Three dimensional (3D) city model is an interesting research topic in the last decade. This is because achieving rapid, automatic and accurate extraction of a realistic model for the large urban area is still a challenge. Consequently, increasing the efficiency of 3D city modeling is required. The objective of this research is to develop a simple a...

One of the most interesting research topics in the last decade is generating 3 Dimensions (3D) city model, nevertheless representing a suitable method to achieve the required rapid, automatic, accurate extraction of realistic model for large urban area used for GIS applications and photogrammetry is still a challenging issue. Consequently, a new te...

In this paper the idea is to combine classifiers with different error types based on Fuzzy Majority Voting (FMV). Four study areas with different sensors and scene characteristics were used to assess the performance of the model. First, the lidar point clouds were filtered to generate a Digital Terrain Model (DTM), and then a Digital Surface Model...

This paper presents work on the development of automatic feature extraction from multispectral aerial images and lidar data based on test data from two different study areas with different characteristics. First, we filtered the lidar point clouds to generate a Digital Terrain Model (DTM) using a novel filtering technique based on a linear first-or...

Coordinate conversion is process of determining and applying the relationship between two sets of coordinates. It answers the following question: “If known the coordinates of a point on one data source, what are the coordinate values for this point on another data source?” The input to the process is coordinates of common points from both coordinat...

Transformation equations from spheroid into Transverse Mercator (TM) projection have been written as expanding shape. This paper describes the preparation of TM formulae in a programmable form, to ease the dealing with it and improve their accuracy, and the effect of computer language on accuracy of TM computation is investigated. However, a two-co...
