The NextGEOSS project presents a new European vision of GEOSS data exploitation for innovation and business. It focuses on a fundamental change, where we optimize the connectivity of the European and global Earth Observation data centers with new discovery and processing methods. The NextGEOSS platform offers easy and seamless access to all relevant data repositories, as well as efficient operations (search, retrieval, processing/re-processing, visualization and analysis). It is an Earth Observation Data Hub to help develop and deploy new services requiring a wide variety of data sources, and it creates a solid foundation for capacity building through Platform services aimed at supporting GEOSS community platforms.
What is the NextGEOSS project?
What is the NextGEOSS platform?
It is an European platform providing GEOSS communities with a hub for Earth Observation data, where the community users can connect to access data and deploy EO-based applications. The concept revolves around providing the data and resources useful to Community portals, together with Cloud processing resources, seamlessly connected as an integrated ecosystem for supporting applications.
The NextGEOSS Data Hub is built on top of a powerful data management system (CKAN), that provides tools for publishing, sharing, finding and using Earth Observation data.
From each community, NextGEOSS Access Enablers allow to create ‘community hubs’ with selected data buckets, in order for community portals to exploit the data needed from different providers. The selected data is extracted from the relevant distributed research and operational data infrastructures, and ‘broadcasted’ to access points dedicated to community applications. The NextGEOSS Cloud Appliances then deliver back to the community hubs the new products and analysis results, that have been processed on a scalable Cloud Computing infrastructure. Community Portals register the selected products and services to the GEOSS registries, together with the respective data and service policies.
Which are the main goals of NextGEOSS?
The main goals of NextGEOSS are the engagement of communities of providers and users, by bridging the space between them. NextGEOSS facilitates the access to the Earth Observation data and provides a virtualized work environment to deploy EO applications and services. The NextGEOSS platform will allow the integration of the new data exploitation capabilities within the community applications. The NextGEOSS platform brings the data processing applications close to the data, and it does it with no lock-in and with full support of interoperable, multi-stakeholder, distributed systems.
How can I access and discover data via the NextGEOSS Data Hub?
The Data Hub is built on top of a powerful data management system that allows the users to find data with queries like semantic search (e.g. search the word “Mediterranean sea”). There is a NextGEOSS catalogue where the users can discover data and check the EO products that correspond to the query performed. In this catalogue, users are able to visually check data products Quicklooks and the regions covered by the data. The NextGEOSS Data Hub also offers to the users a standard OGC OpenSearch interface. This interface is used by the integrated applications to perform queries to the NextGEOSS catalogue, which automatically retrieves dataset files references, exploitable by the Cloud processing services.
Which EO data can be found in the NextGEOSS Data Hub?
The main data that is being harvested by the NextGEOSS Data Hub is the data from the Copernicus Programme and its respective Core Services (e.g. Sentinel data, Copernicus Marine Environment Monitoring Service, Copernicus Atmosphere Monitoring Service, etc.). However, data from other open data providers can be found in the NextGEOSS Data Hub, such as Proba-V or GOME-2 data.
What are the main advantages of bringing my application to NextGEOSS?
The main advantages of bringing your application to the NextGEOSS platform are the easy access to Earth Observation data and the capability of processing that data in a scalable cloud-based system. Today, with the huge amount of data and the size of the high resolution EO products, it is not possible to transfer data and process it locally. By bringing an application to the platform, the user will be able to easily discover data over his area of interest, and will have the processing power to handle that data without the investment in a local processing system.
Which are the innovative features provided by NextGEOSS?
In the NextGEOSS platform, beyond the easy access to the data and the elastic data processing capabilities, the registered users are also able to rate all the data within the NextGEOSS Data Hub, and to provide and get feedback about each dataset.
Another innovative feature is the NextGEOSS Analytics Engine that helps users taking decisions. With this tools, users are able to check, for example, the availability of the NextGEOSS Services and other usage statistics, all the statistics about the data in the NextGEOSS Data Hub (e.g. quality information, usage statistics), keywords and tags that appear more times in the search results and many other statistics.
How do I deploy my application in NextGEOSS?
When a new user starts integrating an application in the NextGEOSS platform, a development environment is made available to deploy and test the algorithms. The user has access to tutorials and documentation helps during the integration process. The development environment is basically a single node of a cloud cluster (VM with 2 CPUs). This guarantees that the application will work properly in the production environment (flexible cloud cluster).
How do I get support in NextGEOSS?
The NextGEOSS support system intends to provide different levels of support. There is a support system level dedicated to registered users (during their integration and exploitation tasks) and another level dedicated to help organizations and people interested to join NextGEOSS.
For the registered users, a service desk is available for all the questions/issues related with the platform, as well as for their application integration activities.
If you are interested to join, and you do not find the answer to your question in this FAQ, please contact us through the “Contact us” page.
What is the process for going from the development environment to the production environment?
The process is simple and supports automation for scalablity. After the integration, test and validation of a new data processing application in the development environment, the validated application package is referenced on the Platform Repository, and can be burst onto a pool of production machines, through the Platform Cloud APIs.
Is the NextGEOSS platform ready to be used?
During the consolidation stage of the platform, and at least for the coming year (2018), the system is being developed and tested with the integration of selected Pilot applications. The inclusion of communities and services as new Pilots, already during the consolidation phase, is a possibility offered by NextGEOSS.
How much does it cost to be a test pilot in the NextGEOSS platform?
There will be no costs applied by NextGEOSS. The NextGEOSS infrastructure and support to new incoming Pilots will be funded by the project, during the consolidation phase of the project. The main cost for a newly selected Pilot is expressed in terms of time and manpower required on the submitter for the Pilot integration, test and operation activities.
How can my service become a new incoming pilot?
The candidate service should use the “Pilot Engagement Questionnaire” form, in order to get in touch with the NextGEOSS Support team, and explain the general ideas and study area of the application (the subject should be NextGEOSS Pilot idea). The support team will contact the candidate with additional questions and/or suggestions to maximize the respective benefits and minimize the investments. If the candidate service is considered a good example to be an incoming pilot, and is happy about expected benefits, the instructions to start in the development environment will be sent via email.
What is the procedure if my service is selected to be an incoming pilot?
If the candidate application is selected to be an incoming pilot and the expected benefits for the service are clear, the integration process will be automatically triggered. The support team will contact the people responsible for the service integration and provide detailed instructions to create an account in the NextGEOSS User Management system and access to the development environment. Integration tutorials are also made available.
