I need to calculate the Radiance of Landsat 7 in GEE I read in Data Users Handbook under 5.6.5 how to do this. Here it says, these Values are accessible in the Metadata. Now I am searching the Metadata for Gain and Bias in GEE Link to GEECode. I made a list of all Property names and can not find it. Pls help


Judging your input, you can't. You are using a corrected product:

enter image description here

To calculate radiance of a Landsat Image use an uncorrected product, i.e. USGS Landsat 7 Collection 1 Tier 1 and Real-Time data Raw Scenes. This kind of product has gain and bias.

So change:

LSatTMC = ee.ImageCollection("LANDSAT/LE07/C01/T1_SR")


LSatTMC = ee.ImageCollection("LANDSAT/LE07/C01/T1_RT")

And check metadata information
