Server-side NDVI compositing and multi-AOI ordering for multi-city analyses

Hi Planet Community,

I’m using Planet (via the Python API) to visualize NDVI across multiple cities and exploring how to link it with healthcare data.

My current workflow is:

1. For a single AOI, I submit an order to download NDVI (after bandmath) + UDM2.

2. I compute the composite image locally (e.g., median composite after masking with UDM2).

3. Then I visualize the median NDVI.

Questions:

1. Is there a way to do step (2) on Planet’s side (server-side), and download only one composite image (instead of downloading all scenes and compositing locally)?

2. Is there any way to specify multiple AOIs and download results in a single order (one order for multiple AOIs)?

Thank you so much!
