Colibri介绍 Colibri是一个基于ENVI/IDL平台实现的一个开源软件包。里边包含了多种多样的算法和程序。 代码是使用不同子文件夹来存储的。每一个文件夹内都含有一些源码文件。在根目录下的Reference Guide.html文件中包含了所有对象及函数的功能介绍、调用方法等,类似于IDL帮助。 Ø Application – General:含有一些通用功能,比如图像分类、创建合成图像、DSM转换为DTM等功能 Ø Application – Toolbox:包含两个GUI应用程序,功能分别为图像分类后处理(可以新增类别、修改类别等)、高光谱数据处理(光谱平滑,可进行批处理)。 Ø Classes:此文件夹包含了一些通用功能代码,主要为自定义类。 Ø Common:此文件夹包含了一些图像处理函数。如图像分类、SVM、RMSE计算等。 Ø Documents:此文件夹包含了一些参考文献和LOGO等文件。 Ø Examples:包含了一些示例代码和示例数据。 (Colibri is a repository for source code developed in ENVI/IDL under the Open Source Initiative. It contains a wide variety of algorithms and applications which are of interest for the remote sensing community. The code is organized in a hierarchical way. At the lowest level, common code performing all kinds of basic functionality is available to the higher levels, i.e. classes and applications. Classes are object based functionalities performing more specific tasks. Both common code and classes are the building blocks for the applications which perform well delineated tasks. All common code, classes and applications are well documented. The complete set of code and documentation are available to the remote sensing community. ENVI/IDL code developers and remote sensing researchers are requested to actively contribute to this ENVI/IDL Code Library in order to obtain a solid reference of user developed applications for the remote sensing community.)
由遥感图像的日数据生成旬数据,一是输出旬数据总和,二是输出旬数据平均值(From the date of remote sensing image data generated late data, the sum of ten days one output data, the second is the average of the output data late)

通过官网下载NOAA卫星的数据,包括AVHRR数据,并对AVHRR数据做了说明(Download AVHRR satellite data through the official website)
前视双基地SAR(Bistatic Forward-looking SAR)(BFSAR)是对双基地工作模式的一种拓展,能对飞行路线正前方区域进行较高分辨率成像,能消除侧视模式中存在的固有成像盲区,是传统侧视模式的重要补充,具有自身不可替代的优越性。因此对于前视双基地SAR的深入研究具有相当的价值。(Forward-looking Bistatic SAR (Bistatic Forward- & SAR) (BFSAR) is a kind of double base work mode of development, can be directly in front of flight path area of high resolution imaging, can eliminate inherent imaging side-looking mode existing in the blind area, is an important supplement of traditional side-looking mode, has its own irreplaceable advantages. So for the front of the further research of bistatic SAR is quite valuable. )
