Abstract

Cultural heritage archiving by collecting and managing archives that include documents, archiving using the Close Range Photogrammetry method by analyzing the density of points and making a 3D model of the Gebouw Van Padangsche Spaarbank building by taking overlapping photo data from different camera angles. The purpose of this study is to analyze the point density and geometry of the 3D mesh to create an archive, improving efficiency in information management. In this study, the results of 3D modeling of the Gebouw Van Padangsche Spaarbank building with a close-range photogrammetry technique were obtained, resulting in 157 photos used to make 3D models. The flying altitude of the drone is not more than 20 m with the height of each line varies, for Line 1 is at the top line at an altitude of 17 m, Line 2 is at an altitude of 10 m, Line 3 is at an altitude of 17 m, height is 7 m and for Line 4 at an altitude of 3 m The results obtained from this analysis are 94,869 tie points from the results of 144,764, thick clouds 15,393,722, and faces 529,237. The results of the comparison of the dimensional accuracy test of the 3D model building to the actual size in the field resulted in an average distance of 0.1408 m.

Abstract

Changes in the earth's surface temperature can have significant impacts on climate, environment, human health, and ecological systems. Global warming becomes increasingly complex when applied to urban contexts, which often experience urban heat island (UHI) effects. This study aims to analyze the relationship between Local Climate Zone (LCZ) and Land Surface Temperature (LST) in Padang City. This study identifies the distribution pattern of LCZ and relates it to surface temperature variability. The data used to map the local climate zone using samples made using WUDADPT and to determine land surface temperature using Landsat 8 OLI/TIRS C1 Level 1 Satellite Imagery. The results of this study are that the Local Climate Zone (LCZ) in Padang City consists of 13 classifications. The type of building that dominates Padang City is Open Low-rise. Meanwhile, Densee Trees dominate the type of natural land cover in Padang City. Land Surface Temperature (LST) in Padang City is dominated by low temperatures covering an area of ​​43,987.94 Ha. The relationship between LCZ and LST in Padang City has a coefficient of determination of 0.608, which means that the level of relationship between LCZ and LST shows a moderate relationship with the greatest influence occurring in the heavy industry classification with a coefficient of determination of 0.904, which means that the influence of heavy industry on temperature is 90.4% or very strong.
