datastore to MapTube: Simplifying the Process

Richard Milton here in CASA has released a new feature on the MapTube website today which will make it easier to create new maps from data in CSV files. The new update to MapTube adds a graphical user interface which allows the user to upload a data file, choose a colour scale and publish the map on MapTube directly. As Richard states, one of the driving forces behind this was the idea that creating a map should be simple enough that you could do it using an iPad. Data on the London Datastore  is in the correct format, so you can copy the CSV link directly from the site, which is exactly what has been done in the above image. Richard has created a YouTube clip showing the whole process:

This feature is still experimental, but at the moment it handles point data in lat/lon coordinates (WGS84) or OS coordinates for the UK (OSGB36). Point data can be drawn using markers, or as a heatmap showing point density. For area data, one column in the data is selected as a key field and this is joined with the geographic data stored in MapTube’s database to draw the map. For example, using the following data:
We have four columns: Constituency, Party, PartyCode and Change. In the CSV file the first line must be the column headings, then every subsequent line contains data. The CSV file would contain the following:
Constituency,Party,PartyCode,Change
Aberavon,LAB,1,LAB Hold
Aberconwy,CON,2,CON Gain
etc...
The “Constituency” column is the area key in this case, but MapTube determines this automatically when the CSV file is loaded, along with the type of geography, which is Parliamentary Constituencies. In order to colour the map, numeric data is required, so in this example, a column labelled “PartyCode” has been added where “LAB”=1, “”CON”=2, LD=”3″ etc.
The colour scale is then chosen and the finished map submitted to MapTube where it can be viewed along with any of the other maps. There are help pages accessible through the ‘i’ icon on each section which contain further information.
As mentioned before, this feature is still experimental and we will be gradually adding more geographic data to the MapTube database to allow maps to be built from additional geographies. The aim is for MapTube to be able to automatically detect the geography just by analysing the data and, at the moment, the following geographies can be used:
Government Office Regions (UK) (GOR)
Lower level super output areas (UK) (LSOA)
Medium level super output areas (UK) (MSOA)
Output Areas (UK) (OA)
Postcode Districts (UK) (PostcodeDistricts)
County and Unitary Authority (UK) (CountyUA and ONSCountyUA)
Districts (UK) (Districts and ONSDistricts)
Census Area Wards (UK) (CASWards)
World Borders 2010 (WorldBorders2010ISO2 and ISO3 using the ISO country codes)
Parliamentary Constituencies 2010 (UK) (PCON2010)
US States and Zip code areas will be added shortly, along with administrative and Census boundaries for other parts of the World.

The underlying technology is used on the SurveyMapper site and for other real-time visualisations like http://bigdatatoolkit.org/2011/07/26/1yeartogo/ which shows tweets using the #1yeartogo hashtag for the London 2012 Olympics.


We aim to enhance this further over the coming months as MapTube is at the heart of GEMMA (Geographical Engine for Mass Mapping Applications), its an interesting step forward in rapid visualisation from data portals. Thanks as ever go to Richard for his work on MapTube and its every increasing number of users.
