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 determination. Two kinds of IKONOS image were chosen to tests: panchromatic and colour pansharp. Airborne ortopho (pixel size of 0.2m) was applied as a reference. Six operators, digitised three times, two kin...

Accompanying the successful deployments of the IKONOS and QuickBird high-resolution satellite imagery (HRSI) systems have been a number of investigations into the utilisation of HRSI for the extraction of precise 3D metric information. Among the promising ‘alternative’ sensor orientation models investigated has been an approach based on affine projection. This model has previously been reported...

The increasing number of sensor types for terrestrial remote sensing has necessitated supplementary efforts to evaluate and standardize data from the different available sensors. In this study, we assess the potential use of IKONOS, ETM+, and SPOT HRVIR sensors for leaf area index (LAI) estimation in forest stands. In situ measurements of LAI in 28 coniferous and deciduous stands are compared t...

This manuscript characterizes several bands of multi-spectral images obtained with different radiometric and spatial resolution by IKONOS-2 and LANDSAT-7 satellites by multifractal analysis. Three of the studied bands were in the visible wavelength spectrum (red, green and blue), while the fourth one was in the near-infrared region. IKONOS-2 images were taken with a radiometric resolution of 11...

High-resolution commercial imaging satellite such as IKONOS provides an important new data sources for urban mapping and geographic information systems (GIS) applications. This paper presents a fuzzy mathematical morphology method for automated extraction of urban road networks from IKONOS imagery. In this proposed method, the road networks in a complex urban scene are firstly modeled, followed...

The latest generation of high-resolution commercial imaging satellites, such as IKONOS and QuickBird, has opened a new era of earth observation and digital mapping. This paper presents the geometric modeling principles and photogrammetric processing methods involved in high-precision mapping using stereo IKONOS and QuickBird images. First, the imaging geometry and systematic errors in the Ratio...

The Department of Construction in Kochi prefecture, Japan established and shared a bridge database without accuracy information. When the data overlay with a commonly used GIS data, some errors appeared. To adjust the accuracy of the bridge database, the intersections of roads and rivers of the National Land Digital Information (NLDI) of Japan were used in the accuracy adjustment, and 64% of br...

Few studies have evaluated the precision of IKONOS stereo data for measuring forest canopy height. The high cost of airborne light detection and ranging (LiDAR) data collection for large area studies and the present lack of a spaceborne instrument lead to the need to explore other low cost options. The US Government currently has access to a large archive of commercial high-resolution imagery, ...

IKONOS imagery has been used in many commercial, government, and research applications ranging from environment monitoring, to coastal change detection, and to national security. The high costs of IKONOS high end products ~Pro and Precision products! make it extremely attractive to find practical methods that use lower-cost IKONOS Geo products to produce highly accurate mapping products. This p...

Five individual projects characterized the spatial performance of the IKONOS commercial imaging sensor. The result was determination of the spatial image quality of IKONOS data products in terms of the National Imagery Interpretability Rating Scale (NIIRS), the system Modulation Transfer Function (MTF), the system stability over its first year of operation, the characteristics of the Space Imag...
