The London Borough of Barnet is divided into 24 electoral Wards. The current warding arrangement came into effect on 5th May 2022. These maps have been created as general resource for the council. The information is sourced from Ordnance Survey Open Data products and may be used more widely subject to the Open Government Licence (v3). Each ward map is available in 2 different sizes, in pdf format and includes an approximate scale and information currency. Ward boundary information is from OS Boundary-Line™ (normally released in May and October) The A3 base map information is from OS OpenMap - Local (normally released in April and October) The A4 base map information is from OS VectorMap District (normally released in May and November) Only the latest version of the maps are published and older versions are not retained. Please note: these maps may not reflect the latest information published by Ordnance Survey, see document dates for date last updated.

This dataset contains polylines depicting non-woodland linear tree and shrub features in Cornwall and much of Devon, derived from lidar data collected by the Tellus South West project. Data from a lidar (light detection and ranging) survey of South West England was used with existing open source GIS datasets to map non-woodland linear features consisting of woody vegetation. The output dataset is the product of several steps of filtering and masking the lidar data using GIS landscape feature datasets available from the Tellus South West project (digital terrain model (DTM) and digital surface model (DSM)), the Ordnance Survey (OS VectorMap District and OpenMap Local, to remove buildings) and the Forestry Commission (Forestry Commission National Forest Inventory Great Britain 2015, to remove woodland parcels). The dataset was tiled as 20 x 20 km shapefiles, coded by the bottom-left 10 km hectad name. Ground-truthing suggests an accuracy of 73.2% for hedgerow height classes.

This layer uses data to identify the location of the total waterside resource that is more likely to be publicly accessible because it is either in proximity to a OS path (within 10m) and/or is a waterbody adjacent to Accessible Green Infrastructure (within 1m).

            The Ordnance Survey (OS) OpenMap Local 

Surface Water (polygon and line) and Tidal Water (polygon) datasets were used to define the Blue Infrastructure (BI) to which access is measured. This includes rivers, streams, lakes, reservoirs, canals and tidal waters. OS Paths data identifies urban paths that are likely to be publicly accessible, but some may not be. Access to waterside created by proximity to roads, pavements, bridges (unless they are for PRoW) and public realm (such as boulevards, shopping centres etc) is not represented in the mapping. This may result in an under representation of accessible urban waterside.

            Because the assessment method uses a 10m 

buffer around urban paths to assess likelihood of accessibility, both sides of narrow water courses may be picked up as accessible even if only one side is aligned with the path. Thus, some waterside assigned "accessible" will in fact not be accessible. This will over-estimate likely accessible waterside. The data has been taken from Natural England's GI portal.

This layer uses data to identify the location of the total waterside resource that is more likely to be publicly accessible because it is either in proximity to a Public Right of Way (within 10m) and/or is a waterbody adjacent to Accessible Green Infrastructure (within 1m).The Ordnance Survey (OS) OpenMap Local Surface Water (polygon and line) and Tidal Water (polygon) datasets were used to define the Blue Infrastructure (BI) to which access is measured. This includes rivers, streams, lakes, reservoirs, canals and tidal waters. The access to waterside layer only maps the likelihood that the edges of water bodies and course are accessible. The accessibility is created purely by proximity of water edge to publicly accessible green infrastructure and/or a Public Right of Way. Circumstances on the ground might mean that some sections marked as likely to be accessible are in fact not. The identification of waterside as accessible is thus indicative not definiteThe data has been taken from Natural England's GI portal.

This dataset comprises a range of land cover types where the woodland potential layers have been masked, owing to existing woodland, watercourses, peat, roads, rail and urban areas. Other constraints data, such as protected habitats and high grade agricultural land, should also be considered. Locations identified may have more recent land use change than available at the time of publication.The Woodland Constraints data is based on an amalgamation of the following datasets: OS Open Map Local – Roads, Rail and Woodland layers (2016); Forestry Commission Woodland Inventory (2015); OS Open Water – Lines, Areas and Rivers (2016); CORINE Land Cover Urban and Peat layers (2012).

Runoff Attenuation Features Potential is our best estimate of locations of high flow accumulation across the land surface or in smaller channels, where it may be possible to temporarily store water and attenuate flooding during high flows. The dataset is designed to support signposting of areas where to target enhanced storage. It is based upon the Risk of Flooding from Surface Water datasets and identifies areas of high flow accumulations for the 1% Annual Exceedance Probability surface water maps. The areas of ponding or accumulation are between 100 and 5000 metres squared, and have been tagged where they fall on an area of slope steeper than 6% as gully blocking opportunities. All the potential areas have been constrained so that they are not in urban areas or on roads, rails or canals.The data does not does not provide information on design, which may need to consider issues such as drain-down between flood events. It is important to note that land ownership and change to flood risk have not been considered. Locations identified may have more recent building or land use than available.A GIS tool developed by JBA, called JRAFF (JBA Runoff Attenuation Feature Finder) was used to analyse potential for Runoff Attenuation Features. This identifies areas of high flow accumulation from the Risk of Flooding from Surface Water Depth 1 percent annual chance map that could be targeted as opportunities for enhanced temporary storage. OS Terrain 50 (2016) was used to determine gully blocking potential, based on a threshold of > 6 degrees (10%). A constraint layer was applied based on CORINE Land Cover Urban layer (2012), OS Open Map Local – Roads, Rail and Building layers (2016) and OS Open Rivers – Canal layer (2016).

This is a polygon dataset showing Water Framework Directive (WFD) Lake Water Bodies, which was created to meet the requirements of the WFD. This dataset provides attribution relating to the 2019 classification results, as well as other relevant information and data about each lake water body.

Article 2, clause 5 of the WFD defines them as '…a body of standing inland surface water'.

Lake water bodies which are artificial and modified are included within this dataset. However, generally only lakes above 50 hectares are assessed under the WFD except for lakes in protected areas, where a minimum of 5.0 hectares is used. Lakes below this threshold are not included within this dataset unless allocated as Sites of Special Scientific Interest (SSSI) as supplied by Natural England. Any lake judged to be a Drinking Water Protected Area is included in this dataset.

Lake polygons are based on Ordnance Survey data from OS OpenMap - Local data.

There are three layer files associated with this dataset. There is a layer file called WFD_Lake_Water_Bodies_Cycle_3_Classification_2019_Chemical_Class.lyrx, a layer file called WFD_Lake_Water_Bodies_Cycle_3_Classification_2019_Chemical_Class_ex_uPBT.lyrx, and a layer file called WFD_Lake_Water_Bodies_Cycle_3_Classification_2019_Ecological_Class.lyrx. The layer files display the chemical status, and the ecological status or potential for each lake body. Please note that there are limitations with the shapefile format of the data. The data applies to Cycle 3 of the WFD.
