TwitterThe Access Network Map of England
is a national composite dataset of Access layers, showing analysis of extent of
Access provision for each Lower Super Output Area (LSOA), as a percentage or
area coverage of access in England. The ‘Access Network Map’ was developed by
Natural England to inform its work to improve opportunities for people to enjoy
the natural environment. This map shows, across England, the
relative abundance of accessible land in relation to where people
live. Due to issues explained below, the map does not, and cannot, provide
a definitive statement of where intervention is necessary. Rather,
it should be used to identify areas of interest which require further
exploration. Natural England believes that places where
people can enjoy the natural environment should be improved and created where
they are most wanted. Access Network Maps help support this work by
providing means to assess the amount of accessible land available in relation
to where people live. They combine all the available good quality data on
access provision into a single dataset and relate this to population.
This provides a common foundation for regional and national teams to use when
targeting resources to improve public access to greenspace, or projects that
rely on this resource. The Access Network Maps are compiled from the
datasets available to Natural England which contain robust, nationally
consistent data on land and routes that are normally available to the public
and are free of charge. Datasets contained in the aggregated
data:•
Agri-environment
scheme permissive access (routes and open access)•

point data only Due to the quantity and complexity of data
used, it is not possible to display clearly on a single map the precise
boundary of accessible land for all areas. We therefore selected a
unit which would be clearly visible at a variety of scales and calculated the
total area (in hectares) of accessible land in each. The units we
selected are ‘Lower Super Output Areas’ (LSOAs), which represent where
approximately 1,500 people live based on postcode. To calculate the
total area of accessible land for each we gave the linear routes a notional
width of 3 metres so they could be measured in hectares. We then
combined together all the datasets and calculated the total hectares of
accessible land in each LSOA. For further information about this data see the following links:Access Network Mapping GuidanceAccess Network Mapping Metadata Full metadata can be viewed on data.gov.uk.

Statutory Main Rivers Map is a spatial (polyline) dataset that defines statutory watercourses in England designated as Main Rivers by the Environment Agency.
Watercourses designated as ‘main river’ are generally the larger arterial watercourses. The Environment Agency has permissive powers, but not a duty, to carry out maintenance, improvement or construction work on designated main rivers.
All other open water courses in England are determined by statute as an ‘ordinary watercourse’. On these watercourses the Lead Local flood Authority or, if within an Internal Drainage District, the Internal Drainage Board have similar permissive powers to maintain and improve.

TwitterOpenStreetMap (openstreetmap.org) is a global collaborative mapping project, which offers maps and map data released with an open license, encouraging free re-use and re-distribution. The data is created by a large community of volunteers who use a variety of simple on-the-ground surveying techniques, and wiki-syle editing tools to collaborate as they create the maps, in a process which is open to everyone. The project originated in London, and an active community of mappers and developers are based here. Mapping work in London is ongoing (and you can help!) but the coverage is already good enough for many uses. Browse the map of London on OpenStreetMap.org Downloads: The whole of England updated daily: england.osm.bz2 ~185M - .osm formatted raw XML data (compressed) england.shp.zip ~156M - ESRI shapefiles For more details of downloads available from OpenStreetMap, including downloading the whole planet, see 'planet.osm' on the wiki.

The National Trees Outside Woodland (TOW) V1 map is a vector product funded by DEFRA’s Natural Capital and Ecosystem Assessment (NCEA) programme produced under Forest Research’s Earth Observation for Trees and Woodlands (EOTW) project.
The TOW map identifies canopy cover over 3m tall and 5m2 area which exists outside the National Forest Inventory (National Forest Inventory - Forest Research). Canopy cover is categorised into the following woodland types - lone trees, groups of trees and small woodlands.
The data set was derived from the Vegetation Object Model (VOM) (Environment Agency, EA), the National Lidar Survey (EA), and Sentinel-2 (European Space Agency) imagery using spatial algorithms. The method is fully automated with no manual manipulation or editing. The map and its production method has been quality assured by DEFRA science assurance protocols and assessed for accuracy using ground truth data.
Because the process classifies objects based on proximity to features within OS mapping, there could be some misclassifications of those objects not included in the OS (specifically: static caravans, shipping containers, large tents, marquees, coastal cliffs and solar farms).
This is a first release of this dataset, the quality of the production methods will be reviewed over the next year, and improvements will be made where possible.
The TOW map is available under open government licence and free to download from the Forestry Commission open data download website (Forestry Commission) and view online on the NCEA ArcGIS Online web portal (Trees Outside Woodland). A full report containing details on methodology, accuracy and user guide is available.

TwitterUsing a range of different data sources Natural England has collated a map showing the extent of peatlands in England. For the purposes of this project, peatlands have been classified into three types based on the source of the information but assumed to have the following general characteristics:■ Deep peaty soils: Areas covered with a majority of peat >40cm deep.■ Shallow peaty soils: Areas with a majority of soils with peat 10–40cm deep.■ Soils with peaty pockets: Areas of mostly non-peat soils, supporting smaller pockets of deep peat (such as flushes or exposures of buried peat) too small to map at a national scale.Reported in Natural England's publication England's Peatland - carbon storage and greenhouse gases (NE257).We have have shared this data with permission from Natural England.

This dataset presents the mean topsoil (0-15 cm) organic carbon concentration (g kg-1) and measures of its variability at 1 km resolution across Great Britain. The mean and variability metrics were calculated from an ensemble of eight previously published digital soil maps applied to all 1 km grid cells across GB where data were available from all eight maps. Four of the maps were generated from the 2007 UKCEH Countryside Survey topsoil data, two of which are available online to use. Two maps are from the International Soil Reference and Information Centre, ISRIC: SoilGrids250m v.1 (2017) and v.2 (2020) which are free to download. Two maps are from the EU’s Joint Research Centre (JRC): the OCTOP map of 2004 and LUCAS map of 2014 which are both free to download. The dataset comes in the form of a seven-band raster tiff file, with each band representing the following: 1. Mean predicted soil organic carbon concentration (g kg-1) of all eight maps at each 1 km grid cell 2. Standard deviation (g kg-1) of all eight maps at each 1 km grid cell 3. Coefficient of variation (unitless; the standard deviation divided by the mean) at each 1 km grid cell 4. Signal to noise ratio (unitless; the mean divided by the standard deviation) at each 1 km grid cell 5. Name of the map that deviates the most from the ensemble mean at each 1 km grid cell 6. Relative size (%) of the largest difference from the ensemble mean at each 1 km grid cell 7. Relative size of the largest difference from the ensemble mean expressed as the number of standard deviations exceeded at each 1 km grid cell This work was supported by the Natural Environment Research Council award number NE/R016429/1 as part of the UK-SCAPE programme delivering National Capability.

TwitterLiving England is a multi-year project which delivers a broad habitat map for the whole of England, created using satellite imagery, field data records and other geospatial data in a machine learning framework. The Living England habitat map shows the extent and distribution of broad habitats across England aligned to the UKBAP classification, providing a valuable insight into our natural capital assets and helping to inform land management decisions. Living England is a project within Natural England, funded by and supports the Defra Natural Capital and Ecosystem Assessment (NCEA) Programme and Environmental Land Management (ELM) Schemes to provide an openly available national map of broad habitats across England.This dataset includes very complex geometry with a large number of features so it has a default viewing distance set to 1:80,000 (City in the map viewer).Process Description:A number of data layers are used to develop a ground dataset of habitat reference data, which are then used to inform a machine-learning model and spatial analyses to generate a map of the likely locations and distributions of habitats across England. The main source data layers underpinning the spatial framework and models are Sentinel-2 and Sentinel-1 satellite data from the ESA Copernicus programme, Lidar from the EA's national Lidar Programme and collected data through the project's national survey programme.

TwitterWith this add in it is possible to create map templates from GIS files in KML format, and create choropleths with them. Providing you have access to KML format map boundary files, it is possible to create your own quick and easy choropleth maps in Excel. The KML format files can be converted from 'shape' files. Many shape files are available to download for free from the web, including from Ordnance Survey and the London Datastore. Standard mapping packages such as QGIS (free to download) and ArcGIS can convert the files to KML format. A sample of a KML file (London wards) can be downloaded from this page, so that users can easily test the tool out. Macros must be enabled for the tool to function. When creating the map using the Excel tool, the 'unique ID' should normally be the area code, the 'Name' should be the area name and then if required and there is additional data in the KML file, further 'data' fields can be added. These columns will appear below and to the right of the map. If not, data can be added later on next to the codes and names. In the add-in version of the tool the final control, 'Scale (% window)' should not normally be changed. With the default value 0.5, the height of the map is set to be half the total size of the user's Excel window. To run a choropleth, select the menu option 'Run Choropleth' to get this form. To specify the colour ramp for the choropleth, the user needs to enter the number of boxes into which the range is to be divided, and the colours for the high and low ends of the range, which is done by selecting coloured option boxes as appropriate. If wished, hit the 'Swap' button to change which colours are for the different ends of the range. Then hit the 'Choropleth' button. The default options for the colours of the ends of the choropleth colour range are saved in the add in, but different values can be selected but setting up a column range of up to twelve cells, anywhere in Excel, filled with the option colours wanted. Then use the 'Colour range' control to select this range, and hit apply, having selected high or low values as wished. The button 'Copy' sets up a sheet 'ColourRamp' in the active workbook with the default colours, which can just be extended or deleted with just a few cells, so saving the user time. The add-in was developed entirely within the Excel VBA IDE by Tim Lund. He is kindly distributing the tool for free on the Datastore but suggests that users who find the tool useful make a donation to the Shelter charity. It is not intended to keep the actively maintained, but if any users or developers would like to add more features, email the author. Acknowledgments Calculation of Excel freeform shapes from latitudes and longitudes is done using calculations from the Ordnance Survey.

TwitterSee the 2019 strategic noise mapping data.
Defra has published strategic noise map data that give a snapshot of the estimated noise from major road and rail sources across England in 2012. The data was developed as part of implementing the http://ec.europa.eu/environment/noise/directive_en.htm">Environmental Noise Directive.
This publication explains which noise sources were included in 2012 strategic noise mapping process. It provides summary maps for major road and rail sources and provides links to the detailed Geographic Information Systems (GIS) noise datasets.
This data will help transport authorities to better identify and prioritise relevant local action on noise. It will also be useful for planners, academics and others working to assess noise and its impacts.
We’ve already published data which shows the estimated number of people affected by noise from road traffic, railway and industrial sources.

The LIDAR Composite DTM (Digital Terrain Model) is a raster elevation model covering ~99% of England at 1m spatial resolution. The DTM (Digital Terrain Model) is produced from the last or only laser pulse returned to the sensor. We remove surface objects from the Digital Surface Model (DSM), using bespoke algorithms and manual editing of the data, to produce a terrain model of just the surface.
Produced by the Environment Agency in 2022, the DTM is derived from a combination of our Time Stamped archive and National LIDAR Programme surveys, which have been merged and re-sampled to give the best possible coverage. Where repeat surveys have been undertaken the newest, best resolution data is used. Where data was resampled a bilinear interpolation was used before being merged.
The 2022 LIDAR Composite contains surveys undertaken between 6th June 2000 and 2nd April 2022. Please refer to the metadata index catalgoues which show for any location which survey was used in the production of the LIDAR composite.
The data is available to download as GeoTiff rasters in 5km tiles aligned to the OS National grid. The data is presented in metres, referenced to Ordinance Survey Newlyn and using the OSTN’15 transformation method. All individual LIDAR surveys going into the production of the composite had a vertical accuracy of +/-15cm RMSE.

TwitterThe Access Network Map of England
is a national composite dataset of Access layers, showing analysis of extent of
Access provision for each Lower Super Output Area (LSOA), as a percentage or
area coverage of access in England. The ‘Access Network Map’ was developed by
Natural England to inform its work to improve opportunities for people to enjoy
the natural environment. This map shows, across England, the
relative abundance of accessible land in relation to where people
live. Due to issues explained below, the map does not, and cannot, provide
a definitive statement of where intervention is necessary. Rather,
it should be used to identify areas of interest which require further

they are most wanted. Access Network Maps help support this work by
providing means to assess the amount of accessible land available in relation

access provision into a single dataset and relate this to population.
This provides a common foundation for regional and national teams to use when

point data only Due to the quantity and complexity of data
used, it is not possible to display clearly on a single map the precise
boundary of accessible land for all areas. We therefore selected a
unit which would be clearly visible at a variety of scales and calculated the
total area (in hectares) of accessible land in each. The units we
selected are ‘Lower Super Output Areas’ (LSOAs), which represent where
approximately 1,500 people live based on postcode. To calculate the
total area of accessible land for each we gave the linear routes a notional
width of 3 metres so they could be measured in hectares. We then
combined together all the datasets and calculated the total hectares of
accessible land in each LSOA. For further information about this data see the following links:Access Network Mapping GuidanceAccess Network Mapping Metadata Full metadata can be viewed on data.gov.uk.
