Using JERS-1 and PALSAR radar images provided by JAXA, we built regional and continental scale mosaics of Sahara that allowed to discover major geological features. The unique capability of L-band SAR to map subsurface structures in arid areas revealed several impact craters and paleo-rivers in

Techniques were implemented to extract anthropogenic features in the desert region of North Sinai using data from the firstand second-generation Phased Array type L-band Synthetic Aperture Radar (PALSAR-1 and 2). To obtain a synoptic view over the study area, a mosaic of average, multitemporal (De Grandi) filtered PALSAR-1 σ◦ backscatter of North Sinai was produced. Two subset regions were sele...

Soil salinization is one of the most widespread soil degradation processes on Earth, especially in arid and semi-arid areas. The salinized soil in arid to semi-arid Xinjiang Uyghur Autonomous Region in China accounts for 31% of the area of cultivated land, and thus it is pivotal for the sustainable agricultural development of the area to identify reliable and cost-effective methodologies to mon...

With the launch of ALOS in 2006, JAXA took the initiative to implement the first global-scale systematic acquisition strategy for satellite sensors at fine (2.5m-20m) spatial resolution. Comprising all three sensors on ALOS (PALSAR, PRISM, AVNIR-2), the plan is designed to serve all ALOS user categories and aims at producing spatially and temporally consistent coverages over the planet on a rep...

The Brazilian Amazon has a deficit of 35% of coverage regarding topographic mapping at semi-detailed (1:100,000) scale. This paper presents an alternative to overcome this scenario using a combination of planialtimetric information from two orbital SAR (Synthetic Aperture Radar) missions. The altimetry was acquired from Shuttle Radar Topography Mission (SRTM), while the planimetry was provided ...

Remote sensing data from multi-source optical and SAR (Synthetic Aperture Radar) sensors have been widely utilized to detect forest dynamics under a variety of conditions. Due to different temporal coverage, spatial resolution, and spectral characteristics, these sensors usually perform differently from one another. To conduct statistical modeling accuracies evaluation and comparison among seve...
