The Construction and Practice of Big Data Mapping GIS under Low Altitude Remote Sensing

Abstract

This paper introduces the construction and practice of big data mapping geographic information system under low-altitude remote sensing. The combination of low-altitude remote sensing technology, which obtains high-resolution remote sensing data through unmanned aerial vehicles and satellites, and big data technology, which can process and analyze huge geographic information data, provides new ideas and methods for the development of geographic information systems. Starting from an overview of low-altitude remote sensing technology and the advantages of its application, the article discusses the process of building a big data mapping GIS and introduces a practical case based on the system. At the same time, the current challenges and future development trends are also put forward.
