Specific points to xarray

[wep69]

Dear Aaron Zuzpan

Thank you very much for this wonderful package.
I have in my assets a shp with 64 points, also locally as geojson. I tried following your instruction here , #28, to download sentinel-2 bands to xarray of those specifics 64 points. But, the total points depends of scale and region, being differents in number and localization of those 64.
There is any way to download those specific points to xarray?.

Thank in advance.

Hi @wep69, the instructions in #28 would give you a 2D image array over a region, but it sounds like you want 1D values at each of the 64 points?

If so, you could follow #28, use your points as the region and set the scale to 10 or 20. That will give you a 2D array that covers all your points. Then follow this to extract a 1D time series at each point.

If you don't need xarray functionality and just want an array of values, you could try some non-wxee solutions. If you have just one image for each point, you could try using geemap with this tutorial. If you have a time series of images at each point, you could try this tutorial.

Thank you for your exhaustive answer. The first alternative is a satisfactory solution for my needings.
