摘　　要：WebGIS技术的发展,为空间分析功能集成到服务器端提供了良好的基础。目前,地理信息服务器对于发布动态数据的支持性较弱,且常规设计中未包含对动态发布的数据进行自动切片的功能,降低了WebGIS中数据处理的流畅性,影响了使用体验。这里提出一种面向空间分析的开源GeoServer服务自动发布与切片方法,将服务器上空间分析的动态结果自动发布成GIS服务,为加快数据访问速度,进一步将数据进行自动切片。基于该方法设计、开发了高分遥感河流水质动态评价系统,对两期遥感影像进行河流水质对比分析生成差异栅格图像,并将图像结果自动发布、自动切片。结果表明,面向空间分析的开源GeoServer服务自动发布与切片方法,可以动态将空间分析结果发布成GIS服务并自动切片,避免了人工发布的局限性,提升了WebGIS系统的灵活性。The development of WebGIS technology provides a good foundation for integrating spatial analysis into the server.As one of the core functions of geographic information system,spatial analysis is well integrated with WebGIS,and the results of spatial analysis are dynamically generated on the server,which will greatly enhance the flexibility of WebGIS.However,for dynamically generated spatial analysis results,GIS services cannot be released manually,and services need to be automatically released.This paper proposes an open source GeoServer service automatic releasing and slicing method for spatial analysis,which automatically releases the dynamic results of spatial analysis on the server as a GIS service.In order to speed up data access,the data is further automatically sliced.Based on this method,a high-resolution remote sensing river water quality dynamic evaluation system was designed and developed.Two remote sensing images are compared and analyzed for river water quality to generate difference raster images,and the image results are automatically released and sliced.The results show that the proposed new method can dynamically release spatial analysis results into GeoServer and automatically slice them.This method also avoids the limitations of manual releasing GIS services and improves the flexibility of WebGIS systems.
