It is still a great challenging task to efficiently produce planetary mapping products from orbital remote sensing images. There are many disadvantages in photogrammetric processing of planetary stere...
In recent years, extensive research has been conducted to automatically generate high-accuracy and high-precision road orthophotos using images and laser point cloud data acquired from a mobile mappin...
The National Mapping Agencies (NMA) of the German federal states derive nationwide digital orthophotos with a ground resolution of 10 to 20 cm by aerial surveys at regular cycles of two or three years...
The paper gives an overview on the problems occurring during commercial digital orthophoto (DOP) production. There is a wide variety in requirements on orthophotos. It is no problem to produce good or...
The Sweden based GAF subsidiary Observation, Mapping and Monitoring AB (OM&M) has produced ortho-images based on IRS data on a routine basis since May 1997.
The production system of middle-scaled topographic maps of the National Land Survey of Finland was re-engineered in 1992-1993 when a new Topographic Data System was introduced. After that data compila...
Dubai Municipality is actively introducing digital orthophotos for solving actual planning needs. Past experience revealed that already available map products are very soon outdated due to a booming e...
Since the eighties, there has been a significant evolution of photogrammetric systems for the production of digital orthophotos. All the various procedures for the generation of orthophotos (for examp...
For the time being usual orthophotos do not place general 3D objects (buildings, bridges, etc) on their geometrically correct positions because conventional algorithms are based on 2.5D digital terrai...
Obtaining up-to-date spatial information about slum settlements is of great importance for decision making related to slum and housing policy. The availability of Very High Resolution (VHR) satellit...
Photogrammetric softwares , functions and applications were tremendously effected by developments of image proccessing technologies in past decades. One of the applications of photogrammetric software...
Nowadays orthophotos from satellite and aerial imagery are very requested products, considering their low cost motivated by the highly automated production chain. The generation of orthophotos require...
The development level of the society and structural characteristics can be seen in urban structure and urbanization. Administration try to keep social justice and welfare by urban, regional and nati...
The digital orthophoto is a valuable tool for representing an object on orthogonal projection at a known scale, due to the relation between its relatively low production cost and the photographic det...
The generation of digital Orthophotos now days can be done with aerial, but also very high resolution space imagery. For a real competition the geometric and radiometric quality has to be on the same...
