Ocean areas are left unfilled for maximum flexibility by end users. Small-scale shaded relief was created with a single-direction hillshade from GMTED2010 global elevation data at 7.5-, 15-, and 30-arc-second resolutions, and resampled further for scales 1:18,489,298 and smaller. 3DEP shaded relief was derived with a multi-directional hillshade technique. 3DEP also contains coverage of Canada, Mexico, Central America, and the Caribbean at 30-meter (1-arc-second) resolution. Resolutions available include 1-meter, 3-meter (1/9-arc-second), 10-meter (1/3-arc-second), 30-meter (1-arc-second), and 60-meter (2-arc-second only in Alaska). 3DEP maintains a seamless dataset of best available raster elevation data, as LIDAR and as digital elevation models (DEMs), for the conterminous United States, Alaska, Hawaii, and Territorial Islands.

Due to Excel’s maximum row constraints, the files have been subset by decade. ![]() 3DEP maintains a seamless dataset of best available raster elevation data, as. The input data sets used to derive trends and PCA results are presented here in the zip file found below. Data 2010 (GMTED2010) for small scales (1:2,311,162 through 1:295,828,764). Daily mean-Q data were downloaded from the USGS’s National Water Information System on January 5, 2022, checked for completeness, and converted to cubic meters per second. 3DEP maintains a seamless dataset of best ava. ![]() The final quarter of approved 2020 data for both datasets was downloaded between January 6 and 8, 2022. The USGS Shaded Relief base map service from The National Map was created with data from the 3D Elevation Program (3DEP) for large and medium scales (1:9,028 through 1:1,155,581), and Global Multi-resolution Terrain Elevation Data 2010 (GMTED2010) for small scales (1:2,311,162 through 1:295,828,764). Spatial-raster datasets of daily P in mm were downloaded from Parameter-elevation Regressions on Independent Slopes Model (PRISM ) on March 30, 2021, and datasets of daily AT in degrees Celsius (☌) were downloaded June 22, 2021, both at a 4-square kilometer (km2) resolution for the contiguous U.S. We analyzed daily air temperature (AT), precipitation (P), and stream discharge (Q) metrics for 124 watersheds in Maryland, Virginia, and North Carolina, United States, from 1981 through 2020. Streamflow is largely controlled by climate forces, therefore it is likely sensitive to climate changes. Streams provide water for human activities and consumption in much of the world. ![]()
