这是两年前做的东西，刚刚开始学习gis时导师布置的一个作业：莫霍面的一些分析处理！对初学者有用，呵呵～里面有坐标系的关键转换技术，自己建的数学模型自己实现，还有配套的文章发表，呵呵～-That was two years ago so things just started learning gis instructor at the layout of a work : Moho some analysis! Useful for beginners, Ha ha ~ coordinate system with a key switch technology, to build the mathematical model for achieving his, also supporting the article was published, Ha ha ~

本文结合DCT变换的特性，利用分形的Peano一hilbert扫描曲线，对基于DCT变换的图像编码方法进行了研究，并提出了改进方法。主要工作分为两个部分: 一是在分块DCT基础上的改进。对分块后生成的各图像块矩阵，不直接作二维DCT变换，而是先进行扫描，使之重排成一维向量，再进行一维DCT变换，这样可以减少运算量。 其次是对层次余弦变换编码部分的改进。使用层次DCT变换与零树编码相结合的方法，并在扫描编码过程中，按Peano一hilbert扫描顺序进行编码。这样不仅可以减少“块效应”，而且可以加快编码速度。-this paper the characteristics of DCT, using fractal Peano a Hilbert scanning curve, the DCT-based image coding method for the study and improvement of methods. The work is divided into two main parts : First, the DCT block on the basis of improvements. Right after block production of the image block matrix, not for direct two-dimensional DCT, but first scan, so they line up in a heavy-dimensional vector and then a peacekeeping DCT, thus reducing the amount of computation. Secondly, the level of cosine transform coding some of the improvements. The use level of DCT and zero tree coding combination of methods, coding and scanning process, according to a Hilbert Peano code scanning sequence. This will not only reduce the "blocking

sgEarth是一个跨平台的库，可以使用版本号为2.6.2或更新版本的Cmake对其进行编译。有三个方法可以获取osgearth源码：Option1：使用GITosgEarth源码托管于GitHub，所以我们需要一个Git客户端。Windows下推荐TortoiseGit，SVN 小乌龟的Git 版本。评价：该有的功能基本都有了，还是不错的。tarball是linux下最方便的打包工具，是以tar这个指令来打包与压缩的档案。Option3:使用版本控制SVN
