We developed an on-demand processing service on the GEO Grid system to generate Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) Digital Elevation Model (DEM) and ortho-rectified images. The latest algorithms of radiometric and atmospheric corrections are also supported on this system (Sekiguchi et al., 2008). We implemented the MODTRAN3.7-based atmospheric correction for ...

Based on its ability to obtain two-dimensional (2D) high-resolution images in all-time and all-weather conditions, spaceborne synthetic aperture radar (SAR) has become an important remote sensing technique the study of such systems entered a period vigorous development. Advanced imaging modes as interferometry, tomography, multi-static imaging, have been demonstrated. However, current in-orbit ...

Geo-specific road databases are sometimes necessary for driving simulation studies. However, manually creating them is very time consuming. One of the reasons is that a real road can have non-uniform cross sections due to irregular shaped road boundaries. Additionally, in the UCF driving simulator system, the road database format requires identification of repeatable cross sections, which is al...

The spatial distribution of population is closely related to land use and land cover (LULC) patterns on both regional and global scales. Population can be redistributed onto geo-referenced square grids according to this relation. In the past decades, various approaches to monitoring LULC using remote sensing and Geographic Information Systems (GIS) have been developed, which makes it possible f...

The metropolitan coastal zone mapping is critical for coastal resource management, coastal environmental protection, and coastal sustainable development and planning. The results of geometric processing of a Shanghai coastal zone from 0.7-m-resolution QuickBird Geo stereo images are presented firstly. The geo-positioning accuracy of ground point determination with vendor-provided rigorous physi...

Geo-features play a key role in object-oriented or feature-based geo-processing system. So the strategy for how-tomanage and how-to-model the geo-features builds the main architecture of the entire system and also supports the efficiency and functionality of the system. Unlike the conventional 2D geo-processing system, geo-features in 3D GIS have lots to be considered to model regarding the eff...

With increased use of various new sensors in mapping such as digital cameras, multi/hyperspectral scanners, radiometers, LIDAR, SAR (IFSAR), etc; multisensor data fusion has become an extremely crucial task of spatial data processing. One of the key aspects of integrating various data types is data geo-referencing. Direct platform orientation provides an efficient tool for geo-referencing at th...

An investigation into the use of alternative sensor orientation models and their applicability for block adjustment of high-resolution satellite imagery is reported. Ikonos Geo imagery has been employed in the investigation, and since the explicit camera model and precise exterior orientation information required to apply conventional collinearity-based models is not provided with Ikonos data, ...

Integrated analysis of ground level images with aerial image data is a new area of computer vision research which is gaining traction due to the availability of high volumes of crowd-sourced and open data that are being collected worldwide. Novel problems such as geo-location from a single or a sequence of ground level images and use of geospatial context in object recognition are active resear...
