In April 2019 Wasat launched Jupyteo.com service: IDE environment, based on the popular Jupyter Notebooks technology, focused on processing of EO data in the cloud. Users gain access both to data sets and to functions useful for their processing, visualization and sharing. The main advantage that distinguishes this product from other tools is, apart from using ready-made algorithms, the ability to quickly and easily create users’ own algorithms or scripts. As a result, the data processing can be controlled strictly at every stage and in a formula adapted to any user needs. Although the basic programming language in Jupyteo is Python, it is possible to create code in other languages by launching additional engines offered by the integrated Jupyter Notebooks functionality. Jupyteo by default also offers the ability to create scripts in R, Scilab, Bash and indirectly - by launching the "magic cells" technology – it gives access to JavaScript programming capabilities.

Using the Jupyteo environment comes down to logging in to a Jupyteo account and automatically launching the web service. A user gains access to his own separate virtual environment based on Docker virtualization technology. There is a fully functional application at the user’s disposal along with the disk space for data storage. Work can be started by opening one of many provided scripts that are called notebooks in this system or by creating one’s own script from scratch. Regardless of the chosen programming language, an algorithm can be divided into parts called cells, each of which can be run separately. The created script source code contained in a single cell can be run online by issuing the "run cell" command or pressing the Ctrl-Enter combination. It is also possible to run all cells at once as the entire programme, depending on the user's preferences. The result of processing from each cell is visible directly below it and is presented in a text or graphic form, depending on what value is given as an output. The programme created this way can be saved as a script in a *.ipynb file, whose internal format is JSON. It will be saved to a user's account and can be launched at any time or downloaded to a home computer.

The map component is a feature that distinguishes Jupyteo and adapts it to the needs of community interested in processing EO data. The side panel on the right side of the screen is divided into tabs. One of them provides a map, which allows to search EO data and to automatically present the results of the processing. Its functionality has been taken from popular GIS systems. Thus, any result of the algorithm in a form of spatial data can be added to a map on an ongoing basis. These can be raster data formats like PNG, JPG, BMP, vector formats such as GeoJSON or services like TMS or WMS. A user has an option to create, launch and share his own WPS service that processes data and sends results to a specific location or to use the results of data processing services from other providers.

Another useful feature of Jupyteo is the ability to create code snippets that can be reused at any time after saving. A user can find a set of ready-made snippets in the "Snippets" tab on the side panel.

Jupyteo also provides the ability to search spatial data services by using functions placed in the side panel toolbar. After indicating the area and entering search parameters, a user will get a result in the form of ranges of found materials visualized as a graphic layer on the map. Each object representing the single range has attributes that allow to read metadata of the material and download or connect it to one’s own algorithm.

As already mentioned, a user of Jupyteo gets his own virtual environment, which gives the possibility of quite extensive interference and control over the installed software components. It is possible to switch to terminal view at any time, which gives direct access to the virtual system shell. One then can add or remove libraries on which Jupyteo is based and customize the system's functionality to suit user's needs. A user can also make other changes within the installed applications or additions of the system platform itself and configure it for strictly defined needs. Jupyteo has a built-in text editor through which a user can make changes to any file saved on his account. All files can be freely downloaded, placed on the server or shared with other users.

Jupyteo is intended for advanced users since, due to the programming-based approach, it offers immense opportunities to work with data, to process and modify it. Thanks to an access to the shell it is also highly flexible, allowing free configuration. Although it is an online tool placed in a virtual operating system and accessible via a web browser, working with it is similar to working with a desktop application.

If you want to use the service, please go to www.jupyteo.com and register using your Github account. As part of the Jupyteo offer, a user can get free trial access to a fully functional platform. In near future a paid version will be available allowing unlimited use of the Jupyteo environment.

The BigDataCube project, supported by the German Federal Ministry for Economic Affairs and Energy, aims at advancing the innovative datacube paradigm – i.e., analysis-ready spatio-temporal raster data – from scientific into commercial data centers. To this end rasdaman, “the worldwide leading” (ESA, 2017) datacube technology, is getting installed on the public Sentinel hub CODE-DE as well as in the commercial cloud environment of cloudeo AG. A specific new challenge on which BigDataCube focuses is versatile role-based access control on datacubes, configurable down to the level of single pixels.

Under the lead of Jacobs University the team of rasdaman GmbH (datacube backend), cloudeo AG (commercial geo cloud), and DLR (weather and ocean analytics tool) collaborate on these services. On CODE-DE, the datacube service is going to complement the batch-oriented, Hadoop-based service of CODE-DE with interactive spatio-temporal viewing, fusion, and analytics services on Sentinel satellite imagery, based on the open OGC standards.

At this stage, the cloudeo datacube and the DLR analytics tool on top of rasdaman are operational, and so is the precursor version of the CODE-DE datacube service. This precursor has been established while CODE-DE is preparing the infrastructure for the datacube engine. Based on sample Sentinel 1 and 2 timeseries it offers a broad set of access, formatting, filtering, processing, and general analytics functionality through a variety of common Web clients.

Information Society Services

In accordance with Clause 5 of European Parliament and Council Directive 2000/31/EC, dated 8 June 2000, we hereby inform you that the European Association of Remote Sensing Companies is an international non-profit association, AISB No. 0447.243.442, with registered offices at 26, Rue Beranger, 1190, Brussels, Belgium (VAT number BE 0447243442).

Trimble Unity enables customers to monitor real-time operations, deploy smart meters, assess the condition of assets, reduce leakage and non-revenue water (NRW), and locate and map critical infrastructure using Trimble high-accuracy GNSS mapping technologies.

Version 3.8 extends the platform’s capabilities to include proactive asset performance monitoring with the integration of Trimble Telog wireless Internet of Things (IoT) remote monitoring instruments and data.

A significant benefit of Trimble Unity version 3.8 is the ability to pair it with Trimble Telog wireless, battery-powered remote monitoring instruments.

Used together, Trimble Unity with Trimble Telog instruments offers a comprehensive suite of water, wastewater and storm water asset performance management solutions that include monitoring and management of water level, flow, pressure, water hammer, rainfall, water quality, pump stations and many others items and parameters on remote water and wastewater networks.

This new version provides customers with situational awareness of water and wastewater utility asset performance—offering a single view of remote monitoring data, performance measurement reports, GIS, operational data, asset conditions and events. Trimble Unity’s mobile application can be used to automate and simplify wireless monitoring instrument site deployments.

Telog wireless remote monitoring instruments may be configured to measure and report data and alarms as often as needed. The new version includes rich GIS visualization tools to view and analyze wireless remote monitoring data for a single site or aggregated data from multiple sites.

These new capabilities enable water utilities to enhance asset performance and customer response as well as collect timely data from the field to support decision making and regulatory compliance.

“Utilities are looking for ways to proactively manage their networks but are faced with challenges around the lack of data on distribution and collection network performance and asset condition,” said Rami Naber, product manager for Trimble Water.

“Trimble Telog wireless remote monitoring instruments are used by over 3,000 customers throughout North America and now Trimble Unity 3.8 can collect authoritative data from these instruments. The power of this combined solution is that it provides customers with situational awareness of network operations, empowering users with advanced workflows and tools to measure and improve network performance so they can shift to a proactive smart water management operating model.”

Trimble Unity Version 3.8 is available now through the Trimble Water Division and its authorized distribution partners. For additional information on Trimble Unity, visit.

MARKET DEVELOPMENT

Our first market development priority this year is focused on International Financial Institutions and on April 12th, our secretary general visited the World Bank along with a delegation of 25 European service providers led by ESA. The goal was to initiate 12 projects selected under the ESA EOMD programme where service providers are engaged directly in WB projects and for EARSC to show how it could help in developing stronger links in the future. The World Bank welcomed the participation of EARSC and encouraged us with the idea that we can act as a neutral facilitator to help broker future opportunities.

Meanwhile, Eopages is nearing the point where it will go live and an early version was shown to the World Bank. This new brokerage platform will help potential customers find suppliers whilst service providers will be able to promote their products. Watch out for a mail that invites you to enter your own product promotional material. Some entries are already being made. In conjunction with the World Bank visit we gathered 12 examples of products that could be used in development projects and these are all being converted into an eopages form.

Our second priority for 2011 is the oil and gas industry and improving links with the EO service provider Community. The OGEO working group, where EARSC provides the secretariat, is guiding the initiative under the chairmanship of Richard Eyers at Shell. As well as developing stronger links between the two industry sectors (through meetings and workshops) we are putting in place a Community tool and seeking to establish a joint industry project. The OGEO web-portal will be available later this summer.

POLICY DEVELOPMENT

We published a position paper on “Exploiting GMES Operational Services”. This has been widely distributed and well received. It raises three key issues for the future for which we plan to develop more detailed proposals. The first priority is linked to the implementation of a data policy for GMES and a workshop is being planned. Those interested to join the working group on this topic should inform the secretariat and keep June 17th in mind as a possible date on which a workshop could be held in Brussels.

INTERNAL ACTIONS

Quality Scheme: Please also note that we are anticipating with ESA the possibility to hold a workshop in the previous afternoon ie 29th June starting at around 16h00 on the topic of certification and standards. ESA has been carrying out some work on this topic and it is planned to present this to the workshop before seeking reaction and views through an open interaction.

Data licensing: Would members be interested in a workshop organised to discuss aspects of EO data licensing and distribution? It could help legal advisors become familiar with EO data issues and look/share at best practice across the various service providers. This wk could also be an exchange with US companies and legal specialists.

RELATIONSHIP

In April, meetings have been held with Eurogi, Nereus, ERRIN, ESOA and Eurospace. In a wider field, we also met with the US Alliance for Earth Observation and the Centre for Spatial Law (Kevin Pomfret). We are exploring ways to work more closely with all these groups and as an example we are invited to present the Association to the ERRIN transport group when they next meet in May and we are discussing with the CSL to organise a workshop to look at the legal aspects and share best practise across the atlantic on data licensing. For information, Nereus and ERRIN both bring together representatives of European regions; Nereus focused on space users and ERRIN on research and innovation.

EARSC has been invited to be a member of the Joint Advisory Board for two EC sponsored GMES networking projects Graal and Doris. Our Secretary General will participate to the first meeting on June 9th.

FORTHCOMING MEETINGS

AGM: 30th June Brussels

EARSC AGM will take place on 30th June in Brussels. This year EARSC will organize after the AGM, two separate seminars, the morning seminar is dedicated to the “Current status of operational GMES” while the afternoon seminar will be focus on the “EO service markets”. Key stakeholders will be invited to give an overview of these topics. There will also be a buffet reception giving an opportunity for more informal discussions with EARSC Members including the Executive Board. If for any reason you will not be able to attend the Annual General Meeting and want to have your position represented, please do not forget to give the power of representation by the mean of a proxy. EARSC is also opening an invitation to its members to participate by nominating candidates for Directors.

EARSC will be present at the following workshops:
