In the support of defense agencies and civil authorities TNO runs a research program that strives after automatic generation of terrain databases for a variety of simulation applications. Earlier papers by TNO at the IMAGE conference have reported in-depth on specific projects within this program. Rather than being in-depth on a specific subject, this paper provides a more global update on recent results that were obtained in a number of different projects. The projects have focused on techniques to create geospecific terrain databases from imagery and on techniques that procedurally create geo-typical terrain based on sketch input. The results demonstrate that automatic techniques are available for the creation of terrain databases that are fitforpurpose for most training and part of the mission rehearsal simulation applications.
