Sea ice floe size distribution and lead properties in the Beaufort and Chukchi Seas are studied in the summer-fall transition 2014 to examine the impact on the sea ice cover from storms and surface waves. Floe size distributions are analyzed from MEDEA, Landsat8, and RADARSAT-2 imagery, with a resolution span of 1–100 m. Landsat8 imagery is also used to identify the orientation and spacing of l...

Monitoring changes on Earth's surface is a difficult task commonly performed using multi-spectral remote sensing. The increasing availability of remote sensing platforms providing data makes multi-source approaches promising, since it can increase temporal revisit rate. However, Digital image processing techniques are needed to integrate the data, since sensors can be quite different in terms o...

Rapid and accurate monitoring of the dynamic change construction land is great significance for strictly controlling arbitrary growth urban protecting agricultural forestry land. In order to master situation use conduct more efficient research on classification, this paper takes Weinan as object uses Landsat8 data under same classification conditions analyze image features various types respect...

Constant temporal and spatial monitoring of the coastline is essential for environmental protection. Waterlines were extracted from multi-source satellite remote sensing images, e.g., Landsat8, MODIS, HY-1C, GF-3 SAR. A semi-automatic methodology threshold segmentation was proposed to detect based on local blocks which suitable both optical microwave images scaling standards across different ty...
