Optimization of Urban Disaster Prevention and Mitigation Based on Computer Three-dimensional Mapping

  • Wei Zhu

Abstract

With the continuous acceleration of urban construction, relying on policies such as
"new urbanization", cities have developed greatly, but the supporting infrastructure is
relatively lagging behind. From the perspective of space, this paper changes the
traditional two-dimensional map mode, and builds three-dimensional map based on
SWMM model and geographic information data, so as to realize the three-dimensional
visualization of multi-scale urban disaster prevention data, support the refined
management and governance of the city, and be timely and effective. Disaster
prevention and mitigation are carried out to reduce urban losses.
