I realise this is probably a fairly basic question.
I need to download high resolution TIFF imagery layers from Botswana 2015-2018. I’ll be using these aerial images to create habitat polygons as raster data which I will use for analyses afterwards.
Can someone please tell me the best way to download these on sentinel?
depending on what you count as “high resolution”. If 10-meter resolution imagery coming from Sentinel-2 is enough, it is probably easiest to try EO Browser and choose “Analytical download”, see: https://www.sentinel-hub.com/explore/eobrowser
If you need higher resolution data, you would need to buy some commercial imagery. For the use-case you describe, it is probably easiest if you use Geocento’s imagery search.
