应用背景15°有限差分偏移建立在波动方程或简化了的波动方程差分基础上的偏移方法。15度偏移差分法实现地震波偏移。反射地震方法是根据在地面上以一定方式进行弹性波激发，并在地面的一定范围（孔径）内记录来自地下弹性分界面的反射波来研究地下地质岩层结构及其物性特征的一种方法。关键技术本代码建立在波动方程或简化了的波动方程差分基础上的偏移方法。常用的有15°差分法和45°...15°时间偏移方程为式中c为波速，τ为以双程时间表示的深度，t，x和P参见“叠前部分偏移”条件。

Navit is a open source (GPL) car navigation system with routing engine. It s modular design is capable of using vector maps of various formats for routing and rendering of the displayed map. It s even possible to use multiple maps at a time. The GTK+ or SDL user interfaces are designed to work well with touch screen displays. Points of Interest of various formats are displayed on the map. The current vehicle position is either read from gpsd or directly from NMEA GPS sensors. The routing engine not only calculates an optimal route to your destination, but also generates directions and even speaks to you.

由灰度矩阵生成栅格格式数据，这是CWzjAoRasterOp类中一个方法，只要有了各个波段的灰度矩阵的值，就可以生成ArcGIS支持的多波段栅格图像，如IMG,GRID,TIFF等。-Matrix generated by the grayscale raster data format, which is a way CWzjAoRasterOp category, as long as the gray band with all the value matrix, we can generate ArcGIS support multi-band raster images, such as IMG, GRID, TIFF, etc..
