Investigation of the Possibility of Forest Type Mapping in Arid and Semi-arid Regions Using Landsat Etm+ Data
Landsat ETM+ data from the National Park of Khabr in Kerman province, dating May 2000, were analyzed to investigate the possibility of forest type mapping in arid and semi-arid regions.Quality evaluation of the image showed any radiometric distortion. Orthorectification was implemented to reduce relief displacement. The RMS error obtained was less than half a pixel. The ground truth map allocat...
متن کاملIntegration of Lidar, Landsat Etm+ and Forest Inventory Data for Regional Forest Mapping
Recent work has established the utility of waveform sampling lidar for predicting forest structural attributes. Nevertheless, serious obstacles to its wide-spread use still exist. They include the lack of waveform sampling lidar sensors capable of measuring forest canopy structure over large extents, and the practical difficulty of developing widely applicable relationships to predict forest st...
متن کاملmapping spatial variation of disease using classic and bayesian models
abstract disease mapping includes a set of statistical techniques that lead to provide clean maps based on estimation of the incidence, prevalence and mortality rates for the users to be able to estimate the distribution of disease reliably. the main aims of disease mapping are to: describe the spatial variation in disease incidence for the formulation of etiological hypotheses; identify area...
متن کاملForest Type Classification Improvement Using Spatial Predictive Distribution Models
The last experiences showed that spectral data have not sufficient to classify forest types in the mountainous area. In order to clear abilities of spatial models to classify forest types and improve results, an investigation was planned in a case study in the northern forests of Iran by ETM+ data. The spatial models based on aspect, elevation, incorporated aspect-height and homogenous units co...
