W artykule przedstawiono przykład zastosowania oprogramowania ArcInfo do redagowania mapy. Przybliżono problematykę wyboru i sposobu wykorzystania danych źródłowych, prezentacji rzeźby terenu w trakcie opracowania średnioskalowej mapy topograficznej przeznaczonej do wydruku.

In 2010 an expedition to the massif of Belukha in the Altai (4506 m a.s.l.) in Kazakhstan was organized. A topographic map in the scale of 1:100,000 had been prepared for the expedition. Ali the editorial works were performed in the environment of GIS ArcInfo package, which had been considered the most advanced in applied cartographic tools. The first version of the map had been verified in Altai and in 2011 a new version was elaborated, which mainly improved relief by addi-tion of rock drawing and modified shading. The map was prepared in 'WGS-84' coordinate system and UTM projection basing on Soviet topographic maps in '1942' coordinate system (downloaded from the Internet) and satellite images from LandsatTM and ETM+. Satellite images were used to update buildings, forests, roads, water-beds and main forms of high-mountain rock relief. ASTER GDEM and SRTM digital terrain models were also used, but their quality was not satisfactory. As a result an original terrain model in 25 m resolution was prepared, basing on vectorized contourlines and other necessary relief elements extracted from topographic maps using ANUDEM algorithm. All the elements of map contents mentioned above were prepared in ArcInfo, with input data not organized into one common database, but rather placed in a layer structure (*lyr files). Rock drawings could not be executed in ArcInfo package (ArcMap module), therefore they were done manually using satellite images. Rock drawings were adjusted to the location of mountain ridges determined basing on topographic maps. The drawing was then scanned, processed graphically in Adobe Photoshop, geo-referred and added to the map. Shading was generated from the original terrain model, detailed to follow the contourlines, modified and retouched in Photoshop, adapting the details to rock drawings and contourlines' location. The presented process of preparation of a middle-scale topographic map shows that the newest version of ArcInfo package (9.3.1) has a lot of potential for map editing, starting from data preparation to the final map. However, for particular features and forms of relief, manual involvement using other vector and raster graphic editors is necessary.

Referat jest próbą prezentacji możliwości analiz na sieci dróg z wykorzystaniem oprogramowania GIS. Tego typu zadania są realizowane za pomocą specjalistycznego oprogramowania do analiz komunikacyjnych. Jednak głównym założeniem autorki było zastosowanie do tego celu oprogramowania alternatywnego, uniwersalnego - jakim jest pakiet Arc/Info firmy ESRI. Baza danych zawierająca sieć ulic miasta Krakowa i okolic wraz z projektowanymi elementami, czyli obwodnicami: wschodnią i północną, posłużyła do analiz ruchu tranzytowego, a także propozycji objazdów, w przypadku wyłączeń pewnych fragmentów sieci. Pozwoliło to na dokonanie oceny wpływu przyszłych inwestycji na poprawę ruchu w mieście oraz zasadności ich lokalizacji.

The paper attempts to present possible uses of GIS software for road network analyses. Tasks of these kinds arc realised with the help of specialist software for transport analyses. However, the main attempt of the author was to use for this purpose an alternative and multipurpose software - the Arc/Info Package by ESRI. Database, containing the street network of the City of Krakow and its adjacent areas including planned elements (the Eastern and Northern ringways) was used to analyze the transit traffic and to propose diversions if some roads are closed. This has allowed to assess the influence of future investments on traffic improvement and to validate their locations.
