“…However, it would be desirable in the future to check the convergence of the drawn route in real time. In addition to the complexity of tasks (based on the number of turns), measures such as average darkness, image compression, or edge detection determine the map complexity [74]. Therefore, differences in the graphic load of road maps with the satellite and vector background may affect the results.…”

There is no consensus on the importance of satellite images in the process of memorizing a route from a map image, especially if the route is displayed on the Internet using dynamic (animated) cartographic visualization. In modern dynamic maps built with JavaScript APIs, background layers can be easily altered by map users. The animation attracts people’s attention better than static images, but it causes some perceptual problems. This study examined the influence of the number of turns on the effectiveness (correctness) and efficiency of memorizing the animated route on different cartographic backgrounds. The routes of three difficulty levels, based on satellite and road background, were compared. The results show that the satellite background was not a significant factor influencing the efficiency and effectiveness of route memorizing. Recordings of the eye movement confirmed this. The study reveals that there were intergroup differences in participants' visual behavior. Participants who described their spatial abilities as “very good” performed better (in terms of effectiveness and efficiency) in route memorizing tasks. For future research, there is a need to study route variability and its impact on participants’ performance. Moreover, future studies should involve differences in route visualization (e.g., without and with ephemeral or permanent trail).

“…While older-generation interactive maps [4,37] required costs reaching €350-400 (about €150-200 for the map and €200 for the electronics), one TouchIt3D map can be printed for €15; adding in a tablet costing €120 does not reach even half of this sum. Moreover, when using one tablet for ten tactile maps, the average price per map falls under €30.…”

“…First, these maps need to be greatly simplified so that the map complexity is at a low level and map symbols are easily interpretable by touch [3]. This requires a high level of generalization applied to source data to avoid a complexity present in many current maps [4]. Furthermore, tactile maps intended for independent movement are usually of a large scale.…”

Despite the growing efficiency of the map-design process in general, tactile mapping has remained peripheral to mainstream cartography. For a specific group of people with visual impairment, however, tactile maps are the only effective way to obtain a complex idea about the geospatial distribution of the surrounding world. As there are numerous specifics in creating these 3D maps and only a limited group of users, tactile products have usually been either very simple creations or, on the other hand, difficult and expensive to produce. Modern trends and progress in the availability of new technologies (e.g., 3D printing) bring new possibilities for keeping tactile map production both effective and up to date. Therefore, this paper aims to present a methodology to apply the TouchIt3D technology to link 3D-printed multi-material tactile maps with a mobile device. Utilizing this solution resulted in a set of interactive tactile maps following current trends of inclusive education. Using OpenStreetMap data together with a semi-automated workflow significantly lowered expenses compared to antecedent maps with similar functionality. A semi-automated workflow was designed, focusing on three use cases of independent movement: walking, using public transport, and tourism.

“…The graphical load of this atlas is the lowest. A metric for measuring the graphic map load was introduced by Barvir and Vozenilek [21]. The last atlas from SHOCart lies somewhere between these two.…”

Over 600 geography teachers answered an online survey containing 30 questions about school world atlases, an integral part of geography education. The study measured the importance and frequency of use of atlases, identified the most frequently used school atlases, and determined the type of tasks solved with atlases and the supplementary teaching aids used. The authors analysed the individual responses of teachers and investigated the relationships between the various responses. To maximise the survey’s information value, many of the questions were open-ended, and teachers responded in the form of plain text. To extract information from these answers, linguistics methods were used. Teachers assessed the importance of atlases as essential. Over 90% of them used atlases in either every lesson or every second lesson. The most important factor in the use of atlases was the experience of the teachers. Those with longer praxis used atlases more often than less experienced teachers. Teachers considered thematic maps as the most problematic part of the atlases. The most frequently solved tasks were the simplest, such as identifying objects on a map. The findings of the survey quantified the importance of atlases in geography education and can assist geography teachers, atlas publishers, and cartographers in general.
