Coastal areas are vulnerable to change because, in this region, many human activities and natural influences change. These can result changes the existing coastline. Moreover, city of Surabaya has a reasonably long This study calculated speed shoreline using remote sensing technology SPOT 6 7 high- resolution satellite imagery from 2015 2019. Calculation is assisted by application Digital Shore...

The continuous monitoring of a shore plays an essential role in designing strategies for protection against erosion. To avoid the effect clouds and sunlight, satellite-based imagery with synthetic aperture radar is used to provide required data. In contrast standard model-driven methods, we present deep-learning-based approach detect coastlines such We split process into data preprocessing, mod...

Land use patterns are fragile and sophisticated in Taiwan. In order to rapidly derive detail information of land use/land cover, it is necessary to employ remote sensing techniques because of its broad area coverage and fast data acquirement. The purposes of this research are to use high-resolution satellite images, such as IKONOS, to obtain urban land use information, and to apply fuzzy algori...

This paper presents the results of the assessment of the developed techniques for line-based and combined point/line-based eight parameters projective equations. The developed equations were implemented in a general least squares adjustment technique where both lines and/or points can be used for the rectification of both aerial and satellite images. Several experiments were performed using the...

Vision is the most important resource of information for human beings which contain several activities. Amongst these activities, object recognition and classification are widely used. Although, images are representation of vision which can be interpreted by machines, some images often do not exhibit regions of uniform intensity, but these images may contain variation of intensities which form ...

Images from the GOES 8 satellite were used along with auxiliary information such as snow cover to produce an hourly solar radiation database on a 0.1° grid for the Pacific Northwest from 1998 through 2002[1]. Both global and beam irradiance values were derived from the satellite images and diffuse values were calculated from the beam and global values. Data from the University of Oregon Solar R...
