Georegistration of airborne hyperspectral image data
A suite of geometric sensor and platform modeling tools has been developed which have achieved consistent subpixel accuracy in orthorectification experiments. Aircraft platforms in turbulent atmospheric conditions present unique challenges and have required creative modeling approaches. The geometric relationship between an image point and a ground object has been modeled by rigorous photogramm...
متن کاملAssessing and Correcting Topographic Effects on Forest Canopy Height Retrieval Using Airborne LiDAR Data
Topography affects forest canopy height retrieval based on airborne Light Detection and Ranging (LiDAR) data a lot. This paper proposes a method for correcting deviations caused by topography based on individual tree crown segmentation. The point cloud of an individual tree was extracted according to crown boundaries of isolated individual trees from digital orthophoto maps (DOMs). Normalized c...
متن کاملTopographic Map Updation Using Cartosat-1 Data
Indian Remote Sensing satellite Cartosat-1 was launched on 5 May 2005. It has a payload consisting of two cameras one near nadir looking (-5 deg) and the other forward looking (+26 deg) providing the real time stereo data along the track with spatial resolution of 2.5m. These cameras are mounted with a fixed geometry which helps in collecting stereo coverage of the terrain at a fixed B/H ratio ...
متن کاملAirborne mapping using LIDAR
Mapping is a central and common task in robotics research. Building an accurate map without human assistance provides several applications such as space missions, search and rescue, surveillance and can be used in dangerous areas. One application for robotic mapping is to measure changes in terrain volume. In Sweden there are over a hundred landfills that are regulated by laws that says that th...
متن کاملA Geomorphological Model for Landslide Detection Using Airborne Lidar Data
This study analyzes multi-temporal LiDAR data of high accuracy and high resolution by installing a geomorphometric model for extracting landslides. First, two sets of LiDAR data were acquired for before and after a heavy rainfall event. The landslides which took place from 2005 to 2009 were classified automatically by satellite images, and subsequently the landslides were interpreted and edited...
