Within ROUTE4ALL project we created an extended data model of geographical information database suitable for navigation of people with special needs as well as of general population. Moreover, we provide a methodology for its interpretation and a guide for its implementation into navigation devices. The results of the project could be used by navigation device developers for creating a fully-fledged navigation for people with special needs. First, we describe the requirements for the extended data model, which rise from the research we conducted with people with special needs and from the survey of existing solutions. Second, we introduce a catalogue of geographic elements, their attributes and relationships. Finally, we discuss its benefits over the traditional approaches.

W miastach Europy, Azji i Ameryki od wielu lat powstają interesujące kładki dla pieszych, o nietypowym ukształtowaniu. W artykule omówione zostały dwa przykłady takich obiektów, pełniących funkcje „punktu charakterystycznego”.

Jednym z najbardziej rozpoznawalnych symboli miasta jest jego sylweta, widoczna z różnych punktów widokowych w postaci niepowtarzalnej panoramy. Historyczne przeobrażenia krajobrazu miast mogą być gwałtowną metamorfozą, polegającą na dodaniu nowej przeskalowanej dominanty albo na destrukcji istniejącej przestrzeni. Zmiany takie nastąpiły w latach 70-tych ubiegłego wieku w panoramie nowojorskiego Manhattanu, w której pośród imponującej liczby drapaczy chmur pojawiły się dwa nowe wieżowce o niespotykanej dotychczas skali - bliźniacze wieże kompleksu World Trade Center. Tragiczne wydarzenia we wrześniu 2001 roku oraz kontrowersje związane z odbudową „Strefy Zero" uświadomiły wszystkim siłę oddziaływania symboliki prze strzenno-arc hi tektonicznej oraz rozbieżności percepcji krajobrazu współczesnych miast. Dla badaczy i twórców przestrzeni miejskiej stanowi to cenne doświadczenie pozwalające na lepsze zrozumienie procesu przekształcania wizerunku miast w XXI wieku.

The present spatial planning policy of Zielona Góra is an example of the pressure of market economy, in which there is a strong need to obtain new areas for development. In the town there are still, according to assessments, 50 hectares of land without buildings or ready to be developed after buildings which are not used or which are in poor condition have been demolished. However, those are areas which can only be used to intensify town development. They are not large enough and can not be used for objects requiring large areas or for big detached houses built on large plots of land. The sale and development of those areas would not bring noticeable results in a short time. Unfortunately, at the moment, achieving results in distant future is not the goal of the town spatial planning policy. However, it seems that the development of Zielona Góra should be based on completely different assumptions than those on which the present spatial planning policy is based. The town as an urbanized unit should be one with its surroundings as systems which complement one another. The optimisation of the town structure in terms of the tradition of the place and needs of its inhabitants should be a priority. The logic of spatial systems should preserve the connection between the town structure and the landscape architecture. The policy pursued by the town authorities is mainly directed at obtaining budget income and it disturbs the system of spatial planning. This means that institutions which should take care of a balanced development of the administrative commune in all aspects depend mainly on the income to the town budget i.e. the economic factor.

Visual simultaneous localisation and map-building systems which take advantage of some landmarks other than point-wise environment features are not frequently reported. In the following paper the method of using the operational map of robot surrounding, which is complemented with visible structured passive landmarks, is described. These landmarks are used to improve self-localisation accuracy of the robot camera and to reduce the size of the Kalman-filter state-vector with respect to the vector size involving point-wise environment features only. Structured landmarks reduce the drift of the camera pose estimate and improve the reliability of the map which is built on-line. Results of simulation experiments are described, proving advantages of such an approach.
