“…Surveying methods in cartography are studied through: directly supervised surveys, tasks performed in the field by means of mobile devices, direct observation of the user, observation with remote saving of the user's movement and eye-tracking observation (Cybulski 2021;Horbiński et al 2021;Medyńska-Gulij et al 2020;Cybulski 2020). Collecting data by means of online survey constitutes one of the best methods of obtaining subjective information about users' opinions (Horbiński et al 2020).…”

“…Homogenous groups of respondents with the suitable number of users are usually invited to participate in surveys (Wielebski and Medyńska-Gulij 2019). In studies devoted to multimedia cartography the number of respondents oscillates between 20 and 100 for surveys on the evaluation of a single map version (Medyńska-Gulij et al 2020), which increases to the significantly higher number for several map versions (Cybulski and Horbiński 2020;Cybulski 2020).…”

The main focus of this article is to examine the interpretation of twelve cartographic symbols on the map in Valheim. The authors set the research goal: to investigate how players and non-players interpret the symbols. The Valheim video game, which was released in 2021, is a survival game set in an open world. The authors noticed that game developers did not provide a direct explanation of the map symbols used, which could result in a different interpretation and experience of the game. The authors adopted a survey on the LimeSurvey platform as research methodology. This survey tool was used to gather information on experiences and interpretations of map symbols among a diverse group of respondents. Using online forums allowed one to disseminate the survey to a large audience of players from all over the world. Then, using the categorisation method for individual questions, a large database of respondents’ answers was created. Through the analysis, the authors checked the interpretation of symbols and presented the results in the form of graphs. Then, using statistical tests, they analysed the relationship between individual symbols. The study reveals that there are intergroup differences in responses to symbols directly related to the game. With more complicated symbols that did not emphasise an unambiguous answer, both groups of respondents had a problem with indicating the meaning of the symbol. For future research, it is worth continuing research on the interpretation of various map symbols not only in games, but also in all cartographic products.

“…The results showed that improving visual hierarchy affected viewing behavior and response time. Studies of similar design were conducted with other types of materials, for example 2D and 3D pie charts [12], cartograms [13], maps of spatial accessibility [14], graduated symbols in relation to spatial distance between them [15] or flow maps [16]. All of these provided empirical evidence valuable for formulating the optimal solution for a particular map type, and guidance on how to refine a selected map type.…”

It is acknowledged that various types of thematic maps emphasize different aspects of mapped phenomena and thus support different map users’ tasks. To provide empirical evidence, a user study with 366 participants was carried out comparing three map types showing the same input data. The aim of the study is to compare the effect of using choropleth, graduated symbols, and isoline maps to solve basic map user tasks. Three metrics were examined: two performance metrics (answer accuracy and time) and one subjective metric (difficulty). The results showed that the performance metrics differed between the analyzed map types, and better performances were recorded using the choropleth map. It was also proven that map users find the most commonly applied type of the map, choropleth map, as the easiest. In addition, the subjective metric matched the performance metrics. We conclude with the statement that the choropleth map can be a sufficient solution for solving various tasks. However, it should be remembered that making this type of map correctly may seem easy, but it is not. Moreover, we believe that the richness of thematic cartography should not be abandoned, and work should not be limited to one favorable map type only.

“…These techniques are currently lacking and this has prevented a detailed documentation of all visual distance parameters of the study. For instance, there is some evidence in the literature that the spatial distance between symbols impacts the performance of map reading tasks on graduated symbol maps (Cybulski, 2020), and of colour discrimination tasks on choropleth maps (Brychtová and C ¸öltekin, 2017). Measuring spatial distance between symbols on an interactive mobile map is a challenge in its own right and was thus not tackled during this work.…”

Choropleth maps and graduated symbol maps are often used to visualize quantitative geographic data. However, as the number of classes grows, distinguishing between adjacent classes increasingly becomes challenging. To mitigate this issue, this work introduces two new visualization types: choriented maps (maps that use colour and orientation as variables to encode geographic information) and choriented mobile (an optimization of choriented maps for mobile devices). The maps were evaluated in a graphical perception study featuring the comparison of SDG (Sustainable Development Goal) data for several European countries. Choriented maps and choriented mobile visualizations resulted in comparable, sometimes better effectiveness and confidence scores than choropleth and graduated symbol maps. Choriented maps and choriented mobile visualizations also performed well regarding efficiency overall and performed worse only than graduated symbol maps. These results suggest that the use of colour and orientation as visual variables in combination can improve the selectivity of map symbols and user performance during the exploration of geographic data in some scenarios.
