摘要
地理信息系统中许多数据都用栅格格式来表示。随着计算机技术、卫星、传感器等科技快速发展,栅格数据的生产能力大幅度提高,大量应用于各行各业。主要研究对栅格数据信息的进一步挖掘应用,从系统原理、系统组成、应用分析三方面,介绍了一种连续型栅格数据预测系统。通过该系统的方法,可以得到未来时间点的预测栅格数据,观察到栅格数据发展演变的趋势,从而给相应决策提供科学依据。
Many data in geographic information system(GIS)are represented in the raster format.With the rapid develop?ment of computer technology,satellite,sensors and other technologies,the production capacity of raster data is greatly im?proved,and raster data is widely applied to all walks of life.In this paper,further mining and application of raster data is main?ly studied.A continuous raster data prediction system is introduced in the three aspects of system principle,system compositionand application analysis.With this system,the predicated raster data in the future time point can be obtained,and the trend ofraster data development and evolution can be observed,so as to provide scientific basis for relevant decisions.
