Detection of urban objects in very high resolution (VHR) satellite imagery is challenging due to the similarities in the spectral and textural characteristics of urban land cover classes. Therefore, additional information such as elevation data is required for a proper classification. In this study, instead of LiDAR data, elevation information generated from satellite stereo images is used to a...

The recent launch and operational deployment of the WorldView-2 satellite by DigitalGlobe has remote sensing experts around the world in a state of excitement. Not only does this advanced new satellite offer extremely high resolution imagery with 50cm pixels, but the 8 bands that it collects promise greater insight into classifying and mapping the world in which we live. Besides the visible col...

The Uanium mineralization within the Vempalli dolomites of Cuddapah Super group in Mabbuchintalapalli, , Tummalapalli area falling in the Survey of India Toposheet No. 57 J/7. The Remote Sensing data obtained from IRS P6 LISS III imagery of both the areas is taken as reference for the Interpretation studies. The Remote Sensing data obtained from IRS P6 LISS III imagery of both the areas is take...

Imagery is the basic input element of the photogrammetric map production. For decades, aerial photography has been the dominant option to fulfill the imagery request of the photogrammetry and the other disciplines. Due to the significant development in the field of remote sensing spacecraft and the on-board sensors, space imagery has become a serious alternative to the aerial photography. High-...

Availability of high-resolution imagery, such as IKONOS (from Space Imaging Corp), has opened new possibilities for satellite-based mapping. This paper aims to share the practical experience of authors in using IKONOS imagery for mapping application in a production environment. Authors are involved in an IKONOS based land-cover mapping project jointly undertaken by Intergraph Philippines Corpor...

You can download an installation guide, sample data, and the latest version of TNTmips. Imagery acquired by airborne or satellite sensors provides an important source of information for mapping and monitoring the natural and manmade features ...

A segmentation and hierarchical classification approach applied to QuickBird multispectral satellite data was implemented, with the goal of delineating residential land use polygons and identifying low and high socio-economic status of neighbourhoods within Accra, Ghana. Two types of object-based classification strategies were tested, one based on spatial frequency characteristics of multispect...

19. ABSTRACT (Continue on reverse il necessary and identify by block number) Satellite imagery of the oceans has become an invaluable tool for the oceanographer, adding the breadth of synoptic coverage to the depth of in situ measurements at a few points. But the deluge of oceanographic data expected to come from satellites in the near future will pose severe problems for operational interprete...
