Role of CyberGIS in Analysing Urban Data

Role of CyberGIS in Analysing Urban Data

This is a talk a gave in August 2012 on the use of “CyberGIS” for the analysis of urban data. CyberGIS is a term that covers the suit of tools that are being developed to use large-scale computing infrastructures for geographic data analysis. In my talk I demonstrate the ways that we at CASA have been grappling with the “big data” of cities ranging from transport to social...

Visualising for Human Geography

Visualising for Human Geography

The publication of the International Benchmarking Review of UK Human Geography back in March was a major event for the discipline. The report concludes that the UK human geography community is setting the intellectual agenda for the subject and can therefore consider itself the best in the world. Whilst this is a great achievement, the “relative weakness in quantitative methods and GIS” (p16) was also highlighted. The authors flag the growing interest in data visualisation, and its value for information dissemination and impact, but suggest that human geographers may not be ahead of the curve in the same way as they are in other parts of the discipline. Compelling data visualisation is the key to communicating results from research widely and, perhaps most importantly, a means to inspire current and future students to work with quantitative data. More maps (and other visualisations) than ever are being produced, but many are methodologically flawed or misleading because the people who created them are great with complex software and data manipulation, but less good at...

G-I-S State of Mind

For GIS nerds only: Just to prove that GIS users are “hip” and “cool” here is a video that takes a contemporary “rap” artist’s song and adapts it with GIS- specific lyrics. I really “dig” this, especially the “sweet” line about...

Maps with ggplot2

Maps with ggplot2

The ggplot2 package offers powerful tools to plot data in R. The plots are designed to comply with the “grammar of graphics” philosophy and can be produced to a publishable level relatively easily. For users wishing to create a good map without too much thought I would recommend this worksheet. For those without their own shapefiles who rely on the “maps” package they may wish to consult Hadley Wickham‘s ggplot2 book. Data Requirements: London Sport Participation Shapefile. Download (requires unzipping) poly_coords function. Download Install the following packages (if you haven’t already done so): maptools, RColorBrewer, ggplot2 Click here to view the tutorial code....

#ffgeo: Follow Friday for all things geographical.

Just for a bit of fun and to help those of us with interests in all things geographical, spatial, GIS, maps and cartographic (I could go on…), I thought I would add “geo” to the usual Follow Friday (#ff) twitter hashtag to create #ffgeo. So if you have particularly enjoyed the geo-related tweets from one or several people this week, list their user names and include the #ffgeo hashtag so that fellow lovers of all things geo will know to check them out. It may not take off, or it could be come a weekly event. Either way you can monitor progress below or...
