The dataset encompasses portions of Northern Oregon, Eastern Washington, Northern Idaho, and Northwestern Montana within the Columbia River drainage. The bare earth digital elevation models (DEM) represent the earth's surface with all vegetation and human-made structures removed. The bare earth DEMs were derived from LiDAR data using TIN processing of the ground point returns. The DEM grid cell size is 1 m. The elevation units are in meters. Some elevation values have been interpolated across areas in the ground model where there is no elevation data (e.g. over dense vegetation). Breaklines derived from lidargrammetry were used to enforce water boundaries and interpolate some areas where the ground was obscured from the LiDAR data. Water surfaces were derived from a TIN of the 3-D water edge breaklines. Watershed Sciences, Inc. collected the LiDAR and created this data set for David C. Smith & Associates, Inc. and the U.S. Army Corps of Engineers

Mount Adams, also known by the Native American names "Klickitat" or "Pahto", is a 3,742 meter-tall (12,278 feet) stratovolcano located 53 km (33 miles) north of the Columbia river straddling the borders of Skamania County, Yakima County and the Yakama Nation Reservation. Mount Adams lies in the middle of the Mount Adams volcanic field—a 1,250 square kilometer area (about 480 square miles) comprising at least 120, mostly basaltic volcanoes that form spatter and scoria cones, shield volcanoes, and some extensive lava flows. The volcanic field has been active for at least the past one million years. Mount Adams was active from about 520,000 to about 1,000 years ago and has erupted mostly andesite. Eruptions have occurred from ten vents since the last period of glaciation about 15,000 years ago. The volcano has produced a larger volume (about 300 cubic kilometers or 70 cubic miles) of eruptive material during the past million years than any other Cascade stratovolcano, surpassed only by Mount Shasta (about 350 cubic kilometers or 85 cubic miles). Approximately 6,000 and 300 years ago, debris avalanches from the southwest face of Mount Adams generated clay-rich lahars that swept more than 30 square kilometers (11 square miles) south of the volcano along the White Salmon River. The summit of Mount Adams contains a large section of unstable, hydrothermally-altered rock that can spawn future debris avalanches and lahars. This DEM (digital elevation model) represents the ground surface beneath forest cover of Mount Adams and adjacent vicinity. It is the product of high-precision airborne lidar (Light Detection and Ranging) surveys conducted during August and September of 2016 by Quantum Spatial under contract with the USGS; total area is 2278.6 square kilometers (879.8 square miles). This release consists of DEM and corresponding hillshade rasters. The survey area is divided into four sections: adams_edifice.tif, adams_indian_heaven.tif, adams_west.tif, and adams_east.tif. Hillshade images are spatially coincident to the DEM from which they are derived. Filenames appended with the suffix “_hs” indicate hillshade images (e.g. adams_edifice_hs.tif).

Mount Rainier is a designated National Register Historic District. This dataset shows historical sites within Mount Rainier designated by Prince George's County, as well as sites designated by the National Register of Historical Places.

The Oregon Department of Geology & Mineral Industries (DOGAMI) contracted with Watershed Sciences, Inc. to collect high resolution topographic LiDAR data for multiple areas within the State of Oregon. The areas for LiDAR collection have been designed as part of a collaborative effort of state, federal, and local agencies in order to meet a wide range of project goals. This LiDAR data set was collected between May 3, 2008 and April 25, 2009 and encompasses portions of the following counties in southwest Oregon- Coos, Curry, Lane, and Douglas. This data set consists of bare earth and unclassified points. There are approximately 8 points per square meter over terrestrial surfaces. In some areas of heavy vegetation or forest cover, there may be relatively few ground points in the LiDAR data. Elevation values for open water surfaces are not valid elevation values because few LiDAR points are returned from water surfaces. LiDAR intensity values were also collected.

These raster datasets are 3-meter lidar-derived images of Monroe County, West Virginia, and were created using geographic information systems (GIS) software. Lidar-derived elevation data acquired in late December of 2016 were used to create a 3-meter resolution working digital elevation model (DEM), from which a hillshade was applied and a topographic position index (TPI) raster was calculated. These two rasters were uploaded into GlobalMapper, where the TPI raster was made partially transparent and overlaid the hillshade DEM. The resulting image was exported to create a 3-meter resolution lidar-derived image. The data is projected in North America Datum (NAD) 1983 UTM Zone 17.

This dataset includes spatial locations where surface water presence observations were collected during the late summer baseflow period in Mt. Rainier National Park and surrounding area in Washington State, July 2018 - September 2020. Stream flow status (continuous flow, discontinuous flow, and dry) were recorded using the FLOwPER (FLOw PERmanence) field survey available in the Survey 123 and S1 mobile application for observations collected in 2019 and 2020. Observations collected in 2018 used an earlier version of the FLOwPER survey. Additional information to describe the field conditions are included as part of the survey. The observations were processed to correspond to pixels on the medium resolution National Hydrography Dataset (NHD) channel network stream grid and assessed for accuracy.

Elevation data, as defined in FEMA's Guidelines and Standards for Flood Risk Analysis and Mapping, describe the digital topographic data that were used to create the data representing the terrain environment of a watershed and/or floodplain. Elevation data requirements allow for flexibility in the types of information used to produce final levation deliverables. Submission of the terrain data sources allows FEMA to account for the origins of the flood study terrain data. (Source: FEMA Guidelines and Standards for Flood Risk Analysis and Mapping.)
