Tree Crown Mapping in Managed Woodlands (Parklands) of Semi-Arid West Africa Using WorldView-2 Imagery and Geographic Object Based Image Analysis
Detailed information on tree cover structure is critical for research and monitoring programs targeting African woodlands, including agroforestry parklands. High spatial resolution satellite imagery represents a potentially effective alternative to field-based surveys, but requires the development of accurate methods to automate information extraction. This study presents a method for tree crow...
متن کاملPlant Species and Functional Types’ Diversity in Relation to Grazing in Arid and Semi-arid Rangelands, Khabr National Park, Iran
In arid and semi-arid rangelands, grazing as one of the natural or human induced processes has direct and indirect effects on structure and dynamics of plant community and ecosystems. A study was done to analyze the effects of grazing on plant species diversity and Plant Functional Types‘ (PFTs) diversity of arid and semi-arid rangelands. We analyzed plant richness and diversity data from 75 sa...
متن کاملDense Matching for Worldview-3 Multispectral Stereo Images
ABSTRACT: Due to the development of spatial resolution, spectral resolution and multi-image tasking of high-resolution satellite images, the generation of digital surface model (DSM) from high-resolution satellite images becomes an important and practical application. Nowadays, different image matching approaches such as global matching and semi-global matching has been developed to obtain dens...
متن کاملAssessing the Vulnerability of the Land Using the IDI Combination Model in Arid and Semi arid Regions (Khorasan Razavi)
Land vulnerability one of the major global challenges as an objective case of degradation of arid, semi-arid and semi-humid ecosystems caused by natural processes and human activities. However, in order to assess the vulnerability of the land, it is necessary to know exactly the degree of tolerance of ecosystems and the use of indigenous knowledge systems to external conditions.The present stud...
متن کاملMapping savanna tree species using Carnegie Airborne Observatory hyperspectral data resampled to WorldView - 2 multispectral configuration
The advent of hyperspectral remote sensing has provided new opportunities for species mapping. However, the high dimensionality of hyperspectral data limits the application of parametric classifiers for species mapping because of the demand for a large number of training samples. This situation could change with the arrival of new spaceborne multispectral sensors such as WorldView-2 and RapidEy...
