T h e effect of variable tree canopy cover, shadows, and topography on Thematic Mapper (TM) data was examined for blue oak (Quercus douglasii) woodland and wooded grassland on rugged terrain in central California. Thematic Mapper data were analyzed from September 1986 (trees in leaf, grass understory senescent) and December 1984 (trees leafless, grasses emerging. Tree cover measured in 84 60 m ...

Spectral mixture analysis (SMA) is a very important task for hyper-spectral image analysis, in general, and subpixel data extraction, in particular. In this paper we present a new methodology for spectral unmixing, where a vector of fractions, corresponding to a set of endmembers (EMs), is estimated for each pixel in the image. The process first provides an initial estimate of the fraction vect...

To generate a high-spatial-resolution hyperspectral (HHS) image from multispectral (HMS) image, both spatial information and spectral should be considered simultaneously if we want to build more accurate mapping HMS HHS. this end, jointed super-resolution method is proposed in letter using an end-to-end learning strategy for each subspace with the cluster-based multibranch backpropagation neura...

Intertidal macroalgal habitats are major components of temperate coastal ecosystems. Their distribution was studied using field sampling and hyperspectral remote mapping on a rocky shore Porspoder (western Brittany, France). Covers both dominating macroalgae the sessile fauna were characterized in situ at low tide 24 spots, according to four bathymetric levels. A zone ca. 17,000 m2 drone equipp...

Mapping and tracking invasive alien plant species (IAPS) their invasiveness can be achieved using remote sensing (RS) geographic information systems (GIS). Continuous monitoring RS, GIS modelling are fundamental tools for informing invasion management strategies. Using systematic comparisons, we look at three imagery platforms how accurately they classified within the Vhembe biosphere reserve, ...

Together with geological survey data, satellite imagery provides useful information for mapping. In this context, the aim of study is to map units Saka region, situated in northeast part Morocco based on Landsat Oli-8 and ASTER images. Specifically, aims to: (1) lithological facies volcanic zone, (2) discriminate different minerals using imagery, (3) validate results field observations maps. To...

Humans can fairly easily identify roads in remote sensing images, but this has turned out to be a difficult task for computers. Most previous work in this area has utilized statistical and rule-based techniques, which depended primarily upon spectral information. However, it appears that spectral information alone is insufficient to identify roads in Landsat Thematic Mapper satellite imagery, s...

A reliable land cover (LC) map is essential for planners, as missing proper maps may deviate a project. This study focusing on classification and prediction using three well known classifiers remote sensing data. Maximum Likelihood classifier (MLC), Spectral Angle Mapper (SAM), Support Vector Machines (SVMs) algorithms are used the representatives parametric, non-parametric subpixel capable met...

Mafic–ultramafics complexes are crucial for their tectonic implication, upper mantle condition, and hosting industrial minerals in a region. This study aims to highlight characterize the mafic–ultramafic rocks of Logar Ophiolite Complex using integration geospatial technology field data. The spatial distribution ophiolitic complex was examined this mineralogical indices (MI), band ratio (BR), s...
