  2. GIS and hydrology - Wikipedia

    en.wikipedia.org/wiki/GIS_and_hydrology

    The use of GIS to analyze groundwater falls into the field of hydrogeology. Since 98% of available freshwater on Earth is groundwater, [7] the need to effectively model and manage these resources is apparent. As the demand for groundwater continues to increase with the world’s growing population, it is vital that these resources be properly ...

  4. Groundwater model - Wikipedia

    en.wikipedia.org/wiki/Groundwater_model

    The applicability of a groundwater model to a real situation depends on the accuracy of the input data and the parameters. Determination of these requires considerable study, like collection of hydrological data ( rainfall , evapotranspiration , irrigation , drainage ) and determination of the parameters mentioned before including pumping tests .

    The dataset primarily maps features a 1:24,000-scale, but in certain areas provides detail at 1:5,000-scale. A version of the NHD called the NHDPlus is integrated with elevation and other landscape data to create detailed drainage catchments and flow volume and velocity estimates for streams and rivers of the U.S. at 1:100,000-scale.

    en.wikipedia.org/wiki/Geovisualization

    Geovisualization is closely related to other visualization fields, such as scientific visualization [1] and information visualization. [2] Owing to its roots in cartography, geovisualization contributes to these other fields by way of the map metaphor, which "has been widely used to visualize non-geographic information in the domains of information visualization and domain knowledge ...
