David Maguire of ESRI Inc. gave a run through of the current beta release of ArcGIS Explorer at the Spatial Literacy in Teaching Day held at the Royal Geographical Society, London. After Googles success with Google Earth the development of ArcGIS Explorer was inevitable but the interest is in how ESRI is distancing itself from the Google Market towards the professional GIS community.
This is not a surprise in itself but by moving towards spatial analysis over the web it paves the way for opening up the world of GIS analysis to the masses. There are a number of notable features in ArcGIS Explorer, firstly the inclusion of over 700 analysis models allowing queries relating to, for example, view sheds to be run within the system. While this is a no brainier for users of the Arc Desktop line of software it is an eye opener when you realise that you can put this on every desktop of every local authority.
For a world of GIS which has been until now limited to people coming out of MSc courses it is moving towards opening up GIS for all and sundry, a change which could have a dramatic impact on the use of GIS in general.
Secondly a feature that we thought we would of seen in Google Earth by now is Facade Mapping. ArcGlobe already has close integration with systems such as 3DMax and SketchUp allowing textures to be pasted onto buildings, increasing the level of realism in 3D city models. The integration of this into ArcGIS Explorer is of interest to not maybe the GIS community but more towards architects and urban planners – it certainly has us excited.
As an interesting side note a view was made on Microsoft’s Virtual Earth which was likened to a ‘Destroyer sucking up vast amounts of data’. Google Earths current status was compared to the popularity of the now almost defunct Netscape Navigator which was quickly surpassed by Microsoft Explorer.
Time will tell what will happen when the three Digital Earths from the main players are in the market place, but with the systems free to download and use it is an interesting time in the world of Distributed Digital Environments.
Spatial Literacy in Teaching (Splint) Centre of Excellence in Teaching and Learning (CETL),is a joint initiative led by the Centre for Advanced Spatial Analysis at University College London, the University of Leicester and the University of Nottingham.

Its all very well creating a 3D city but it needs the addition of other factors to add to the level of realism – one of these is people. A few years ago we used the ActiveWorlds system to import buildings and create an online community with avatars walking down the streets. This is fine for a few people but if you want to simulate crowds in a city scene you need to turn to agent modelling.
To date this has been notoriously tricky with a high demand on both resources and technical expertise. Which is why we are interested in the new Crowd Choreography tool called Crowd IT.
Currently available in a free Beta version it allows the visualisation of over 40,000 crowd agents in a scene. We will be looking closer into this next week and if the results are good in city models we will post a couple of movies.
If people are interested in the multi-user avatar work a couple of papers detailing the projects are also now available in PDF format:
1) 30 Days in ActiveWorlds – Community, Design and Terrorism in a Virtual World. The paper featuees as chapter 8 in the book ‘The Social Life of Avatars’, Ralph Schroeder (Editor), Springer-Verlag UK.
2) ActiveWorlds: Geography and Social Interaction in Virtual Reality, written with Ralph Schroeder and Avon Huxor, published in Futures, 33 (2001) 569-587.
