Comment Might have better luck with a lesser known journal (Score 1) 279

Hi, that sounds like an interesting and useful algorithm. You may have better luck trying to publish in a smaller, specialty geomatics journal. Also, you probably would do well to find a credentialed co-author. If you're in Canada or interested in publishing in canada the best journal for this sort of paper would be the Canadian Institute of Geomatics's quarterly Geomatica ( Good Luck, I look forward to seeing the published paper.

Doesn't matter.. you aren't going to get better than 10m accuracy without DGPS and 1m with it. Surveys have to be right to centimetres - no GPS can do that (possibly some of the military stuff, but I'd be surprised if even they were that accurate).

You don't need military GPS to be that accurate, it can be done with differential phase GPS. See: here. By using a fixed base station at a location with known coordinates, one can expect to see accuracies in the 1 to 2 cm range as long as the receiver is within 10's of km from the base station. There are several manufacturers who make gear that can achieve this level of accuracy, see Leica, Magellan, and Sokkia. I've been using Leica gear at work mostly, and have see ~1cm accuracy under good conditions pretty consistently. A lot of legal surveying in remote areas is done exclusively with GPS, especially in the northern parts of B.C and Alberta. I've done legal surveys with GPS in the Vancouver area, but getting high accuracy in urban areas is more difficult because of multi-path noise and qoor signal quality from obstructions such as buildings. Also people in the city get mad when you cut down trees to get better reception ;)


Submission + - Power-generating spacesuits

Maggie McKee writes: "Could piezoelectric sensors help power future space missions? From the article: "Astronauts' spacesuits may one day be covered in motion-sensitive proteins that could generate power from the astronauts' movement, according to futuristic research being conducted by a new lab in Cambridge, Massachusetts, US. Such 'power skins' could also be used to coat future human bases on Mars, where they could produce energy from the Martian wind." Eventually, the biologically derived suits might even be able to heal themselves."

Submission + - Jean Ichbiah, Chief Architect of Ada, Dies

An anonymous reader writes: Jean Ichbiah, the chief architect of the Ada programming language, has died ( Although Ada is not widely used today outside of DoD, the language introduced a generation of programmers to practical language constructs for what had until then been esoteric features such as overloading, exception handling, and multi-tasking.
