Exploring the Utilities of Unmanned Aerial Vehicle (UAV) Imageries for Assessing Planned Housing in a GIS format: A case study of Savar Upazilain Dhaka, Bangladesh

Abstract

People's need for a safe and comfortable place to reside is among the most fundamental. But governments worldwide, notably emerging nations like Bangladesh, are finding it increasingly challenging to build housing to meet their needs in light of their growing populations. Therefore, accurate mapping of the housing project area is required to achieve the goals of having planned housing and a sustainable environment. Using an unmanned aerial vehicle (UAV), the purpose of this investigation is to compile a plot-level GIS database from Mauza at the study site of Arunapalli, Savar upazila of Dhaka district, as well as investigate the advantages and drawbacks of employing UAVs to evaluate housing societies. Orthophoto and DTM were the results of the study. This DTM revealed that the RL of the project area ranged from a minimum of 4.93 meters to a high of 11.85 meters. The majority of the land is taken up by vegetation, around 35.76 percent of the total area. According to the findings of the structural analysis, the research area encompasses a total of 207 different structures. Most of the buildings are homes and other residential land uses.
