Mapping

Show Profile  Jamie Posted: 10 May 2009, 7:38 AM  
I normally stay away from your peoples mapping thread, because mapping scares the hell out of me...

But that is priceless..."How can we pull away young people from other sports and convince them to run these crazy courses"...!!! It reads like something made up by Paul to stir the pot, but too ridiculous.

On the mapping bits I feel that I have run on some damn good maps with detailed contours in my life, whats broken?

The evaluation report on the 2008 year maps was compiled by Sergio Grifoni, an Italian member of the IOF mapping Commission.
If anyone should like to send him a message, his email address is: sergio.grifoni@eutelia.com

Yeah like " where exactly did you get that 'Tea' from at your party, and is there any left man?"

Thought some of you might find this interesting:

A great source of info Tane. In particular the Orienteering/North America article is a very readable summary.

I suspect however that the picture of US topo contours overlaid on some LIDAR-derived contours presented by Kommentator O'Kansas contains a fallacy. That is that the more detailed set of contours is correct. Many of the wiggles in LIDAR contours may be spurious. Occasionally Stewart Hyslop's photogrammetry shows wiggles that you can't see on the ground, but having a human involved is effectively a "reasonableness filter" which might not be there for LIDAR contours.

Tane, Thanks for putting up that link. After the OCAD session here on Tuesday I got a hankering to find out more about LiDAR and it's pros and cons. Michael's comment about spurious wiggles will probably be backed up by more research and fielwork.

LiDAR seems to have quite a few applications particularly in Robotics and for Military applications such as UAV's so I guess the technology will develop and improve rapidly...but hopefully not to the extent that the machines take over...otherwise it will be down to John Connor to save humanity!

Occasionally I want to run two instances of OCAD at a time. Sometimes the second one appears to start, but when you try and open a file the hourglass appears and nothing happens. The blue bar at the top says "not responding". I can exit OK by clicking "X".

Anyone else get this? I'm sure I always used to be able to run two OCADs at once. But maybe not since I got Vista. OCAD was once reputed to "run on a Casio watch" so I hardly think that two OCADs would stress my reasonably up-to-date computer.

Do you mean you are trying to run two different versions of OCAD at the same time or two different Windows at the same time? The latter should work OK, but you can only see one Window at a time (full screen) unless you slightly minimise the Windows.

I remember my computer suffered indigestion if I tried to have OCAD7 and OCAD8 open at the same time.

Show Profile  Michael Posted: 30 June 2009, 3:55 PM  
Well both. When frequently moving from one map to another its easier to alt-tab between two OCAD windows than to use the OCAD window menu. (Or is there a one-click way to toggle from map to map within an OCAD session?)

And then there's sometimes a need to run two different versions of OCAD at once.

My (Uni of Canterbury, actually) year-old laptop which is supposed to have specifications so that I can run anything on it definitely doesn't like having two ocads open at once. Sometimes it might handle it for a while but tends to crash more often than not.

Show Profile  Martin Posted: 30 June 2009, 7:27 PM  
I haven't had any problems running multiple instances with Vista, using both Ocad 8 and Ocad 10 Std.

Show Profile  Michael Posted: 30 June 2009, 7:33 PM  
XP or Vista Jenny? What version(s) of OCAD are you running?

I'm on Vista Business, using OCAD 9 with occasional 8.

Show Profile  Jenni Posted: 30 June 2009, 8:48 PM  
It's just XP and OCAD 8

I do think that a lot of issues I have with memory on my laptop are due to all of the compulsory uni software which is installed on my laptop. Eg when I shut down tonight it asked to"Install updates", which I usually put off but I thought I better do it and when I gave up and went home it was installing the 4th of 24 updates! So probably my laptop isn't a particularly good comparison. Definitely whenever I try to have a virtual machine running as well I struggle to get OCAD to run reliably or anything else significant. It doesn't seem to me that OCAD could run on a casio watch though.
