Our goal is to respond to the following research questions: (i) which map landmarks are easily remembered? (memorability), (ii) how are task difficulty and recognition performance associated? (task difficulty), and (iii) how do experts and novices differ in terms of recognition performance? (expertise). In this context, we developed an automated area-of-interest (AOI) analysis framework to evaluate participants’ fixation durations, and to assess the influence of linear and polygonal map features on spatial memory. Our results demonstrate task-relevant attention patterns by all participants, and better selective attention allocation by experts. However, overall, we observe that task type and map feature type mattered more than expertise when remembering the map content. Predominantly polygonal map features such as hydrographic areas and road junctions serve as attentive features in terms of map reading and memorability. We make our dataset entitled CartoGAZE publicly available.

Cartographic propaganda in the age of social media: Empirical evidence from Ethiopia / Daniel K. Waktola in Cartographica, Vol 57 n° 4 (December 2022)

Waktola, Auteur Année de publication : 2022 Article en page(s) : pp 281 - 290 Note générale : bibliographie Langues : Anglais (eng) Descripteur : [Vedettes matières IGN] Cartographie [Termes IGN] désinformation [Termes IGN] Ethiopie [Termes IGN] géopolitique [Termes IGN] information cartographique [Termes IGN] propagande [Termes IGN] représentation cartographique [Termes IGN] réseau social Résumé : (auteur) Cartographic propaganda is a conscious manipulation of a map to influence the reader’s belief. Countries often use it to claim disputed territories or project fear over opposing nations or political alliances, but little is known about the manipulations of maps along internal sociolinguistic and political fault lines on social media platforms. The author investigated the nature and intent of propaganda maps in Ethiopia before and after the 2018 government reform based on six purposely sampled maps prominently circulated on social media. While falling short of the acceptable cartographic qualities, the analysis of sample propaganda maps revealed two fundamental characteristics during the pre- and post-government reform. First, their role shifted from a centripetal force in the political coalition to a centrifugal force in the coalition’s disintegration. Second, their mode of dissemination transitioned from cartographic misinformation to disinformation. The findings of this study contribute empirical evidence to the ongoing cartographic information discourse that lags behind the rapidly changing map-making and map-sharing platforms in the age of geospatial and social media revolutions.

A general model for creating robust choropleth maps / Wangshu Mu in Computers, Environment and Urban Systems, vol 96 (September 2022)  

Public [article]  inComputers, Environment and Urban Systems > vol 96 (September 2022) . - n° 101850 Titre : A general model for creating robust choropleth maps Type de document : Article/Communication Auteurs : Wangshu Mu, Auteur ; Daoqin Tong, Auteur Année de publication : 2022 Article en page(s) : n° 101850 Note générale : bibliographie Langues : Anglais (eng) Descripteur : [Vedettes matières IGN] Cartographie [Termes IGN] carte choroplèthe [Termes IGN] incertitude des données [Termes IGN] méthode du maximum de vraisemblance (estimation) [Termes IGN] méthode robuste [Termes IGN] optimisation par essaim de particules [Termes IGN] programmation dynamique Résumé : (auteur) Choropleth maps visualize areal geographical data by grouping data into a few map classes and assigning different colors, shades, or patterns. Recent studies show that data uncertainty, commonly observed in real-life applications, should also be accounted for when determining the best classification scheme. Due to data uncertainty, a few studies note that map units might be placed in a wrong class, and the concept of map robustness has been introduced to minimize such misplacement. Recently, an algorithm has been developed to integrate robustness into the design of the optimal map classification scheme. However, the existing algorithm has two limitations: first, it is only suitable for certain robustness metrics. Second, when identifying the optimal class breaks, the existing algorithm requires predefined candidate class break values, which might lead to sub-optimal solutions. This paper resolves these issues by proposing a new model, namely, the Continuous Robust Map Classification Problem (CRMCP), and the associated solution approach. The CRMCP allows mapmakers to customize robustness metrics according to their data and applications. In addition, a particle swarm optimization algorithm is developed to solve the CRMCP. The model and algorithm are tested using American Community Survey data. Test results suggest that the new approach can find better solutions than the existing algorithm. The study improves the usability of choropleth maps when uncertain geographical attributes are involved and allows spatial analysts and decision-makers to incorporate robustness into the mapmaking process more flexibly.

GANmapper: geographical data translation / Abraham Noah Wu in International journal of geographical information science IJGIS, vol 36 n° 7 (juillet 2022)  

Public [article]  inInternational journal of geographical information science IJGIS > vol 36 n° 7 (juillet 2022) . - pp 1394 - 1422 Titre : GANmapper: geographical data translation Type de document : Article/Communication Auteurs : Abraham Noah Wu, Auteur ; Filip Biljecki, Auteur Année de publication : 2022 Article en page(s) : pp 1394 - 1422 Note générale : bibliographie Langues : Anglais (eng) Descripteur : [Vedettes matières IGN] Cartographie [Termes IGN] apprentissage automatique [Termes IGN] bâtiment [Termes IGN] distance de Fréchet [Termes IGN] empreinte [Termes IGN] morphologie urbaine [Termes IGN] réseau antagoniste génératif [Termes IGN] réseau routier [Termes IGN] système d'information géographique [Termes IGN] texture d'image Résumé : (auteur) We present a new method to create spatial data using a generative adversarial network (GAN). Our contribution uses coarse and widely available geospatial data to create maps of less available features at the finer scale in the built environment, bypassing their traditional acquisition techniques (e.g. satellite imagery or land surveying). In the work, we employ land use data and road networks as input to generate building footprints and conduct experiments in 9 cities around the world. The method, which we implement in a tool we release openly, enables the translation of one geospatial dataset to another with high fidelity and morphological accuracy. It may be especially useful in locations missing detailed and high-resolution data and those that are mapped with uncertain or heterogeneous quality, such as much of OpenStreetMap. The quality of the results is influenced by the urban form and scale. In most cases, the experiments suggest promising performance as the method tends to truthfully indicate the locations, amount, and shape of buildings. The work has the potential to support several applications, such as energy, climate, and urban morphology studies in areas previously lacking required data or inpainting geospatial data in regions with incomplete data.

Mapscapes: Applying anachronic techniques in contemporary maps as a design strategy for new ways of seeing / José Miguel Carvalho Cardoso in Cartographic journal (the), vol 59 n° 2 (May 2022)  

Public [article]  inCartographic journal (the) > vol 59 n° 2 (May 2022) . - pp 120 - 135 Titre : Mapscapes: Applying anachronic techniques in contemporary maps as a design strategy for new ways of seeing Type de document : Article/Communication Auteurs : José Miguel Carvalho Cardoso, Auteur ; Rui Carlos Ferreira Cavadas da Costa, Auteur Année de publication : 2022 Article en page(s) : pp 120 - 135 Note générale : bibliographie Langues : Anglais (eng) Descripteur : [Vedettes matières IGN] Cartographie [Termes IGN] carte ancienne [Termes IGN] carte chorographique [Termes IGN] cartographie historique [Termes IGN] conception cartographique [Termes IGN] dessin cartographique [Termes IGN] paysage [Termes IGN] rédaction cartographique [Termes IGN] représentation cartographique [Termes IGN] seizième siècle Résumé : (auteur) This research upholds the designer's mediatory role in the representation of places and hand drawing as a privileged tool. Given the current technological capacity for an automatic representation of the territory and landscape, one can question if the hand that draws the map is now anachronistic. The hypothesis of hybridism between the landscape observational drawing and the cartographic code is proposed, supported by the historical analysis of maps from the sixteenth century. The resultant anachronistic techniques are systematized as a design strategy, available for use by other authors, elsewhere. The techniques were tested by drawing landscapes and producing maps of places. It is concluded that the transference of anachronistic techniques is relevant in contemporary maps intended for touristic, cultural and commercial contexts, when wayfinding skills are not essential. As an open source, other authors may use the same strategy, applying different anachronistic techniques, based on their own subjectivity.
