Processing large OpenStreetMap datasets for geocomputational research

OpenStreetMap (OSM) is a free and openly editable map of the world. Like
24
-
Wikipedia and unlike government or corperation maintained datasets, OSM
25
-
is created and maintained by a community of volunteers, making it the
26
-
premier decentralized and fastest evolving source of geographic vector
27
-
data focussed on features relevant to human activity (e.g. roads,
28
-
buildings, cafes) on planet Earth. Unlike Wikipedia, every data point in
29
-
OSM has a geographic location and attributes must be structured as
30
-
key-value pairs. OSM is a rich source of data for geocomputational
31
-
research, but the decentralized nature of the project and the sheer
32
-
volume of data. ‘Planet.osm’ now has more nodes than there are people on
33
-
Earth, with more than 8 billion
34
-
nodes, and the rate of data
35
-
creation is increasing as the community grows, to 10 million
36
-
users in early 2023. The
37
-
size and rapid evolution of OSM are great strengths, democratising
38
-
geographic knowledge and ensuring resilience. However, these features
39
-
can make it difficult to work with OSM data.

41
-
This lecture will provide an introduction to working with OSM and will
42
-
cover the following:
43
-
44
-
How and where to download OSM data
45
-
How to process small amounts of OSM data using the osmdata R package
46
-
How to process large OSM ‘extracts’ data with the osmextract R
47
-
package
48
-
Other command line tools for working with OSM data, including the
49
-
mature and widely used osmium tool, the pyrosm Python package and
50
-
the osm2streets web
51
-
application and Rust codebase
52
-
53
-
Finally, the lecture will outline ideas for using OSM data. It will
54
-
conclude with a call to action, inspiring the use of this rich resource
55
-
to support policy objectives such as the fast and fair decarbonisation
56
-
of the global economy as societies transition away from inefficient,
57
-
polluting and costly fossil fuels.

Robin specializes in geocomputation with a focus on developing geographic methods applied to modeling transport systems, active travel, and decarbonisation. Robin has experience not only researching but deploying transport models in inform sustainable policies and more effective use of transport investment, including as Lead Developer of the Propensity to Cycle Tool (see www.pct.bike), the basis of strategic cycle network plans nationwide. Robin has led numerous data science projects for organizations ranging from the Department for Transport to the World Bank.
