Mapping wetland areas on forested landsacpes using Radarasat-2 and Landsat-5 TM data por Martin, Jennifer

“…Fourteen Radarsat-2 Fine Quad (FQ) SAR images were acquired from October 2010 to November 2011 at different incidence angles but with the same orbit-descending pass (west-looking direction). The images were paired according to the beam mode (FQ4 and FQ22/27), leaf presence (off and on) and moisture (wet/dry) conditions. …”

Pastoral herd management,drought coping strategies, and cattle mobility in southern Kenya por Butt, B., Shortridge, A., Winkler Prins, A.M.G.A.

“…Modified Global Positioning System (GPS) collars were placed on cattle from ten Maasai households that recorded three parameters of mobility for hundreds of grazing orbits from August 2005 to August 2006. Data were grouped by two constraints—seasonality and herd size—and tested against the two types of enclosure locations (temporary camps and permanent settlements). …”

Application of a flood inundation model to analyze the potential impacts of a flood control plan in Mundeni Aru River Basin, Sri Lanka por Yoshimoto, Shuhei, Amarnath, Giriraj

“…Satellite images have commonly been used for flood mapping, but there are limitations such as unavailability due to satellite’s orbital period or cloud cover. Additionally, it would also be beneficial for policy makers to figure out the impact of water management measures such as water storage options on flood mitigation and irrigation water strengthening. …”
