Mining activity leads to subsidence troughs and permanent changes in water relations, like the formation of anthropogenic reservoirs. In the Upper Silesian Coal Basin (S Poland), their number is so high that the area is called an anthropogenic lake district. Any form of water retention, in the face of climate change, is valuable. However, the problem is the high variability of these lakes, making it challenging to estimate water resources. An example of this type of anthropogenic lake is the Brandka Pond in Bytom. An original method was proposed, consisting of two stages: reconstruction of the lake bottom relief based on the initial state of the area relief in 1994, i.e. at the beginning of the reservoir formation, and the land subsidence rate calculated for this area. Archival cartographic materials and DEMs from LiDAR data were used and processed in the open-source geoinformation software. Orthophoto maps and satellite scenes were also collected to determine changes in the extent of the pond from 1993 to 2019. Bathymetric data obtained in 2019 during sonar measurements on the reservoir was used to verify the calculations. The pond began to form in the early 1990s, and by 2019, it had reached an area of 178,226 m2, a maximum depth of 5.8 m and a capacity of 421,173 m3. The reconstruction method is accurate and suitable for lakes over 2 m deep, and the calculated capacity differs from the bathymetric data by 0.2%.

“…For this reason, 24 maps on a scale of 1:1,000,000 were created and served as the stimuli to be used when solving different tasks by the users (Figure S1). The thematic content used to prepare the heat maps were wind turbines (point data) from the beginning of the 19th century, derived from the Gaul/Raczyński database [50]. As base maps, 16 Polish districts with their borders slightly changed were chosen.…”

Recently, due to Web 2.0 and neocartography, heat maps have become a popular map type for quick reading. Heat maps are graphical representations of geographic data density in the form of raster maps, elaborated by applying kernel density estimation with a given radius on point- or linear-input data. The aim of this study was to compare the usability of heat maps with different levels of generalization (defined by radii of 10, 20, 30, and 40 pixels) for basic map user tasks. A user study with 412 participants (16–20 years old, high school students) was carried out in order to compare heat maps that showed the same input data. The study was conducted in schools during geography or IT lessons. Objective (the correctness of the answer, response times) and subjective (response time self-assessment, task difficulty, preferences) metrics were measured. The results show that the smaller radius resulted in the higher correctness of the answers. A larger radius did not result in faster response times. The participants perceived the more generalized maps as easier to use, although this result did not match the performance metrics. Overall, we believe that heat maps, in given circumstances and appropriate design settings, can be considered an efficient method for spatial data presentation.

“…The digital editing of cartographic sources is strongly coupled with comparative methods in historical research, in two variations: spatial and chronological. Maps often present the same space at different scales and levels of generalization (Panecki 2020). The content of each map is conditioned by many factors: the purpose of its development, technical capabilities, cartographic knowledge, the conceptualization of space, etc.…”

The aim of the paper is to propose a data model for editing historical records using the example of Karol Perthées’ works from the late 18th century. These consist of cartographic sketches, elaborated on the basis of parochial questionnaires and the maps of palatinates of the Crown, which are at a scale of 1:225,000. The model links the advantages of direct source data representation with scalability and flexibility features, which provide analytical possibilities. The sketches are indexed using the INDXR application and the structure of the model reflects the structure of the source. The maps were analyzed in a GIS environment, but no georeferencing was performed. The data collected separately as symbols and annotations were treated independently and were linked via features. The model is illustrated by a preliminary study of materials covering the area of the Zemborzyce parish near Lublin.
