交叉定点查找程序在tlecrosspoint目录下，使用Ground Track Generator源码计算轨道坐标，GDAL读取陆表掩膜，NOAA代码计算太阳角度，TLE历史数据从https://celestrak.org/申请。

# Ground Track Generator

A utility to write satellite ground tracks as GIS-compatible [shapefiles](https://en.wikipedia.org/wiki/Shapefile). Orbits are modelled with Dan Warner's [C++ SGP4 library](http://www.danrw.com/sgp4-satellite.php), based on ["Revisiting Spacetrack Report #3"](http://www.celestrak.com/publications/AIAA/2006-6753/), by David Vallado, Paul Crawford, Richard Hujsak, and T.S. Kelso. [Two-line element](http://celestrak.com/NORAD/elements/) (TLE) sets of orbit parameters are read as input. [Shapelib 1.3.0b3](http://shapelib.maptools.org/) is used to generate the shapefiles.
