3D geomorphological photointerpretation at a scale of 1:5000 as an input for the territorial development of the city of Duran

Abstract

This study contemplates the geomorphological photointerpretation as an input for the planning and territorial development of the city of Durán. The study area includes the urban expansion zone of the city, which will be photo-interpreted in order to provide inputs for decision-making regarding the order and use of the territory. For the analysis of the shape of the relief, photogrammetric blocks have been photointerpreted in 3 dimensions, the Reception Capacity of the Territory and the Constructive Physical Aptitude were also determined, which have the objective of zoning places of constructive compatibility and incompatibility, these objectives were achieved through the modeling of multipurpose geospatial information at a detail scale (1: 5,000) and the survey of soil information. The results indicate that Durán is located within two morpho-pedal landscapes: 1) on ancient volcanic rocks: basic lavas, tuffs, breccias; and, 2) the low flood plain. In conclusion, the application of 3D geomorphological photointerpretation at a scale of 1: 5,000 allowed zoning the city depending on its capacity to host construction activities, which is an important input for territorial development and decision-making with respect to it.
