北航新地图改版，是GIS的一个作业，对现有地图进行修改！

VC＋MapX实现的鹰眼图与主图联动功能。-VC MapX implementation of the Eagle Eye diagram with the main functional linkage map.

提供了一个GIS二次开发制作专题图的代码，开发语言为C#，需要预先设置engine环境，代码提供了基本的地图制图的功能，包括添加格网，制图输出等一些基本的功能，可以为初学者提供一些很好的建议，具有很高的参考价值。

MAPGIS6.7 软件狗. 使用户不需要狗即可以使用MAPGIS6.7.-MAPGIS6.7 soft dog. It makes users to use mapgis6.7 without hard dog.

实现与MapObject配合的鹰眼图功能，需要有Mapobject控件支持。-MapObject realize with the Eagle Eye diagram with function, the need for support has MapObject controls.

这是我亲自写的一个在GIS地图用的截图的东东，很简单实用，快开帐号吧，天呐。-This is what I personally wrote a GIS map with the Dongdong screenshot, it is simple, practical, quick to open your account, God.

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

Points2Dto3D。将二维点的坐标软换成三维坐标，即增加了高程点Z坐标。-Points2Dto3D. Softly change into the three dimensional coordinates the two-dimensional spot coordinates, namely increased the elevation to select the Z coordinates.
