Study on Forest Fire Spread Model Based on MODIS Image

Abstract

In order to improve the study on the happen and spread of forest fires, people established forest fire spread and forecasting model through the data which came from experiments and observations. Base on MODIS data, this study used data technology of remote sensing image to enhance image, then got data sequence for the models from the fusion image and established the spread and predicted model of forest fires through the integration of Gray. The process of the modeling is simple, Data is easy to get, and the model has the strong generality, so the relative error of half of predicted data based on the gray models was less than 1%, 25% less than 5%,and 25% between 5% and 10%.
