Participatory mapping of small-scale fishing. Small-scale fishing effort is provided in the form of polygons, drawn by fishermen during the interviews on the standardized grid for the cartographic mapping of the answers, and later digitalized. The dataset contains information about the fishing effort in terms of fishing days (per month and per year), related gear, and targeted species.
The USGS National Hydrography Dataset (NHD) service from The National Map is a comprehensive set of digital spatial data that encodes information about naturally occurring and constructed bodies of surface water (lakes, ponds, and reservoirs), paths through which water flows (canals, ditches, streams, and rivers), and related entities such as point features (springs, wells, stream gages, and dams). The information encoded about these features includes classification and other characteristics, delineation, geographic name, position and related measures, a "reach code" through which other information can be related to the NHD, and the direction of water flow. The network of reach codes delineating water and transported material flow allows users to trace movement in upstream and downstream directions. In addition to this geographic information, the dataset contains metadata that supports the exchange of future updates and improvements to the data. The NHD is available nationwide in two seamless datasets, one based on 1:24,000 (or larger) scale and referred to as high resolution NHD, and the other based on 1:100,000 scale and referred to as medium resolution NHD. The NHD from The National Map supports many applications, such as making maps, geocoding observations, flow modeling, data maintenance, and stewardship. The NHD is commonly combined with other data themes, such as boundaries, elevation, structures, and transportation, to produce general reference base maps. The National Map download client allows free downloads of public domain NHD data in either Esri File Geodatabase or Shapefile formats. For additional information on the NHD, go to https://www.usgs.gov/national-hydrography/national-hydrography-dataset.

This data set contains small-scale base GIS data layers compiled by the National Park Service Servicewide Inventory and Monitoring Program and Water Resources Division for use in a Baseline Water Quality Data Inventory and Analysis Report that was prepared for the park. The report presents the results of surface water quality data retrievals for the park from six of the United States Environmental Protection Agency's (EPA) national databases: (1) Storage and Retrieval (STORET) water quality database management system; (2) River Reach File (RF3) Hydrography; (3) Industrial Facilities Discharges; (4) Drinking Water Supplies; (5) Water Gages; and (6) Water Impoundments. The small-scale GIS data layers were used to prepare the maps included in the report that depict the locations of water quality monitoring stations, industrial discharges, drinking intakes, water guages, and water impoundments. The data layers included in the maps (and this dataset) vary depending on availability, but generally include roads, hydrography, political boundaries, USGS 7.5' minute quadrangle outlines, hydrologic units, trails, and others as appropriate. The scales of each layer vary depending on data source but are generally 1:100,000.

This mapping GIS app displays landforms left behind by the ice sheet that covered most of Britain and Ireland during the last ice age (27,000 years ago). It contains over 170,000 landforms that have been collated from various reports published over the last 150 years.The aim of the BRITICE project is to bring together published information regarding the geomorphology (landforms) of the last British-Irish ice sheet.About: This layer comes from Britice version two, which is updated since 2004. The imprint of the last ice sheet on Britain and Ireland has been studied for over 100 years. During this time, scientists conducting fieldwork and mapping from satellite data and aerial photography produced geomorphological (landform) maps, documenting the distribution of landforms left behind by the ice sheet. We reviewed over 1,800 publications from the academic literature, British Geological Survey and Irish Geological Survey mapping.

Since 2016, corporations are increasingly getting involved in OpenStreetMap (OSM). Large corporations such as Apple, Microsoft, Meta, and Amazon have hired large teams to edit in OSM and contribute map data on a global scale. At the same time, some observers and the OSM mapping communities have expressed concerns about corporate involvement. Previous studies have been able to identify global patterns, but their small-scale effects on other non-corporate or volunteer mappers have been difficult to quantify. The presented analysis attempts to contribute to this debate by analyzing mapping trends for corporate and non-corporate contributors at two scales. First, we investigated the impact of corporate mapping on the global scale between 2016 and 2024. Corporate editors filled in the gaps left by other volunteer mapping efforts mainly in high- and medium-income countries. 36 countries accounted for 88% of all corporate mapping activity. Furthermore, our results reveal an unexpected declining number of overall corporate edits since 2021, despite an apparent increase in the number of active companies. Second, we study the impact of corporate mapping on country- and small-scale mapping. For this analysis, we considered data from the United Arab Emirates, Colombia, Vietnam, and Mexico. Despite concerns in the OSM communities, our results suggest that there seems to be no general tendency for corporate contributions to discourage non-corporate contributions. Still, given the fact that overall corporate edits have been declining, this raises the question if there is a change in the companies’ approach toward OSM. We conclude that future research needs to shed light on this shift by investigating the accompanying effects on spatial data quality and OSM community sustainability.

Abstract: 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. Use the metadata link, http://nhdgeo.usgs.gov/metadata/nhd_high.htm, for additional information. Purpose: The NHD is a national framework for assigning reach addresses to water-related entities, such as industrial discharges, drinking water supplies, fish habitat areas, wild and scenic rivers. Reach addresses establish the locations of these entities relative to one another within the NHD surface water drainage network, much like addresses on streets. Once linked to the NHD by their reach addresses, the upstream/downstream relationships of these water-related entities--and any associated information about them--can be analyzed using software tools ranging from spreadsheets to geographic information systems (GIS). GIS can also be used to combine NHD-based network analysis with other data layers, such as soils, land use and population, to help understand and display their respective effects upon one another. Furthermore, because the NHD provides a nationally consistent framework for addressing and analysis, water-related information linked to reach addresses by one organization (national, state, local) can be shared with other organizations and easily integrated into many different types of applications to the benefit of all.
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. High resolution NHD 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.) Like the 1:100,000-scale NHD, high resolution NHD contains reach codes for networked features and isolated lakes, flow direction, names, stream level, and centerline representations for areal water bodies. Reaches are also defined to represent 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 set out by the Federal Geographic Data Committee.
