DEM纹理的制作与实现在土地开发整理项目中的应用——以湖南省嘉禾县为例

摘要

Production and realization of DEM texture in land development and consolidation projects is a new trend, the realization of which will provide more information and convenience for the planning and design of the projects. With remote sensing images of the project areas extracted with Google Earth software and the present land use maps as the drawing source,the authors superpose the images and the land use maps and obtain DEM texture, which is used in the land development and consolidation project of Jiahe County. The result shows that it could display more details and more elaborate terrain characteristics after superposing DEM texture.%在土地开发整理项目的规划设计中,利用PhotoShop软件将Google-Earth软件提取的项目区遥感影像图和土地开发整理项目中项目区土地利用现状图进行叠加处理,制作出DEM纹理,并将其应用到湖南省嘉禾县土地开发整理项目(金塘片)中.结果表明叠加DEM纹理后的项目区可显示更多更细的地物特征,使其更为直观.
