However, the data collected are often challenging to work with, particularly by digitization and visualization. After reviewing these challenges, this article introduces a “semi-structured” approach to sketch map data collection, digitization, and analysis and an open-source software package, “qualmap,” that implements tools for digitizing these data in the programming language R. This approach retains the cartographically accurate base maps used in other sketch map research. However, it superimposes an areal unit of the researchers’ choice to aid in digitization and analysis. The use of a standard areal unit creates additional cartographic and analytic possibilities. The applicability of this approach is illustrated with a sample project that analyzes perceptions of space collected from a convenience sample of college students. The resulting maps’ clustering identifies a “bubble” around their campus that captures much of the travel activity students engage in every week. These data are paired with crime data, which illustrates possible mixed methods extensions of this “semi-structured” approach to sketch mapping.

Evaluating narrative in geoportals for territorial public policies / Luis Manuel Batista in Cartographica, vol 56 n° 4 (Winter 2021)  

Public [article]  inCartographica > vol 56 n° 4 (Winter 2021) . - pp 303 - 319 Titre : Evaluating narrative in geoportals for territorial public policies Type de document : Article/Communication Auteurs : Luis Manuel Batista, Auteur ; Ana Figueiras, Auteur Année de publication : 2021 Article en page(s) : pp 303 - 319 Note générale : bibliographie Langues : Anglais (eng) Descripteur : [Vedettes matières IGN] Géomatique web [Termes IGN] analyse comparative [Termes IGN] carte thématique [Termes IGN] collectivité territoriale [Termes IGN] communication cartographique [Termes IGN] compréhension de l'image [Termes IGN] conception cartographique [Termes IGN] géoportail [Termes IGN] plan local d'urbanisme [Termes IGN] politique territoriale [Termes IGN] Portugal [Termes IGN] web mapping Résumé : (auteur) To do territorial planning, we need several maps referring to different layers of information necessary to represent the territory according to a vast set of variables. At the Portuguese municipal level, the municipal master plan (PDM – plano diretor municipal) is the territorial management tool responsible for long-term territorial planning and ordering. Since the PDM will constrain the citizens’ lives, it should be of easy access and interpretation. However, due to its large amount of information, it is often hard for them to understand what is presented using only static cartographic elements. Comparing 60 Web sites that present geographical information for a wider public, we found that narrative, visual, and interactive elements and data presentation in flexible portions with the necessary information for partitioning, browsing, or querying made the data more engaging. This flexibility is particularly important with large data sets, where decreasing the level of complexity is vital for proper understanding and analysis. We found that geoportals dedicated to territorial public policies lack narrative elements that would improve comprehension. Since it is difficult for the general public to understand the strategy the municipality wants to implement, the desired public participation, although possible, will return poor results.
