Generation and Update of 3D-City Models from Maps and Elevation Data
نویسندگان
چکیده
In this paper we describe a procedure for generating building models from large scale vector maps and laser altimeter data. First the vector map is analyzed. The result is used to mask the elevation data of single buildings and to derive a coarse 3D-description by prismatic models. Afterwards roofs are reconstructed by fitting planar surfaces to obtain a polyhedral model.

Generating 3D city models without elevation data
Elevation datasets (e.g. point clouds) are an essential but often unavailable ingredient for the construction of 3D city models. We investigate in this paper to what extent can 3D city models be generated solely from2Ddatawithout elevationmeasurements. We show that it is possible to predict the height of buildings from 2D data (their footprints and attributes available in volunteered geoinforma...
متن کاملTowards Virtual Maps: On the Production of 3D City Models
In the area of high resolution digital surface model (DSM) generation, great advances have been made by the application of laser scanner systems. These systems have lead to a more economical data capture, but probably more important, to a more faithful reproduction of the object surface. Surface measurement within dense urban areas has become feasible, and even details like chimneys can be obse...
متن کاملEffect of digital elevation model’s resolution in producing flood hazard maps
Flooding is one of the most devastating natural disasters occurring annually in the Philippines. A call for a solution for this malady is very challenging as well as crucial to be addressed. Mapping flood hazard is an effective tool in determining the extent and depth of floods associated with hazard level in specified areas that need to be prioritized during flood occurrences. Precedent to the...

During the past decade, the automatic generation of 3D city models has been a constant topic of research for several universities and cartographic or photogrammetric institutes. These 3D city models have a great potential for many applications, there is a real demand for. The costs of data acquisition are still high. The choice of the input data for a framework is one of the most important key ...
متن کاملGeneration of 3d-city Models and Their Utilisation in Image Sequences
In this paper we describe the construction of a city model and its support for the analysis of image sequences. Our city model consists of building models which were generated from large scale vector maps and laser altimeter data. First the vector map is analysed to group the outlines of buildings and to obtain a hierarchical description of buildings or building complexes. The base area of sing...
