Tracking twitter while having a writing day, and in came a tweet about some new data on supermarket locations, at the GeoLytix blog.
This hasn't previously been available as open data rather than commercially provided.
I downloaded it as an XLS and then converted it to CSV and split it into the different supermarket chains so that it can be viewed in ArcGIS Online - locations were using Postcodes for the time being, although other location options are available.
Here's the location of ALDI stories....
And here's a heatmap showing where ASDA stores are found in parts of the north of England...
Plenty of possible options now for exploring this data and looking at retail locations, demographics etc. plus supermarket location activities.
Thanks to @Geolytix for sharing the data
