In this paper, a series of lunar map projection formulas are deduced including azimuthal projections, cylindrical projections and conical projections. The lunar map projections software is compiled. By caculating lunar map projection distortions, their projection distortion rules are found. Base on the lunar exploration mission, the lunar map projection scheme is given in this paper. The azimuthal conformal projection or the circumcenter perspective azimuthal projection is usually used in small areas, especially in two poles. When the whole map of the moon is needed, the azimuthal conformal projection or the circumcenter perspective azimuthal projection is used within 10° in the poles, and the traverse tangent cylindrical conformal projection or the normal secant conical conformal projection can be used in else areas, furthermore, band-division is necessary to reduce the projection distortion.

The tactile directional map is similar to regular directional maps in function. Yet, due to the fact that it requires specified Braille explanation and larger tactile elements, the information density on the tactile directional map is relatively lower. Consequently, a tactile directional map is normally not as delicate and not as comprehensive as a regular directional map. The purpose of this study is to examine the appropriate size of various elements on the tactile directional map and to develop a set of design principles in order to create one that better meets the need. It first explores the way the visually impaired use the tactile directional map and inquires about their views and suggestions.

一般导引地图上有指示性图示，超越文字的藩篱，能让大多数人能理解，且可简化版面的设计；然而触觉地图虽与一般地图相类似，但增加了点字说明和一些触觉元素，可是却鲜少有图像，这是由於点字和一些触觉元素的特性使然，因而使得触觉导引地图上的资讯密度相对较低，造成触觉导引地图缺乏像明眼人导引地图一样地设计完善，也没解释这麽清楚、更缺少图像化的设计，若是维持和一般导引地图相同的资讯密度，则触摸导引地图的面积会过大，超出了一般人手部可触及的范围，造成了视障者触读的不便，这都会使得资讯残缺及迷失，甚而产生一些不可知的危险状况。

ABSTRACT: The UAV navigation system's performance is improved through embedding the geography information model that can process the vector map data in the system by using MapX, In this paper, how to navigate and plan the UAV flight course in the vector map is investigated. The basic control and operation for vector map in the geography information system is introduced, and the flight course is designed and modified in the map. In addition, 2D vector map can't orient UAV in 3D space, so the altitude model is added in the UAV navigation system to realize 3D orientation by integrating 2D vector map with altitude plot. The simulation results in the UAV simulation system indicate that the navigation system can monitor and control UAV efficiently and intuitionally.

没有办法，自己试着换了个地图生成工具，谁知道换了没过一天内容页权重全降了，好多连载影片快照都变成了N天前的，地图那一样显示待定，不过地图里的内容不一样，以前生成的地图只有时间和地址，没有更新频率和优先级，后面用的在线生成工具有优先级和更新频率，不知道是不是因为后面的地图有优先级把内页默认的优先级别降低导致的降权还是什么其他原因，这里是站长们高手云集的地方，见多识广，我的地图现在一直都是显示待定状态，站是http：//www.dy3166.cn，首页权重没有变，就是内页权重没有了，希望高手们帮忙找下原因，申明，本人在此发帖绝非炒作，是确确实实碰到了这个棘手的问题，希望高手们能够帮忙解答下，谢谢了。

To increase the security of the watermark, a new binary image encryption algorithm based on TD-ERCS map is presented. The watermark is encrypted by a chaos sequence generated by TD-ERCS map; A novel color image watermarking algorithm is proposed based on discrete chaotic map and 2-dimensions discrete wavelet transform. The watermark is encrypted by the new binary image encryption algorithm, and the encrypted watermark is embed into four sub-bands of the most deep level of blue branch of host image by three-level wavelet transform, and the embedded positions are determined by general cat cha otic map; A novel color-image blind detection watermarking algorithm is proposed based on integer wavelet transform and subsampling. The scrambled watermark is encrypted and embed into the low sub-bands after four sub-images of the Y branch of host image is transformed by two-level wavelet transform, and the embedded positions are determined by Logistic chaotic map, this watermarking scheme can realize blind extraction.
