Characterization of suburban areas for land use planning using landscape ecological indicators derived from IKONOS-2 multispectral imagery
Very high resolution satellite images are used to derive the spatial distributions of landscape ecological metrics within suburban areas. These indicators are weighted mean patch size and lacunarity computed from thresholded normalized difference vegetation index obtained from multispectral IKONOS-2 imagery. Spatial distributions of the metrics are derived for an extensive suburban area on the ...
متن کاملUse of Multispectral Ikonos Imagery for Discriminating between Conventional and Conservation Agricultural Tillage Practices
There is a global concern about the increase in atmospheric concentrations of greenhouse gases. One method being discussed to encourage greenhouse gas mitigation efforts is based on a trading system whereby carbon emitters can buy effective mitigation efforts from farmers implementing conservation tillage practices. These practices sequester carbon from the atmosphere, and such a trading system...
متن کاملCombining Lidar Elevation Data and IKONOS Multispectral Imagery for Coastal Classification Mapping
This article studies the effect of airborne lidar (surface) elevation data on the classification of multispectral IKONOS images over a coastal area. The lidar data and IKONOS images are treated as independent multiple bands to conduct the classification. To do so, the lidar elevation data is first resampled to the same ground spacing interval and stretched to the same radiometric range as the I...
متن کاملObject-oriented classification and Ikonos multispectral imagery for mapping vegetation communities in urban areas
The management of vegetated areas by urban planners relies on detailed and updated knowledge of their nature and distribution. Manual photo-interpretation of aerial photographs is efficient, but is time consuming. Image segmentation and object-oriented classifications provide a tool to automatically delineate and label vegetation units. Object-oriented techniques were tested with a very high-re...
متن کاملPractical Aspects of Ikonos Imagery for Mapping
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...
