Urban land cover mapping using object/pixel-based data fusion and ikonos images
Remote Sensing Data Fusion Object/Pixel-Based Classification
2015/8/21
The use of high resolution IKONOS imagery should make it possible to extract urban features like buildings and roads more easily
than conventional satellite image data. This work examines the synerge...

Amazonia Fraction Images Landsat TM
2015/8/21
This paper presents a comparison between L-band HH JERS-1 SAR and Landsat TM data for land cover assessment in an Amazonian
test site. For this, a study area located in the south of Rondo坣ia State, w...
Unmixing-based Landsat and MERIS image fusion for land cover mapping over the Netherlands
Linear mixing model spatial unmixing Landsa
2015/8/21
Anthropogenic land use activities are significantly contributing to the ecological degradation of the Earth system. Therefore, having

Regional scale land use/land cover classification using temporal series of modis data
remote sensing multitemporal image processing land use classification
2015/8/21
This paper describes a methodology for systematic land use/land cover classification on a regional scale, with emphasis on a low cost
and highly automatized approach. This methodology is based on mul...
Analysis of spatial variations of abuja land use and land cover from image classification algorithms
Land Use, Land Cover, Image Classification Algorithms
2015/8/20
What image classification does is to assign pixel to a particular land cover and land use type that has the most similar spectral signature.
However, there are possibilities that different methods or...
The effect of stratified topographic correction on land cover classification in tropical mountainous regions
Forestry Land Cover Classification
2015/8/20
Topographic correction is an important data preprocessing step when land cover classification and quantitative analysis of
multispectral data are carried out in mountainous regions. Solar illuminatio...
Land cover classification in ukrainian carpathians using the meris terrestrial chlorophyl index and red edge position from envisat meris data
MERIS Terrestrial Chlorophyll Index Red Edge Position Ecosystems monitoring
2015/8/20
This paper describes the results of a preliminary study towards the use of MERIS data for land cover classification in the Ukrainian
Carpathians. The work is carried out in the frames of BEAR initiat...
