Study on Management of Large-Scale Urban Demolition Waste Based on GIS

The urbanization process not only promotes the development and transformation of the city, but also produces a large number of demolition waste. However, due to the decentralization of basic data and related technical support, there is currently a lack of large-scale construction waste management methods, which leads to major problems in the management of urban-scale demolition waste. The purpose of this study is to provide decision makers with information management tools for urban scale and project scale. Based on the study of the basic properties, economic benefits and environmental impact analysis of demolition waste, this paper uses the spatial analysis function of Web GIS, and uses JavaScript, HTML, JSP and other development languages. EditPlus text editor is also used as a development tool. At the same time, a lightweight visualization method of massive digital surface model data and urban demolition waste data in the network environment is proposed. Three-dimensional visualization data resources are organized and managed using the three-dimensional data format G1TF. This method can realize information management of demolition waste at city scale, and provide theoretical and practical reference for stakeholders according to economic benefits and environmental impacts.
