Abstract:

With the development of large space-based and ground-based observational technologies,the volume,output rate and complexity of astronomical data rapidly increase.The astronomy steps into a new data-intensive era.The characteristics of astronomical data were represented.The limitations of traditional astronomy were analyzed.The necessity and research direction of developing astrostatistics and astroinformatics were put forward.As a typical astronomical application,the operation and applications of LSST were introduced.The organizations related to astrostatistics and astroinformatics were summarized.The present situation and problems of public education about this respect were analyzed.All these were provided as references for the healthy development of big data in astronomy.

Key words: astronomical big data, astroinformatics, astrostatistics, survey
