However, enclaves and exclaves have not been defined with sufficient formality for automatic identification yet. To identify enclaves and exclaves more generally by computational means than current definitions existing in the literature, this article proposes expressive and generalized mathematical definitions of enclaves and exclaves based on point-set topology. A novel Boundary Extended 16-Intersection Model is developed in this article to identify enclaves, and 74 possible spatial configurations of enclaves are distinguished according to conditions of intersections for polygons in partitions and enclaves. The classic Dimensionally Extended 9-Intersection Model is employed to identify exclaves, and two possible spatial configurations of exclaves are distinguished according to conditions of intersections for polygons in partitions and exclaves. Applications of the proposed definitions are exemplified by the identification of enclaves and exclaves in prototypes and in the real world.

Lines of power: The eighteenth-century struggle over the Norwegian–Swedish border in Central Scandinavia / Anne Christine Lien in Cartographic journal (the), vol 59 n° 2 (May 2022)  

Public [article]  inCartographic journal (the) > vol 59 n° 2 (May 2022) . - pp 102 - 119 Titre : Lines of power: The eighteenth-century struggle over the Norwegian–Swedish border in Central Scandinavia Type de document : Article/Communication Auteurs : Anne Christine Lien, Auteur ; Anders Lundberg, Auteur Année de publication : 2022 Article en page(s) : pp 102 - 119 Note générale : bibliographie Langues : Anglais (eng) Descripteur : [Vedettes matières IGN] Cartographie ancienne [Termes IGN] carte transfrontalière [Termes IGN] délimitation de frontière [Termes IGN] dix-huitième siècle [Termes IGN] géographie historique [Termes IGN] géographie politique [Termes IGN] géopolitique [Termes IGN] Norvège [Termes IGN] Suède Résumé : (auteur) The final position of the Norwegian–Swedish border was determined in 1751, after challenging negotiations. This paper focuses on central parts of Scandinavia and investigates the role of cartography in the border positioning process. The examination of a wide variety of historical maps before and after the border treaty provides insight into the differing opinions on the border region's shifting affiliation. Other factors that helped to shape the borderline were a turbulent political situation with shifting sovereignty over the area in question, as well as conflicts over valuable resources. The findings indicate that cartographic evidence had an important role in the position of the Norwegian–Swedish border in central Scandinavia. The paper adds to our understanding of maps as a political tool as well as of the role of resources in border processes, and provides new knowledge on how cartography influenced a national border between two countries fighting for land, resources and hegemony.

A constraint-based approach for identifying the urban–rural fringe of polycentric cities using multi-sourced data / Jing Yang in International journal of geographical information science IJGIS, vol 36 n° 1 (January 2022)  

Public [article]  inInternational journal of geographical information science IJGIS > vol 36 n° 1 (January 2022) . - pp 114 - 136 Titre : A constraint-based approach for identifying the urban–rural fringe of polycentric cities using multi-sourced data Type de document : Article/Communication Auteurs : Jing Yang, Auteur ; Jingwen Dong, Auteur ; Yizhong Sun, Auteur ; et al., Auteur Année de publication : 2022 Article en page(s) : pp 114 - 136 Note générale : bibliographie Langues : Anglais (eng) Descripteur : [Vedettes matières IGN] Analyse spatiale [Termes IGN] délimitation de frontière [Termes IGN] données multisources [Termes IGN] entropie de Shannon [Termes IGN] espace rural [Termes IGN] estimation par noyau [Termes IGN] Kiangsou (Chine) [Termes IGN] programmation par contraintes [Termes IGN] transformation en ondelettes [Termes IGN] urbanisation [Termes IGN] zonage (urbanisme) [Termes IGN] zone rurale [Termes IGN] zone urbaine Résumé : (auteur) Studies on urban–rural fringes, which represent regions facing various urbanization problems caused by rapid expansion, have steadily increased in recent years. However, problems persist in the quantitative delimitation of such regions. Based on the characteristics of abrupt urbanization-level changes in urban–rural fringe areas, we propose a constraint-based method in this study to detect the urban–rural fringes of cities with a spatial polycentric structure of ‘Main center–Subcenter’ based on data from multiple sources. We used the proposed approach to delimitate the fringe areas of Jiangyin and Zhangjiagang and identify their urban main center and subcenter pre-defined by their city master plans, towns, and rural hinterlands. Comparison of the identified results of different single urbanization indices, a single detection center, kernel density estimation, and a single constraint revealed that the patch density and Shannon’s diversity index of the proposed method were higher in urban–rural fringes and smaller in city centers and rural hinterlands. This suggests that the landscape of urban–rural fringes delimitated by the proposed method is more fragmented, diverse, and complicated, thereby performing better. This study is significant for future urban spatial analysis, planning, and management.

Mapping power / Ben Ori Gitai (2022)  

Public Titre : Mapping power : Landscape transformation in the Jordan Valley Type de document : Thèse/HDR Auteurs : Ben Ori Gitai, Auteur Editeur : Zurich : Eidgenossische Technische Hochschule ETH - Ecole Polytechnique Fédérale de Zurich EPFZ Année de publication : 2022 Importance : 348 p. Format : 21 x 30 cm Note générale : Bibliographie A thesis submitted to attain the degree of Doctor of Sciences of ETH Zurich Langues : Français (fre) Descripteur : [Vedettes matières IGN] Cartographie thématique [Termes IGN] analyse diachronique [Termes IGN] bornage [Termes IGN] carte hydrographique [Termes IGN] cartographie ancienne [Termes IGN] document cartographique [Termes IGN] frontière [Termes IGN] géopolitique [Termes IGN] histoire [Termes IGN] irrigation [Termes IGN] Israël [Termes IGN] Jordanie [Termes IGN] lever topographique [Termes IGN] paysage [Termes IGN] territoire [Termes IGN] transformation Résumé : (auteur) The interaction of three variables—territory, cartography, and terrain—can account for landscape transformation processes at Naharayim/el Baqura, in the Jordan Valley, over the last century and a half. This interface is examined across three historical periods marking the passage from nomadism to sedentism: The Ottoman Period (1858–1917), the British Mandate (1918–1948), and the statehood period (1948–1994). Adopting a hybridized and interdisciplinary approach at the juncture of history, landscape architecture, and geopolitics, this work performs an in-depth analysis of the three variables in each period and examines their relationship to power. The analysis emphasizes territorial concepts and border-making, mapping practices, land survey techniques, infrastructure, agricultural development, and water regimes. It will be shown that mapping has been a medium of politics, with landscapes often being subjugated to political or territorial ambitions. Data is gathered from primary sources, including some previously unknown from the periods in question, fieldwork, interviews, a point cloud data set from both banks of the Jordan River, as well as contemporary social scientific scholarship. It is argued that landscape is neither a natural feature nor a man-made system of engineered spaces, but rather the outcome of a dynamic interaction between natural landscape, human imagination, and various iterations of power, be they natural, theological, technological, political, or military. It is this dynamic interaction across space and time that this work attempts to map. Note de contenu : 1. Domesticated Landscape: Ottoman Imperial Period (1858–1917) 2.
