Sierra Water Workgroup has created these data layers to support the Tahoe-Sierra IRWM Project Data Management Application. Data used to create these layers were largely sourced from the CA DWR, USGS, National Hydrography Database, The Nature Conservancy, USBR, USDA Forest Service, USDA, USFS, CalEPA, and the Sierra Nevada DDS. Data layers were created by Kate Gladstein of the Sierra Water Workgroup.

Jurisdictional Dams: Sierra Water Workgroup has modified this layer of Jurisdictional Dams within the Tahoe Sierra Integrated Regional Water Management Area. Data was provided by the CA Department of Water Resources. Additional Information.

Nonearthen Shores: Sierra Water Workgroup has modified this layer displaying "nonearthen shores" within the Tahoe Sierra Integrated Regional Water Management Area. Data was provided by the National Hydrography Database, a collaborative entity between DWR and the US Bureau of Reclamation. From NHD: "The National Hydrography Dataset (NHD) is a feature-based database that interconnects and uniquely identifies the stream segments or reaches that make up the nation's surface water drainage system. NHD data was originally developed at 1:100,000-scale and exists at that scale for the whole country. This high-resolution NHD, generally developed at 1:24,000/1:12,000 scale, adds detail to the original 1:100,000-scale NHD. (Data for Alaska, Puerto Rico and the Virgin Islands was developed at high-resolution, not 1:100,000 scale.) Local resolution NHD is being developed where partners and data exist. The NHD contains reach codes for networked features, flow direction, names, and centerline representations for areal water bodies. Reaches are also defined on waterbodies and the approximate shorelines of the Great Lakes, the Atlantic and Pacific Oceans and the Gulf of Mexico. The NHD also incorporates the National Spatial Data Infrastructure framework criteria established by the Federal Geographic Data Committee." Original metadata.

Wetlands: The Sierra Water Workgroup modified this layer displaying wetland areas within the Tahoe Sierra Integrated Regional Water Management Boundaries. This data set represents the extent, approximate location and type of wetlands and deepwater habitats in the conterminous United States. These data delineate the areal extent of wetlands and surface waters as defined by Cowardin et al. (1979). Certain wetland habitats are excluded from the National mapping program because of the limitations of aerial imagery as the primary data source used to detect wetlands. These habitats include seagrasses or submerged aquatic vegetation that are found in the intertidal and subtidal zones of estuaries and near shore coastal waters. Some deepwater reef communities (coral or tuberficid worm reefs) have also been excluded from the inventory. These habitats, because of their depth, go undetected by aerial imagery. By policy, the Service also excludes certain types of "farmed wetlands" as may be defined by the Food Security Act or that do not coincide with the Cowardin et al. definition. Contact the Service's Regional Wetland Coordinator for additional information on what types of farmed wetlands are included on wetland maps.

Streams: Sierra Water Workgroup has produced this layer displaying flowlines of both streams and canals, within the Tahoe Sierra Integrated Regional Water Management Area. Data was provided by the National Hydrography Database, a collaborative entity between DWR and the US Bureau of Reclamation. From NHD: "The National Hydrography Dataset (NHD) is a feature-based database that interconnects and uniquely identifies the stream segments or reaches that make up the nation's surface water drainage system. NHD data was originally developed at 1:100,000-scale and exists at that scale for the whole country.

Reaches are also defined on waterbodies and the approximate shorelines of the Great Lakes, the Atlantic and Pacific Oceans and the Gulf of Mexico. The NHD also incorporates the National Spatial Data Infrastructure framework criteria established by the Federal Geographic Data Committee." Original metadata.Critical Aquatic Refuges: Sierra Water Workgroup has created this layer of critical aquatic ecosystem refuges. USDA-originated data was provided to SWWG by the ecological forecasting team Sierra Nevada DSS. From USDA FS: "This polygon layer consists of Critical Aquatic Reguges (CARs) found in the Sierra Nevada. This data was developed by the USDA Forest Service for use in the Sierra Nevada Fores Plan Amendment. Critical aquatic refuges provide habitat for native fish, amphibian and aquatic invertebrate populations." Original metadata.

HUC-12 Watersheds Boundaries: Sierra Water Work Group has modified this layer showing HUC-12 watershed boundaries outside the Tahoe-Sierra IRWM. Watershed Boundary data for this was provided by the USGS National Watershed Boundary Dataset (WBD). From USGS: “WBD provides a uniquely identified and uniform method of subdividing large drainage areas. The data is intended to be used as a tool for water-resource management and planning activities, particularly for site-specific and localized studies requiring a level of detail provided by large-scale map information. The Watershed Boundary Dataset (WBD) defines the areal extent of surface water drainage to a point, accounting for all land and surface areas. Watershed Boundaries are determined solely upon science-based hydrologic principles, not favoring any administrative boundaries or special projects, nor particular program or agency. The intent of defining Hydrologic Units (HU) for the Watershed Boundary Dataset is to establish a baseline drainage boundary framework, accounting for all land and surface areas. At a minimum, the WBD is being delineated and georeferenced to the USGS 1:24,000 scale topographic base map meeting National Map Accuracy Standards (NMAS). Hydrologic units are given a Hydrologic Unit Code (HUC). For example, a hydrologic region has a 2-digit HUC. A HUC describes where the unit is in the country and the level of the unit. The document "Federal Standards and Procedures for the National Watershed Boundary Dataset (WBD)" can be found here. ‘A hydrologic unit is a drainage area delineated to nest in a multi-level, hierarchical drainage system. Its boundaries are defined by hydrographic and topographic criteria that delineate an area of land upstream from a specific point on a river, stream or similar surface waters. A hydrologic unit can accept surface water directly from upstream drainage areas, and indirectly from associated surface areas such as remnant, non-contributing, and diversions to form a drainage area with single or multiple outlet points. Hydrologic units are only synonymous with classic watersheds when their boundaries include all the source area contributing surface water to a single defined outlet point.’” Original metadata.Private Water Districts: Sierra Water Workgroup has modified this layer of private water district boundaries in the Tahoe-Sierra Watershed Region. The Private Water District boundaries database is cooperatively shared between the U.S. Bureau of Reclamation (USBR), Mid-Pacific regional office (MP), MPGIS Service Center and the California Department of Water Resources (DWR). The USBR maintains this database with the voluntary assistance of the Private Water Districts. Original metadata. Montane Meadow Vegetation: The Sierra Water Workgroup modified this layer displaying meadow vegetation within the Tahoe Sierra Integrated Regional Water Management Boundaries. From USDA: "Data for this layer was developed by the USDA Forest Service for use in the Sierra Nevada Forest Plan Amendment Environmental Impact Statement. This layer depicts montane meadow vegetation on National Forests in the Sierra Nevada range. Meadows are wet and dry grassland types and short emergent meadow types maintained by man-made dams. Vegetation consists of a mixture of grasses, perennial herbs, rushes, and sedges. Woody vegetation is typically associated with riparian meadows. Riparian vegetation can be shrub or tree form, such as willow, alder, cottonwood, and aspen types. Meadow types are coded as wet or dry, with or without woody vegetation, or short emergent wetland. Meadow polygons are mapped to a minimum of 5 acres. California Vegetation (CALVEG) types within a meadow polygon are mapped to a minimum of 2.5 acres." Original Metadata.

Wells, Springs, Waterfalls, Gage Stations: Sierra Water Workgroup has modified this layer of hydrographic points within the Tahoe Sierra Integrated Regional Water Management Area. Data was provided by the National Hydrography Database, a collaborative entity between DWR and the US Bureau of Reclamation. From NHD: "The National Hydrography Dataset (NHD) is a feature-based database that interconnects and uniquely identifies the stream segments or reaches that make up the nation's surface water drainage system. NHD data was originally developed at 1:100,000-scale and exists at that scale for the whole country.

The GIS boundary for the Proposed Thompson Divide Withdrawal that will reserve the identified Federal lands and mineral interest from operation of the public land laws, mining laws, and mineral leasing, mineral materials, and geothermal leasing laws for up to 20 years to protect wildlife, recreation, ecological and scenic values, as described in Federal Register Notice 2022-22448 Vol. 87 No. 199 page 62878. Edits to the boundary have been incorporated from the US Forest Service and from the Bureau of Land Management in order to follow features that allow for legal land descriptions to be generated and eliminate the need for a new cadastral survey. All US Forest Service edits were made with direction USFS land managers from the White River National Forest and the Grand Mesa, Uncompahgre, and Gunnison National Forest. The Greater Thompson Divide withdraws 221,898.23 acres, including approximately 197,744.66 acres of National Forest System lands, approximately 15,464.99 acres of BLM-managed public lands, and approximately 8,688.58 acres of reserved Federal mineral interest, from all forms of entry, appropriation, and disposal under the public land laws; location and entry under the mining laws; and operation of the mineral leasing, mineral materials, and geothermal leasing laws, subject to valid existing rights, for a period of 20 years. The areas described, including both Federal and non-Federal lands, aggregate approximately 257,439.93 acres. Please refer to the Public Land Order (https://www.federalregister.gov:443/documents/2024/04/08/2024-07384/public-land-order-no-7939-thompson-divide-withdrawal-colorado) PLO No. 7939 for more information on the legal land description of the boundary.

This digital data set defines the boundary of the area contributing ground-water flow to the Death Valley regional ground-water flow-system (DVRFS) model domain. The boundary encompasses an approximate 112,000 square-kilometer region and was based on a map of regional potential developed by Bedinger and Harrill (2004). Where possible, the amount of lateral flow across the segments of the DVRFS model boundary from (or to) the contributing area was estimated from ground-water budgets of hydrologic units in the adjacent subregion (see "Larger Work Citation", Appendix 2). The lateral ground-water flow estimates were used to support development of the transient ground-water model of the DVRFS completed in 2004 by the USGS (see "Larger Work Citation", Chapter F).

The Geological Survey of Northern Ireland (GSNI) was commissioned to produce a Northern Ireland wide coastal geological dataset, detailing the bedrock geology.GSNI used the 1;10,000 digital bedrock geology map to create a coastal dataset which extends inland 200 meters and out to a seaward depth of approx. 10 metres, matching the extend of the Northern Ireland 3-Dimensional Coastal Survey. This involved refinement of the existing 1;10,000 map where signification coastal change has occurred since the original survey. Where gaps existed, unpublished datasets were used.

The New York State Coastal Management Program has established statewide boundaries in accordance with the requirements of the Coastal Zone Management Act of 1972, as amended, and its subsequently issued rules and regulations. The Coastal Map provides an estimation of the official New York State Coastal Area Boundary as defined in Section II of the New York State Coastal Management Program and Final Environmental Impact Statement (CMP FEIS). The coastal boundary was originally created as a set of maps at a scale of 1:48000. This digital representation has been created from the original paper copies through "heads-up" digitizing using geographic information software and the digital NYSDOT planimetric quadrangles at a scale of 1:24000. The official coastal boundary is a written description contained in the federally approved New York State Coastal Management Program, LIS CMP, and applicable LWRPs. The waterward boundary extends 3 miles into open ocean, to shared state lines in Long Island Sound and the New York Bight and to the International boundary in the Great Lakes, Niagara and St. Lawrence Rivers. Generally, the inland boundary is approximately 1,000 feet from the shoreline following well-defined features such as roads, railroads or shorelines as described in the CMP FEIS, unless otherwise indicated. Where necessary this boundary extends inland to include major state owned lands and facilities and electic power generation facilities which abut on the shoreline, major coastal recreational areas, significant agricultural lands, significant coastal habitats, scenic viewsheds of State or national significance, major historic or coastal dependent industrial areas, and the 100 year flood plain. In urbanized and other developed locations along the coast, the landward boundary is approximately 500 feet from the shoreline or less than 500 feet at locations where a major roadway or railway line runs parallel to the shoreline. The seaward boundary of New York State's coastal area includes all coastal waters within its territorial jurisdiction.View Dataset on the Gateway

Watershed boundary delineated for Canada-BC hydrometric stations. Currently, watersheds were delineated using 1:50,000 scale boundaries in 1996, and many watersheds encompass entire drainages, instead of just the upstream watersheds. Note - Not yet available, but we are in the process of generating BC hydrometric station upstream watersheds using updated base data, using the following method: Within BC, watershed boundaries are based on the 1:20,000-scale Freshwater Atlas fundamental watersheds, and trimmed using the BC TRIM DEM used to approximate the height-of-land at the station locations. Outside of BC, but within Canada, watershed boundaries were approximated using Canada CDED DEM data for delineation (no "stream burning" was used) and some manual editing of boundaries was done to approximately match hydrology data after the fact. Within U.S.A., the USGS Watershed Boundary Dataset was used (at the best scale available for each drainage) to delineate the watershed boundary, with the watershed trimmed using the USGS National Elevation Dataset to approximate the height-of-land when necessary.

Theses polygons represent the approximate extent of contamination for Vapor Intrusion facilities. Polygons for non-Federal Facility sites were updated in January, 2007 for the Superfund Work Load Models project. Each polygon was approved by the site RPM. Where available, the majority of these polygons represent the surface expression of the extent of the contamination. All Federal Facilities are represented by the facility boundary.

This data shows the approximate boundaries of solid waste sites (landfills) based on records of the ADEC Solid Waste Program and available imagery.

Oregon Parks and Recreation Department (OPRD) has made significant efforts to ensure the accuracy of the 6f boundary, however, 6f boundaries shown are approximate. 6f boundaries are only updated periodically and may not reflect new grants, conversions or boundary changes. Anomalies in street representation and file map accuracy can and do occur. Boundaries should be verified with OPRD Land and Water Conservation Fund Grant Program staff.Oregon LWCF Grant Website

This vector data set delineates the approximate boundary of the Eagle River watershed valley-fill aquifer (ERWVFA). This data set was developed by a cooperative project between the U.S. Geological Survey, Eagle County, the Eagle River Water and Sanitation District, the Town of Eagle, the Town of Gypsum, and the Upper Eagle Regional Water Authority. This project was designed to evaluate potential land-development effects on groundwater and surface-water resources so that informed land-use and water management decisions can be made. The boundary of the ERWVFA was developed by combining information from two data sources. The first data source was a 1:250,000-scale geologic map of the Leadville quadrangle developed by Day and others (1999). The location of Quaternary sediments was used as a first approximation of the ERWVFA. The boundary of the ERWVFA was further refined by overlaying the geologic map with Digital Raster Graphic (DRG) scanned images of 1:24,000 topographic map ...

Approximately 70%–75% of people worldwide have no formally registered land rights. Fit-For-Purpose Land Administration was introduced to address this problem and focuses on delineating visible cadastral boundaries from earth observation imagery. Recent studies have shown the potential of deep learning models to extract these visible cadastral boundaries automatically. However, studies are limited by the small size and geographical coverage of available datasets and by the lack of information about which cadastral boundaries are visible, i.e., associated with a physical object boundary. To overcome these problems, we present CadastreVision, a benchmark dataset containing cadastral reference data and corresponding multi-resolution earth observation imagery from The Netherlands, with a spatial resolution ranging from 0.1 m to 10 m. The ratio between visible and non-visible cadastral boundaries is essential to evaluate the potential automation level in cadastral boundary extraction from earth observation images and interpret results obtained by deep learning models. We investigate this ratio using a novel analysis pipeline that overlays cadastral reference data with visible topographic object boundaries. Our results show that approximately 72% of the total length of cadastral boundaries in The Netherlands are visible. CadastreVision will enable new developments in cadastral boundary delineation and future endeavours to investigate knowledge transfer to data-scarce areas

The Small Area Boundaries were created with the following credentials. National boundary dataset. Consistent sub-divisions of an ED. Created not to cross some natural features. Defined area with a minimum number of GeoDirectory building address points. Defined area initially created with minimum of 65 – approx. average of around 90 residential address points. Generated using two bespoke algorithms which incorporated the ED and Townland boundaries, ortho-photography, large scale vector data and GeoDirectory data. Before the 2011 census they were split in relation to motorways and dual carriageways. After the census some boundaries were merged and other divided to maintain privacy of the residential area occupants. They are available as generalised and non generalised boundary sets in the ITM projection.This dataset is provided by Tailte Éireann
