In order to support the communications needs of Earth-observing instruments on the International Space Station (ISS), alternative communications architectures to provide broadband support need to be considered. In this paper, we evaluate the direct-to-ground option in terms of coverage. We show that a direct-to-ground option is a feasible solution to enhance the limited communication capabiliti...
Managers need measurements and resource managers need the length/width of a variety of items including that of animals, logs, streams, plant canopies, man-made objects, riparian habitat, vegetation patches and other things important in resource monitoring and land inspection. These types of measurements can now be easily and accurately obtained from very large scale aerial (VLSA) imagery having...
The ALOS (advanced land observing satellite) has an active microwave sensor, PALSAR (phased array L-band synthetic aperture radar), which has a fine resolution of 6.5 m. Because of the fine resolution, PALSAR provides the possibility of estimating soil moisture distributions in small farmlands. Making such small-scale estimates has not been available with traditional satellite remote sensing te...
Identification of Land Use Coverage through Ground Check GPS Data (Case Study in Tapaktuan District)
This paper investigates bias in coverage between Western and Arab media on Twitter after the November 2015 Beirut and Paris terror attacks. Using two Twitter datasets covering each attack, we investigate how Western and Arab media differed in coverage bias, sympathy bias, and resulting information propagation. We crowdsourced sympathy and sentiment labels for 2,390 tweets across four languages ...
States have long been the testing ground for new models of health care and coverage. Section 1332 of the Affordable Care Act, which takes effect in less than two years, throws open the door to innovation by authorizing states to rethink the law's coverage designs. Under State Innovation Waivers, states can modify the rules regarding covered benefits, subsidies, insurance marketplaces, and indiv...
In order to measure precipitation as the main variable for estimating the runoff and designing hydraulic structures, the satellite algorithm products that have the proper spatial and temporal coverage, can be used. In this study, at first, the daily streamflow simulation of Sarough-Cahy River from the Zarinehroud basin was conducted through the artificial neural network (ANN) and ground data of...
Pointable sensor systems onboard many earth resources satellites today, particularly the higher spatial resolution sensors, provide for a near infinite set of collection opportunities. Satellite orbits of these systems are not systematic repetitive tracks. Predicting future collection opportunities requires predicting where the satellite will be and then computing the potential swath coverage f...
The National Aeronautics and Space Administration (NASA) Glory mission, a remote sensing Earth-orbiting observatory, which is now scheduled for launch in October of 2010 [1], as part of the A-train constellation (705 km altitude, 98.2 degrees inclination) Sun-Synchronous orbit. The Aerosol Polarimetry Sensor (APS), the primary science instrument onboard Glory, will collect multi-angle, multi-sp...
