However, UHI studies on cities in mountain regions are still lacking. This study aims to contribute to this endeavor by monitoring and examining the formation of surface UHI (SUHI) in a tropical mountain city of Southeast Asia –Baguio City, the summer capital of the Philippines– using Landsat data (1987–2015). Based on mean surface temperature difference between impervious surface (IS) and green space (GS1), SUHI intensity (SUHII) in the study area increased from 2.7 °C in 1987 to 3.4 °C in 2015. Between an urban zone (>86% impervious) and a rural zone ( Numéro de notice : A2017-720 Affiliation des auteurs : non IGN Thématique : IMAGERIE Nature : Article nature-HAL : ArtAvecCL-RevueIntern DOI : 10.1016/j.isprsjprs.2017.09.008 En ligne : https://doi.org/10.1016/j.isprsjprs.2017.09.008 Format de la ressource électronique : URL article Permalink : https://documentation.ensg.eu/index.php?lvl=notice_display&id=88405 [article]

Measuring urban volume: geospatial technique and application / Ronald C. Estoque in Tsukuba geoenvironmental sciences, vol 11 ([01/12/2015])

Public [article]  inTsukuba geoenvironmental sciences > vol 11 [01/12/2015] . - pp 13 - 20 Titre : Measuring urban volume: geospatial technique and application Type de document : Article/Communication Auteurs : Ronald C. Estoque, Auteur ; Yuji Murayama, Auteur ; Takeo Tadono, Auteur ; Rajesh B. Thapa, Auteur Année de publication : 2015 Article en page(s) : pp 13 - 20 Note générale : bibliographie Langues : Anglais (eng) Descripteur : [Vedettes matières IGN] Applications photogrammétriques [Termes IGN] analyse spatiale [Termes IGN] hauteur du bâti [Termes IGN] image ALOS-PRISM [Termes IGN] modèle numérique de surface [Termes IGN] modèle numérique du bâti [Termes IGN] volume (grandeur) [Termes IGN] zone urbaine Résumé : (auteur) Geospatial techniques based on remote sensing and geographic information system (GIS) are important in urban studies. However, based on traditional techniques, the analysis of the intensity ans spatial pattern of urban land use is, in most cases, based only on the lateral extent of built-up lands (two-dimensional). The increasing availability of geospatial data, such remote sensing satellite imageries and digital surfaces models, provides an opportunity for the integration of the third dimension in urban analysis, i.e. height of urban features such as high-rise buildings, into urban studies, and thus enables the estimation of the so-called urban volume. This study introduces a geospatial technique for estimating urban volume, focusing on the use of a digital surface model (DSM) derived from Alos PRISM data. It also presents a method for deriving a digital terrain model (DTM) from a DSM. The proposed technique was tested in Makati City, Metro Manila, Philippines. Overall, the results show that the proposed technique is capable of taking into consideration the height dimension in urban analysis. The proposed two-step grid-based method for deriving a DTM from DSM is also implementable and promising. In this method, there is a need to calibrate the size of the mesh for identifying the pixels or points to be used in DTM interpolation. This is because different mesh size can produce subtantially different DTMs, suface feature height values and urban volumes estimates.

Geospatial analysis of urban landscape patterns in three major cities of Southeast Asia / Ronald C. Estoque in Tsukuba geoenvironmental sciences, vol 10 (december 2014)

Landsat-8 imageries for 2013 and 2014 were used to classify the urban land-use/cover of the three cities. Furthermore, various class-level landscape metrics were computed to facilitate spatial analysis. The results reveal that the proportional extent or density and physical connectedness of built-up lands in the three cities are inversely related to the gradient of the distance from the city center. In contrast, the fragmentation of built-up lands is directly related to the gradient of the distance from the city center. In the comparison of the three cities, the density of the urban development of Manila is relatively higher than that of Bangkok, but more especially that of Jakarta. The urban landscape of Jakarta is relatively more fragmented or dispersed than that of Bangkok, but more especially that of Manila. In terms of physical connectedness, Manila’s urban landscape is relatively more aggregated than that of Bangkok, but more especially that of Jakarta. The study results show that the gradient analysis and landscape metrics integrated approach can be used to examine and compare the spatial patterns of various complex urban landscapes.
