    NAMO Géoweb

    Une plateforme pour valoriser la narration et la modélisation de l’espace géographique et des territoires

    Jean-Pierre Chery1, Marie Gradeler1, Vincent Bonnal2,3,4

    Revue Internationale de Géomatique, Vol.31, No.2, pp. 355-376, 2022, DOI:10.3166/RIG.31.355-376© 2022

    Abstract The need to enhance and share generic and original information from different research projects, led to the design of a dedicated geoweb, called NAMO. Its design uses open and free functionalities that demonstrate their flexibility in an agile and iterative approach. It is in particular the development of two dimensions of valorization and positioning in geoweb 2.0 that is highlighted: narrative mapping and systemic modeling. The use of geographic information, in particular in co-construction and open science approaches, can thus be better equipped.

    Classification and clustering of buildings for understanding urban dynamics

    A framework for processing spatiotemporal data

    Perez Joan1, Fusco Giovanni1, Sadahiro Yukio2

    Revue Internationale de Géomatique, Vol.31, No.2, pp. 303-327, 2022, DOI:10.3166/RIG.31.303-327© 2022

    Abstract This paper presents different methods implemented with the aim of studying urban dynamics at the building level. Building types are identified within a comprehensive vector-based building inventory, spanning over at least two time points. First, basic morphometric indicators are computed for each building: area, floor-area, number of neighbors, elongation, and convexity. Based on the availability of expert knowledge, different types of classification and clustering are performed: supervised tree-like classificatory model, expert-constrained k-means and combined SOM-HCA. A grid is superimposed on the test region of Osaka (Japan) and the number of building types per cell and for each period is computed,… More >

    Implementation of a solar model and shadow plotting in the context of a 2D GIS

    A validation based on radiometric measurements

    Thomas Leduc, Xenia Stavropulos-Laffaille, Ignacio Requena-Ruiz

    Revue Internationale de Géomatique, Vol.31, No.2, pp. 241-263, 2022, DOI:10.3166/RIG.31.241-263©2022

    Abstract The adaptation of public spaces to episodes of intense heat is now a major challenge for cities. With this in mind, this article presents a contribution aimed at delineating and handling the shadows on the ground or in a horizontal plane at a given height, whether it comes from buildings, street furniture or the tree cover. After a comparison with shadows obtained via two reference tools, we present two urban sites that mix shadows of different origins and, in addition, different indicators. The results of the simulations are compared with pyranometric surveys carried out on site. The aim of these… More >

    Geometric Morphometrics Applied to Cartography

    Frédéric Roulier*

    Revue Internationale de Géomatique, Vol.32, pp. 17-37, 2023, DOI:10.32604/RIG.2023.045458

    Abstract The morphological differences between two geographical maps can be highlighted by a polycentric distance cartogram resulting from a bidimensional regression. Beyond the communicational interest of the transformations thus produced, the method makes it possible to reveal the differences in structure and therefore constitutes a real research tool. However, bidimensional regression can only compare the shape of two maps. Since the 1990s, geometric morphometrics has revolutionized the morphological analysis of natural structures (and others). It has since been applied in many fields of research but not in cartography. This article describes the theoretical and methodological bases of a method combining bidimensional… More > Graphic Abstract

    An Overview of Modern Cartographic Trends Aligned with the ICA’s Perspective

    Maan Habib1,*, Maan Okayli2

    Revue Internationale de Géomatique, Vol.32, pp. 1-16, 2023, DOI:10.32604/rig.2023.043399

    Abstract This study provides a comprehensive overview of modern cartography innovations and emerging trends, highlighting the importance of geospatial representation in various fields. It discusses recent advancements in geospatial data collection techniques, including satellite and aerial imagery, Light Detection and Ranging (LiDAR) technology, and crowdsourcing. The research also investigates the integration of big data, machine learning, and real-time processing in Geographic Information Systems (GIS), as well as advances in geospatial visualization. In addition, it examines the role of cartography in addressing global challenges such as climate change, disaster management, and urban planning in line with the International Cartographic Association’s (ICA) perspectives.… More >

    ECGAN: Translate Real World to Cartoon Style Using Enhanced Cartoon Generative Adversarial Network

    Yixin Tang*

    CMC-Computers, Materials & Continua, Vol.76, No.1, pp. 1195-1212, 2023, DOI:10.32604/cmc.2023.039182

    Abstract Visual illustration transformation from real-world to cartoon images is one of the famous and challenging tasks in computer vision. Image-to-image translation from real-world to cartoon domains poses issues such as a lack of paired training samples, lack of good image translation, low feature extraction from the previous domain images, and lack of high-quality image translation from the traditional generator algorithms. To solve the above-mentioned issues, paired independent model, high-quality dataset, Bayesian-based feature extractor, and an improved generator must be proposed. In this study, we propose a high-quality dataset to reduce the effect of paired training samples on the model’s performance.… More >

    Champs et objets pour mieux représenter les phénomènes dans leur contexte géographique

    Anne Ruas, Ha Pham, Laura Pinson

    Revue Internationale de Géomatique, Vol.29, No.2, pp. 185-205, 2019, DOI:10.3166/rig.2019.00081

    Abstract Many studies and research aim at better knowing phenomena such as pollution or climate. The fields of value representing these phenomena can be visualized on scientific visualization tools which do not have the richness of symbolization specific to the GIS, in particular for the georeferencing and for the representation of the vector objects describing the geographical context. The representation in raster on GIS is possible but limited. However, at the scientific level, it is important to be able to co-visualize the fields describing phenomena in their geographical context to better analyze them and make assumptions about the interactions between a… More >

    Cartographie de l’aléa érosif dans le bassin sud du Litani-Liban

    Hussein El Hage Hassan1 , Ghaleb Faour2, Laurence Charbel3, Laurent Touchart4

    Revue Internationale de Géomatique, Vol.29, No.2, pp. 159-184, 2019, DOI:10.3166/rig.2019.00072

    Abstract Water erosion is a degradation form that results in the stripping of mineral and organic elements from the soil. Due to the impact of meteoric factors (rain, wind) this global phenomenon, soil erosion, affects the productivity of agricultural land. Water erosion is a global phenomenon that affects the productivity of agricultural land. The absence of a protective cover and intense precipitation made the Litani River Basin a vulnerable region to water erosion. Besides, the absence of climate data has brought about erosion hazard mapping using a qualitative method which combines factors such as tillage erosion, infiltration into the rocks, land… More >

    Utilisation du modèle PAP/CAR et du SIG pour un zonage du risque d’érosion hydrique

    Exemple du bassin versant de Tessa (Tunisie)

    Nassira Zouaoui, Radhia Mansour, Abdessalem El Ghali

    Revue Internationale de Géomatique, Vol.29, No.3, pp. 361-380, 2019, DOI:10.3166/rig.2020.00096

    Abstract In the humid Mediterranean regions, particularly the NW of Tunisia, the Tessa catchment area is characterized by torrential and irregular rains, combined with significant deforestation, which causes severe erosion that carries away and redistributes the soil. The process of water erosion is very frequent and changes its dynamic aspect according to the evolution and spatial variation of the lithological nature of rocks, the geomorphology of landscapes, the geometry of watersheds and their bioclimatic situation. In this study, an appropriate methodological flowchart was followed by applying the PAP/RAC erosion mapping method, which is based on the principle of weighting the main… More >
