lv juan, former deputy director of the remote sensing technology application center of the ministry of water resources and the engineering technology research center for flood control, drought relief and disaster reduction of the ministry of water resources, focused on the application of hydrological models in flood disaster simulation. she said that such models can accurately predict the occurrence and development of flood disasters by simulating physical processes such as water flow movement and rainfall runoff. however, traditional models have certain limitations in computational efficiency and are difficult to meet the needs of rapid forecasting in emergency situations such as sudden rainstorms. the innovative application of core models such as digital twins in flood disaster simulation can allow researchers to use historical flood data to build machine learning models through "flood simulation technology + digital twins" to learn and train the complex relationship between rainfall characteristics and flood processes. in practical applications, you only need to input the current rainfall forecast data to quickly generate simulation forecast results for flood disasters, providing strong support for disaster prevention and mitigation decisions.
spatial information technology can also find application scenarios in the agricultural field. zhao hu, director of the big data development center of the ministry of agriculture and rural affairs, introduced that by developing and utilizing a "one map" of agricultural and rural land across the country and integrating multi-source data, it is possible to achieve full monitoring and precise management of high-standard farmland construction, avoiding duplicate construction and investment. at the same time, combined with all-weather remote sensing monitoring of land use, permanent basic farmland protection and other related work, a three-dimensional supervision system for high-standard farmland construction can be formed to achieve "land management by map".
when talking about using spatiotemporal information technology to promote the construction of a digital china, xu daqi, deputy general manager of china 4d surveying and mapping technology co., ltd., said that it is important for the cloud platform to build a cross-platform capability of productization and service, and achieve ecological interconnection with partners through online services and offline deployment.
