D2.1 Report on the state of the art for Earth data models
This document describes the state of the art data models useful for storing, accessing, and processing large volumes of data (spatial information in particular). The aim of the current deliverable is to provide a solid background for the conceptual and technical solutions that will be developed and implemented in this ongoing project. This background should be understood as a state of the art analysis of the current research activity in the Earth Science related domains which includes: an overview of the existing data types and formats, analysis of the repositories that store big data, data access policies, and up to date tendencies in terms of processing large volumes of data.
D2.2 Report on Earth Observation data processing types
This document describes the main processing types that are relevant for the Earth Observation activity domains. These algorithms were identified by analyzing the state of the art articles and projects conducted by world-wide research communities. The document begins with a general classification of these processing and then it tries to customize them with use cases that can fit in the real world society. This analysis is important for the upcoming project deliverables that have to provide technical approaches for implementing such scenarios.
D2.3 Specifications for Earth data management methodologies
This document presents solutions for managing large volumes of spatial data in an optimal and easy to access manner. It starts with data models in the context of GIS related domains and it continues with a state of the art of tools and platforms focused on centralized and distributed database systems. The data management chapter also describes concepts and mechanisms related to storing, accessing, and transferring large volumes of data. Another topic that is presented is related with database management systems for Earth Data.
D2.4 Requirements and specifications for interoperability and integration of Earth data models
This document describes the requirements and specifications for interoperability and integration of Earth data models. The aim of the current deliverable is to provide a solid background regarding interoperability and integration based on standards. This background should be understood as a state of the art analysis of the current interoperability standards related to Earth Observation and includes an overview of the existing standards, web containers, solutions for web mapping of spatial data and file formats.
D3.1 Report on solutions for flexible description of knowledge extraction
This document describes the proposed solution for the representation of the Big Earth Data processing algorithms in a workflow-based approach – which constitutes one of the core elements of this project. Our chosen implementation is based on a simple, compact and intuitive description language called WorDeL (Workflow Description Language) and is aimed at maximizing the functionality reuse while providing a degree of flexibility, allowing for minimal user training efforts while at the same time offering more advanced users facilities for increasing the design efficiency.
D4.1 Study report on the high performance computing architectures
This document describes the state of the art on high performance computing architectures, which are suitable for processing large volumes of data (spatial information in particular). The aim of the current deliverable is to provide a solid background for the conceptual and technical solutions that will be developed and implemented in this ongoing project. In this document we present different solutions based on HPC processing developed in various research projects, as well the hardware and software architecture that we propose to be used in the frame of the ongoing project.
