Maxar decommissioned satellites'

Planet Rapideye had red edge band and could do chlorophyl, but that constellation was retired in 2020

If you get Planetscope 3 m imagery, with 4 bands in a single geotiff.

You will get a file after unzipping with a name like 20191221_002732_1035_3B_AnalyticMS.tif. There are 2 other TIFFs of less value; one is a mask showing the missing area which MICRODEM does not need.
The swath width will be about 26 km, and there may be several 8-10 km subimages along the track.
You must insure that the path containing the file includes the word "Planet" so that MICRODEM can recognize it.
Data Manipulation,
- GDAL is a manual installation.
- Resample, GDAL rasters, GDAL merge if you want to combine multiple files (it is much harder to merge the individual bands; if you want to do that, you and GDAL can do it on your own)
  - Must copy the files you want to merge into a single directory, since they must be picked in a single dialog box
- Resample, GDAL rasters, GDAL band extraction
  - picking the merged file or the single image
  - Verify 4 bands to extract.
  - There will be single files 20191221_002732_1035_3B_AnalyticMS_b1.tif
Open image. Pick any one of the four band images, and the program will associate them to get color imagery or single band grayscales..

Missing data is 255
