Modern Satellite Systems
About Sentinel-2
Constellation of Twin Satellites: Sentinel 2A and 2B
From European Space Agency
Sentinel 2A was launched in December, 2015
Sentinel 2B is scheduled to be launched in March 2017
Twin Satellites Sentinel 2A and 2Bgoing to be placed at an interval of 180 degrees
Current Revisit Period is 10 Days
After the Launch of Sentinel 2B the temporal resolution will be increased to 5 days
About Sentinel-2
Swath is 290 Km
The satellites are equipped with the state-of-the-art MSI (Multispectral Imager) instrument, that offers high-resolution optical imagery
12 Spectral Bands
Spatial Resolution of 10m, 20m and 60m
Consists of Red Edge Bands which helps in early identification of certain crops
NIR and SWIR Bands also present
About Sentinel-2

Presentation Outline
Major Advantages
Sentinel-2
o Available Free of Cost therefore saves Input Cost
o Optimal Resolution of 10m (VNIR), suitable for Crop Mapping
o High Temporal Resolution of 10/5 Days, very good for Continuous
Monitoring
o Variety of Spectral Bands help in manifold analysis of Crop
o Swath of 290 Km helps in covering larger areas with lesser images
Major Advantages
Geoanalitika.AGRO
o It is a Cloud-based Solution, therefore no GIS Infrastructure Required
at the client’s end
o Very less human intervention, so chances of biasness is negligible
o Has the capability to process different types of images through API
o Variety of inputs like satellite images, meteorological data,
topographical data etc are used
o Client can visualize individual satellite images used for processing
o Algorithms developed by experts in the field of Agriculture and Image
processing
Major Advantages
Geoanalitika.AGRO
o Maps of cultivated areas, agricultural land structure, harvested fields are
generated
o Variety of Vegetation Indices are created which helps in assessing the crop
health from different aspects (not only NDVI based)
o Crop Health Map is created which shows the spatial distribution of crop
performance
o Maps of Crop Growing Condition can be visualized
o The analytical interface helps in viewing different statistics, graphs and reports
from Farm Level to any other Administrative Level
o Helps in decision making
