Estimation of Forest Stand Characteristics Using Spectral Histograms Derived from an Ikonos Satellite Image
The aim of this paper was to examine the potential of Ikonos satellite images for estimating boreal forest stand characteristics using frequency distributions of radiometric values. The spectral features selected for use in the estimation were medians, standard deviations, and the parameters of the two-parametric Weibull distribution derived from the standwise spectral histograms of the Ikonos ...
متن کاملTsunami Hazard Assessment in Istanbul Using by High Resolution Satellite Data (ikonos) and Dtm
Historical tsunami events have impacted the Istanbul coasts along the Sea of Marmara. Offshore seismic sources may trigger these tsunamis directly or through coseismic underwater failure. The 1999 zmit Bay tsunami led to more comprehensive analyses of these events which are generally caused by underwater failures close to the target coastline. Waves so generated can arrive at nearby coastlines ...
متن کاملAssessment and Update of Forest Classification Using Multi-parameter Satellite Sar Data for Ne China
The objective of this paper is to improve as well as to assess the performance of mapping forest by ENVISAT ASAR data and update forest map from ERS SAR images. The preliminary results of there test sites show it is very potential to use HH/HV ASAR AP data for forest map update. Tuqiang site have been undergoing dramatic changes during the last several decades due to the regeneration after fore...
متن کاملDevelopment a cartographic index of the vigour of forest stands from Ikonos imagery data
This study develops a cartographic index of forest stands vigour from Ikonos imagery data. The study area located at GOUNAMITZ (New-Brunswick, Canada) consists mainly of fir, tolerant and intolerant hardwoods at mature and overmature stages. Forest inventory plots were set up in the stands; dendrometric measures (height, DBH, annual increment, etc.) were collected and used to estimate reference...
متن کاملIdentification of Urban Characteristic Using Ikonos High Resolution Satellite Image
Land use patterns are fragile and sophisticated in Taiwan. In order to rapidly derive detail information of land use/land cover, it is necessary to employ remote sensing techniques because of its broad area coverage and fast data acquirement. The purposes of this research are to use high-resolution satellite images, such as IKONOS, to obtain urban land use information, and to apply fuzzy algori...
