A Survey of Semantic Construction and Application of Satellite Remote Sensing Images and Data

With the rapid development of satellite technology, remote sensing data has entered era big data, and intelligent processing image been paid more attention. Through semantic research ability is greatly improved. This paper aims to introduce analyze application progress from perspective semantic. Firstly, it introduces characteristics knowledge data; Secondly, concept, construction fields are introduced in detail; then, for technical study field analyzed four aspects: description understanding, segmentation, classification search, focusing on deep learning technology; Finally, problems challenges aspects discussed detail, order find directions explore.
