From "civil defense" to "intelligent defense", MapGIS digital base reconstructs coastal disaster prevention ecology
When typhoons carrying heavy rains sweep across the coast of the East China Sea, this beautiful city nestled between mountains and sea always races against an invisible battle. Linhai, this picturesque coastal city, though scenic, frequently faces threats from typhoons and geological disasters. The questions of "when hidden dangers will strike," "how to predict risks," and "how to respond to disasters" remain persistent governance challenges hanging over this coastal city.
Facing numerous pain points in traditional geological disaster prevention methods such as long modeling cycles, low early warning accuracy, and slow emergency mapping, the Linhai Municipal Bureau of Natural Resources and Planning partnered with Zondy Digital to explore a new path. With the MapGIS platform as the core, they integrated cutting-edge technologies including the internet, IoT, artificial intelligence, digital twins, and intelligent algorithms, providing intelligent support for geological disaster monitoring, early warning, and decision-making, and painting a new picture of geological disaster prevention and control.
Intelligent Modeling: From 2D Drawings to 3D "Transparent Crust"
Breaking through the困境 of traditional geological modeling that relies on professional software and complex processes, MapGIS innovatively launched a web-based lightweight modeling tool, achieving a technological breakthrough in geological modeling through B/S architecture, supporting "one-click modeling" in browsers.
Users without professional modeling skills only need to upload standardized Excel borehole data and stratification data according to templates, and can generate geological models online with one click through browsers, significantly lowering the modeling threshold and improving efficiency. Meanwhile, integrating digital twin technology, it incorporates multi-source information such as remote sensing images, borehole data, and BIM models to construct high-precision 3D geological models, achieving integrated visualization and dynamic monitoring of underground geological structures and surface real scenes.
Disaster Early Warning: From Empirical Judgment to Intelligent Prediction
Based on digital twin technology to construct 3D geological space, integrating dynamic monitoring data and geological models to create a comprehensive risk assessment foundation. The established shallow landslide early warning model integrates real-time hydrology, historical disaster data, and geological data, achieving precise early warning for individual hazard points with significantly reduced false and missed alarm rates.
The model dynamically tracks changes in key parameters such as rainfall intensity and groundwater levels, triggering early warning signals in advance and greatly improving response efficiency. Innovatively constructing a "one point, one strategy" early warning mode, it promotes the precise transformation of geological disaster prevention and control from traditional "regional overview" to "point sniping."
Disaster Mapping: From Static Drawings to Dynamic "Risk Maps"
Every second counts in disaster emergency response. MapGIS innovatively developed an adaptive rapid mapping engine, solving the problems of traditional emergency mapping such as "long cycles, rigid styles, and slow updates," and constructed a second-level mapping system covering the entire process of "identification-warning-disposal" for geological disasters, achieving real-time synchronization and updates of emergency plans and on-site situations.
Meanwhile, with built-in knowledge bases of various mapping rules, it can meet the extreme time requirements of "one-click triggering, automatic mapping" for geological disaster prevention and control, and can also flexibly adapt to emergency scenarios in multiple industries and fields, truly transforming professional mapping from "expert skills" into accessible emergency support capabilities.
The "Intelligent Geological Disaster Governance" system based on MapGIS as the technical foundation has achieved visualization, awareness, and control of disaster risks, promoting a leapfrog transformation from "human prevention" to "intelligent prevention" in disaster prevention and mitigation, and helping Linhai City blaze a new path in disaster prevention characterized by "lightweight modeling to reduce costs, precise early warning to improve efficiency, and intelligent mapping to save time." In the future, Zondy Digital will continue to deepen the integrated innovation of GIS with emerging technologies such as digital twins and artificial intelligence, persisting in providing replicable and promotable digital solutions for geological disaster prevention and control, and building a solid security foundation for Beautiful China.
