1 Ера "великих даних" та інноваційні проекти в супутниковому моніторингу Проф. д.т.н. Куссуль Наталія Миколаївна, к.т.н. Колотій А.В., М.С. Лавренюк Інститут космічних досліджень НАН України та ДКА України 1

2 Who we are: Current Expertise & International Activities Informational Technologies Department at Space Research Institute NASU-SSAU Active participation in the Working Group on Information System and Services (WGISS) of the Committee on Earth Observation Satellites (CEOS). Participation in international collaborative activities within GEO Working Plan Disaster monitoring, GEOGLAM UN-SPIDER RSO, Geospatial center of World Data System

3 Satellite data - SAR Radarsat-2: Nominal Scene Size - 50x50 km 2 Repeat cycle - 24 days Cost - more than 4000$ per scene Sentinel-1: Nominal Scene Size - 250x250 km 2 Repeat cycle - 12 days More than 500 scenes in 2015 for Ukraine territory Cost - free 3

4 Satellite data optical RapidEye: Swath Width 77 km Revisit time: Daily (off-nadir) / 5.5 days (at nadir) Cost non free Sentinel-2: Swath Width 100 km Revisit time: 10 days Sen2Agri: Sentinel-2 National Cost - free level Demonstration Landsat-8: Scene Size - 185x180 km 2 Repeat cycle - 16 days Cost free Proba-V: Swath Width 2250 km (full field of view) Cost free 4

5 Global Initiatives on Earth Observations: Ukraine, cooperation Stategic GEO plan створення системи систем GEOSS ( ) Agromonitoring Program GEOGLAM (JECAM) Initiative on validation of global land cover with 30 m resolution (2016) Development of services on GEOSS Common Interface (GCI) ESA Copernicus Program Sen2Agri Project (country level demonstration) 5

6 International agromonitoring projects GEOGLAM & JECAM initiatives Winter Wheat Yield Forecasting for the whole Ukraine Crop classification using SAR & optical data Validation of global products within JECAM Ukraine test site ESA Sentinel-2 for Agriculture ( ) Champion User, Test site, Product developer Take5 Initiative: SPOT-5 observes Ukraine every 5 days to simulate Sentinel-2 Within FP7 ImagineS (Implementation of Multi-scale Agricultural Indicators Exploiting Sentinels) ( ) Validation of global satellite products (by ESA VALERI protocol) FP7 SIGMA project ( ) Assessing environment impact of agriculture

7 PROJECTS General approach to agriculture monitoring JECAM Activities Local Scale Field level 100m 1km Mid-Scale NUTS3 NUTS2 50x50 200x200 km Large Scale Whole Ukraine 1000x1000 km Validation Product development Operational implementation FP7 ImagineS ESA Sentinel-2 for Agriculture FP7 SIGMA

8 Land cover map with use of different satellite data (2015) Kiev Region Satellite Overall accuracy, % L-8 + S SENTINEL LANDSAT Satellite data: 4 scenes of Landsat-8 15 scenes Sentinel-1 In-situ data: 547 samples (train and test) Class Official stats (1000 ha) Classification results (1000 hа) Winter wheat Winter rapeseed Maize Sugar beet Sunflower Soya

9 Sentinel-2 for Agriculture Sen2-Agri launched by ESA, as a major contribution to the R&D component of the GEOGLAM initiative and to the JECAM network activities. Sentinel-2 Pair of satellites, carrying each one an optical payload with visible, near infrared and shortwave infrared sensors; 13 spectral bands (4 bands at 10 m, 6 at 20 m and 3 at 60 m) with a 290 km swath, Revisit in 16 days (with two units 5 days) 9

10 4 Sen2-Agri products and their respective timing In line with the GEOGLAM core products Monthly cloud free surface reflectance composite at 10-20m (after initialization of the system by cloud free acquisition) Binary map identifying annually cultivated land at 10m first produced at the user-defined mid-season, then updated every month EARLY AREA INDICATOR EARLY AREA INDICATOR Vegetation status map (NDVI, LAI) at 20m delivered for each cloud free observation, then smoothed over 3 dates and Crop type map at 10m for the 5 main crops first produced at the userdefined mid-season and, produced again at the end of the season

14 PROJECT H2020 ERA-PLANET ERA-PLANET THE EUROPEAN NETWORK FOR OBSERVING OUR CHANGING PLANET H2020 Topic SC : Strengthening the European Research Area in the domain of Earth Observation The goal of ERA-PLANET is to strengthen the European Research Area in the domain of Earth Observation in coherence with the European participation to Group on Earth Observation (GEO) and Copernicus. The expected impact is to strengthen the European leadership within the forthcoming GEO Work Plan. 35 organizations with 11 milling budget by EC (European Commision) 14

15 Strands of ERA-PLANET 1. Smart cities and resilient societies urban growth, air quality, disasters, health, contaminated sites; 2. Resource efficiency and environmental management water, energy, biodiversity, food security; 3. Global change and Environmental treaties climate forcing, coastal zone, resource depletion; 4. Polar areas and natural resources Results of human activity 15

16 Implementation and Euro Integration In the basis National program GEO-Ukraine EC give additional funding for the Project - 50% of National Program 16
