In this paper, extraction of the forest tree height based on LiDAR (Light Detection and Ranging) data was studied. A simple algorithm was proposed to compensate the result computed by the DEMs of first return and last return. The satellite image download from the GoogleEarth was used to facilitate the analysis. The algorithm was tested with these data, and had been proved to be effective. Although...
This paper addressed the planning and scheduling problem for earth observing satellites fleet of China. The author first described the problem scope naturally, then proposed a mixed-integer programming model for a simplified version of the problem, which only considered the data-take activities of the satellites. Then the author gave two heuristic methods for it and made experimental comparisons based...
Creating an observation schedule is an important part of the earth observing satellites fleet management process. Even for a short term schedule already dozens of earth observing requests requiring several satellites have to be scheduled respecting complex constraints involving multidimensional resource capacities as well as request preferences. This paper first presented the earth observing satellites...
As a new application area of automation, Earth observing satellite imaging provides timely optical/radar information which is used for commercial, environmental and military applications. As the satellite passes over the Earth, onboard camera imaging parameters need to be specified to focus and capture data within request zones. The satellite scheduling problem arises when there are competing client...
