Semitransparent construction technology for geospatial information service chain

This paper discusses the concept of geospatial information service and service chain, defines the meaning of geospatial information atomic service, discusses the quality of atomic service, and establishes the geospatial information service network diagram correlation model. Based on this model, the paper focuses on the design and implementation of semi-transparent geospatial information service chain with the workflow engine. Finally, the digital land resource management experiment result verifies the validity of this algorithm.
