An effective pansharpening method for WorldView-2 satellite images
2015 International Conference on Estimation, Detection and Information Fusion (ICEDIF), 2015Pansharpening has been an important tool in remote sensing applications, which transforms a set of low-spatial-resolution multispectral images to high-spatial-resolution images by fusing a co-registered fine-spatial-resolution panchromatic image. The new style very high-resolution WorldView-2 satellite images have posed challenges to the image fusion ...

Pansharpening in coastal ecosystems using Worldview-2 imagery
SPIE Proceedings, 2016Both climate change and anthropogenic pressure impacts are producing a declining in ecosystem natural resources. In this work, a vulnerable coastal ecosystem, Maspalomas Natural Reserve (Canary Islands, Spain), is analyzed. The development of advanced image processing techniques, applied to new satellites with very high resolution sensors (VHR), are ...

Using WorldView-2 to determine bottom-type and bathymetry
SPIE Proceedings, 2011Observations taken from DigitalGlobe's WorldView-2 (WV-2) sensor were analyzed for bottom-type and bathymetry for data taken at Guam and Tinian in late February and early March of 2010. Classification of bottom type was done using supervised and unsupervised classification techniques. All eight of the multispectral bands were used.

Determination of tree species using Worldview-2 data
2012 IEEE 8th International Colloquium on Signal Processing and its Applications, 2012Determining tree species has involved a lot of studies in the past decades. This is because of the availability of certain tree species to produce a high market value type of wood or that it can be use for meditational purposes. In the old days, conventional method of survey needs to be conducted to identify tree species.

Assessment of pan-sharpening methods applied to WorldView-2 image fusion
2015 IEEE International Geoscience and Remote Sensing Symposium (IGARSS), 2015Various multispectral (MS) and panchromatic (PAN) fusion (or pan-sharpening) algorithms were developed to produce an enhanced MS image of high spatial resolution. Regarding the novelty in both the PAN and MS bands of the WV-2 imagery, the objective of this study is to assess the performance of nine state-of-the-art pan-sharpening methods for the WV-2 ...

Evaluation of soil moisture content from ASTER and Worldview 2 imageries
2014 IEEE Geoscience and Remote Sensing Symposium, 2014The traditional approach of soil mapping is time consuming and requires large amount of investments, especially for large scale areas, whereas the reflectance spectrometry for assessing the spectral behavior of soil has been an alternative [13]. This study aims to predict the moisture level in soil and significant wavelengths pointing the moisture ...

The optimal parameter combination for vehicle detection from worldview-2 imagery
2016 International Conference on Logistics, Informatics and Service Sciences (LISS), 2016Vehicle detection and traffic flow parameters extraction from high resolution imagery have been popular research topics in recent years. Object-based image analysis, with the aid of commercial eCognition® software, has become a widely implemented method for vehicle detection and identification.

A comparison of hyperspectral data and worldview-2 images to detect impervious surface
2012 4th Workshop on Hyperspectral Image and Signal Processing (WHISPERS), 2012One of the most important issues in urban area study during these years is loss of land resources due to rapid expansion and development of urban centers and cities therefore impervious surface (IS) is increased. Thus detection and mapping the impervious surface accurately is one of the important tasks in urban remote sensing.

Presentation of the Kauth–Thomas transform for WorldView-2 reflectance data
Remote Sensing Letters, 2014We present the Kauth–Thomas (K-T) transform coefficients for the reflectance data of the WorldView-2 (WV-2) sensor. The K-T transform is a widely used spectral enhancement, which employs a set of eigenvectors that transforms the given spectral space into a defined feature space.

Building height retrieval from WorldView-2 multi-angular images
2015 IEEE International Geoscience and Remote Sensing Symposium (IGARSS), 2015The paper presents a new algorithm for the estimation of the heights of buildings acquired by multiangular multispec-tral/panchromatic acquisitions. The proposed method aims at exploiting the complete multiangular spatial and spectral information provided by the WorldView-2 system with controlled computational complexity of the overall automated system.
