Framed by Sunset World Resorts & Vacation Experiences 25th anniversary celebration, last Sunday, May 14th Hacienda Tres Ríos Triathlon hosted its seventh annual Hacienda Tres Rios Triathlon. More than 500 triathletes participated beginning their day by the beach early in the morning to start the competition, which was divided in 12 categories in the sprint, children’s and relay classifications. Sprint classification started the competition at 7:00 am with a 750-meter open ocean swim and a counter-current river swim up to Hacienda Tres Rios’ famous cenote el Águila. Later that day, the athletes rode 20 km on the Playa del Carmen - Cancún highway and finished with 5 km running in the 326-acre Tres Ríos Natural Park. Victoria Juanicotena from Cancún, and Rodrigo Camarillo from Cozumel won the competition. Juanicotena finished in 1 hour 12 minutes and 41 seconds; Camarillo finished in 1 hour 4 minutes and 10 seconds. During the award ceremony special recognition was given to Marcos Velázquez, a blind triathlete who participated in this year’s event. “Hacienda Tres Ríos Triathlon keeps attracting more athletes from México and the rest of the world, with events like this one we are positioning our destinations at the forefront in the sports tourism sector,” said Annie Arroyo, Director of Brand and Communication at Sunset World Resorts & Vacation Experiences. “We applaud all athletes and thank our sponsors for helping make this event possible including Grupo Regio, Powerade, Agua Cristal, Innovasport, Costamed, Title Boxing, Aguakán, Rojo Violeta, Victoria’s School, and volunteers from Calica and Gestalt,” she added.

Personalization is very important feature of any Location Base Service (LBS) as it improves its usability. The paper focuses a problem of development of personalized LBSs. In the paper, a novel approach based on ontology engineering is proposed to provide an intelligent (semantics-based) solution to personalization problem of LBS. The approach uses geospatial ontologies, ontology-based user profiling and multilingual output for personalization of services. The provided ontology-driven development framework for personalized LBS is evaluated by implementing the personalized reverse geo-coding service use case. © 2011 The authors and IOS Press.

In this study, an extensive flood in Estonia during spring 2010 was mapped with TerraSAR-X data acquired over both open and forested areas. This was the first time when a large scale flooding area was mapped in Estonia by means of spaceborne remote sensing. This was also the first time when X-band SAR images were successfully used for flood mapping under the forest canopy in the temperate forest zone. The tree height in the study region was 15-25 meters on average, and main tree species were birch (leaf-off condition), pine and spruce. The results were compared with ALOS PALSAR and Envisat ASAR images of the same flooding event. In the study area, TerraSAR-X provided on average 3.2 dB higher backscatter over mixed forest flooded areas compared to non-flooded areas. In deciduous and coniferous forests the difference in average backscatter between flooded and non-flooded forests was even greater, 6.2 dB and 4.0 dB, respectively. A supervised classification algorithm was developed to produce high resolution maps of the flooded area from the TerraSAR-X images to demonstrate the flood mapping capability at X-band. Our results show, that spaceborne X-band SAR data, which currently has the highest resolution among the SAR instruments in space, can be used to map floods under forest canopy in temperate zone despite its short wavelength and high attenuation. © 2008-2012 IEEE.
