Workshop «Satellite data application for the monitoring of territories»

Workshop «Satellite data application for the monitoring of territories»

On October 24, 2018, in the framework of XVII Annual strategic planning leaders forum of the regions and cities of Russia, a workshop «Satellite data application for the monitoring of territories» was held in St. Petersburg.

The workshop was organized by BalticSatApps project partners: Committee on IT and Communications, Russian-European Innovation Partnership, St. Petersburg Institute for Informatics and Automation of RAS and Finnish Meteorological Institute. The event took place at St. Petersburg Democenter.

At the seminar the staff of LITSAM Viacheslav Zelentsov and Ilya Pimanov presented a report on the following topic: «Copernicus data: key features of access and processing for Russian users».

The report reviewed Copernicus data available for the territory of Russia – satellite images and thematic products created on their basis.

Particular attention was paid to the experience of using satellite data (including Sentinel images) to monitor the emergencies, land cover, agriculture and other objects within the LITSAM projects.

The practical part of the seminar included the downloading of Sentinel-2 data for the territory of the Leningrad region and demonstration of the possibilities for their processing by the means of open-source software.

IGARSS 2018

On July 22-27, 2018 the world’s largest forum on the topic of remote sensing International Geoscience and Remote Sensing Symposium (IGARSS 2018) took place in Valencia (Spain).

The forum is annually organized by IEEE Geoscience and Remote Sensing Society.

On section «Advances in Model-data Integration and Assimilation» LITSAM junior researcher Pimanov Ilya presented the following report:

Software suite for creating downstream applications and thematic services on the base of remote sensing data processing and integrated modelling (Authors: Zelentsov V.A., Potriasaev S.A., Pimanov I.Yu., Mochalov V.F.).

During the conference, a meeting was held with colleagues from the National Research Council of Italy and the questions of further cooperation were discussed.

InMotion project meeting at SPIIRAS

InMotion project meeting at SPIIRAS

On June 23 – July 9, 2018, in the framework of ERASMUS+ project «InMotion – Innovative teaching and learning strategies in open modelling and simulation environment for student-centered engineering education» the 1st  International Open Summer School 2018 was held in St. Petersburg.

This event was organized by St. Petersburg State Marine Technical University, Peter the Great St. Petersburg Polytechnic University and St. Petersburg Institute for Informatics and Automation of the Russian Academy of Sciences.

On July 6, 2018, the project participants and more than 40 students from partner universities visited SPIIRAS, where LITSAM representatives made several reports on the topic of laboratory’s current scientific activities.

The head of LITSAM Professor Sokolov B.V. spoke about modern technologies of complex objects and systems modeling . Chief researcher, Professor Zelentsov V.A. reported about technologies of designing and using thematic services based on modern and perspective platforms. As an example of practical implementation of such technologies Professor Zelentsov V.A. and junior researcher Pimanov I.Yu. showed the work of operational river flood monitoring and forecasting system «Prostor» created under the Russian Science Foundation grant. Junior researcher Ponomarenko M.R. made a report about the possibilities and the experience of using remote sensing data for verification of monitoring and forecasting results.

During the seminar project partners discussed the current stage of the project and the prospects for further cooperation.

Another stage of the project is completed

Another stage of the project is completed

On June 15, 2018, the meeting of the commission from Committee on Communications and IT of the Leningrad region was held at Regional navigation information center in order to evaluate the results of the 3rd working period of the project “Development of the Leningrad Region Spatial Data Fund”.

LITSAM senior researcher, Candidate of Technical Sciences Semyon Potriasaev and junior researcher Ilya Pimanov took part in the meeting and successfully demonstrated the obtained results.

LITSAM presented the developed web application for georeferencing the objects of the terrain and the improved module for calculating and building connection between spatial objects in spatial data fund (SDF).

As a result of the meeting the commission decided to continue the work on developing Leningrad Region Spatial Data Fund.

Testing of the operative flood forecasting system

Testing of the operative flood forecasting system

Operational river flood monitoring and forecasting system «Prostor» created under the Russian Science Foundation grant 17-11-01254 is currently being tested on the part of Northern Dvina river – from the city of Velikiy Ustyug to the city of Kotlas.

The principal key feature of the “Prostor” system is full automation of all stages of operation, including:

  • loading of data from hydroposts (automated hydrological complexes) and meteorological data;
  • generation of the contours and depths of flooding;
  • publication of created contours on the GIS platform;
  • identification of objects inside the flooded area;
  • notification of interested persons.

Automation of processes and friendly simplified interface provides easy intuitive operation with the system even if the user is not a specialist in the field of hydrology, data processing, information and GIS technologies.

Every hour the system forms 24-hour forecast of flooded areas and depths for 24-48 hours ahead in the operational mode. The following operation scenario is also available: what happens if water levels at hydroposts reach the particular value.

The images from Russian satellite Resurs-P, European satellites Sentinel-1 and Sentinel-2 are constantly being loaded into the system – processed and published images give the opportunity to assess the accuracy of the modeling and quickly refine the parameters of models.

The potential users of the system are local administrations, regional hydrometeorological services, emergency services, services for population protection. Currently, they evaluate the test version of the system.

The system “Prostor” is focused, first of all, on the regional level of use where a highly detailed analysis of the available source data (such as digital elevation models, riverbed characteristics, permanent and temporary data from hydroposts, information about specific infrastructure in potentially flooded areas etc.) is necessary and requirements to the accuracy of simulation results used in the planning of protective and rescue measures are particularly high.

To work on the project, a team of specialists has been formed, combining advanced Russian scientific schools of both hydrological / hydrodynamic modeling and automatiс modeling, integrating heterogeneous information resources and creating modern information systems and services. This determines the uniqueness of the system and its truly interdisciplinary nature which has no analogues in Russia in this field of projects implementation.

At the previous stages of the research a successful testing of the system based on historical data was carried out. Currently, the most complex mechanisms for responding to hydrological phenomena (primarily associated with ice jams) are being worked out in operational mode.

The system and its preliminary test results were presented at the St. Petersburg Digital Forum and aroused great interest of specialists.

The “Prostor” system is a completely Russian technology based on open source software. The following Russian software systems are applied for the system operation: «STREAM 2D» (Certificate of software registration № 2014612181), «ECOMAG» (Certificate of software registration № 2013610703) and also the systems developed at LITSAM – «UnisonPro» (Certificate of software registration № 2016660672) and «RegionView» (Certificate of software registration № 2016612635).
