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.

Abstruct This paper presents the framework for creating of 3D map. The 3D shape and the textures of a building are acquired by analyzing moving picture taken from a running vehicle. However, in the real city environment, it is difficult to obtain 3D data of buildings accurately, because the slight motion of images due to the vehicle motion cannot be removed completely. This paper describes a ap...

The city of Tehran undergoes an increasing growth in population as well as industrial activities, both of which increase the concentration of air pollutants. The current research tries to turn a limited and focused system of air contamination measurement and control to an unlimited and extensive one that examines the concentration of each of the contaminants in any area of Tehran. Accordingly, ...

We implement a solution for the automatic ordering of BAC clones from fingerprint data obtained through full digestion of the clones with four enzymes that leave different 3’ recessed ends and fluorescent labeling. The algorithm is inspired to a previous existing approach for building restriction maps.

Three-dimensional (3D) maps have many potential applications, such as navigation and urban planning. In this article, we present the use of a 3D virtual world platform Meshmoon to create intelligent open data 3D maps. A processing method is developed to enable the generation of 3D virtual environments from the open data of the National Land Survey of Finland. The article combines the elements n...

This paper introduces a new intelligent method to generate vector maps from printed maps to provide a basis for GPS navigation. This new approach has been applied in our GIS-DMG (Digital Map Generation) software, which has four key steps: Map Layers Extraction, Road Network Digitalization, Map Geo-locating and Map Automatic Geo-adjusting, different from typical procedures. These four steps play...
