## 6 Summary and Conclusions
The terrain development is very accurate, but the very large amount of information to be processed is also time-consuming. Despite the use of better and better algorithms improving the work with the cloud, it is impossible to completely rule out the role of the operator in the project. It is only possible to limit his role. Digital terrain surface models created on the basis of data from aerial laser scanning provide a reliable base of information about the area and areincreasingly used in many areas of life. The latest point cloud computing software is gaining more and more appreciation among users as it enables us to discover new opportunities and save time. After analyzing and comparing different methods of assessing the landscape changes, including the statistical method of WIT, a comprehensive and multidirectional purpose analysis of the use of photogrammetric materials to identify major changes taking place in the foothill landscape was carried out. The presented photogrammetric studies take into account the time vector, giving full quantitative and qualitative characteristics, while the impression and pictorial reception of changes in the landscape are made by visualizing them. The photogrammetric methods can be effectively used for the metric and plastic presentation of the landscape space and also to design changes in the landscape according to our feelings and possibilities of sensual and intellectual perception. One of the important tools used for landscape analysis is DTMs. In the studies, it was used to analyze the variability of the landscape of the submontane area. Analysis using DSMs enables the assessment of the landscape without applying expensive methods related to the development of individual landscape objects in the area. The study is based on the use of aerial photographs and existing, traditional cartographic materials and digital maps. Summarizing the results of the environmental analyses, it should be emphasized that the photogrammetric data can be called full when they are analyzed in conjunction with other information collected in the databases of the spatial information system. Visualization with the use of aerial photographs and aerial scanning enables the identification of objects and the presentation of their spatial arrangement. This is very important due to the complexity of spatial phenomena and their temporal variability. In the image displayed, it is easy to find the sought objects that have changed over time. In the literature related to the study of the natural environment, many methods can be found that assess the landscape. They were created by specialists in various fields and served various purposes. An analysis of the WIT method allows us to conclude that it has features limiting its use in assessing landscape changes (it cannot be used on a macro scale); moreover, it is a labor-intensive method, and it requires cartographic, statistical, and descriptive materials. The proposed new tools allow us to assess landscape changes that are caused by the passage of time and are characterized by high efficiency (a short image processing and analysis time) as well as relatively good results of recognizing changes in buildings, borders, and roads. They were verified on the research object (Kasinka Mala) and compared to the results of the WIT method. The obtained results allowed us to positively assess their suitability for the evaluation of the condition of the landscape at the turn of the analyzed years.
