Enhanced Absolute and Relative Radiometric Calibration for Digital Aerial Cameras
A new laboratory radiometric calibration process has been developed at Intergraph Z/I Imaging and is being implemented for both the DMC and RMK-D camera systems. This new capability enables the development of absolutely radiometrically calibrated products for scientific and remote sensing applications and improves general image color quality and color balance. Although many advanced CCD-based m...
متن کاملSensor Correction and Radiometric Calibration of a 6-band Multispectral Imaging Sensor for Uav Remote Sensing
The increased availability of unmanned aerial vehicles (UAVs) has resulted in their frequent adoption for a growing range of remote sensing tasks which include precision agriculture, vegetation surveying and fine-scale topographic mapping. The development and utilisation of UAV platforms requires broad technical skills covering the three major facets of remote sensing: data acquisition, data po...
متن کاملRadiometric Calibration Concept of Imaging Spectrometers for a Long-term Ecological Remote Sensing Project
The National Ecological Observatory Network (NEON), funded by the National Science Foundation, is a continental-scale ecological observation platform for discovering, understanding and forecasting the impacts of climate change, land-use change, and invasive species on ecology. An imaging spectrometer will be used by the NEON Airborne Observation Platform (AOP) to observe both the human drivers ...
متن کاملLandsat-7 ETM+ Radiometric Stability and Absolute Calibration
Launched in April 1999, the Landsat-7 ETM+ instrument is in its fourth year of operation. The quality of the acquired calibrated imagery continues to be high, especially with respect to its three most important radiometric performance parameters: reflective band instrument stability to better than ±1%, reflective band absolute calibration to better than ±5%, and thermal band absolute calibratio...
متن کاملGround-look Radiometric Calibration Approaches for Remote Sensing Imagers in the Solar Reflective
Since the early 1990s, the availability of remote sensing imagery in the solar reflective (400 to 2500 nm) has seen a dramatic increase. Airborneand satellite-based sensors now cover this spectral range with a variety of spectral resolutions (from the multispectral to hyperspectral) and spatial resolutions ranging from better than 0.3 m for some airborne systems (and better than 1 m for satelli...
