I need to convert 650 OS national grid references to easting and northing (m). I've seen some of the online conversion tools, has anyone come across a package for R/Python/QGIS/Grass/etc. that I can incorporate into a workflow? Failing that, which online (batch) conversion tool do you prefer?

Does anyone know how I can get this in a shp file format? Or at least make it play nicely with gdal!

I did find a shp version here: https://saspac.org/data/2011-census/scotland-2011/, but the data zone codes don't match the others I'm working with...

v.net.distance network analysis for all GB postcodes (1.6M) to train stations (3k) via Ordnance Survey Open Roads (3M), mapped in CartoDB: https://mikerspencer.cartodb.com/viz/c7cf448e-2727-11e6-8d2f-0ecd1babdde5/public_map. For those interested, it took ~ 23 hrs of processing time running single core on an Intel i5 4460 and used up to 16GB of ram and 6GB of swap partition. Follow the school/hospital example to try for yourself! https://grass.osgeo.org/grass70/manuals/v.net.distance.html

I've been trying out CartoDB via the QGIS plugin. Here's a map showing the distance from Scottish postcodes to the nearest train station, using Ordnance Survey Open Roads and network analysis in GRASS.

If anyone would like to use my ticket for today's Scottish meet up, go ahead. I'm calling in sick.

Here's a walk through for using GRASS and SQLite with R for data management, analysis and scripting:

Example uses daily satellite data from MODIS.
