During lockdown it’s been difficult for me to go long distances to map; instead I’ve tried to fill in every house in the SW14 postal district, consisting of East Sheen and Mortlake, where only about half of them had been mapped before; I realised I could fit ground surveys into the allowed daily exercise. I have also tidied Mortlake station, which had been a complete mess, and completely redrawn the landuse polygons northeast of the level crossing, which had previously put retail in the wrong place.
