W publikacji zawarto analizę opracowań kartograficznych, które dostarczają informacji o zmianach zachodzących w krajobrazie. Celem niniejszego artykułu jest analiza opracowań kartograficznych dostarczających informacji o krajobrazie. Na wstępie zilustrowano podział źródeł informacji o krajobrazie, mając na uwadze przedział czasu dla którego źródła te obowiązują. Do analizy wybrano opracowania kartograficzne: ewidencję gruntów i budynków, mapy topograficzne, mapy zasadnicze i ewidencyjne, ortofotomapy, miejscowy plan zagospodarowania przestrzennego oraz studium uwarunkowań i kierunków zagospodarowania przestrzennego. Materiały te rozwijały się stopniowo na przestrzeni dziejów. w artykule skupiono się na ukazaniu rozwoju tych źródeł na ziemiach polskich. Podsumowaniem analizy jest wykres, który przedstawia kartograficzne źródła informacji o krajobrazie występujące na ziemiach polskich na przestrzeni lat. W chwili obecnej wykorzystywane są nowoczesne technologie zakładania, prowadzenia, aktualizacji i udostępniania informacji o terenie w zakresie stanu gruntów. Aby jak najlepiej przedstawić zmiany zachodzące w krajobrazie należy brać pod uwagę zarówno starsze jak i nowe źródła informacji, należy również zwrócić uwagę na stałą aktualizację materiałów.

Cartographic elaboration that provide information about landscape changes are analysed in the article. The purpose of this article is to present the development of cartographic materials that provide information about landscape. At the outset illustrates the distribution of sources information about the landscape whereas the time period for which these resources apply. The following materials were analysed: Polish land register, topographic maps, master map, cadastral map, orthophotomaps, local spatial plan, and study of conditions and directions of spatial development. The article focuses on presenting the development of cartographic sources from Polish territory. The chart made on the basis of analysis shows periods in which each source occurred. Nowadays, modern technologies are used for establishing, maintaining, updating and sharing information on land. In order to properly present landscape changes both the old and new sources of information should be taken into account, also a constant modernization sources should be performed.

The functioning of the forest digital maps and conducting complex silviculture implemented in accordance with the diversified development creates great demand for a quick method of spatial data capture. Currently used data collectors and navigation receivers enable the measurements of the forest, but the results are not reliable taking into account their quality. In this study the evaluation of currently used measuring devices were realized and new, reliable solution that can streamline data capture in the field was proposed. The work was carried out in the Pułtusk Forest District (central Poland). We established five plots in the stand with the alder as a dominant species. 137 reference points were captured using classical surveying methods. We used the following data collectors: Motorola Omnii XT15 and Workabout Pro, Samsung Galaxy Core Plus smartphone and GIS Trimble ProXH navigation receiver. In addition, the unmanned aircraft i.e. popular on the market DJI Phantom 4 was also used. The accuracy was assessed by determining the error of the plot area and the accuracy of control points (MP). It was found that current popular data collectors and smartphones define the plot area with an error of about 3%, the same positioning of the object can be accurate from 2 to 6 meters (tab. 1). The results allow to conclude that the use of smartphones may be important only for draft assessment, and the realization of the measurement using the data collectors should always be preceded by the control measurement on the characteristic points. Significantly better results are obtained by the GIS class receivers (MP less than 2 meters) and using differential correction (MP less than 0.6 meters). However, these devices are used rarely in practice, despite universal access to the network of GNSS reference stations. The use of drone allowed to obtain images for the entire area in 15 minutes. The orthophotomap was automatically made in point−cloud technology. This method gave an error of 1.3% for estimating the plot area and 1.69 meters for the position of control points for objects borders. Given the falling prices of unmanned platforms and low labor intensity of this measurement method, we can assume that it will find widespread use in updating of forest digital maps.

The objective of the undertaken research was to characterize and evaluate the impact of weather and lighting conditions on recording terrain anomalies in the photographs obtained during a UAV photogrammetric flight. The present work describes the use and capabilities of the UAV in the mapping of photo acquisition conditions similar to those performed during inspection flights with the use of a manned helicopter equipped with a hyperspectral camera, in the target range of visible light. The research was conducted in the southern part of Poland (between Gliwice and Katowice), where 7 routes were selected, differing from one another in terms of terrain anomalies (buildings, types of land areas, vehicles, vegetation). In the studies, which involved photogrammetric flights performed using a UAV, different seasons and times of day as well as changes in light intensity were taken into account. The flight specification was based on the main parameters with the following assumptions: taking only perpendicular (nadir) RGB photographs, flight altitude 120 m AGL, strip width 160 m, GSD ≤0.04 m and overlap ≥83%. The analysis of the photographic material obtained made it possible to correct the catalog of anomalies defined previously, since the recognition of some objects is very difficult, being usually below the orthophotomap resolution. When making and evaluating orthophotomaps, problems with mapping the shape of objects near the edges of the frame were found. When a 12 mm lens is used, these distortions are significant. It was decided that for the purpose of generating training data from orthophotomaps, only the fragments containing objects which shape would be mapped in accordance with the real one would be used. Thus, the effective width of orthophotomaps obtained from simulated flights will be approximately 100 m.

The spatial data sets of soil resources are essential for the interpretation of the site-specific ecosystems, not only concerning process investigations, but also for sustainable soil management The objective of the study was to attempt identification of the primary parameters influencing the rational management of soils available without the necessity of carrying out time-consuming and costly field and laboratory research. The research was carried out in the Pawłów commune (north-eastern part of the Świętokrzyskie Voivodeship, Poland). The research included the application of different methods and interpretation of source materials, including (i) digital soil-agricultural map, (ii) annex to the soil-agricultural map at a scale of 1:5000, (iii) soil quality contours, (iv) digital terrain model, and (v) orthophotomaps. Obtaining data concerning soil type and/or agricultural usefulness complexes would require conducting a generalisation process. Publicly available ortophotomaps and cartographic materials in the form of topographic maps and a numerical terrain model were analysed to determine the extent of soils to be protected. The rational management of space and soil resources can be visualised and documented using BIM technology; however, relying on GIS data is not the most straightforward task due to the lack of integration on the BIM-GIS line. This paper presents the current state of the art and attempts to address selected problems in this area.
