I need information about the product in regarding to PSScene4Band files 

I have a PlanetScope Ortho Scene Product (3B) which includes an AnalyticMS.tif and AnalyticMS_SR.tif files. Based on what I have read so far, the AnalyticMS_SR.tif file is scaled surface reflectance in Digital Number. 

 

So I need again to calculate the reflectance to do analysis or indices calculation on the AnalyticMS_SR.tif.

 

Best Regards

  Hi Muhammed,

  The Surface Reflectance product is not in Digital Number (DN) format. The SR product has been derived from the standard Analytic Product (which is in Top of Atmosphere Radiance values calculated from the Analytic DN product). The SR product is provided as a 16-bit GeoTIFF with reflectance values scaled by 10,000 - no additional calculations are necessary. Let me know if you have any questions regarding this.
