Progress and Trends in the Application of Google Earth and Google Earth Engine

Earth system science has changed rapidly due to global environmental changes and the advent of observation technology. Therefore, new tools are required monitor, measure, analyze, evaluate, model data. Google (GE) was officially launched by in 2005 as a ”geobrowser”, Engine (GEE) released 2010 cloud computing platform with substantial computational capabilities. The use these two or platforms various applications, particularly used remote sensing community, developed rapidly. In this paper, we reviewed applications trends GE GEE analyzing peer-reviewed articles, dating up January 2021, Web Science (WoS) core collection using scientometric analysis (i.e., CiteSpace) meta-analysis. We found following: (1) number articles describing increased substantially from 2006 530 2020. much faster than those concerned GE. (2) Both were extensively community multidisciplinary tools. covered broader range research areas (e.g., biology, education, disease health, economic, information science) appeared journals GEE. (3) shared similar keywords “land cover”, “water”, “model”, “vegetation”, “forest”), which indicates that their application is great importance certain areas. main difference emphasized its visual display platform, while placed more emphasis on big data time-series analysis. (4) Most undertaken countries, such United States, China, Kingdom. (5) an important tool for analysis, whereas auxiliary visualization. Finally, merits limitations GEE, recommendations further improvements, summarized perspective.
