Test set features description
26 Jun 2025, 10:50 · 2
Could you please share more information about the features in the test set, especially:
- What is the format of the `time` feature? It's not clear what 59:22.9 means, for example.
- Is the `nir` feature in the test set the Sentinel2 band B8, is `nir08` band B8A, and are `swir16` and `swir22` bands B11 and B12, respectively?
B02: blue
B03: green
B04: red
B05: rededge1
B06: rededge2
B07: rededge3
B08: nir
B8A: nir08
B11: swir16
B12: swir22
About time - yyyy-MM-dd HH:mm:ss.SSS (Minutes,Seconds,Milliseconds)
Sentinel-2 provides data with a temporal resolution (revisit time) of 5 days, achieved by combining data from its two satellites, Sentinel-2A and Sentinel-2B.
So on average, Sentinel-2 can revisit the same location on Earth every 5 days.
This means you don't have to worry about time beyond day-level precision.
