This question is not about visualization so it may not be related to https://community.planet.com/topic/show?tid=159&fid=3
even there are some similarities. My issue is that I am feeding a Keras model where I need to basically use a 0.0 to 1.0 color space. Now for regular RGB images I would simply do a rescaling with /255. For Sentinel2 I’d do /10000 but what is the correct factor for Planet
```
PSScene
Asset types

    ortho_analytic_4b_sr
    ortho_analytic_4b_xml
    ortho_udm2
```
I do not want an individual range per scene but a “standard” rescaling factor. If there are outliers (as with Sentinel2 NIR channel) this would be Ok.
thank you very much for your support.
