摘要：随着经济的快速发展，各行各业用图的需求量增大，特别是天地图网站更新及地理国情监测的需要，均要求快速更新地形图及相关产品，但基础比例尺地形图使用传统的航空摄影测量的工作程序更新速度慢，不能为用图者（单位）提供最新的地形图，满足不了工程设计和建设的需求。现在高分辨率遥感影像不仅具备更新速度快，覆盖范围广的特点，同时还具备了强大的几何量测能力，能表现详细的地物地貌，能够满足1：10000地形图地物识别和提取要求。本文就利用高分辨率卫星遥感影像进行1：10000地形图快速更新进行实验，为以后的生产提出合理的建议。

Abstract: The basic scale topographic map can not be updated in time. In particular, to respond to the need of geographic national conditions monitoring and the need of updating the tianditu website, a national geographic information service website, topographies and the related products have to be updated fast. Consequently, it is failing to meet the growing demand of construction and project. The high-resolution remote sensing image has several distinctive features. It is able to cover a large area and provide a detailed picture of landscape. Powerful in geometric measurement, it makes target recognition and extraction possible on a 1:10000 topographic map. In addition, it can be updated fast. This paper reports the experiment that updates the 1:10000 topographic maps with high-resolution satellite remote sensing images. The appropriate suggestions for the application of it are discussed as well.

Key words:high-resolution remote sensing image, topographic map, DLG, DOM, differential rectification, topographic map revision

1概述

过去由于遥感影像几何量测能力的不足,在基础测绘生产中应用范围较小,用于国家基本比例尺地图生产的影像源主要是航空影像，但对于地形制图而言,最重要的是要求影像具有优越的几何量测能力，从而保证在空间定位上的高精度性,在这一点上,过去的中低分辨率遥感影像相比于航空影像就显得大为逊色。当前,高分辨率遥感的兴起, 其不仅具备更新速度快，覆盖范围广的特点，同时还具备了强大的几何量测能力，能表现详细的地物地貌，能够满足1：10000地形图地物识别和提取要求，为测绘生产的数据源选择提供了新的可能。
