W artykule poddano analizie najważniejsze ogólnoinformacyjne kartograficzne serwisy internetowe o charakterze lokalizacyjnym, prezentujące mapy obejmujące obszar Polski. Po ogólnym scharakteryzowaniu cech dystynktywnych takich serwisów omówiono najważniejsze cechy pięciu kluczowych serwisów tego typu, skupiając się na zakresie treści zawartych w nich map, zastosowanych funkcjach interaktywnych, jak również zwrócono uwagę na najczęściej występujące błędy.

Internet location services constitute a fairly new form of cartographic publications. While there have been several recent papers examining web maps and map-ping, published in Polish cartographic periodicals, so far no comprehensive analysis of cartographic contents of Internet Location Services appeared in print. The purpose of this paper is to offer a survey of five most notable services of this kind in Poland, including both their map contents and interactive functions. According to a recent survey (Geoforum 2009), the most popular websites containing maps of Poland are: Google Maps [S3], Zumi [S5] and Targeo [S4]. Two other important location services, namely DoCelu [S1] and Panorama Firm [S2] have also been included in the analysis. The paper is divided into 5 sections. Section 1 offers a brief introduction into web location services in general with a special emphasis on such services in Poland. The following two sections provide information on general characteristics of such services and the sources of cartographic data. Section 4 reviews the map contents of particular services, addressing separately each of the major thematic layers contained therein, namely: relief, hydrography, settlements, road and railroad networks, boundaries, POI (Points of Interest) and the remaining map elements. Within each thematic sub-section, a con-tent analysis and evaluation of each service have been provided. The following (5) section, offering insight into interactive features, has a similar structure. In an earlier paper (M. Okonek 2000), the author proposed to divide interactive functions of electronic atlases into six distinct categories. In the current one, this classification has been used throughout this section to provide detailed description of interactive functions used in each web map service. The paper ends with a short set of concluding remarks and lines for future development.
Obecnie wiele uwagi poświęca się generacji energii z wykorzystaniem odnawialnych źródeł energii. Czyni się tak, zarówno ze względów technicznych, jak i ekonomicznych. W produkcji energii na poziomie 0,2-1,0 MWel można zastosować technologie oparte na ślimakowym silniku parowym lub organicznym cyklu Rankine’a. Inwestycje te mają duże szanse na uzyskanie wsparcia ze środków z funduszy strukturalnych oraz innych źródeł finansowych UE, wspomagających działania z zakresu poszanowania i efektywnego wykorzystania energii, redukcji emisji CO2 oraz wzrostu bezpieczeństwa dostaw energii.

W artykule dokonano przeglądu interaktywnych funkcji wizualizacji danych geograficznych występujących w atlasach elektronicznych. Po ogólnym scharakteryzowaniu pojęcia atlasu elektronicznego dokonano klasyfikacji funkcji atlasów pozwalających na interakcję z użytkownikiem, opierając się na rozróżnieniu rodzaju informacji uzyskiwanych z ich zastosowaniem.

Electrinoc atlases constitute a fairly new form of cartographic publications. Although the term "Electronic Atlas" appeared in print as early as in 1984 (E. Sielierska), it was not until the early 1990s that first general reference electronic atlases appeared on the market (R.M.Smith 1999). It can be easily noticed that functions included in atlases of this kind require rethinking the concepts of thematic structure, scale and relationships between different elements of the atlas. In an earlier paper (M. Okonek 1997) the concepts of scale and thematic structure of cartographic presentation in electronic atlases were discussed. The intention of this one is to provide a systematic analysis and a classification of interactive features included in such publications. While there have been a few papers devoted to the classification of electronic atlases published to date, most of these seem not to notice the shift in the way that printed and electronic atlases function. Basing on the type of information resulting from the use of the particular interactive features, we propose to discern the following classes of functions: - Navigation. This class of functions enables the atlas unser to move through the maps of an atlas and to customize the atlas content. These functions can be further subdivided into sub-categories. The user can navigate through space (scrolling), time, scale (zooming), map themes (layer selection) or evenforms of cartographic presentation. - Identification. The goal of functions included in this category is to identify names and to provide additional information on objects included in maps. - Orientation. these functions inform the user of this current location on a map and provide directions. These features are most often used in various route planning software packages. - Measurement. Projected to calculate a desired distance/surface on maps. - Analytical Functions. Functions in this class are designed to transform the cartographic representations in electronic atlases into certain derivative products (e.G.a DTM derived from a contour map) - Communication. Function included here are responsible for communicating with the external systems. The examples of such function may include data expost, printing or download.

Autor artykułu, redaktor części kartograficznej elektronicznego 'Atlasu Polski' opublikowanego w 1997 r., po przypomnieniu wydanych dotychczas w Polsce atlasów elektronicznych, prezentuje koncepcję i kolejne etapy opracowania atlasu, jak również zawartość i sposób ujęcia poszczególnych elementów treści.

Atlas Polski, published in 1997 is the second (after Szkolny Atlas Polski) electronic atlas of this country. The cartographic part of this atlas consists of four elements: 1. General-reference map of Poland 2. Thematic maps 3. Thematic city maps 4. Statistical maps. The general-reference map serves as a basic map in this atlas. It consists of 8 thematic layers as well as the map legend. The map contains 5 levels of detail. It is digitized in vector format. The map was prepared using a computer program complied in Borland Delphi 1.0. A set of 27 thematic maps of both physical and socio-economic contents is the second element in this atlas. Each of these maps is available in two levels of detail. Maps are stored in raster format. The diversity of map themes is also reflected by the map design methods. The following methods were applied on these maps: isarythms, graduated symbols, nominal point and areal symbols as well as the dasymetric method. The atlas also contains a set of 7 city structure maps of the Poland's largest cities and metropolitan areas. These maps are also stored in raster format and are available in 2 levels of detail. They major content is composed of the presentation of transportation network and dominant land use forms. The atlas contains a set of 114 statistical maps in 11 thematic categories. Two mapping methods were used in this map group: choropleth and graduated symbol. The basic unit areas are the major administrative units. The electronic atlas elaboration process differs from the elaboration of a printed one. Apart from the strictly cartographic processes, the electronic atlas system also requires design of a map visualization system and a graphical user interface. Also, the very cartographic representations in an electronic atlas posses a number of properties differing from the features of a printed one. ¸
