UPDATING COMPLEX DATABASES - THE NEXT STEP MJ D Brand BA FRICS,:Director and Chief Executive Ordnance Survey of Northern Ireland President OEEPE Commission 1 Special Session, OEEPE KEY WORDS: Orthoimage, Photogrammetry, Updating, Archiving, DEM/DTM, Scanner, GIS ABSTRACT Digital topographic databases are fundamental to management of an ever-increasing range of business functions within a GIS environment. It follows that currency of such databases is critical to effective use of the new technology. The more complex the topographic information involved the greater are the implications to the updating procedures, particularly if in addition to current data, archiving of a historical perspective is a requirement. To date these matters have remained largely unaddressed by software houses generally. The issue increases in importance daily and it is logical that OEEPE should play a leading role in promoting this follow-up activity. Such activity must focus on the use of newer technology, typically digital photogrammetry and monoplotting, and identify means to effectively apply such methodologies to complex topographically structured, multi-featured coded databases. The recently completed OEEPE Commission 1 project "Updating of Complex Digital Topographic Databases" was a major attempt to tease out the principles involved and the difficulties to be overcome in seeking solutions. The paper outlines these and develops on its findings.
