Then this thesis presents another SLAM algorithm-the Relative Map Filter, The RMF is however disadvantaged by the inability to guarantee consistency of the estimated relative map. The following sections introduce a new navigation filter - the Geometric Projection Filter or GPF. The consistency of the estimated relative map is enforced by the application of the constrained estimator to an inconsistent relative map produced by a standard RMF.

然后介紹了SLAM問題的結(jié)構(gòu)99在线精品，分析了絕對地圖濾波器的性質(zhì)黄色a片视频网导航，介紹另一種解決方法—相對地圖濾波器，但是相對地圖濾波器產(chǎn)生不一致的相對地圖一区高清精品视频在线观看，因此在相對地圖濾波器的基礎(chǔ)上應(yīng)用約束估計(jì)產(chǎn)生一致的相對地圖影音先锋视频资源，這就是幾何投影濾波器，從而有效的解決了SLAM問題男人和女人做视频毛片。

In this paper, the theories of lunar control network foundation and lunar map projection are studied. Three foundation methods of lunar control network and the progress in American lunar control network are summarized and analyzed.

The type of map projection has diverse.

地圖投影類類長樣。

The selection of map projection is very important for the production of maps. Its primary task is to decide the mapping equations for the coordinate conversion from the sphere to the plane.

制作地圖過程中人人干全免费黄色视频，選擇投影是一個(gè)重要的程序色色色丝袜，它主要任務(wù)系決定制圖區(qū)從球面轉(zhuǎn)換至平面的制圖方程式。

It's obviously that it's not practical if you use such broken and wrinkled plane mapping. So we must adopt special methods to spread the curved surface, which is called map projection theory.

若用這種具有破裂或褶皺的平面繪制地圖狼色精品中文字幕在线视频，顯然是不實(shí)用的日韩午夜精品福利久久，所以必須采用特殊的方法將曲面展開，使其成為沒有破裂或褶皺的平面欧美精品一区二区福利视频一区，于是就出現(xiàn)了地圖投影理論a片乱伦网站。

Mapping hemispheres and other major land areas usually entails selection of the map projection that most closely suits the data presented. In some cases , this can mean that entire sets of data must be transformed.

In this paper, the author introduces component and OpenGIS including the specification of Spatial Reference System Components —Interfaces and Classes. After analyzing and comparing several methods of map projection transformation, the author chooses the inverse transformation method as the main one.

The sixth part: Studies on the dynamic changes of soil retention function value of ecosystem in YUYANG District. Utilized ERDAS8. 5 to interpret the remote sensing image and get LUCC data and vegetation information of YUYANG District. Utilized R2V5. 5 to digitize administrative map, topographic map, vegetation picture, soil distribution map and meteorological website map. Utilized ARCINFOR8. 3 to change every digitization layer to the same projection, to generate Tyson polygon, to structure DEM and do vector polygon overlay. Utilized ARC VIE W3. 3 to obtain the grid data topographic slope and slope length from DEM data of YUYANG District, and then, turned every coverage layer into grid layer and do grid polygon overlay to gain data about dynamic changes of value of soil retention of ecosystem in YUYANG District, at last, the author analyzed the features of the spatial-temporal changes and its reason.The seventh part: Studies on the dynamic changes of fixing drifting sand against wind function value of ecosystem in YUYANG District.
