This study is part of the “Milan Cathedral Survey project”. It is a three years long research project with the aim of surveying the entire cathedral in 3D with different techniques (mainly photogramme...
With the development of digital city, digital applications are more and more widespread, while the urban buildings are more complex. Therefore, establishing an effective data model is the key to expre...
At present, in the inspection and acceptance of high spatial resolution remotly sensed orthophoto image, the horizontal accuracy detection is testing and evaluating the accuracy of images, which mostl...
Various kinds of urban applications require true orthophotos. True orthophoto generation requires a DSM (Digital Surface Model) to project the photo orthogonally and minimize geometric distortion due ...
This study used in-situ GPS data to validate the accuracy of horizontal coordinates and orientation of linear features of orthophoto and line map for Bahir Dar city. GPS data is processed using GAMIT/...
It is important nowadays to underline some relevant topics concerning the effective contribution of 3D high detailed products derived from innovation and integration of Geomatics technologies, allowin...
When creating set of orthophoto maps from mosaic compositions, using airborne systems, such as popular drones, we need to publish results of the work to users. Several steps need to be performed in or...
Digital orthophoto maps have great advantages of high precision, plentiful information, fine intuition and visualization and convenient acquisition, as one of the most important part of national spati...
The Orthophoto CR is produced in co-operation with the Land Survey Office and the Military Geographical and Hydrometeorological Office. The product serves to ensure a defence of the state, integrated ...
Orthophoto imagery is a valuable layer in a GIS because it provides a generic, inexpensive, and accurate base map.However, in cities with tall buildings it is difficult to create a seamless database o...
Automatic Digital Aerial Triangulation has been implemented at the Institute of Geodesy and Cartography in 1997 on the ImageStation 6487 INTERGRAPH. Several blocks of B/W aerial photographs in the sca...
The main aim of the research described in the paper was analyse the accuracy of photointerpretation of impervious surface using IKONOS images and its influence on the imperviousness factor determinati...
Digital orthophotography has been a powerful tool for large scale geometric documentation of monuments for over a decade. However, several factors prevent the smooth implementation of commercially av...
Orthophoto is an image which is being corrected geometrically so each object has to be situated on the corrected place consequently. Choosing the best DEM structure with respect to the area topographi...
