How to extract wavelength value and reflectance values from each point in image

Hi Aman,

Thanks for posting this question in the Planet community. The wavelengths for a specific Planet image will depend on the instrument (PS2, PS2.SD, and PSB.SD). You can find the wavelengths for Planet instruments in the link: https://developers.planet.com/docs/apis/data/sensors/#band-order-and-sensor-frequency

You can extract reflectance values from the surface reflectance product (analytic_sr). More information available at https://developers.planet.com/docs/data/planetscope/#surface-reflectance-product-processing 

By using the Identify feature tool in QGIS, you will be able to inspect the pixel values of the image.

If we can be of any further assistance, please let us know.

Thank you!

Ricardo
