Research on Remote Sensing Image Mobile Service Technology for Earthquake Emergency Sites

摘要

After the earthquake, carrying out disaster investigation on earthquake site is one of the primary tasks. Traditional survey methods rely mainly on manual processing, costing a long period of time, which is difficult to meet the post-earthquake emergency response requirements. Using remote sensing image interpretation to obtain disasters information is more efficient, but the accuracy cannot be guaranteed. In response to the problem, this article has realized the full chain technology for providing remote sensing image mobile services for earthquake emergency sites, and built a bridge for information exchange between the earthquake site and the emergency command center. The main issues discussed in this paper include: pre-processing of remote sensing image data into hierarchical slices, which is convenient for packaging and distribution to on-site terminal equipment; constructing a system management platform to facilitate distribution of data to terminal equipment and management of data transmitted back from earthquake sites; developing mobile application for receiving remote sensing image data and reporting on-site survey data. The application of this technology has important practical significance for improving the emergency response capability of earthquakes.
