schematic - this graphic depicts an airborne lidar system, a remote sensing detection system that uses light from a laser. The quick light pulses measure the distance from the plane to the surface and back. GPS is used to help pinpoint location and time for greater accuracy.
map - the seamless 1-meter Digital Elevation Model (DEM) for the Lower Androscoggin watershed in Maine, produced by scientists at NGTOC and EROS. Elevations run from low elevation in light blue on up to tan, green, yellow, red and finally gray/white. The lowest point in the watershed is -.109777 meters, and the highest is 1,916.04 meters.

This photo was taken at USGS gaging station 01055000 on the Swift River near Roxbury, Maine. The falls is most commonly referred to as Swift River Falls and has many potholes and scours that demonstrate the impressive ability of water to errode rock.

screen shot - 3DEP LiDAR Explorer - Santiam River, OR's topobathy dataset(s)
imagery - Topobathymetric digital elevation model of the Santiam River in the Willamette Valley southeast of Salem, Oregon. The trees and dry land are shown as a lidar point cloud colored based on aerial imagery.
drone photo - oblique - The North Santiam drains from the Cascade Range and through the Willamette Valley foothills where it combines with the South Santiam before joining the Willamette River near Salem. The river in this section has numerous gravel bars and secondary channels and is flanked by agricultural lands and floodplain forests.

Integrated Topographic Corrections Improve Forest Mapping Using Landsat Imagery

“HIGHLIGHTS:
• [They] evaluated the impacts of topographic correction on forest mapping in the mountains.
• The enhanced C-correction and the physical model reduced topographic effects.
• The corrected Landsat imagery time series resulted in higher accuracy.
• Terrain information improved classification but not as much as topographic correction.
• [They] recommend using topographic correction for forest cover mapping..."

maps / images - Landsat summer (panel A) and autumn (Panel B) images (RGB: 743) for the study area. Subset region marked in black frame. Panels C-F show uncorrected (panel C), corrected summer image using the enhanced C-correction (panel D) or the physical model (panel E), and the corresponding illumination condition (F). Panels G-J show the same as panel C-F, but for the autumn image. The QA layers generated from FORCE were not applied here.
map - Forest cover classification agreement among the 18 sets of input variables. Pixels in red color were classified by all sets of input variables as coniferous, in green color as broadleaf forest, and in blue color as mixed forest. Black color indicates that no forest was predicted by any set of input variables. Two subsets A and B which are marked in white frames were zoomed in for a detailed map comparison in [another figure]
