05. A case study on the construction of 3D Geospatial information for the urban trees

Abstract

Urban areas are characterized by dense population density and the air is severely polluted due to daily receiving countless amounts of harmful emissions from factories, vehicles and products of chemical origin. Therefore, trees help filter out dirt, and at the same time emit a lot of oxygen, trees act as the lungs of the city. Due to, building 3D Geospatial data to manage and monitor trees in tallying and preventing acts of encroachment on trees as well as inspection is urgent. The objective of this paper is to build a 3D geospatial dataset for the urban tree system for Ha Long city based on modern geospatial technologies. The 3D geospatial dataset of the urban greenery system was established based on the combination of low-cost drone technology with popular software such as Excel, ArcMap, Sketchup, FME. It helped create a complete product to serve the needs of the current urban green tree management in our country.
