Hello,
I have two questions. Sorry, I don’t know if I should separate them to different threads?
-
When using the sentinelhub python package there is an option for the CRS. Let’s say I have my AOI in EPSG:4326 but since Sentinel2 L2A is natively provided in UTM (respecting the zone) is it better to reproject the geometry to UTM and then download the data?
-
When is it necessary to split the AOI (in terms of maximum area) to receive the best results regarding the spatial resolution? For example, when downloading a bigger AOI and calculating the NDWI, I receive results in 20x20m. Also, how is it possible that I receive the results of NDWI (combination of band 03 & band 08) in 20x20m resolution? Aren’t they provided in 10x10m?
But when reducing the AOI, I receive results in 10x10m. Here is an example for 10x10m overlapping the screenshot from above.
