Web service has become an important issue that attracts the researchers from both computer science and communication fields. SOA (service-oriented architecture) based on Web service is no doubt a perfect software engineering thought. In order to overcome some defects in the existing spatial logistics system, A new design project of spatial logistics system(More)
Remote sensing has been extensively applied in agriculture for its objectiveness and promptness. However, few applications are available for monitoring natural medicinal plants. In the paper, a multilevel monitoring system, which includes satellite and aerial remote sensing, as well as ground investigation, was initially proposed to monitor natural Rheum(More)
