Urban planning and design strategy based on ArcGIS and application method

GIS is a spatial information system combining geography, cartography, remote sensing and computer science, which is widely used in different fields. As a computer system, GIS can input, store, query, analyze and display geographic data. In the 1980s, GIS gradually began to be applied in the field of urban planning. This kind of digital technology meets people's requirement for regional geographic environment visualization. At the same time, the development of the network has also provided help for the popularization and development of this technology, making the dissemination and sharing of data possible. Nowadays, as an important technology, GIS has been widely used in all fields of urban planning and has gradually become an indispensable part. Arcgis as GIS platform building and applications will be treated as big data analysis and data visualization as an important part of planning, implementation of the software data correlation of traditional urban planning, break traditional design and drawing mode, through the spatial analysis function to generate new information, make decisions and solve problems efficiently, and make a prediction to the development of future city. Through the introduction of Arcgis data organization structure, CAD data loading, mapping and modeling under Arcgis platform and Arcgis spatial analysis function, this paper discusses how to use Arcgis platform to realize the application of urban planning and design.
