I am familiar with the major commercial remote sensing packages (ENVI, IDRISI ERDAS, etc), but I haven't previously had the opportunity to utilize open-source solutions.

I have a several new Landsat-8 images that I would like to mosaic for both simple display and analysis (land cover classification). Is there a go-to open source software for this, or are there many options? A tutorial would also be excellent.

    Mapbox imagery specialist Charlie Loyd wrote a great article for their blog about processing Landsat 8 using only Open Source tools. He added the image to tilemill which you could conceivably use as a basis for mosaicing the scenes together. – Roy Aug 01 '13 at 17:33
  • Good article on getting started - I'm unfamiliar with tilemill, but it looks to be used for creating web maps. Is there something similar that can be used to create maps for classification purposes? – Radar Aug 01 '13 at 20:29

You may consider GRASS GIS which offers a rather complete processing chain for Landsat including radiance correction for Landsat 8. For details, see

http://grasswiki.osgeo.org/wiki/LANDSAT

Examples:

  • Landsat 1-5,7,8 data import
  • Auto-enhance colors, natural color composites
  • Calculate Top-of-Atmosphere Reflectance and band-6 Temperature
  • Haze removal
  • Atmospheric correction
  • Cloud identification
  • image classification
  • time series analysis
  • Export of results

Look at Landsat-util repository

You should also consider using Landsat data from AWS. You can get a good overview of different usages to process Landsat data on this Amazon AWS blog post

For Landsat data downloading, go to LANDSAT-Download repository
