maps
      
        I like maps, geojson, and data. As
        such, I end up making a lot of custom maps.
      
      Here are some of those :)

          Sheffield Stink Pipes (geojson) #

          I like stink pipes. This is a map of the 21 Grade II listed stink
          pipes in Sheffield.
        
        
          The source also has generic instructions for making a geojson file
          from any list of data from
          Historic England (i.e.,
          any collection of listed structures).
        
        
          Since creating this, I have learnt there is also an
          OpenStreetMap relation of stink pipes in Sheffield
          kept up to date by
          Paul Berry.
        
        
        
      
      
        
          Mountain Bothies (geojson) #
        
        
          source /
          map 1
          (geojson.io) /
          map 2 (my server) /
          map 3
          (the MBA)
        
        
          I made this because I wanted to choose a bothie to visit that had good
          pedestrian access, and that I could plan a route to, and the bothie
          map on MBA's (Mountain Bothies Association) website uses
          a map overlay of OS maps, which uses the "Standard" map type, which
          doesn't show common footpaths, bridleways, etc.
        
        
          So, my solution (as you see in source above) was to scrape the bothie
          locations, and create my own map, which I could then overlay onto Bing
          Maps, which (for some reason) includes a premium OS Maps layer for
          free.
        
        
          In the end (and mainly because of train timetables) we went to
          Abyssinia.
        
        
          you can also find these via OpenStreetMap data using
          Overpass Turbo.

          map 2
          (Google Maps)
        
        
          This is a map of all the service stations I found on
          https://motorwayservices.uk/
          and
          https://motorwayservices.ie/. Their map (to my knowledge) does not show all of the services, so I
          made my own. There is a nice flow of commands in the source of how I
          made the file.
        
        It comes in very handy for hitchhiking.

          Sheffield HMO (Houses in Multiple Occupation) Licences (geojson, gpx,
          kml)
          #
        
        
          source
          /

          Sheffield City Council publishes data on House in Multiple Occupation
          Licenses (HMO Licences) in its district on
          https://www.sheffield.gov.uk/housing/houses-in-multiple-occupation.
        
        
          They only post an excel file, and refused to consider posting a CSV.
          They also said that historical data is not available, and they delete
          the file every time they upload a new one. Hey-ho.
        
        
          Anyway, I downloaded it, geocoded the addresses from street names and
          postcodes into latitude/longitude coordinates, and created some data
          files, so one could view the data nicely on a map. It also has the
          bonus of being colour coded by "Permitted Occupants". Apparently some
          houses are allowed to house 93 occupants. Crazy.
        
        
        
      
      
        
          River Walks (geojson) #
        
        
          Sheffield has 5 rivers, which makes it ideal for river walking. I
          found the IDs of the rivers on OSM (Open Street Map) and created a query for
          Overpass Turbo, which is a
          tool to visualise OSM queries.
        
        
        Combined
        
          To find good-looking spots for a river walk, I combined Sheffield's
          four smaller rivers into one map using Overpass Turbo.

        Sewage
        
          In a river in a city, you should probably be aware that there are many
          storm overflow drains which dump untreated or treated sewage into the
          rivers. They should only operate in times of high rainfall, and
          I believe their use is declining.

          I enjoy a river walk. Some rivers I have enjoyed (which you can see on
          the map) are the rivers Sheaf, Rivelin, and the Porter Brook.
        
        
        
      
      
        
          Scotland Trip (gpx) #

          / map
        
        
          I went on a road trip through Scotland, and kept track of our stopping
          points. I exported several GPX files of the routes between the points,
          and used Python to make them into an SVG.

          I biked from Birmingham to Cambridge and made a lot of maps of the
          journey. You'll find a lot more information in the blog post.
        
        
        
      
      
        
          Trips to Europe #
        
        
          I like travelling as much as anyone else. I don't fly, so I end up
          getting a lot of trains whenever I go to Europe.
        
        
          For about half of my trips to Europe, I've collected GPS traces
          (either by
          manually creating them
          or using
          OwnTracks
          to record my GPS location over time). The geojson files are stored in
          a
          GitHub repository, and I made a simple interactive map using
          MapLibre GL JS
          (a JavaScript mapping library that's an Open Source version of
          MapBox.)
