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.
