基于GeoRaster的多源遥感数据存储研究

Storage of multi-source remote sensing data based on GeoRaster

遥感数据源极大丰富,影像文件格式多样,组织方式也较复杂,如何采用统一的接口实现异构多源海量遥感数据的存储是一大难题。本文以多源遥感数据的存储为研究对象,在研究Oracle GeoRaster数据模型的基础上,设计了扩展的基于GeoRaster的多源遥感影像存储模型,利用java JAI与GDAL相结合,实现了多源多格式遥感影像数据的统一存储。

Remote sensing data has the character of abundant sources, multiple type and complex organization. It is a big problem to implement the storage of multi-source massive remote sensing data through a unified interface. This paper takes the storage of multisource remote sensing data as the object to be researched, on the basis of researching oracle GeoRaster data models, an extended storage model based on GeoRaster is designed. By use of the designed storage model, the unified storage of multi-source remote sensing data is implemented with the support of Java advanced imaging API and Geospatial Data Abstraction library.
