Digital surface model generation from CORONA satellite images

ISPRS Journal of Photogrammetry and Remote Sensing, 2002
Abstract Digital surface models (DSMs) are used for various analyses in environmental science, e.g. for erosion and water studies. Aerial photos and maps, which are necessary for the extraction of DSMs, often do not exist due to financial or political reasons.

Robust detection of buildings in digital surface models

Object recognition supported by user interaction for service robots, 2003
There is growing interest in the automatic interpretation of range data acquired by airborne laser scanners. Huge volumes of data involved in land use analysis and building reconstruction applications necessitate a preliminary step to focus attention on interesting areas.

Digital Model of Switching Element Contact Surface

IEEE Transactions on Components, Hybrids, and Manufacturing Technology, 1979
Real contacts adhere to one another only in separate elements of surface, creating so-called contact microfields. This is caused by a lack of perfectly smooth and planar contact elements. Irregularities of contact surfaces cause, in the initial phase of closing contacts, only small surfaces of contact and, moreover, not in many points.

Cosmo-Skymed for digital surface models

2012
New, high-resolution space born sensors offer the possibility of near-real-time 3D Earth surface mapping. Acquiring and processing data rapidly and at low cost as well as being insusceptible to logistical problems or adverse weather conditions they offer great potential monitoring and managing natural disasters and emergencies.

Calculating landscape surface area from digital elevation models

Wildlife Society Bulletin, 2004
There are many reasons to want to know the true surface area of the landscape, especially in landscape analysis and studies of wildlife habitat. Surface area provides a better esti- mate of the land area available to an animal than planimetric area, and the ratio of this surface area to planimetric area provides a useful measure of topographic ...
