Pixel Twins
EO data
▪ Area-wide information
▪ Possible data (Sentinel-2 L1C)
• Short wave infrared composite (SWIR)
• Normalized Difference Moisture Index (NDMI)
• Normalized Difference Vegetation Index (NDVI)
IoT data source
▪ Local data
• Position/Pixel of sensor
▪ Select important data
• E.g. soil moisture data
Vienna, 12-13 June, 2023 | #FIWARESummit www.fiware.org
How it works
2. Draw polygon
1. Find region of interest
3. Create pixels
4. Apply EO data
5. Merge with IOT data
