Google Earth Engine: A Global Analysis and Future Trends

Abstract

The continuous increase in the volume of geospatial data has led to the creation of storage tools and the cloud to process data. Google Earth Engine (GEE) is a cloud-based platform that facilitates geoprocessing, making it a tool of great interest to the academic and research world. This article proposes a bibliometric analysis of the GEE platform to analyze its scientific production. The methodology consists of four phases. The first phase corresponds to selecting “search” criteria, followed by the second phase focused on collecting data during the 2011 and 2022 periods using Elsevier’s Scopus database. Software and bibliometrics allowed to review the published articles during the third phase. Finally, the results were analyzed and interpreted in the last phase. The research found 2800 documents that received contributions from 125 countries, with China and the USA leading as the countries with higher contributions supporting an increment in the use of GEE for the visualization and processing of geospatial data. The intellectual structure study and knowledge mapping showed that topics of interest included satellites, sensors, remote sensing, machine learning, land use and land cover. The co-citations analysis revealed the connection between the researchers who used the GEE platform in their research papers. GEE has proven to be an emergent web platform with the potential to manage big satellite data easily. Furthermore, GEE is considered a multidisciplinary tool with multiple applications in various areas of knowledge. This research adds to the current knowledge about the Google Earth Engine platform, analyzing its cognitive structure related to the research in the Scopus database. In addition, this study presents inferences and suggestions to develop future works with this methodology.

Framework to Create Dataset for Disaster Behavior Analysis using Google Earth Engine: A Case Study in Peninsular Malaysia for Historical Forest Fire Behavior Analysis

“…In this work, GEE is leveraged as the primary big data platform for accessing remote sensing data, providing a robust foundation for meaningful analysis. It has been widely adopted for various tasks, showcasing its versatility [27][28][29][30][31]. The significant increase in the availability of publicly accessible remote sensing data [13] presents a promising opportunity for research and analysis.…”

Construction of Remote Sensing Indices Knowledge Graph (RSIKG) Based on Semantic Hierarchical Graph

“…As the most prevalent cloud-based geospatial science platform, Google Earth Engine (GEE) [26] provides extensive remote sensing data and a rich set of tools for index analysis. It significantly reduces the barriers to entry for remote sensing research [31]. However, while platform software can calculate common indices, it is not keeping up with the rate at which index development grows.…”

Tracking the Effects of Mangrove Changes and Spartina alterniflora Invasion on Soil Carbon Storage: A Case Study of the Beibu Gulf of Guangxi, China

“…Some researchers used the CCDC algorithm to track the loss and recovery of mangroves in six natural reserves in the Guangdong-Hong Kong-Macao Greater Bay Area, proposing a mangrove-protection evaluation system [12]. Due to the extensive data storage and complexity of the algorithm, the emergence of remote sensing cloud platforms has provided new research perspectives for addressing these challenges [13]. Google Earth Engine (GEE) is a free and open cloud platform capable of processing geospatial big data [14].…”
