摘　　要：HDF4文件常用于中分辨率成像光谱仪(MODIS)产品数据的存储,可存储多种类型的数据,但是文件数据结构复杂。目前,HDF GROUP开发的操作HDF4文件的函数库只可用于Fortran语言和C语言,其他编程语言缺少比较系统读写HDF4文件的方法。Arc GIS虽支持大部分栅格数据格式,但不支持多数据集层次式存储的HDF数据格式。为此,设计基于C#语言操作的HDF4文件中间件,解决Arc GIS无法创建多数据集HDF4文件等问题,并给出中间件的核心思想和具体应用实例。将该中间件应用于环保部生态环境遥感产品生产分系统项目中,结果表明,在处理MODIS产品数据时,解决了C#语言无法创建多数据集HDF4文件等问题,验证了该中间件的实用性。HDF4files are used to store the data of Moderate-resolution Imaging Spectroradiometer（MODIS）products,and it can store various types of data,but its data structure is complex. At present,the function libraries of HDF4 file which are developed by HDF GROUP can only be used in Fortran and C language,other programming languages lack the method of reading and writing HDF4 file systematically. Although Arc GIS supports most of the raster data,it does not support multiple data sets hierarchical storage of HDF data format. This thesis designs a middleware based on C#language of operating HDF4 file,and it solves some problems such as Arc GIS unable to create multiple datasets HDF4 file,and it introduces the core idea and the concrete application of the middleware instances. This middleware is applied in environmental protection of the ecological environment of remote sensing products production system project,and it solves some problems such as C#language unable to create multiple datasets HDF4 file when handing MODIS product data,and it verifies the practicality.
