ABSTRACT
ABSTRACT: Digital mobile mapping, the methodology that integrates digital imaging with direct georeferencing, has developed rapidly over the past 15 years. What used to be a topic of academic study has become a commercially viable industry. In this paper the major steps in this development are traced and the current state of the art is reviewed. This is done by looking at developments in four specific areas: digital imaging, direct georeferencing, mathematical modeling, filtering and smoothing. The paper concludes with a look into the future and the discussion of some ongoing research at theUniversity ofCalgary, Canada.
