[Fit-elevation] FW: possible new grant opportunity in 2021/2022 - Elevation Derived Hydrography Improvement

[EDWARDS Jacob * DGMI]

USGS has released new specifications for hydrography based on 3DEP lidar data: Elevation-Derived Hydrography Acquisition Specifications (usgs.gov)<https://pubs.usgs.gov/tm/11/b11/tm11b11.pdf>. Below is the first paragraph of the Background section:

In 2013, the USGS National Geospatial Program (NGP) established the 3DEP as an interagency group to produce and distribute nationwide coverage of high-resolution elevation data (derived from lidar and interferometric synthetic aperture radar [commonly known as IfSAR] sources) for the United States. In 2020, an effort is underway to improve the positional quality of the USGS NHD to be more closely aligned with the 1-m 3DEP DEMs, which are being derived from lidar and, in Alaska, the 5-m DEMs, which are being derived from IfSAR. The improved integration of elevation and hydrography.

The release of this document might indicate that USGS 3DEP will solicit grant funding applications for elevation-derived hydrography updates to the NHD.
