The introduction of satellite digital images with resolution and capabilities compatible with current cartographic systems, in addition to the substantial developments in microcomputer and image-processing oriented equipment, has provided an opportunity to use images from satellite or airborne sensors in the production or updating of digital maps. Problems involved in the integration of raster images within a cartographic system are discussed. These problems, mainly related to geometric alignment between images and maps, and to the raster-vector dichotomy inherent in their respective representations, have been solved with varying success by many commercial systems. Current research aims to reduce or eliminate manual intervention both in the selection of control points for image registration and in the conversion of image structures into cartography-relevant vector elements.
