Pan-sharpening/processing data from RedEdge-P sensor in Agisoft Metashape

There are only a few extra steps when processing RedEdge-P data compared to processing RedEdge-MX or Altum data. For the general guide, view our guide here: Process MicaSense sensor data in Agisoft Metashape.

Before aligning the data, be sure to set the primary channel to be the Panchro channel under the Tools>Set Primary Channel menu:

After changing this setting, you can continue to process as usual. 

 

At the end of your usual processing workflow, you can use the Raster Calculator (Tools>Set Raster Transform to create a pan-sharpened version of your dataset. If you want reflectance values, you can divide all of the formulas by 32768, as seen here:

If you would refer digital number values, you can use the formulas without the extra division:

The formulas above can be copy pasted from here:

 

#divide by 32768 to get the reflectance values for each band instead of digital numbers
B1 * (B3 / (0.2 * B1 + 0.2 * B2 + 0.2 * B4 + 0.2 * B5 + 0.2 * B6))/32768 B2 * (B3 / (0.2 * B1 + 0.2 * B2 + 0.2 * B4 + 0.2 * B5 + 0.2 * B6))/32768 B4 * (B3 / (0.2 * B1 + 0.2 * B2 + 0.2 * B4 + 0.2 * B5 + 0.2 * B6))/32768 B5 * (B3 / (0.2 * B1 + 0.2 * B2 + 0.2 * B4 + 0.2 * B5 + 0.2 * B6))/32768 B6 * (B3 / (0.2 * B1 + 0.2 * B2 + 0.2 * B4 + 0.2 * B5 + 0.2 * B6))/32768 #0.2 being default weight

 

Finally, when you export the orthomosaic, you want to export this raster transform data by choosing "Index value" under the "Raster transform" option. If you don't want to create a pan-sharpened dataset, you can choose "None" for "Raster transform".

When you are doing calculations (whether in GIS or within Metashape itself), the band order will now be the same as with a RedEdge or Altum:

 

Band 1  Blue
Band 2 Green
Band 3 Red
Band 4 Red edge
Band 5 NIR

If you want to create an RGB composite, you would use bands 3/2/1,  as you would use for a RedEdge-MX or Altum sensor. Likewise, NDVI would be:

(Band 5 - Band 3)/(Band 5 + Band 3)
