As part of the OpenStreetMap project, there is a humanitarian aspect, producing maps of the less developed parts of the world. These can be used for both disaster recovery, as was demonstrated after the Haiti earthquake, but also for preparedness in areas of flood or disease risk.
Maps are knowledge. They are required to coordinate (often scarce) resources in the event of a disaster or epidemic. And OSM is making these freely available to everyone everywhere, in the same way that Wikipedia is democratising knowledge.
Over the past few years, I have contributed to a number of the tasks organised by the Humanitarian OpenStreetMap Team (HOT), mapping various areas of Africa and Indonesia. Continue reading “Mapping the developing world”
When out on site visits for work (as with other times), I often record where I have gone using the GPS on my phone. It can often be handy to overlay this on a CADdrawing. Until now, converting this has been non-trivial. However, I now have a reasonable, if somewhat convoluted, workflow. Continue reading “Plotting GPS tracklogs to UK National Grid in AutoCAD”
It is possible to use the Ordnance Survey Open Data 1 to 250,000 raster maps as a background layer in JOSM. However, the positional accuracy of this scale of map is limited. This could also apply to the StreetView tiles, but they are readily available as a WMS layer, which is probably preferable. Continue reading “Using OS OpenData 250k maps in JOSM”
source: OS_OpenData_StreetView when editing OSM was becoming tiresome. Therefore I hacked together a quick sources preset based on one for Spain by user Sanchi. Perhaps this will be useful for others editing OSM in the UK using JOSM.

I have done most of my Open Street Map editing using the free JOSM Editor, as I feel it has a number of advantages over the default, Flash-based, Potlatch editor built into the website. The feature I use most is the various background image layers, but also being able to quickly loading my GPS tracks and support for other plugins are useful too.

Over the past few months I have been getting involved with the OpenStreetMap project — a Wikipedia style map that anyone can edit, and use for whatever they want.
