This paper compares and contrasts predictions of forest height in Sitka spruce (Picea sitchensis) plantations based on mediumresolution Landsat ETM+, high-resolution IKONOS satellite imagery and airborne Light Detection And Ranging (LiDAR) data. The relationship between field-measured height and LiDAR height is linear and highly significant (R 0.98) and so LiDAR height measurements were used to...

Shorelines are recognized as unique features on Earth. They have valuable properties for a diverse user community. At present, photogrammetry is the most popular technique used to capture a shoreline. With improved resolution and accuracy, commercial highresolution satellite imagery is demonstrating a great potential in the photogrammetry application domain. One example is the utilization of IK...

High-resolution ((1 m) satellite imagery and archival World War II era (WW2) aerial photographs are currently available to support high-resolution long-term change measurements at sites across China. A major limitation to these measurements is the spatial accuracy with which this imagery can be orthorectified and co-registered. We orthorectified IKONOS 1 m resolution GEO-format imagery and WW2 ...

DEM (digital elevation model) is available. A study on the use Abstract of stereo Ikonos imagery shows that 5to 10-m contour lines can Recent high-resolution satellite images provide a valuable new be derived with the highest topographic standard (Toutin et al., data source for geospatial information acquisition. This paper 2001). As for geospatial feature extraction for topographic mapaddresse...

The textural and spatial information extracted from very high resolution (VHR) remote sensing imagery provides complementary information for applications in which the spectral information is not sufficient for identification of spectrally similar landscape features. In this study grey-level co-occurrence matrix (GLCM) textures and a local statistical analysis Getis statistic (Gi), computed from...

The problem of differential terrain illumination on satellite imagery has been investigated for at least 20 years and has not been solved satisfactorily. Most past research has been conducted on Landsat imagery where the look angle is nadir. There is no research on topographic correction of IKONOS imagery, which has a higher spatial resolution. The high spatial resolution of IKONOS imagery requ...

An investigation of the application of 1-m Ikonos satellite imagery to 3D point positioning and building reconstruction is reported. The focus of the evaluation of Geo panchromatic imagery has been upon 3D positioning accuracy, radiometric quality and attributes of the image data for building feature extraction. Following an initial review of characteristics of the Ikonos system, the multi-imag...

Mangrove stands of differing species composition are hard to distinguish in conventional, coarse resolution satellite images. The new generation of meter-level satellite imagery provides a unique opportunity to achieve this goal. In this study, an IKONOS Geo bundle image and a QuickBird Standard bundle image were acquired for a study area located at Punta Galeta on the Caribbean coast of Panama...

In order to comprehend detailed forest resources, the use of high spatial resolution data is expected. However, the efficeint forest cover type classification method of high spatial resolution data is not cleared yet. So, this study discussed the potential of the forest cover type classification such as classification of coniferous forest, broadleaved forest, and mixed forest, and tree speices ...
