we have the data, we have the people, we have the technology...
Spatial analysts at the MD-DE-DC WSC use Geographic Information Systems to interpret data collected through field reconnaissance and downloaded from internal USGS, other federal, state, and local agencies, academic institutions, industry, and other professional contracting organizations. GIS is used to analyze the data using shapefiles and geodatabased information to help prove or disprove hypotheses and enhance deliverables by visualizing the data in the form of thematic or point-referenced interactive web products so they are easily understood, we use our geospatial expertise to create products that are focused on advancing our science and meeting our cooperators’ needs.
Metadata Record: NHDPlus V2.1 Reach Catchments and Upstream Watersheds
Attributes for NHDPlus V2.1 Describing a series of data sets of natural and anthropogenic features linked to NHDPlus Version 2.1’s nearly 2.7 million stream segments, catchments, and their upstream watersheds within the conterminous United States
Average Monthly Runoff Model Over Period of Record, 1951-2000
Attributes for NHDPlus V2.1 This data set represents the average monthly runoff from McCabe and Wolock's Runoff Model 1951-2000 compiled for two spatial components of the NHDPlus version 2.1 data suite for the conterminous United States
3DEP: 2023 Three-Dimensional Elevation Program
To respond to growing needs for high-quality elevation data, the goal of 3DEP is to complete acquisition of nationwide lidar by 2023 to provide the first-ever national baseline of consistent high-resolution topographic elevation data.
