摘要
随着计算机相关技术的发展和GIS产业应用的深入,三维瓦片地图因其视觉效果更加真实而发展前景一片光明,但它也存在如与二维地图之间的联系不是很紧密等诸多不完善之处。针对上述问题,本文利用Auto CAD和3Dmax软件对数据和贴图资料进行三维地形图制作,并通过地图切图得到三维瓦片地图;根据坐标转换算法,将二维数据叠加到三维瓦片地图中,并结合转换后的坐标值偏差现象,修正二三维坐标的转换算法;针对不同角度的三维瓦片地图,实现其多角度之间的相互转换。通过上述操作,提高了三维瓦片地图的精确性和实用性。
With the development of computer- related technology and the further application of GIS industry, 3D simulation map has a bright future because of its more realistic visual effects, but it also has many imperfections ： no closely contact with 2D map, etc. In view of the above question, this paper makes 3D terrain map for data and texture using the AutoCAD and 3DMax softwares and gets 3D tile map by map tiles; according to the coordinate conversion algorithm, converts the 2D data to 3D tile map, and revises the 2D and 3D coordinate conversion algorithm combining with the phenomenon of coordinate deviation after transformation; for 3 D tile map at different angles, achieves its multi -angle mutual conversion. By the above operation, increasing the correctness and practicability of 3D tile map.
