Band 1 – senses deep blues and violets(coastal/aerosol band)

Bands 2, 3 and 4 – visible blue, green and red Band 5 – Near infrared (plant health) Band 6 and 7 – Short wave infrared (good for

geology) Band 8 – Panchromatic band (greyscale) Band 9 – Cirrus cloud detection Bands 10 and 11 – thermal infrared (ground

temperature)

Registration Information

RegistrationInformation


Note negativevalues insouthern

hemisphere.Subtract from10,000,000 m.

Extract the data from the zip file Import the required bands into an image

processing program for processing (Photoshop,GIMP (free), PixInsight, etc) (see new slide)

Stretch the data in each band from black towhite

Resample the bands so that the images havethe same number of rows and columns

Merge the bands to get colour images and usethe panchromatic band to “pansharpen”

New free program to process Landsat 8 data called“Spectral Transformer for Landsat-8 Imagery”,www.GeoSage.com.

Need to download data from the USGS and un-zip.

This program recognises the bands and locationdata and produces GeoTiffs of pansharpened 3band images.

These GeoTiffs can be read directly into MapInfoor QGIS

Also QGIS is FREE GIS pgm – very good. Check itout at http://www.qgis.org/en/site/.

Un-stretched Data


Stretched Data

Data for bands 2, 3, 4, 6 and 8 stretched Note bands 1 to 7 have a 30 m pixel size Band 8 (Panchromatic Band) has 15 m pixel

size Common Landsat 7 RGB is 321 and this is

equivalent to L8 bands 432 (natural colour) Band 8 is used to sharpen the image to 15 m

resolution. Need to “re-sample” 30 m pixels to 15 m
