Abstract：The storage and depth of groundwater are important contents in groundwater resources survey. Remote sensing technology has advantages of fast data acquisition, low comprehensive cost and large observation scale. The groundwater resources assessment technology based on remote sensing has always attracted the attention of researchers, and it is also a hot and difficult issue in the field of remote sensing application research. This paper presents an overview of the application research progress of remote sensing technology in the assessment of groundwater storage and depth, and have divided the groundwater resources assessment technology into three types-single-factor model evaluation method, multi-factor comprehensive model evaluation method and evaluation method based on GRACE data auovding to their characteristics. Three conclusions are drawn. Firstly, the groundwater resources assessment technology based on remote sensing has been continuously enriched and the assessment accuracy has also been continuously improved after years of development, which can be used as an important auxiliary method for traditional groundwater resources survey. Secondly, the research on remote sensing evaluation technology for groundwater storage has developed rapidly, while these for groundwater depth have progressed relatively slowly. Thirdly, the combined use of high-temporal-spatial resolution remote sensing technology and machine learning technology, and the application of UAV remote sensing technology are future development directions of the groundwater resources assessment technology based on remote sensing.
