Urban growth visualisation

Brendan Conway has been at it again.

Using his Navigatio GIS platform and Claude coding he has created a new data visualisation app which allows you to see how cities have grown over time.

Watershed Pollution Map

 A new mapping option linked to the current river pollution issues...

Very excited to announce the launch of
THE WATERSHED POLLUTION MAP!

River health, landfills, sewage, road run-off, intensive farming, big industry, forever chemicals, abandoned mines, bathing waters, flood risk, protected areas and so much more... 🧵https://t.co/upIKfAJQhP pic.twitter.com/FnlRgip9ld

What are the sources of pollution in your own local area?

Vernacular Names Tool

The Ordnancc Survey has been collecting vernacular place names. 

It has produced an additional set of information on its mapping database which includes 9000 names which local people use to describe places which may have a more official name. This is to help locate people whose problem may occur in a location which they know by a vernacular name...

The Guardian has an article on the work.

The data layer produced is called the VNT or Vernacular Names Tool. This article explains more.

The database, hosted in the OS National Geographic Database, is a replacement for FINTAN, a mapping tool created more than ten years ago in response to a request from HM Coastguard. It was created in partnership with OS and was designed to allow users to upload any local name, alternative name or nickname for a coastal feature alongside the accurate location or existing geographic name in the mapping database. These include cliffs, caves, sandbanks, coastal car parks and buildings to name a few. This ensured that HM Coastguard responders could get to emergencies – however their location was described – with much greater confidence and speed.

On a visit to the OS HQ, the Princess Royal added her own alternative name to the database.

The Coal Authority Maps

The Coal Authority has a GIS site where you can identify the locations of previous activity to mine for coal.

This was a big part of my life growing up in South Yorkshire. My grandfather and other family members were coal miners and we knew there were coal seams running under our village and surrounding areas - I remember a house collapsing from subsidence once. Now you can find these signs of the past on this map from the Coal Authority.

The miners' strike was something else I remember well. Several friends spent a lot of time marching and fund raising. Our minibus was occasionally stopped when carrying out undergraduate fieldwork as the police thought we might be flying pickets.

The village where I lived was only a few miles from the Maltby Colliery, and there was a lot of ill feeling between those who stayed out and those who went back. Orgreave was only about four miles from home too and the TV coverage of the time was all over the local news in the evening. This was a desperate time for many. There has been a number of recent TV dramas and documentaries as it is now coming up to 40 years on from the strike - amazingly.

Land Use Cover mapping

Alasdair Rae has produced a number of excellent maps, and this is one his most useful projects to date.
This BBC News article is interesting, and explains something of the project.

 
You can use the tool linked to from above to explore your own area.
Have a guess what the percentages might be before you do this, or compare your area with the country.
There are some interesting additional facts in this blog. I like this one for example:

Buildings cover less of Britain than the land revealed when the tide goes out...

Download the whole Atlas of Land Cover in the UK here....

I put in my own postcode where I live, expecting a larger than average amount for farmland...
And unsurprisingly, it is up to 81%, with only 3% built on...

BRITICE - mapping the British Ice Sheets in Google Earth

BRITICE looks like being really useful for those studying cold environments, and the impact that the British Ice sheet had on the country, and the landforms that it left behind.
It's a project of Chris Clark and colleagues at the University of Sheffield.

There is a range of mapping available, including a Google Earth layer, and also files that can be opened in ArcGIS and other similar GIS packages.

One for those who want to get stuck in to some serious analysis of glacial features.

Thanks to Al Monteith for the tipoff to the site via Twitter.
