Abstract 
Digital mapping techniques has reached a stage where raster 
images both from satellites and aeroplanes (photograms) can 
pe utilized in integration with IGS systems. This paper 
Overviews a concept for this integration, first of all with 
a mono photogrammetric solution. Market investigations show 
that this concept covers different large scale requirements. 
Introduction 
Future or already existing graphic databases designed for 
mapping applications need fast updating in fast developing 
areas, i. e. urban areas. 
A digital photogrammetric system integrated with an existing 
geographic database would create the possibility for a fast 
and flexible updating along with editing facilities. 
The system will apply both raster technology (scanned image) 
and vector technology (graphic database).
