Quantifying Multi-Decadal Change of Planted Forest Cover Using Airborne LiDAR and Landsat Imagery
Continuous monitoring of forest cover condition is key to understanding the carbon dynamics of forest ecosystems. This paper addresses how to integrate single-year airborne LiDAR and time-series Landsat imagery to derive forest cover change information. LiDAR data were used to extract forest cover at the sub-pixel level of Landsat for a single year, and the Landtrendr algorithm was applied to L...
متن کاملFusion of Optical and Terrestrial Laser Scanner Data
Optical imagery and range data can be registered to create photo-realistic scene models via texture mapping. Presented in this paper is an alternative approach where true colour (RBG) point clouds are generated by automatically fusing a close-range optical (RGB) image acquired with an uncalibrated digital camera with the corresponding high-density 3D lidar point cloud collected with a terrestri...
متن کاملPREDICTING FOREST HEIGHT FROM IKONOS, LANDSAT AND LiDAR IMAGERY
This paper compares and contrasts predictions of forest height in Sitka spruce (Picea sitchensis) plantations based on mediumresolution Landsat ETM+, high-resolution IKONOS satellite imagery and airborne Light Detection And Ranging (LiDAR) data. The relationship between field-measured height and LiDAR height is linear and highly significant (R 0.98) and so LiDAR height measurements were used to...
متن کاملEffects of Landsat 5 Thematic Mapper and Landsat 7 EnhancedThematic Mapper Plus radiometric and geometric calibrations andcorrections on landscape characterization
The Thematic Mapper (TM) instruments onboard Landsats 4 and 5 provide high-quality imagery appropriate for many different applications, including land cover mapping, landscape ecology, and change detection. Precise calibration was considered to be critical to the success of the Landsat 7 mission and, thus, issues of calibration were given high priority during the development of the Enhanced The...
متن کاملOn-Orbit Geometric Calibration Model and Its Applications for High-Resolution Optical Satellite Imagery
On-orbit geometric calibration is a key technology to guarantee the geometric quality of high-resolution optical satellite imagery. In this paper, we present an approach for the on-orbit geometric calibration of high-resolution optical satellite imagery, focusing on two core problems: constructing an on-orbit geometric calibration model and proposing a robust calculation method. First, a rigoro...
