基于SPOT5影像的地形图更新研究
Reasearch of updating topographical map based on SPOT5 images
【摘要】 针对1∶50 000地形图现势性差、更新效率低等问题,以SPOT 5全色和多光谱影像作为主要信息源,经过DLG制作和对图像增强、配准、融合、正射纠正等一系列处理后,在ARCGIS基础上,成功完成北京市全市1:50 000地形图的快速更新及其基础地理信息库的建立。
【Abstract】 Aiming at the slow updating speed and low updating efficiency of 1∶50,000 topographical maps,it uses SPOT 5 panchromatic images and SPOT 5 multispectral images as the main spatial information data.After the making of DLG and a series of images processing such as enhancement,registration,merging and orth-correction,it has completed the quick updating of 1:50000 topographic maps and the basic GIS database of Beijing based on ArcGIS successfully.
