Hi everyone Don't forget there is also urban/industrial infrastructure relating to water to be mapped: sewage treatment works, water treatment works, fire hydrants (see my recent blog <http://www.mappa-mercia.org/2016/12/a-guide-to-mapping-fire-hydrants-in-the-uk.html#comment-109666>) and aqueducts/pipelines (especially the buried ones like the Elan Valley Aqueduct which brings Birmingham's water from a reservoir in Wales). There's a massive project underway to create a parallel route from the River Severn for resilience purposes for the last part this aqueduct/pipeline before it reaches Birmingham. Mapping that will take a lot of effort (STW won't release any opendata maps claiming protection of national critical infrastructure - the sorry saga of which will form a future blog). It might be a satisfying project to dig out the Victorian and Edwardian archives in libraries and map the aqueducts/pipelines connecting cities to their respective reservoirs in the mountains.
Mapping fire hydrants is a nice little treasure hunt, which gives you an opportunity to revisit streets/roads that haven't been visited for a long time Regards brian On 5 January 2017 at 09:38, Jez Nicholson <[email protected]> wrote: > I use the quarterly projects to focus my attention on different aspects of > the city I live in.
