چکیده
This paper discusses the making of three-dimensional geospatial data infrastructure (3D GDI) for Malaysia. The main component of the initiative is 3D city models with CityGML as the standard for data modelling, transfer and exchange. Various aspects of 3D city modelling especially on the construction of the models and texturing of facades via dynamic pulse function are described. The generated models then are utilized in the network. More and more geospatial users deal with three-dimensional (3D) data such as buildings, plants, vegetation, street furniture (including bridges), etc. for various GIS applications within urban environment. One of the applications is 3D modelling for city, i.e. 3D city modelling. The modelling involves various aspects, e.g. texturing, semantic, and spatial database. This paper discusses these three aspects with the introduction of a simple but novel method of texturing of building facades for 3D city models, i.e. synthetic texturing by dynamic pulse function. High quality texturing, semantic modelling for 3D database within CityServer3D environment will form major discussion of this paper. The paper also describes how CityGML can be utilized for semantic modelling of the 3D buildings and also highlights the building blocks of the proposed a “near-future” Malaysian 3D SDI, i.e. 3D city models. It is a “big picture” of the whole idea for the 3D SDI framework for Putrajaya area and eventually for a country-wide area.

Last years witnessed the growth of demand for road monitoring systems based on image or video analysis. These systems usually consist of a survey vehicle equipped with photo and video cameras, laser scanners and other instruments. Sensors mounted on the van collect different types of data while the vehicle goes along the road. Recorded video can be geographically referenced with the help of glo...

A method for the simultaneous co-registration and georeferencing of multiple 3D pointclouds and associated intensity information is proposed. It is a generalization of the 3D surface matching problem. The simultaneous co-registration provides for a strict solution to the problem, as opposed to sequential pairwise registration. The problem is formulated as the Least Squares matching of overlappi...
