The use of Building Information Modeling (BIM) for existing buildings based on point clouds is increasing. Standardized geometric quality assessment of the BIMs is needed to make them more reliable an...
Through ASTER, ETM, SPOT5 and IKONOS four kinds of remote-sensing images (a coarse correction) , this paper makes a geometric correction for these four remote sensing images, using the control points ...
In this paper, we propose a recognition technique for geographic features which are represented as closed contours. Our algorithm relies on the planar projective geometry between the contours and expl...
Remotely sensed images are the main source for a variety of mapping and change detection applications. Images from different satellites are employed in several of these applications. However, each typ...
Building reconstruction is one of the most difficult and important 3D modelling problems for urban environment. In this paper, we develop an approach using minimum number of basic geometric elements t...
One of the existence mathematical models is Direct Linear Transformation (DLT). These equations are being regarded because of their simplicity as they are direct. When the height distribution of groun...
Due to more than one hundred of traditional film aerial cameras and too expensive digital ones in China, new type aerial camera with large format becomes the focus of researchers on remote sensing and...
The orthorectification accuracies of Bilsat Multispectral (XS) imagery using a rigorous and eight simple geometric models are presented. Majority of the selected test area was covered by the existin...
Vector data is captured using various methods, e.g. manual digitizing, automatic vectorization etc. Errors or inconsistencies, e.g. self-cutting polygons, identical points etc, can not be avoided, ev...
The successful lunch of IKONOS and QUICKBIRD, and a serious of plans for acquiring the remote sensing images with high resolution let it become possible that the basic spatial information is obtaine...
The Chinese satellites HJ-1 A/B, CBERS-02C and ZY-3 have been recently launched and are considered as the main space platforms on orbit to acquire optical images for monitoring the Earth for various a...
The article presents a conceptual framework for formal geometric reasoning with extended objects in the context of vernacular geography. Vernacular geography is concerned with place names and their re...
In order to generate complex virtual cities, models of buildings have to be defined in advance. A common approach describes individual components of these buildings, which are in turn restricted by ge...

Nowadays Geographic Information Systems (GIS) tend to represent and analyse in three dimensions. It requires new analytical threedimensional objects in GIS and have been initiated by the indu...
