We discuss general frameworks in which models of spatial movement may be developed. In particular, the article considers the object–field and Lagrangian–Eulerian dichotomies, and the SNAP/SPAN ontologies of the dynamic world, and classifies the variety of informatic structures according to these frameworks. A major challenge is transitioning between paradigms. Usually data is captured with respect to one paradigm but can usefully be represented in another. We discuss this process in formal terms and then describe experiments that we performed to show feasibility. It emerges that observational granularity plays a crucial role in these transitions.

Invariant spatial information in sketch maps — a study of survey sketch maps of urban areas / Jia Wang in Journal of Spatial Information Science, JoSIS, n° 11 (September 2015)  

Public [article]  inJournal of Spatial Information Science, JoSIS > n° 11 (September 2015) Titre : Invariant spatial information in sketch maps — a study of survey sketch maps of urban areas Type de document : Article/Communication Auteurs : Jia Wang, Auteur ; Angela Schwering, Auteur Année de publication : 2015 Note générale : bibliographie Langues : Anglais (eng) Descripteur : [Termes IGN] cognition [Termes IGN] croquis topographique [Termes IGN] invariant [Termes IGN] objet géographique [Termes IGN] zone urbaine [Vedettes matières IGN] Géovisualisation Résumé : (auteur) It is commonly recognized that free-hand sketch maps are influenced by cognitive impacts and therefore sketch maps are in complete, distorted, and schematized. This makes it difficult to achieve a one-to-one alignment between a sketch map and its corresponding geo-referenced metric map. Nevertheless, sketch maps are still useful to communicate spatial knowledge, indicating that sketch maps contain certain spatial information that is robust to cognitive impacts. In existing studies, sketch maps are used frequently to measure cognitive maps. However, little work has been done on invariant spatial information in sketch maps, which is the information of spatial configurations representing correctly the real world. We aim to study such information from a cognitive perspective. This paper first presents basic spatial objects identified in sketch maps and then introduces sketch aspects that capture invariant spatial information. The accuracy and reliability of these aspects were evaluated by a human study. We collected sketch maps from participants, extracted and measured spatial relations of identified spatial objects, and in the end analyzed the accuracy and statistical significance of these relations. Based on the statistical survey, we propose in this paper a set of seven sketch aspects that constitute invariant spatial information, along with a spatial analysis method to measure them. The findings of these aspects help to understand which spatial information is preserved under the transformation from the physical world to human sketch maps.
