The Zip folder contains a range of key GIS boundary files for ESRI and Map Info covering Greater London. The folder includes: - Output Area (OA) 2011, - Lower Super Output Area (LSOA) 2004 and 2011, - Middle Super Output Area (MSOA) 2004 and 2011, - London Wards (two files: City of London merged into single area and split into seperate wards). There are separate download file for 2014 & 2018 boundaries. - London Boroughs Note: The OA to MSOA boundaries have been generalised to reduce file size/loading time. On maps created using these boundaries the copyright must be stated. This is: "Contains National Statistics data © Crown copyright and database right [2015]" and "Contains Ordnance Survey data © Crown copyright and database right [2015]" For more information about boundary data sharing read these Terms and Conditions of Supply.

The GLA have produced a dataset that provides a more accurate estimate of the extent of the London’s green infrastructure - the city’s parks, gardens, trees, green spaces, rivers and wetlands, and features such as green roofs. The green cover layer was created by combining classified near-infrared aerial imagery (NDVI) with land use datasets and resulted in a green cover estimate for London of between 48-51 percent. The baseline is presented as a range to account for variations in the analysis of aerial imagery. The methodology is set out in the report below and a web map created to visualise the data. The final green cover layer is available to download in a geospatial format (shape files). Contains OS data © Crown copyright and database rights 2019. Contains Verisk Analytics GeoInformation Group UKMap data. NOTE: The data is based on Ordnance Survey mapping and the data is published under Ordnance Survey's 'presumption to publish'.

These data are all about the station entries/exit totals in different categories for each station in the London Underground system.

There are two types of files:

Entry/Exit Counts:

IMPORTANT:

Entry/Exit counts are daily totals, NOT annual totals. They are counts for one typical day for the whole traffic day. To get annual, apply the following weights:

Annual figures are calculated as entries plus exits, weighting weekdays by 253, Saturdays by 52 and Sundays by 59.

This weighting is based on the assumption that 7 Bank-holidays are represented by 7 Sundays and grossing up to a 364 day year excluding Christmas Day This adjustment does not change from year to year depending on when the Bank Holidays are but is used as an annual factor for comparing one year with another

Total exits for the system should equal total entries but they do not because of inaccuracies in the counts and because counts take place on different days and some counts include NR passengers.

Note Column:

N = station closed T = Figures include all passengers on the W&C line (which is closed on Sundays) B = Figures for Bank/Monument now exclude W&C line passengers interchanging with other lines A = previous year's counts adjusted by average change between years by zone

Columns:

nlc: Station ID

Station Name: Name of station

Borough: Surrounding area name

Note: Any issues with counting during year

Entry_Week: Typical weekday entry totals

Entry_Saturday: Typical Saturday entry totals

Entry_Sunday: Typical Sunday entry totals

Exit_Week: Typical weekday exit totals

Exit_Saturday: Typical Saturday exit totals

Exit_Sunday: Typical Sunday exit totals

AnnualEntryExit_Mill: Entries+Exits for entire year (in millions)

Geospatial Stations:

This is a json file I constructed for a web based visualization project a few years ago. There are three basic keys: 'stations': Station name tied to lat/lon coordinates 'lines': Coordinates of each line on the tube map. Circle, District, etc. 'river': Coordinates of the Thames river.

These are useful for drawing the map as it appears on the classic, colorful map of the London Underground.

The TFL has only updated this data through 2017. When they provide updated figures for the last 4+ years I will update them here.

This dataset is a general representation of parcel mapping used by the City of London. The mapping is derived from assessment and ownership data but is not sanctioned by either MPAC or Teranet. The geospatial accuracy is not to be relied upon and must not be used for building permit applcaitions, engineering designs, detailed planning, development or property use. Use at own risk.

Layered GeoPDF 7.5 Minute Quadrangle Map. Layers of geospatial data include orthoimagery, roads, grids, geographic names, elevation contours, hydrography, and other selected map features.

This feature service is available through CT ECO, a partnership between UConn CLEAR and CT DEEP. It is also available as a map service and a tiled map service. This dataset is a statewide service of municipal parcels (properties) including their geometry (polygon shape) and attributes (tabular information about each parcel). In order to preserve the attributes, each municipality is added individually to the service.

Transport for London's (TFL) Public Transport Accessibility Levels (PTALs)

PTALS are a detailed and accurate measure of the accessibility of a point to the public transport network, taking into account walk access time and service availability. The method is essentially a way of measuring the density of the public transport network at any location within Greater London.

Each ares is graded between 0 and 6b, where a score of 0 is very poor access to public transport, and 6b is excellent access to public transport.

The current methodology was developed in 1992, by the London Borough of Hammersmith and Fulham. The model has been thoroughly reviewed and tested, and has been agreed by the London Borough-led PTAL development group as the most appropriate for use across London.

The measure therefore reflects:

• • Walking time from the point-of interest to the public transport access points;
• • The reliability of the service modes available;
• • The number of services available within the catchment; and
• • The level of service at the public transport access points - i.e. average waiting time.

It does not consider:

• • The speed or utility of accessible services;
• • Crowding, including the ability to board services; or,
• • Ease of interchange.

The PTAL methodology was developed for London where a dense integrated public transport network means that nearly all destinations can be reached within a reasonable amount of time. Research using the ATOS (Access to Opportunities and Services) methodology shows that there is a strong correlation between PTALs and the time taken to reach key services – i.e. high PTAL areas generally have good access to services and low PTAL areas have poor access to services.

6-digit references identify 100m grid squares.

The 2012 CSV file previously available on the Datastore is now only available via the TfL feeds page.

The 2014 files are available to download below. This includes the GIS contour files.

Current PTAL values can be viewed at TfL’s web site: www.webptals.org.uk

The GLA has calculated the percentage of population for each ward, LSOA, MSOA and borough within each PTAL. The files for 2014 are available below. The method used mapped the number of addresses (using Ordinance Survey AddressBase Plus, and 2011 Census London Output Areas boundaries).

TFL also publish on their website a tool that shows travel time and PTAL maps from any point within London. Click anywhere on the map or input a postcode to change the selected location.

The Green Infrastructure Focus Map is a new tool and evidence base to help London’s decision-makers identify where green infrastructure improvements and investments might be best targeted, and what kind of interventions might be most useful for the needs of a specific area. The Green Infrastructure Focus Map can help: identify where there is more need or less need for green infrastructure interventions describe which specific environmental or social issues have the greatest need for intervention in a particular location highlight other issues that green infrastructure can’t necessarily help with, but that are useful context for decision making (e.g. income deprivation) Please contact environment@london.gov.uk with any queries or feedback. Data and analysis from GLA GIS Team form a basis for the policy and investment decisions facing the Mayor of London and the GLA group.

This database of Brownfield land replaces in more detail and accuracy the EP National Land Use Database (NLUD) for London. The current NLUD assessment covers sites in excess of 0.25ha. This project validates, checks and updates this information for existing NLUD sites plus new sites down to a smaller threshold of 0.1 hectares and above.

The Database records over 2,000 Brownfield sites across London, equivalent to more than 2% of the land in Greater London (an increase of over 1,000 sites than recorded on the previous system). The Homes and Communities Agency will use the database as their preferred platform for boroughs to record brownfield sites.

The London Database uses Geographic Information Systems (GIS) mapping. It includes transport routes, deprivation, social infrastructure, as well as heritage and natural environment assets that can be overlaid over the dataset of brownfield land. Visitors to the Database website can identify sites suitable for development, and better explore and understand a site’s context.

Download .zipThis file contains point data used for the construction of lake maps for State of Ohio. Data was collected in the Ohio State Plane Coordinate System for both the northern and southern state planes in the Lambert Projection Zone. Except for the lakes in extreme western Ohio which is in UTM zone 16N the majority of lakes are in UTM zone 17N and datum NAD83. The data was collected by fisheries biologists with the Ohio Division of Wildlife using a Trimble GPS Pathfinder Pro XRS receiver and Recon datalogger. Geocoding of depths occurred during water levels that were ± 60 cm of full recreational pool while transversing the reservoir at 100m intervals driving at a vessel speed of 2.0-2.5 m/s. Depth contour lines were derived from this data by creating a raster file from the point bathymetry and boundary lake data. The Spatial Analyst Interpolation tool outputs point data that is then changed into polyline contours using the Spatial Analyst Surface tool.
