UNESCO - Bilko• What:

– It is– It can do– It cannot do– It comes with

• How do you get it?• Potential Uses



What is it?– First developed in 1987

• 4 Guiding Principles– Run on low cost computers– Supported by lessons and image data– Software, lessons, and example data will be free– Students, teachers and users encouraged to enhance

Bilko

– Hosted by UK’s National Oceanography Center.

• Supported by United Nations Educational Scientific and Cultural Organization (UNESCO)



What Can it Do?• Classification

– Supervised– Unsupervised

• PCA• Georectify

– Ground Control Points• Masks • Filters• Transects• Histograms• Scatter-plots• Hovmoller diagrams• Animations

• Supports– GeoTIFF– IMG– HDF– Binary

• BSQ, BIL, BIP– GIF, PCX, BMP– USGS Mapgen

• Numerical formats– 8 bit– 16 bit (signed/unsigned)– 32 bit integer

(signed/unsigned)– 32 bit floating point

Image Classification

•Unsupervised•Supervised



What it Cannot Do• Bilko does not have a Digital Elevation

Module– Geometric correction of land data can be

inaccurate• Bilko does not support vector data



What does Bilko come with?• Tutorials

– How do use the software.– Common image processing methods.

• Mini – Lessons– Short tutorials for specific advanced image

processing methods.• Lessons

– Applications of remote sensing data.• Modules

– Collections of lessons with a common theme.



How do you get it?• http://www.noc.soton.ac.uk/bilko/index.php• Register with your email, name,

occupation, and country– Use the email address you register with to

access the software/tutorials/updates/ etc…• You won’t receive countless emails from

BILKO

So What?• Learn new or hone old remote sensing

theory, and application skills• Perform in-house imagery analysis• Better understanding of remote sensing

data sets• Save money



Future applications• Connecticut View

– Provide data to users in the state of Connecticut

– Education opportunities for the K-12 environment

• Inspiring Connecticut's future workforce with the skills that are needed and will be needed.
