Belitz et. al 2019 horizontal and vertical distances to streams

Horizontal and vertical distances to the stream networks published by Belitz et al. (2019). This 30m resolution dataset served as input for estimating both static and transient water table depths across the contiguous United States (CONUS) at a 1-arcsec resolution.

Dataset Name: belitz_2019

Data Source: belitz_2019

Data Collection or Processing Notes:

The stream networks for the CONUS were determined based on the 30m resolution lateral position (LP) datasets for nine hydrologic orders generated by Belitz et al (2019), where LP=0 indicates that the grid cell is located along a stream. The horizontal distance to stream represents the closest linear distance to stream, calculated using the stream network data over the CONUS and the GDAL Proximity (raster distance) algorithm in QGIS 3.32. The vertical distance to stream is the vertical distance to the interpolated stream network, computed as the difference between the actual elevation and the interpolated stream network base level elevation.
