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...

The suitability of optical IKONOS satellite data (multispectral and panchromatic) for the estimation of forest structural attributes – for example, stems per hectare (SPHA), diameter at breast height (DBH), mean tree height (MTH), basal area (BA) and volume in plantation forest environments – was assessed in this study. The relationships of these forest structural attributes to statistical imag...

This paper describes development of feature extraction algorithms using spectral and spatial attributes for detecting specific urban features. Spectral and spatial heterogeneity of urban environment present challenges to their accurate detection and classification from remotely sensed data. Methods include segmenting Ikonos data, computing attributes for creating image objects, and classifying ...
