In WaterGAP, modeling of water use refers to computation of water withdrawals (abstractions) from either groundwater or surface water bodies (lakes, reservoirs and rivers), of consumptive water uses (the fraction of the abstracted water that evapotranspires during use) and of the return flows to groundwater or surface water bodies.
Main sectors, as defined by ISIC standards, include agriculture; forestry and fishing; manufacturing; electricity industry; and services. This indicator is also known as water withdrawal intensity. [4] According to Food and Agriculture Organization, ″total freshwater withdrawal is the sum of surface water withdrawal and groundwater withdrawal ...
The NHD is used to represent surface water on maps and is also used to perform geospatial analysis. It is a digital vector geospatial dataset designed for use in geographic information systems (GIS) to analyze the flow of water throughout the nation. The dataset represents over 7.5-million miles of streams/rivers and 6.5-million lake/ponds.

Past and Present Agricultural Land Use: Multiple datasets showing agricultural land use dating from 1700 to 2007 for 175 crops. Historic Croplands Dataset, 1700-1992: Documents historical changes in global land cover: croplands from 1700 to ...
Nonresidential water use is a volumetric measure of the use of publicly-supplied (municipal) water for areas other than residential use. It is typically subcategorized under users including Commercial, Industrial, and Institutional sub-sectors, which are often jointly designated as the ICI or CII sector.
Infographic of water footprints around the world. A water footprint shows the extent of water use in relation to consumption by people. [1] The water footprint of an individual, community, or business is defined as the total volume of fresh water used to produce the goods and services consumed by the individual or community or produced by the business.
Demo map showing high-resolution SWBD coastlines. The SRTM Water Body Data (SWBD) is a geographical dataset (2003) encoding high-resolution worldwide coastline outlines in a vector format, published by NASA and designed for use in geographic information systems and mapping applications.
The datasets are classified, based on the licenses, as Open data and Non-Open data. The datasets from various governmental-bodies are presented in List of open government data sites. The datasets are ported on open data portals. They are made available for searching, depositing and accessing through interfaces like Open API. The datasets are ...
