结合DEM数据对SAR影像数据（ENVISAT影像）进行几何校正，最终结果表现为将SAR影像校正到地理坐标上，并进行了灰度重采样(The geometric correction of SAR image data (ENVISAT image) is carried out with DEM data. The final result is that the SAR image is corrected to the geographic coordinates, and the grayscale resampling is carried out.)

说明：  Unet实现语义分割，对于初学在帮助很大(Unet realizes semantic segmentation, which is very helpful for beginners)

相当经典的信息论导论和编码的课件哦~~ 2009年9月18号更新的，我们上学期刚刚用过的~~ 网上估计是没有的哦-Quite a classic introduction to information theory and coding courseware oh ~ ~ September 18, 2009 update, we have just spent last semester ~ ~ Online estimates are not, oh ~ ~

说明：  maTLAB肌电信号处理程序，包括滤波和整流(matlab EMG processing programme)

说明：  使用matlab实现三维点云建模源码，快速方便。可运行。(Matlab is used to realize the source code of 3D point cloud modeling, which is fast and convenient. Operational.)

电机温升测试系统,适用于工作频率为50/60Hz的单/三相小功率异步电机（≤5KW）、串级电机、电动工具的绕组温升测量。适用于工作频率为50/60Hz的电源变压器、充电器、电感镇流器的绕组温升测量。带电原理：在带电工作情况下测量绕组的直流电阻，并用公式折算成温升。专为电动工具定子，转子温升测量而开发，其中定子采用带电法，转子采用断电法-motor temperature test system is applicable to the frequency of 50/60Hz single/three-phase asynchronous motors power the small ( 5KW), Cascade motor, electric tools winding temperature measurement. Applicable to the frequency of 50/60 Hz power transformers, chargers, the inductance ballasts winding temperature measurement. Charged Principle : Live in work measurement of the winding resistance DC, and the formulas used converted into temperature. Electric tools for the stator and rotor temperature measurement and development, which use charged stator, rotor features a power law

北大青鸟的java学习文档，一共有4份，这是第一份，希望对大家有帮助。-Beida Jade Bird to learn the java files, a total of 4 copies, this is the first, in the hope that everyone has to help.

Python参考手册 是扫描版本的，原先网上下载的是没有目录的，我自己做了目录方便查询(Python Reference Manual is a scanned version of the original download is no directory, I made a convenient directory inquiries)

说明：  pdf关键字坐标获取,itext 插件使用可以根据返回的坐标数据做一写加工处理(pdf keyword get and highline)

实现用gdal读取高程tif，修改tif(The realization of using GDAL to read the elevation TIF and modify the TIF)
