We provide reliable observations for 30-50% more parcels with complex shape and as small as 0.5 hectares.
Especially useful when you need to investigate polygons with low spatial variability (e.g., crop fields, forest parcels, open area mining sites), which have distinct signatures in time.
Parameter group 1: min., max., mean, median and standard deviation of the InSAR 6-day repeat pass coherence (VH, VV) generalized to present a whole polygon.
Parameter group 2: min., max., mean, median and standard deviation of the SAR backscatter (VH, VV and VH/VV ratio) generalized to present a whole polygon.

Features
The mission of KappaZeta services
It is often impossible to develop operational, high accuracy Earth observation application based only on the data from optical satellites. If clouds or smoke block the view, optical satellites are unable to capture the situation on ground. One can overcome this obstacle by adopting data from synthetic aperture radar (SAR) satellites. SAR data has another significant advantage – it contains information about the structure and water content of land cover.
ESA Copernicus Sentinel-1 is a great SAR mission and provides huge potential for the EO community. Unfortunately, its data is largely under-exploited because it is too complex to use for a large majority of potential beneficiaries. The entrance barrier for correct adoption of Sentinel-1 data is too high in sense of lacking know-how about right pre-processing. Our experience shows that most of ICT, GIS, EO, consultancy companies, and governmental users overlook SAR data because it is not economically reasonable to build the processing competence in their organization. This is the exact place where KappaZeta can make your life easier.
We take the SAR data of Sentinel-1 and refine it with science-grade processing chain. We turn images distorted by thermal noise into highly accurate analysis-ready time series of statistics and raster layers. The output we provide enables our clients to have reliable analysis and make better informed decisions in various domains.
