Paper Abstract

We describe an integrated system developed to update maps by extracting and identifying roads and other linear features in imagery. Our approach involves registering the map to be updated to the image on a local basis using an affine transformation to eliminate costly preprocessing. Image features are converted to the map coordinate system by inverse transformation. Three strategies for linear structure identification and a method for classifying new roads are discussed.
