Abstract
In recent years, Earth observation (EO) satellites have generated big amounts of geospatial data that are freely available for society and researchers. This scenario brings challenges for traditional spatial data infrastructures (SDI) to properly store, process, disseminate and analyze these big data sets. To meet these demands, novel technologies have been proposed and developed, based on cloud computing and distributed systems, such as array database systems, MapReduce systems and web services to access and process big Earth observation data. Currently, these technologies have been integrated into cutting edge platforms in order to support a new generation of SDI for big Earth observation data. This paper presents an overview of seven platforms for big Earth observation data management and analysis—Google Earth Engine (GEE), Sentinel Hub, Open Data Cube (ODC), System for Earth Observation Data Access, Processing and Analysis for Land Monitoring (SEPAL), openEO, JEODPP, and pipsCloud. We also provide a comparison of these platforms according to criteria that represent capabilities of the EO community interest.
Highlights
Nowadays, Earth observation (EO) data play a crucial role in understanding processes on our planet, enabling us to make great strides in monitoring environmental change, risk detection and urban occupation analysis [1,2]
This paper presents an overview of seven platforms and a comparison among their functionalities—Google Earth Engine (GEE) [35], Sentinel Hub (SH) [34], Open Data Cube (ODC) [36], System for Earth Observation Data Access, Processing and Analysis for Land Monitoring (SEPAL) [37], OpenEO [38], JEODPP [3], and pipsCloud [39]
The Open Data Cube (ODC), previously known as the Australian Geoscience Data Cube (AGDC), is an analytical framework composed of a series of data structures and tools that facilitate the organization and analysis of EO data
Summary
Earth observation (EO) data play a crucial role in understanding processes on our planet, enabling us to make great strides in monitoring environmental change, risk detection and urban occupation analysis [1,2]. These platforms integrate different kinds of technologies, Application Programming Interfaces (API) and web services to provide a more complete solution for big EO data management and analysis Based on this definition, this paper presents an overview of seven platforms and a comparison among their functionalities—Google Earth Engine (GEE) [35], Sentinel Hub (SH) [34], Open Data Cube (ODC) [36], System for Earth Observation Data Access, Processing and Analysis for Land Monitoring (SEPAL) [37], OpenEO [38], JEODPP [3], and pipsCloud [39].
