基于GIS的小区域气象灾害精细化预警系统

为了提高气象预警信息的准确性、及时性,实现小区域内气象灾害精细化预警,充分发挥预警信息防灾减灾的作用,利用北碚区域内国家级气象站、区域自动站、山洪雨量站、闪电定位系统等探测资料,以.NET、SQLserver、ArcGIS作为开发平台,建立了具有数据质量控制、多重阈值和针对性预警用语的气象灾害精细化预警系统。该系统具有人工预警和自动发送预警的功能。系统的应用,将为广大市民提供更加及时和准确的预警信息,增强预警信息的实用性,有利于信息接受者吸收利用。

A GIS Based Small Regional Refined Meteorological Disaster Warning System

In order to improve the accuracy and timeliness of meteorological early warning information, realize the small-area fine early warning of meteorological disasters, and give full play to the role of early warning information in disaster prevention and mitigation, the data of the national meteorological stations, regional automatic stations, mountain torrent precipitation stations, and lightning location systems in the Beibei area are used to develop the fined meteorological disaster early warning system with data quality control, multi-threshold and targeted warning phraseology, by means of ＂. net＂ SQL server and ArcGIS as the platform. The system has both manual warning and automatic warning functions. Application of the system provides more timely and accurate early warning information to public.
