چکیده
At present orthophotographs are essential sources of information in all areas. The generation of these products in urban areas can be difficult and specific rectification methods are neededin order to obtain advanced orthoimages that usually have been denominated as true orthophoto. In this paper, the principal results of a research project (DATOS –Development of an Advanced True Orthoimage System for urban information source, sponsored by PROFIT Program from the Spanish Ministry of Industry, Tourism and Comerce) are presented. This system is developed thanks to the collaboration of a private company Altais S.L. and the University of Jaén, using data from the company HIFSA for the different phases of the work. In this contribution, the different phases for the development of the system and the obtained basic results are presented.

Geometrical Building Modeling and Its Application to the Ortho-Rectification for Aerial Images
Due to the huge demand and the importance of 3-D city models, an effective solution for geometrical building modeling is indispensable. From the application point of view, an interactive system for geometrical building modeling based on a semi-automatic approach is presented. A true-orthophoto rectification scheme based on the generated building models is also proposed. The data used in the pro...
متن کاملTrue Ortho-photo Generation from High Resolution Satellite Imagery
Ortho-photos provide valuable spatial and spectral information for various GIS and mapping applications. The absence of relief displacement and the uniform scale in ortho-photos enable interested users to measure distances, compute areas, derive geographic locations, and quantify changes. Differential rectification has traditionally been used for ortho-photo generation. However, differential re...
متن کاملDesign of the Reactor, Selection of Catalyst for Ortho to Para Hydrogen Conversion and Preliminary Design of Cryogenic System for its Liquefaction
Hydrogen is an unusual substance in that its molecule exists in two forms, known as ortho and para, with markedly different properties. Energy level of the ortho molecule is higher than para, therefore, the latter is employed for industrial purposes. Consequently, for a high conversion of ortho to para hydrogen a catalyst reactor must be employed. Therefore, one of the main obj...

This paper presents a new bridge management system (J-BMS). It is integrated with a concrete bridge rating expert system that can be used to evaluate the serviceability of existing concrete bridges. The proposed J-BMS not only evaluates the performance of bridges, but also offers a rehabilitation strategy based on a combination of maintenance cost minimization and quality maximization. In this ...
متن کاملStrategic planning of urban transportation system based on sustainable development dimensions using an integrated SWOT and fuzzy COPRAS approach
Today, urban transportation has attracted urban planners’ and researchers' attention because of air and noise pollution problems associated with it. In Shahrkord city in Iran, no plans have been made for sustainable transportation, and the available poor transportation infrastructure is not responsive to the growing population of the city. This issue has inflicted the city with serious problems...
