willycs40Understanding the effect of limited precision GPS data on speed distributions
I've been looking at speed distributions derived from GPS tracking data. When I started to see some strange peaks in the distribution, I investigated to see if they were being caused by the limited precision of my GPS coordinates (My east/west readings were on ~1m precision, but north/south coordinates to only ~11m.) Take a look at this notebook, where I: I [...]

I have Sonos speakers in my flat. In combination with Spotify, this allows me to play just about whatever music I want, in whichever rooms of the flat, simply by opening the Sonos app on my phone and searching for the artist. The biggest challenge is deciding what to listen to. I also have a record [...]
willycs40 Video SonartUsing the GDAL library to convert spatial coordinates from Northings and Eastings to WGS84
I have written before about geospatial data types and the open source libraries which can be used to manipulate them. Today, I needed to take some geospatial data which was in a database with northing and easting fields (basically ordinance survey gridpoints), and convert it to a WGS-84 coordinate system (latitude, longitude used by most GPS systems […]
