百度地图嵌入的经典例子，适合学习地图嵌入的同学使用。(Baidu map embedded in a classic example, is suitable for the students to use embedded learning map.)

说明：  本程序可读取国家标准地球空间数据交换格式CNSDTF DEM数据,这种格式与美国USGS DEM数据格式相比较,有些简单,不包含椭球体,投影方式等元数据,实际上就是投影后的平面格网数据. (Read CNSDTF-DEM)

System Defining the state diagram, how to make a state diagram and where the system will stand if it is in one state.

图像A中0表示水体，1表示植被，2表示裸地；B中4表示水体，2表示植被，1表示l裸地。 本程序将B的分类编码改成和A一致；以A为参考图像生成参考矩阵；计算总体精度和kappa系数。(Image A shows water body in 0, vegetation in 1, bare land in 2, water body in 4, vegetation in 2 and bare land in 1. In this program, the classification coding of B is changed to the same as that of A, the reference matrix is generated with A as the reference image, and the overall accuracy and kappa coefficient are calculated.)

Compared to the development of computers, or the Internet, or even cars, the evolution of aviation equipment appears to be very unhurried. Several factors contribute to this very gradual pace, but one of the most important is the extreme care with which any innovation affecting safety has to be examined, evaluated, analyzed, and tested. Satellite navigation equipment for aircraft is not an exception, so predicting its future for the next20 years is relatively easy compared to predictions for other fields. In this paper first of all we will describe briefly the challenges that satellite navigation must solve to be available solution for aviation. Then, we will describe the systems that have been developed to overcome these challenges and the performance they offer today, or will offer very soon. There is currently an explosion in satellite Navigation: before the end of this decade there will be over three times more satellites, offering civil signals in two distinct frequencies (as opposed to one today).
