An Interoperable Cloud Based Geoportal for Discovery and Managment of Earth Observation Products

Abstract

This paper presents the design and development of an interoperable geoportal service for discovery and management of earth observation products (EOPs). In this service, the geoportal components are encapsulated into virtual containers that are launched into the cloud by using a microservice scheme to solve issues such as interoperability (with other systems) and implementation (over different platforms). A search microservice that analyses the preferences of end-users (settings of spatiotemporal and polygon shapes) and builds clusters of users sharing preferences was included into the geoportal for recommending/delivering, in advance, products matching with end-user preferences. The geoportal service also enables end-users to organize EOPs on-the-fly by using spatiotemporal parameters. A prototype of this service was implemented in a private cloud and connected to a satellite imagery repository of an antenna (ERIS) managed by Mexican Space Agency in a proof of concept. Learned lessons and performance assessments are described through an experimental evaluation with real users' participation. AUTHORSDante D. Sánchez-Gallegos is a master student at

A containerized service for clustering and categorization of weather records in the cloud

“…Basically, the first approach of this service was developed following the stages depicted in Figure 2, where the records are acquired and preprocessed to obtain useful data for a processing module, which performs a distributed clustering [8] with these data. The results of such a processing procedure are exposed as a service by a REST API that is automatically consumed by a geoportal (client) [9].…”

Open Community-Based Crowdsourcing Geoportal for Earth Observation Products: A Model Design and Prototype Implementation

“…It is considered as the most visible part of SDI and the entry point to it [6,7]. Due to the key functions and unique characteristics, and high demand for Earth observation (EO) products (raw and processed imagery), along with the general-purpose geoportals, the specialized geoportals have been designed and implemented exclusively for EO products [8][9][10].…”
