Imagery in mapping

For many years remote sensing (RS) techniques have been used to pre-process satellite imagery before being analysed by a Geographic Information System (GIS). Over the last few years there has been a steady trickle of systems emerging that span the two disciplines of RS and GIS. These technologies can now be further enhanced with the addition of an active, intelligent database to provide a truly multi-disciplinary approach to the refinement and subsequent spatial analysis of remotely sensed data. Over the last several years Laser-Scan has been involved in several commercial and research projects for which this multi-disciplinary approach, in particular the use of the active, intelligent database, has yielded significant benefits in terms of both accuracy of results and productivity, when applied to land cover mapping acid monitoring applications.
