Sommario/riassunto |

The monograph presents a fully automated procedure for geometric correction of optical satellite images, without any manual intervention during the processing. The resulting orthorectified image is in the national coordinate system and constitutes a suitable source for spatial analyses. In the monograph the original procedure connects several different methods into a single, robust system for automatic generation of orthoimages is documented in detail. The work describes the whole automatic orthorectification process, which comprises four basic modules: a module for extracting and preparing the metadata, a module for automatic extraction of ground control points, a module for calculation of parameters of the geometric model, and a module for orthorectification. The experiments and results with RapidEye and WorldView-2 images are also presented. The experiments evaluate the procedure for automatic extraction of points, the geometric model, the elimination of gross errors, and the positional accuracy of the orthoimages. The analisys of the results indicate that the automated procedure produces orthoimages with a positional accuracy of about two pixels or better, even if several gross errors are present among the automatically extracted ground control points. |
V knjigi je opisan popolnoma samodejen postopek geometričnih popravkov optičnih satelitskih posnetkov, ki deluje brez posredovanja operaterja med obdelavo. Dobljeni ortorektificiran posnetek je v državnem koordinatnem sistemu in predstavlja primerno podlago za |

prostorske analize. V knjigi je detajlno dokumentiran izviren postopek, ki povezuje več različnih metod v enoten in robusten sistem za samodejno izdelavo satelitskega ortofota. Opisan je celoten postopek samodejne ortorektifikacije, ki ga sestavljajo štirje osnovni moduli: modul za branje in pripravo metapodatkov, modul za samodejno določanje oslonilnih točk, modul za izračun parametrov geometričnega modela in modul za izvedbo ortorektifikacije. Poleg modulov so predstavljeni tudi poskusi s posnetki RapidEye in WorldView-2. Opravljeni poskusi so omogočili ovrednotenje delovanja samodejnega postopka določanja točk, geometričnega modela, izločanja grobih napak in oceno položajne točnosti ortoposnetkov. Analiza rezultatov testov kaže, da lahko samodejni postopek izdela ortoposnetke s položajno točnostjo okrog dveh pikslov ali manj, tudi če je med samodejno določenimi oslonilnimi točkami prisotnih več grobih napak. |

Sommario/riassunto |
|
Metropolitan Governance and Spatial Planning explores the relationship between metropolitan decision-making and strategies to co-ordinate spatial policy. This relationship is examined across 20 cities of Europe and the similarities and differences analysed. Cities are having to formulate their urban policies in a very complex and turbulent environment. They are faced with numerous new pressures and problems and these often create contradictory conditions. The book provides a theoretical framework for exploring these issues and links this to a detailed investigation of each city. |
