Determining ridge and runnel longshore migration rate using Spot imagery

The sand dunes migration patterns in Mesr Erg region using satellite imagery analysis and wind data

Understanding the situation, behavior and the nature of sand dunes and also their location, transport and deposition are very important. On the other hand, the importance of sand dunes is due to the impacts that they have on water and soil resources, flora and fauna and human infrastructure. This study, looks at the development patterns of sand dunes in Mesr erg region. In the first part, data ...

Landslide Classification Using Lidar-derived Data and Spot Imagery

Using spectral-only information for landslides classification is usually confusing with houses, roads, and other bare lands because these ground features have similar spectral patterns on images. In this study, 3D airborne LiDAR data are integrated with SPOT images for landslide classification for improving classification accuracy. A study area is selected in a subbasin of Shimen Reservoir. SPO...

Determining the sensitivity of SPOT XS imagery for monitoring intertidal and sublittoral vegetation of Otago Harbour

Texture analysis for urban spatial pattern study using SPOT imagery

SPOT panchromatic imagery of Beijing has been studied to capture the unique spatial pattern of the city. Texture analysis, which reveals spatial variations, was adopted to interpret the urban spatial patterns. Statistical and structural texture features were extracted from the SPOT image and evaluated for their capability of detailed mapping of urban structures. Supervised image classifications...

Longshore Sediment Transport Rate Measured by Short-term Impoundment

The total longshore sediment transport rate in the surf zone was measured at a temporary groin installed at Indian Rocks Beach, west central Florida. Approximate mass balance between updrift accumulation and downdrift erosion, which served as an indicator of reliability, was obtained in four of the six runs, which were subjected to further analysis. Magnitudes of three of the four transport rat...
