Urban Digital Map Updating From Satellite High Resolution Images Using GIS Data
نویسندگان
چکیده
In this paper, we propose two methods aiming at updating Geographic Information System (GIS) urban maps using satellite high-resolution remote sensed images. Both methods are based on the input of a priori knowledge provided by GIS data, and a Digital Surface Model (DSM). This article introduces theoretical aspects of our methods; implementation is currently ongoing.

Object-based updating of land-use maps of urban areas using satellite remote sensing
Geographical information in the form of maps is continuously subjected to change, especially in urban areas. Therefore maps have to be updated, which can be done using satellite remote sensing techniques since many satellites are in orbit today. In this paper several object-based classification and change detection techniques are investigated. An important aspect in map-updating is the translat...
متن کاملIdentification of Urban Characteristic Using Ikonos High Resolution Satellite Image
Land use patterns are fragile and sophisticated in Taiwan. In order to rapidly derive detail information of land use/land cover, it is necessary to employ remote sensing techniques because of its broad area coverage and fast data acquirement. The purposes of this research are to use high-resolution satellite images, such as IKONOS, to obtain urban land use information, and to apply fuzzy algori...
متن کاملGeneration of Coarse 3d Models of Urban Areas from High Resolution Stereo Satellite Images
With the emergence of more and more satellites delivering very high resolution (VHR) imagery with ground sampling distances in the range of one meter or below the generation of three dimensional urban models directly from space may become possible. Such models are required for many applications in areas where no up-to-date detailed urban mapping exists like in developing countries. Besides the ...
