10 Jan 2014: A new version of Bilko 3.4 has now been released. It retains the features developed for the EAMNet and ESA LearnEO! projects but fixes the problem with sets found in the earlier version from August 2013. Download from our software page.


Participate in the LearnEO! Lesson Writing Competition
Use your skills with Bilko to develop new lessons in remote sensing. Prizes €5,000, €3,000 and €2,000. Closes end of January 2014. More information and registration

Bilko is a complete system...

...for learning and teaching remote sensing image analysis skills. Current lessons teach the application of remote sensing to oceanography and coastal management, but Bilko routines may be applied to the analysis of any image in an appropriate format, and include a wide range of standard image processing functions.

Supported by UNESCO, Bilko is available to registered users absolutely free!

All you need to download software or lessons is your registered e-mail address.

  • Tutorials deal with how to use the Bilko software, and teach common image processing techniques.
  • Mini-lessons are short tutorials, each dealing with a specific, advanced, image processing topic, that can be completed in about an hour.
  • Lessons generally deal with an application of remote sensing data, and take longer to complete than the mini-lessons - typically 2-3 hours.
  • Modules are collections of lessons with a common theme. This can be an application area such as Coastal Management or different applications of data from a particular satellite.
