PROBA-V continuity survey

The PROBA-V mission will most likely be extended to March 2020. To prepare for the time after that (using Sentinel-3), we want to ask you a few questions. This will take about 5 minutes of your time.

Question Title

1. How important are PROBA-V Level 1C data to you?

I sometimes use it

I never use it

Question Title

4. Why do you use your preferred PROBA-V product?

Because of its spatial resolution

Because it is a composite image

Because it is raw data

Because it is part of a long time series (1998-today)

Because of the repeat rate
