Hi all, A friend has come to me with an interesting-sounding request, and I just wondered how feasible it might be. He has a database of UK postcodes and some measurement or other (not sure what yet) and would like to create a heat map. Neither of us are techies, but I've been contributing to OSM for a year now and am familiar with JOSM and (to a lesser extent) QGIS. How difficult a project is likely to be? (bearing in mind I'd be doing it in my spare time as a favour and for my personal interest)
I assume you'd first have to convert the postcodes to lat/lon? Then I'd need a rendering tool for the "heat" colours, and then a simple base map on which to overlay it (just thinking out loud now). It sounds like the sort of thing it'd be useful to have a tutorial for. If one exists, great! If not, and if I'm successful, I might have a go at writing one. Thanks in advance, David. (user Pgd81)
