Maps and Data

We have built a set of interactive maps. If you click or tap an area on the map, you will be shown a list of links to features at the point clicked. If you then click one of the links you will be shown statistics and other data relating to the feature clicked.

The map can be dragged to centre on a different position.

You can pinch on a touch device to zoom in and out, and can use the scrollwheel to do the same if you have a mouse.

Both the maps below are synchronised so that they always show the same place at the same scale.

Parish Declarations

A map showing parish outlines with a list of parishes. If you select in the list you are shown its progress with declaring a climate emergency and the map zooms to show the parish. If you then click on the parish area, data about the parish is shown.

Current and Potential Emissions from EPCs

Map has census output areas coloured by emissions level, together with parish boundaries. Two maps are shown side by side, both maps pan and zoom simultaneously. Click on an area to see links to further data about the area.

The following presentations are available:

Road Transport Emissions

We have now analysed traffic flows and GHG emissions from road transport for the district to produce maps of emissions from each road and for each census output area.

The roads map shows major roads only when zoomed out, zoom in to show full road network detail.

Data we hold

This map shows all the layers we have. Layers can be turned on by clicking the checkbox on the left of the legend. You can then control which layers respond to clicks on the map by selecting the clickable checkbox on the legend.

Technical Documents

Several of you have asked how the maps were produced. These technical documents describe the processes in detail. The next release of the mapping application will also include brief descriptions of each field, sources of data, update frequencies, dates downloaded, and processing applied.

These more technical documents describe some of the more complex processes in detail:

  1. Could you give a short explanation of how you developed the maps? For example, the source and age of your data, what calculations were performed to work out emissions, and how accurate you think the maps and figures are?

    1. I am working on a new release of the mapping which includes more information in the details section about what each field means and the sources of information used.
      Briefly, Government figures are available for GHG emissions at district level for Industry & Commerce, Transport, Domestic, LULUCF (Land Use, Land use change and Forestry). There are some things missing from these statistics, such as emissions from farm animals, but they are a good base that is published every year.
      I am now working on a revision of domestic emissions which resolves some anomalies. I have found gas and electricity meter readings at lower levels which tally fairly closely with the overall figure, so can work out electricity and gas emissions for parishes with confidence. I am using inspector’s estimates from Energy Performance Certificates to estimate the gaps in the data. I am writing a paper to go with this which explains in more detail.
      From the government figures that leaves transport, industry and commerce. These are more difficult to do accurately, an initial estimate for transport will have to be just apportioning emissions on a per capita, or per household basis, this could probably be refined by using car ownership data if this is available at a sufficiently granular level.
      Likewise Industry and Commerce will have to be initially be fairly crude, probably based on the number / size of business premises in an area.
