研究和总结了基于web service的空间信息集成技术,提出了基于web service的NDVI计算模型服务架构,该方法町以实现空间计算模型的跨平台性和互操作性,大大提高空间计算模型的共享.利用该方法对NDVI进行web service的封装和网络发布,很好地解决了传统植被指数计算模型的共享和互操作问题,也为其他窄间计算模型的web service集成与应用提供了参考.%Through a study and summary of the web services-based integration method of spatial data, the web services-based integration method of spatial computing model was developed. The spatial computing models based on this method can be run on various operating systems and can be used between different software applications. The sharing and interpretability of spatial computing models can be improved based on this technique. This paper took NDVI as an example to introduce the web services-based method and the spatial computing model was encapsulated based on web services, and was then published, so the NDVI model based on web services can be accessed through an internet explorer, that is, NDVI is efficiently and effectively shared based on this method. In this way, other spatial computing models can also be encapsulated with web services. Users who want to use some spatial computing models can search the network for a proper model.
