All Points Blog has an editorial asking “Who’s Responsible for Map Data?“. From the text : “Back in the day we were the only ones to see this data; today its streaming all around the globe for billions of eyes to see and potentially “correct.” I hope the mapping portal operators and their data providing partners will take seriously the need for processes to receive and react to these [correction] requests. Further, they need to as transparent about their decision making as possible to help end user and mapping portal hosts to make the best choices.“

MercuryNews runs a story (Free registration required) on a Stanford University academic initiative to make GPS positionning more precise and more available. From the article: “The interdisciplinary research center wants to create a navigation system capable of locating objects within one centimeter, or less than half an inch. The center hopes to achieve that goal within the next 20 years. … Tom Kenny, a professor of mechanical engineering, also is working on silicon oscillators that could improve the reliability of a GPS device. And electrical engineering professors Umran Inan and Arogyaswami Paulraj are trying to create much smarter antennas to improve GPS reception in a variety of hard-to-locate places, even in the presence of jamming devices.“

LKS writes “Looking again at back issues of Earth Observation Magazine, I came across this article on using hyperspectal remote sensing for mapping minerology.

Hyperspectral imaging uses a wide range of spectral bands to measure the reflectivity and/or absorption of the surface. From the article - ‘Subtle mineralogical differences—often important for distinguishing between rock formations or between barren ground and potential economic ore—are often difficult to map in the field. Hyperspectral remote sensing, the measurement of the Earth’s surface in up to hundreds of spectral images, provides a unique means of remotely mapping mineralogy.'”

GISuser features a press release by QUALCOMM about the wide adoption of gpsOne solution. The announcement states that “more than 150 million handsets featuring the gpsOne solution [were] shipped and more than 250 different handset models from more than 40 manufacturers [are] commercially available. … The gpsOne solution provides the performance and solution flexibility to support a wide variety of consumer and enterprise location-based - and location-enhanced - services, as well as emergency services for the North American E911 emergency mandate. The gpsOne solution was first deployed in and has realized market penetration and utilization unmatched by any other GPS provider.“
