Mann鈥怟endall analysis was used to determine statistically significant changes in flow statistics, which were then compared to National Land Cover Dataset (NLCD) watershed land uses from 2001 and 2019. All analyzed gages had one or more flow statistics with at ...
This Mission Area also provides fundamental remote sensing science as well as data management services and produces foundational data layers including the national hydrography dataset and the National Land Cover Database. The Core Science Systems Mission Area builds and facilitates partnerships through the...
Improvement in absolute geolocation accuracy of the global ground reference dataset used in Landsat Level-1 processing. Updated global digital elevation modeling sources. Calibration and validation updates. Global Level-2 surface reflectance and surface temperature scene-based products. ...
The compiled dataset includes geomorphic, hydrologic, geologic, and land cover attributes hypothesized to influence groundwater-surface water interactions and/or the influence of groundwater discharge on surface water temperatures. The NHM groundwater attributes are used as input features to a neural ...
See below for a description of the various DEM dataset types. Since these datasets are abundant and available freely via the Internet, this converter can be put to good use for creating realistic (and accurate) 3d landscape geometry.
the building of a nationwide database of land cover, also topologically structured, but available in raster format, in the Land Use Data Analysis Program; the automation of producing graphic products including topographic maps with the Digital Cartographic Software System and the Graphic Map Production...
domains and easily modified for use with other precipitation scenarios.Developing multiple versions of a year's EAG spatially explicit abundance dataset predictions from multiple weather-based scenarios can provide important information to land managers as they prepare for variable EAG dynamics each year....
To generate the DEMs, we use the triangular irregular network (TIN) algorithm, which is a local neighborhood algorithm that represents topography as a set of neighboring triangles. The DEM’s optimal resolution is based on the point density of the point cloud dataset [45]: 𝐺𝑟𝑖𝑑 ...
