Hello,

I'm a college student and not very proficient in using ArcGis Pro and Planet Imagery.
I would need advice on the Apparent Reflectance tool. I'm working with images from the PlanetScope satellite and I don't know where the problem is, but I don't see the metadata of the images. It's rejecting my data format. So I opened the metadata in a normal browser. To create I need Radiance Gain and Radiance Bias for each band. I'm not sure, but isn't it Radiometric Scale Factor and Reflectance Coefficient in the source current? Next I need the Sun Elevation, so I assume that is the same as the Illumination Elevation Angle? And I also know the Scale Factor and Offset, because it results from the number of bits in the image.
So I tried to use these values to create. But it told me that the Acquisition Date is missing, probably because I don't have the metadata uploaded there. So now I don't know what to do with it, because I have nowhere to write the Acquisition Date.

I will be grateful for any advice.

Thank you, Tereza
