Boris Bikes/Barclays Cycle Hire Average Journey Times

Boris Bikes/Barclays Cycle Hire Average Journey Times

The visualisation above shows the average relative duration of Boris Bikers’ weekday journeys over a 4 month period at hourly intervals. For each time step the average journey time (in seconds) from each docking station has been calculated.This information is interesting because it shows the preference for short journeys around the City of London, whilst people on the outskirts of the the scheme (especially to the west) take longer journeys. I also like the the fact that journey times around Soho and the West End are longest around 23:00- perhaps correlating with the number of after-work drinks consumed. In one visualisation you get to see the changes in the cyclists behaviour- from the early morning commuters through to the late night cruisers The data come from Transport for London’s recent release of 1.4 million Barclays Cycle Hire journeys to their developers area (thanks to this FOI request). The data are said include all the journeys between 30 July 2010 and 3 November 2010, except those starting between midnight and...

ArcGIS for iPhone: Review

ArcGIS for iPhone: Review

ESRI have just launched their ArcGIS for iPhone Application. I have tested it out and thought I would share a my first impressions. I conducted the test on my iPhone 3GS running software version 4.0.1 and with 1 to 3 bars of 3G signal. Overall I found the app to be very impressive. You are greeted with a world map that you can instantly interact with by panning and zooming in the usual way. The map tiles loaded surprisingly quickly- it took approx 5 seconds to zoom from the above view to building level with only 1 bar of signal. Users can search for places of interest… …but this provided the only disappointment with the map appearing to lack the required data. Zooming out a little resolved this problem, but I am not sure how many people would think to do this. I suspect the problem is relatively easily  addressed and may well be in future updates. Offering standard maps is not particularly innovative and not what the app...

Free GIS Resources

Free GIS Resources

Over the last couple of days I have utilised some excellent free GIS resources. I have listed these and some others below. Geospatial Analysis: This is the free online version of de Smith, Longley and Goodchild’s excellent book by the same title. It provides full coverage of current GIS methodologies. It also provides extensive information regarding the various GIS software available. Analysing Spatial Point Patterns in R: 200 pages of workshop notes written by Adrian Baddeley. These provide extremely detailed and comprehensive overview of the spatstat in R. GeoDa Center Tutorials: A range of tutorial material provided by creators of the GeoDa Software. I would focus on the R tutorials as the GeoDa tutorials are awaiting an update in line with the software’s latest release. Spatial Stats. in ArcGIS: A preview chapter from the Springer’s Handbook of Applied Spatial Analysis. CATMOGs: A hugely successful series of publications that cover the basics of spatial analysis, they have been written by many of the pioneers in the field. Topics include The...

UCL Geography Officially becomes ESRI Development Centre

UCL Geography Officially becomes ESRI Development Centre

The UCL Geography Department has been officially awarded ESRI Development Centre (EDC) status. Paul Longley is the EDC Coordinator and as an ESRI (UK) sponsored PhD student I am the EDC GIS Specialist. This is great news as we were awarded the EDC status over a year ago (the first department in the UK to achieve this)  but have not been able to benefit from the additional software licenses or award the “EDC Student of the Year” as logistical and legal problems have had to be overcome. These are all sorted and we can now crack on with cutting edge research using ESRI software. For those interested a report on our past year’s activities as an EDC can be downloaded...
