In this study a framework for developing an object-oriented tool –DRONE (areawide Dynamic ROad traffic NoisE simulator) to generate areawide noise contour maps for a road network is demonstrated. This provides faster access to information for abatement of noise policies. The approach for integrating the dynamic output from traffic simulator to noise model, which predicts traffic noise based on ...

In many mapping organizations, existing topographic paper maps comprise the most complete source of elevation. data; the objective of this research is to capture the elevation data (which is in contour form) in a GIS. The topographic relief plate which shows no height information can be scanned into a GIS. The remaining task is then to label these isolines. This paper discusses a methodology fo...

Self-affine maps were successfully used for edge detection, image segmentation, and contour extraction. They belong to the general category of patch-based methods. Particularly, each self-affine map is defined by one pair of patches in the image domain. By minimizing the difference between these patches, the optimal translation vector of the self-affine map is obtained. Almost all image process...
