A precursor paper (also available as an OGC White Paper) provides a high-level overview of and architecture for the Open Geospatial Consortium (OGC) standards activities that focus on sensors, sensor networks, and a concept called the " Sensor Web ". This OGC focus area is known as Sensor Web Enablement (SWE). For readers interested in greater technical and(More)
This paper describes the history, background, and current status of the Open Geospatial Consortium (OGC) standards development consensus process. The roots of the formation of the OGC lie in the early 1990s when a very strong market requirement for exchanging GIS data content was clearly stated. At that time, each GIS vendor had their own formats for(More)

This bulletin summarizes nearly 10 years of research related to wheat stored on farms and in elevators in Kansas. It describes on-farm equipment and pest control practices and typical storage conditions that affect grain quality. The cost-effectiveness of aeration, grain protectants, and fumigation was evaluated. Grain cooling by aeration was the most(More)
For millennia, philosophers and academicians have understood that location and the properties of location - or geography - dictate the form and function of human activity. Every human activity happens somewhere and "somewhen". More recently, scientists and researches have increasing relied on geospatial information, including observations from static and(More)
Sensor Web Services are recently emerged as promising technology and have potential usage in a wide range of application domain. However due to advancement of OGC SWE standard, the discovery and selection of Sensor Web Registry services throughout heterogeneous environment become a challenging task. Many approaches and frameworks have been proposed to(More)
Hard red winter wheat (1.4 t) at 11.1 or 13.5% moisture content (wet basis) and 20, 25, or 308C was fumigated with tablets of an aluminum phosphide formulation in unsealed, cylindrical grain bins of corrugated metal. The fumigant leakage rate was manipulated to approximate that commonly encountered in farm and commercial-scale bins of this type. Phosphine(More)
