A Land Cover/Land Use (LCU) spatial database was developed based on the 2020 aerial imagery, which adds a fourth systemic-wide database to the existing 1989, 2000, and 2010/11 LCU databases. While a crosswalk was used to update the 1989 LCU database (originally developed using a different classification system), the 2000, 2010/11, and 2020 LCU databases share the same classification, making them directly comparable from a classification standpoint. Furthermore, protocols...

Categories: Data, Data Release - In Progress; Tags: Conterminous US, environment Reference Fabric Area Intersection Weights This data release contains a series of tabular crosswalks with spatial weighting for facilitating the conversion of spatial data between different hydrographic networks and spatial units. The child items in this repository contain the following types of intersections: polygon to polygon polygon to raste flowline to polygon flowline to flowline The format of these files is zipped csv contain three columns: id_source: the identifier of the polygons requiring weights. id_target: the identifer of the polygons of the target data to be intersected with the id_source. weight: (w) the fractional overlap of id_source to id_target. Additional details for each of these can be found in the metadata underneath each child...

Typically, the EAG estimates are publicly released within 7-13 days of the latest satellite observation used for that version. Each weekly release contains five fractional cover maps along with their corresponding confidence maps for: 1) a group of 16 species of EAGs, 2) cheatgrass (Bromus tectorum); 3) Field Brome (Bromus arvensis); 4) medusahead (Taeniatherum caput-medusae); and 5) Sandberg bluegrass (Poa secunda). These datasets were generated leveraging field observations from Bureau of Land Management (BLM) Assessment, Inventory,...
