“…In the study conducted here, the results for the two experimental groups suggested that the use of the map of choice did not always have a positive effect on performance. In the analysis performed, the preferred map technique was not always more effective than the other two types for completing these tasks, which also occurred for an identical analysis using paper maps (Mendonça and Delazari 2011). Statistical analysis showed no evidence of correlation of subjective preference with the responses in the proposed tasks.…”

“…This is shown by the number of observations and comments on the interface written in the questionnaires. This seems to be a good way of validating the methodology and, consequently, the responses received, although the number of Testing Subjective Preference and Map Use Performance comments was 25% higher in the previous analysis with paper questionnaires (Mendonça and Delazari 2011). Most of the comments were about decisions taken during the reasoning task, usually with explanations, and mostly followed by details and logical flow, even in cases where the answers did not correspond to the ideal responses.…”

“…Each Web page related to one indicator and portrayed the situation in three different years. From results obtained in Mendonça and Delazari (2011), performances were always lower for a reasoning task as the decisions for this task include a detailed analysis of the evolution of the data over time. It was thought that the situation could be improved by using animated maps.…”

“…As explained in Mendonça and Delazari (2011), cartographers were hired to produce maps on which to base this process, using indicators of public health identified by Pastoral as thematic information. The map design took the following factors into consideration: the users were a heterogeneous group of people of different ages, both sexes, and generally without prior knowledge of the analysis of social or economic indicators or professional experience of map use.…”

Maps support many planning activities, from general purpose tasks to in-depth spatial analyses. However, preferences and intuitions, which occur in all human interactions, are often disregarded in use and user research in cartography, and there is evidences that analysis of these factors is desirable. It is commonly believed that there is a positive correlation between subjective preference and objective performance, and there is agreement about the main role of media in map comprehension. To investigate this topic, quantitative experiments were performed, based on a real situation in which students need to make decisions about public health care management in a city. Users were asked about their preferences with respect to map type, and performances in carrying out tasks were measured. The results indicate that for simple visual comparison tasks, the proposed Web map framework was adequate. However, this was not the case for reasoning tasks, where weak performances were registered. Also, user preference among visual variables seemed to be unrelated to better performance, and since performances were poor, the important role played by interface usability and attractiveness in map use is verified. RÉSUMÉLes cartes appuient de nombreuses activités de planification, depuis les tâches générales jusqu'aux analyses spatiales approfondies. Souvent, la recherche sur l'utilisation et les utilisateurs menée en cartographie ne tient toutefois pas compte des préférences et des intuitions qui existent dans tous les échanges humains et des éléments de preuve indiquent qu'il est souhaitable d'analyser ces facteurs. On croit couramment qu'il y a un lien positif entre la préférence subjective et le rendement objectif et l'on s'entend sur le rôle de premier plan que jouent les médias dans la compréhension des cartes. Pour analyser ce sujet, on a procédé à des expériences quantitatives basées sur des situations de la vie réelle au cours desquelles des étudiants doivent prendre des décisions sur la gestion des soins de santé publics dans une ville. On a demandé aux utilisateurs d'indiquer leurs préférences quant au type de carte et l'on a mesuré leur rendement dans l'exécution de tâches. Les résultats indiquent que le cadre cartographique Web proposé suffit pour des comparaisons visuelles simples, mais non pour des tâches de raisonnement à l'égard desquelles les utilisateurs ont produit un rendement médiocre. Il a aussi semblé n'y avoir aucun lien entre la préférence des utilisateurs à l'égard des variables visuelles et un meilleur rendement. Comme le rendement était médiocre, les résultats vérifient le rôle important que joue le caractère utilisable et attrayant de l'interface dans l'utilisation des cartes.

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.

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.
