Abstract: Meteorological disasters affect the growth of crops and cause serious losses to agricultural production. In order to avoid the negative impact of meteorological disasters on agricultural production to the greatest extent, an agrometeorological disaster monitoring and early warning platform should be established as soon as possible. GIS technology is the latest technology based on geospatial and using geographic model analysis method to obtain a variety of spatial dynamic geographic information. It has a large number of applications in the field of agrometeorological disasters. This paper discusses the agrometeorological disaster monitoring and early warning system platform built by GIS technology.
