OGR seems even more cryptic than proj:
ogr2ogr -t_srs "+proj=utm +zone=17 +datum=NAD83" -s_srs WGS84 outfile-utm.shp infile-geo.shp
Note the weird output-first convention. Check your UTM zone and datum. This approach seem to work for GPS tracks saved as GPX and converted using gpx2shp.
I do a lot of work with UTM survey locations, and quite often I want to have them stored in my GPS. I used to rely on a powerful but oh-so-clunky Windows application called Corpscon, but I really didn’t want to be limited to Windows machines, and Corpscon really only works for North America.
And then I discovered proj. While it has a pretty hideous command-line syntax, the output matches Corpscon to the sixth decimal place. Say you had a waypoint stored (for Southern Ontario, UTM Zone 17, NAD83) like this:
4843744 443025 Goderich
that is, UTM northing,easting, followed by label.
To convert this to geographic coordinates, you’d invoke invproj (which goes from UTM to geographic) like this:
invproj -E -r -f "%.6f" +proj=utm +zone=17 +datum=NAD83
and it would spit out:
4843744 443025 -81.707611 43.744546 Goderich
Columns 3 and 4 are the geographic coordinates – 43Â° 44′ 40.37″ N, 81Â° 42′ 27.40″ W in more familiar notation – which is in fact a location between Brock St and Newgate St in Goderich, Ontario.
With a Unix box, proj and gpsbabel, I’m set for all my coordinate conversions.
The 365 Days ProjectÂ â€” the year-long net music weirdness that made 2003 bearableÂ â€” is back!
Catherine has a project involving Toronto’s libraries, and so I, for no particularly good reason, compiled a geocoded list of the Toronto Public Library system: libraries.gpx
You can thank MapSource for the bloated GPX file. It quadrupled in size when I changed the symbols to look like buildings.
WindShare‘s having a special general meeting tonight to discuss the following resolution:
Moved that the Board of WindShare recommends to the WindShare I membership at their general meeting of June 7, 2006, the merger of WindShare I and WindShare II for the purpose of entering into the activities necessary for the development of the proposed Lakewind Proposal.
This is quite an important step, and since I’m still in Pittsburgh, I’d hoped to vote by proxy. I was informed by the WindShare administrator that this wasn’t possible; the Cooperative Corporations Act does not allow proxy voting.
I’m annoyed by this, as it looks like WindShare is going to merge its capital with a 10MW project being built on a site with a 6.5 m/s mean wind speed. I wouldn’t develop a project on a site with this low a wind speed, so I asked the following of the board:
Can you clarify, please, that the vote can only be carried if a majority of WindShare members are present at the meeting? It would be grossly unfair if an important vote like this one was carried by a minority.
I would also like to have questions brought to the board, and if possible, the meeting itself. The LakeWind information package states that Bervie has “an average wind speed of 6.5m/s … making this an excellent site for Ontario”. I would not consider a site having this wind resource to be excellent, and it would certainly not be one that would attract a commercial developer. So my questions are:
- Is it in the membership’s best interests to develop a relatively low wind site? WindShare made their political point with the ExPlace turbine, and now we must show that community wind is economically viable.
- Would either of the potential sites be forced to curtail output when/if the extra Bruce units come online? While LakeWind would be connecting to local distribution, any generation in that area might be subject to queueing limitations.
So far, I’ve heard nothing, which makes me uneasy.
We’re not getting the best weather for the conference, but I hear that the coincidentally-running Three Rivers Arts Festival has had rain 18 out of the 20 years it has run, so noone’s surprised.
Conference hasn’t quite started yet, but the preliminary swag is quite promising; yoyos and balsa aircraft.
I spent the day in workshop run by KidWind, who have a school science kit for teaching the basics of wind turbine effectiveness. We got to build wind turbines, and test them. Here’s mine, big wean that I am:
I guess I got some losses near the hub there, but at least it worked. I was the only developer type there (there was a DoE person, and lots and lots of Pennsylvania teachers). I came away impressed, and hope I can work with Michael Arquin of KidWind to bring the project to Ontario.
(This post has the worst GPS location ever; could only get a fix to within 100m, so that’s why the map location appears to be in the river.)
So there’s a new report on wind integration in Canada, written by The Conference Board of Canada. People are picking up on it, and even the doughty Refocus quotes “… electricity from onshore wind is uneconomic in comparison with traditional alternatives“. Hmm.
So I read the report, and what do I find in the Preface?
As part of an ongoing initiative to investigate energy policy options and the future of the Canadian energy system, the Canadian Nuclear Association contracted The Conference Board of Canada to conduct a comparative study of various countriesâ€™ experiences with supporting and implementing large-scale wind projects.
So we’re expected to believe that the CNA would wish to have an objective and non-partisan report written on wind power, eh?
… [the] process is only projected to be completed by the end of this century, as it is not considered safe to start dismantling the highly radioactive core until the 2080s

I just accepted a job with Edmonton-based utility EPCOR, to be a manager for their Ontario wind projects. It’ll be based in Toronto.
(Look, I know the oM song is Good Morning Mr Edminton, but it’s too good a line to waste, okay?)
You can’t know how happy it makes me to read about the survey that shows that over 90% of people living closest to the Dun Law site supported their local wind farm. The early planning stages of this project were particularly fraught with opposition.

Oh dear, another bike lane project: Take the Tooker! – Bloor Danforth bike lane. I much prefer to go play in the traffic.
