FAQ
What people usually ask.
Can I follow the site between flights?
Yes. Add satellite imagery and vegetation indices such as NDVI via WMS, and see how things change between drone surveys.
Can I use results that are already processed?
Yes. Import them and organise them by date in the same project.
Can the team look at the history?
Yes. Anyone with access to the project sees every date, at the access level the administrator sets.
