Conventional methods used are based o n either "raster-vector conversion" o r " l i n e following" and require a lot o f manual input and computing time. The system developed here is based on automated recognition of color contour lines from a rasterized topographic map and automated tracing of the sectional heights o f the recognized lines.

3d Modelling of Topographic Objects by Fusing 2d Maps and Lidar Data
In the past few years the number of applications that use 3D information of topographical objects increased rapidly. With the growing demand for 3D topographic data the need for automated 3D data acquisition also grows. Height information can be extracted from airborne or terrestrial acquisition methods, but can also be modelled as implicit semantic information. Adding height information to exi...
متن کاملContour Lines Recognition from Raster Topographic Maps
Map digitization is still an ongoing research in development of GIS, photogrammetry, remote sensing, military, urban planning and etc. Majority of recent approach, either associates with human interaction or semi-automated process are insufficient in various aspects. There are usually time-consuming, inefficient, and shown inaccuracies in digitized data. This research is intended to develop an ...
متن کاملFloating Model for Building Reconstruction from Topographic Maps and Lidar Data
A novel approach of Model-based Building Reconstruction (MBBR) from topographic maps and LiDAR data called Floating Models is proposed in this paper. Floating models are a series of pre-defined primitive models which are floating in the space. Its size is adjustable by shape parameters, while its location and rotation is controlled by pose parameters. A building is reconstructed by adjusting th...
متن کاملExperiences with Multiresolution and Multifrequency InSAR Height Model Generation
Interferometric synthetic aperture radar (InSAR) has become a broad field encompassing the use of both airborne and spaceborne sensors operating at a range of wavelengths and resolutions. This paper derives general conclusions from experiences at the Remote Sensing Laboratories of the University of Zürich with a variety of airborne and spaceborne InSAR sensors. Results from multiple systems ope...
متن کاملAutomatic Contour Labeling for Scanned Topographic Maps
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...
