I am using QGIS 3.4,3

I want to use Raster Calculator to create NDVIs using Planetscope AnalyticMS_SR.tif

I know that the band order for Planetscope is BGRN When I import the multiband SR into Raster calculator I see the bands numbered 1 to 4

When I look at the multiband SR in Layer Properties/Histogram the bands are numbered and colored indicating that B1 is R, B2 is G, B3 is B and B4 is purple and must be NIR. This is not the order of bands that Planetscope provides

When I look at the SR file in S-A CP Band Set I see a list of bands 1-4, but I cannot find other information about them because Planetscope is not included in the list for quick wavelength settings

How can I be sure that I have Red and NIR bands correctly identified in Raster Calculator to create the NDVI?

  • Can you please run gdalinfo AnalyticMS_SR.tif | grep ^Band and add the bands reported to your question? (Or run just gdalinfo AnalyticMS_SR.tif) – jgrocha Jan 10 at 20:31
  • Ran Processor Toolbox - GDAL - Raster- Misc. - Raster info. – James K Jan 12 at 2:08
  • Your data is BGRN therefore B1 is blue, B2 is green etc in the raster calculator. QGIS is just showing you a default "RGB" composite using the first 3 bands in the wrong order - BGR. ArcGIS does this as well unless you change the default setting. – Luke Jan 14 at 7:50
  • Thank you Luke for the clarification. Why is this not clearly stated in the documentation? – James K Jan 15 at 12:25
