I am a complete beginner in javascript.
I want to create a custom evalscript on sentinelhub that allows me to retrieve via a WMS request with the python API the Sentinel 2 L2A raw bands as well as the CAB, LAI, FAPAR, FCOVER and CCC products. Added to that I try to optimize the processing units.
For that I started from the following links:
- raw bands : "https://github.com/sentinel-hub/custom-scripts/tree/master/sentinel-2/bands"
- CAB : "https://github.com/sentinel-hub/custom-scripts/blob/master/sentinel-2/cab/script.js"
- FAPAR : "https://github.com/sentinel-hub/custom-scripts/blob/master/sentinel-2/fapar/script.js"
- FCOVER : "https://github.com/sentinel-hub/custom-scripts/blob/master/sentinel-2/fcover/script.js"
- LAI : "https://github.com/sentinel-hub/custom-scripts/blob/master/sentinel-2/lai/script.js"
- CCC : "https://github.com/sentinel-hub/custom-scripts/tree/master/sentinel-2/ccc"
- optimization of processing units via sample type : "https://medium.com/sentinel-hub/sampletype-whats-all-the-fuss-about-d7348b4de647"
I have currently used up all my credits/processing units because of the different tests I have done. Also, I haven't found anywhere a way to test the evalscript before testing it in real life.
In addition to that I would like to resample all bands to 10m resolution when this is not the case. I have not yet integrated this into the code below.
Could you tell me if what I did is correct? Thanks in advance.
Here is the code I have written so far
