I have a series of satellite images and am not sure which satellite took them. I know there are 8 bands but not which band relates to which spectral color. Here is the metadata of one image :

GDAL provider
GTiff

  • how about the metadata ? did you take a look already ? – Uje Indo Mar 28 '16 at 4:48
  • metadate from (qgis) layer properties was the first place i went. but i could not find which layer relates to which band – kwai Mar 28 '16 at 6:26

Looks like DigitalGlobe Worldview-2.

The bands are:

1. Coastal: 400-450 nm
2. Blue: 450-510 nm
3. Green: 510-580 nm
4. Yellow: 585-625 nm
5. Red: 630-690 nm
6. Red Edge: 705-745 nm
7. Near Infrared 1: 770-895 nm
8. Near Infrared 2: 860-1040 nm

To calculate NDVI, use 5 & 7.

  • exactly what i was looking for. where in the data did you find it? – kwai Mar 28 '16 at 6:49
  • @kwai I use DG WV-2 regularly. The no. of bands, pixel size, naming convention and copyright statement is very familiar. Look in the image directory or parent directory for full metadata – user2856 Mar 29 '16 at 8:40
