Fine-scale mapping of vector habitats using very high resolution satellite imagery : a liver fluke case-study [PDF]
, 2014 The visualization of vector occurrence in space and time is an important aspect of studying vector-borne diseases. Detailed maps of possible vector habitats provide valuable information for the prediction of infection risk zones but are currently lacking

Urban feature extraction on simulated WorldView-2 images
Joint Urban Remote Sensing Event 2013, 2013 This work presents a procedure for simulating the eight multispectral bands of the WorldView-2 satellite by means of bands available in the airborne sensor HSS (Hyperspectral Scanner System). Both the original and simulated images were classified using the SAM (Spectral Angle Mapper) algorithm, aiming to discriminate intra-urban targets, namely: French

Pansharpening techniques to detect mass monument damaging in Iraq [PDF]
, 2017 The recent mass destructions of monuments in Iraq cannot be monitored with the terrestrial survey methodologies, for obvious reasons of safety. For the same reasons, it’s not advisable the use of classical aerial photogrammetry, so it was obvious to ...

Segmentation of High Resolution Worldview-2 Satellite Images
International Journal of Advanced Remote Sensing and GIS, 2019 This paper presents the segmentation technique used to segment the Worldview-2 high resolution satellite multispectral (MS) images. First the spectral features like Simple Ratio (SR), Normalized Difference Vegetation Index (NDVI), Soil Adjusted Vegetation Index (SAVI) and Modified Soil Adjusted Vegetation Index (MSAVI) are considered to extract the ...
