This research proposed an approach for automatic extraction of buildings from digital aerial imagery and LiDAR data. The building patches are detected from the original image bands, normalized Digital Surface Model (nDSM) and some ancillary data. Support Vector Machines (SVMs) and artificial neural network (ANNs) classifiers have been applied indiv...

Integration of ground and space geodetic datasets to monitor the surface deformation has become an effective and important way to take the advantages of both techniques in such studies. Global Positioning System (GPS) calculates the crustal movement in 3 D space at the receiver location. On the other hand, Differential Synthetic Aperture Radar (DIn...

Roads are the mainstay of any new development and it was requirement to be located occur seamless and optimal connection. Determining the route location is one of the biggest planning problems facing us at present while constructing new one. It was involved to evaluate of different agents in order to obtain optimal and least cost place. The goal of...

The RFM has been considered as a generic sensor model. Compared to the widely used polynomial models, RFM is essentially a more generic and expressive form. Utilizing the RFM to replace physical sensor models in photogrammetric mapping is becoming a standard way for economical and fast mapping from high-resolution imagery. This model uses the Ratio...

Land use map considered as one of the most essential problems for planning and managing schemes to come across the increase in demands for basic human requirements and prosperity of the ever increasing population. Remote sensing is an important tool for the creation of land use maps by the use of image classification techniques. GIS is a tool that...

Digital Elevation Models (DEMs) are used in many applications in the context of earth sciences such as in topographic mapping, environmental modeling, rainfall-runoff studies, landslide hazard zonation, seismic source modeling, etc. Accurate DEM can be derived from SAR (Synthetic Aperture Radar) acquisitions by InSAR (Interferometric synthetic aper...

region for Egypt at both the national and strategic levels. Roads network is necessary for urban planning. Also base maps forms a base for determination of the soil suitability for reclamation, urban development and selection of the suitable type of development and investment that could be made in the area. An accurate and up-to-date road network d...

The spread of urban develop ment in the west delta and studying the factors of attraction and expulsion in the new cit ies and reclamation of desert land in Egypt becomes a hot issue nowadays. That is to solve the crisis of greater Cairo and central delta; this is in order to re-planning some new cities such as Sadat city that has been used as a st...

Sinai Peninsula is considered a very important region for Egypt at both the national and strategic levels. One of the important problems facing the researches of Sinai development there is not available detailed information about population and their distribution, so this is still a research topic. Sinai population represented approximately 0.6% fr...

Sinai peninsula is considered a very important region for Egypt at both the national and strategic levels. This region needs some development. Roads network will be needed for urban planning. Also base maps forms a base for determination of the soil suitability for reclamation, urban development and selection of the suitable type of development and...

Mapping of urban features (e.g. roads and buildings) from satellite images has gained enormous research interest. Geoeye-1 allows for accurate and reliable extraction and characterization of even more details of the earth surface. Large scale maps could be achieved from both Panchromatic (PAN) Geoeye-1 (0.5 m resolution) and MultiSpectral (MS) Geoe...

Egypt has launched its first Earth remote sensing satellite EgyptSat-1 in 2007. A series of evaluations of the usefulness and limitations of EgyptSat-1 images for different applications are required. This research is concerned with the investigation of the geometric and cartographic potential of EgyptSat-1 image in order to know to what scale Egypt...

Buildings are one of the most important geospatial features for spatial analysis and mapping. Building extraction has been an active research topic in computer vision as well as digital photogrammetry in recent years. Building detection is the process of obtaining the approximate position and shape of a building, while building extraction can be de...

Obsolete maps creates so many problems to engineers, planners and other professionals who need to develop their work based on updated records. An extensive and time-consuming field revision would be required to update such obsolete maps. On the other hand the conventional methods of map revision with aerial photographs are so costly and highly time...
