Series of 1: 100 000 scale topographic maps pubished between 1958 and 1978. Data was collated and published by War office and Air Ministry (United Kingdom) subsequently Ministry of Defence (United Kingdom)[GSGS]; Survey Kenya [SK]; Directorate of Overseas Surveys for the Kenya Government [D.O.S.] . Maps are projected using the East African Grids (Transverse Mercator(Clarke 1880); Arc (1960) (Clarke 1880). A small number of the maps are shown as using Arc (1950) (Clarke 1880) however, this dataum is usually used for map in Botswana, Malawi, Zambia and Zimbabwe. The map references for the sheets indicated to be in Arc (1950) (Clarke 1880) have been flagged to indicate this. Publishers: G.S.G.S.

Environmental Sensitivity Index (ESI) maps are an integral component in oil-spill contingency planning and assessment. They serve as a source of information in the event of an oil spill incident. ESI maps contain three types of information: shoreline habitats (classified according to their sensitivity to oiling), sensitive biological resources, and human-use resources. Most often, this information is plotted on 7.5 minute USGS quadrangles, although in the Alaska ESI maps, USGS topographic maps at scales of 1:63,360 and 1:250,000 are used, and in other ESI maps, NOAA charts have been used as the base map. Collections of these maps, grouped by state or a logical geographic area, are published as ESI atlases. Digital data have been published for most of the U.S. shoreline, including Alaska, Hawaii, and Puerto Rico.

The 1:63 360 / 1:50 000 scale map series are the most useful scale for most purposes. They provide almost complete coverage of onshore Great Britain. The BGS collection of 1:63 360 and 1:50 000 scale maps comprises two map series: - Geological Survey of England and Wales 1:63 360 / 1:50 000 Geological Map Series [New Series]. These maps are based on the Ordnance Survey One-inch New Series topographic basemaps and provide almost complete coverage of England and Wales, with the exception of sheet 180 (Knighton). The quarter-sheets of 1:63 360 Old Series sheets 91 to 110 coincide with sheets 1 to 73 of the New Series maps. These earlier maps often carry two sheet numbers which refer to the Old Series and the New Series. - Geological Survey of Scotland 1:63 360 / 1:50 000 Geological Map Series. These maps are based on the Ordnance Survey First, Second, Third and Fourth editions of the One-inch map of Scotland. The maps used the most recent topographic basemap available at the time. In the Western Isles, one-inch mapping was abandoned and replaced by maps at 1:100 000 scale, which are associated with this series. Sheets were traditionally issued at 1:63 360 scale, with the first 1:50 000 maps appearing in 1972. Sheets at 1:50 000 scale may be either facsimile enlargements of an existing 1:63 360 sheets, or may contain new geology and cartography. The latter bear the additional series designation '1:50 000 series'. Within the Scottish series, new mapping at 1:50 000 scale was split into east and west sheets. For example, the original one-inch sheet 32 became 1:50 000 sheets 32E and 32W. A number of irregular sheets were also introduced with the new 1:50 000 scale mapping. There are a number of irregular special sheets within both series. Geological maps represent a geologist's compiled interpretation of the geology of an area. A geologist will consider the data available at the time, including measurements and observations collected during field campaigns, as well as their knowledge of geological processes and the geological context to create a model of the geology of an area. This model is then fitted to a topographic basemap and drawn up at the appropriate scale, with generalization if necessary, to create a geological map, which is a representation of the geological model. Explanatory notes and vertical and horizontal cross sections may be published with the map. Geological maps may be created to show various aspects of the geology, or themes. The most common map themes held by BGS are solid (later referred to as bedrock) and drift (later referred to as superficial). These maps are, for the most part, hard-copy paper records stored in the National Geoscience Data Centre (NGDC) and are delivered as digital scans through the BGS website.

You are able to turn on and off layers and change their symbols. You can open this style in the vector tile style editor, make your changes and save a copy of your modified style to use yourself.As the GB Topographic style is designed to be used in conjunction with the GB Hillshade, it is recommended that after creating you own style you combine it in a webmap with Hillshade service.The map is based primarily on OS Zoomstack data (last updated December 2022).Please send any feedback to VectorTiles@esriuk.com

This record consists of 5 different datasets covering the Alexander Island region of Antarctica: coastline (including grounding line and ice shelf fronts), contours, spot heights, rock outcrop and lakes. The data have been produced for a new topographic map of Alexander Island at 1:500,000 scale, produced by the Mapping and Geographic Information Centre, British Antarctic Survey. The data are suitable for a 1:500,000 scale map but may be suitable for larger scales in certain areas. They have been created from source data ranging from 2022 - 2025. The data primarily cover Alexander Island, and also cover Rothschild, Charcot and Latady islands, as well as Wilkins and George VI ice shelves, and the Rymill Coast section of Palmer Land on the Antarctic Peninsula. The datasets were created using a mixture of GIS software, primarily digitised from Sentinel-2 satellite imagery or extracted from high resolution, published elevation models. Exact details of each dataset can be found in the lineage statements.

Digital data from VG07-5 Springston, G. and De Simone, D., 2007,�Surficial geologic map of the town of Williston, Vermont: Vermont Geological Survey Open-File Report VG07-5, 1 color plate, scale 1:24,000.� Data may include surficial geologic contacts, isopach contours lines, bedrock outcrop polygons, bedrock geologic contacts, hydrogeologic units and more. The surficial geologic materials data at a scale of 1:24,000 depict types of unconsolidated surficial and glacial materials overlying bedrock in Vermont. Data is created by mapping on the ground using standard geologic pace and compass techniques and/or GPS on a USGS 1:24000 topographic base map. The materials data is selected from the Vermont Geological Survey Open File Report (OFR) publication (https://dec.vermont.gov/geological-survey/publication-gis/ofr). The OFR contains more complete descriptions of map units, cross-sections, isopach maps and other information that may not be included in this digital data set.

Coastline for Antarctica created from various mapping and remote sensing sources, consisting of the following coast types: ice coastline, rock coastline, grounding line, ice shelf and front, ice rumple, and rock against ice shelf. Covering all land and ice shelves south of 60°S. Suitable for topographic mapping and analysis. High resolution versions of ADD data are suitable for scales larger than 1:1,000,000. The largest suitable scale is changeable and dependent on the region.

Major changes in v7.5 include updates to ice shelf fronts in the following regions: Seal Nunataks and Scar Inlet region, the Ronne-Filchner Ice Shelf, between the Brunt Ice Shelf and Riiser-Larsen Peninsula, the Shackleton and Conger ice shelves, and Crosson, Thwaites and Pine Island. Small areas of grounding line and ice coastlines were also updated in some of these regions as needed.

Lineage

Dataset compiled from a variety of Antarctic map and satellite image sources. The dataset was created using ArcGIS and QGIS GIS software programmes and has been checked for basic topography and geometry checks, but does not contain strict topology. Quality varies across the dataset and certain areas where high resolution source data were available are suitable for large scale maps whereas other areas are only suitable for smaller scales. Each line has attributes detailing the source which can give the user further indications of its suitability for specific uses. Attributes also give information including 'surface' (e.g. grounding line, ice coastline, ice shelf front) and revision date. Compiled from sources ranging in time from 1990s-2022 - individual lines contain exact source dates.

Complete Antarctic contour dataset, split and labelled according to whether the contour represents an ice or rock surface. Data have been prepared from various map and remotely sensed datasets. Due to the differing sources, this dataset has inconsistent intervals between contour lines. Certain regions contain very detailed contours obtained from VHR elevation models and photogrammetry work. Further information regarding source and source data can be found within the attribute table. Certain inconsistencies and errors are currently known and a comprehensive update is planned for version 7.3.
