Bilko is an open source remote sensing software developed in 1987 that can be used to classify, filter, and analyze remote sensing imagery. It supports common file formats like GeoTIFF and comes with tutorials, lessons, and modules. While it cannot perform digital elevation modeling or support vector data, Bilko is freely available online and provides a cost-effective way to introduce users to remote sensing techniques. Potential applications include educational uses in Connecticut to inspire future workforces.
