There's a new OOM, version 0.6.2. I installed it and re-did the test I described on 1 Dec, but it behaves just the same. Whether by coincidence or not, it was very slow though (a) I used a bigger file than before 3.5mb with several hi-res photos behind, and (b) there are a number of random things that cause my computer to freeze up. Can anyone enlighten us about these projection issues?

Topo Map Extents – relating a map sheet to coordinates

I sometimes want to know what sheet I’m on, eg to home in on the right aerial photos. But LINZ has dropped the table they once had on their website. They’ve sent me the data and I’ve put it up on my website. It’s at Years ago when they threw the NZMS260 maps away the same thing happened, but I sometimes want photos based on them too. I’ve got those numbers at If anyone knows another link to this data let us know, it seems crazy that we should have to store it.

I use the following link to find the sheet I'm on:

If you have access to TUMONZ you can use that. The cursor gives sheet number plus co-ordinates

The JWOC sprint map has used a very light brown road infill, perhaps even 0%. And they stand out really well. This causes me to question my preference for as dark as possible. Maybe its because there is hardly any white forest or rough open, the situations where I can't see the tracks. Comment?

No preference on lighter or darker except for tracks in forest/park areas - better to show darker 'non-urban' tracks - places like Mt/Vic with steeper contours - using urban-tracks makes them very hard to read.

I do think it good to have two shades of brown to differentiate between playgrounds and concrete areas.

Notice the very strange contour shapes NE of control 17 on the M20 course where 4 contours go between two walls under a building - obviously not possible in real life - probably better to show as just a wall under the building and remove the bogus contours.

It looks like they have used 10% Michael. I didn't realise you could use 0% (white) for paved area - good to know - and could be worth testing.

I tried a range of options when trying to optimise the readability of all the bushes on my Hikuwai and Hawea River maps. The best result wasn't just the most contrasting colours which was surprising to me.

Would be good to hear more about those tests Fraser. How did you judge "best"?

Show Profile  fraser Posted: 18 July 2016, 12:18 PM  
Well I just printed out various combinations and decided what was the easiest to read. I must have discussed it and showed at least half a dozen people.

A trap for old players. IF you are using OCAD 11, and IF your eyes are not so good and you find a Windows setting to make it easier to see what's on the screen, then you may not be able to update the OCAD information notepad. The OK and other buttons on the bottom of the dialogue won't be there. (Might be dependant on Windows version, I'm on Win7. Not sure whether it happens in Win10. But OCAD has fixed it from their end in OCAD 12.)

OCAD 12 latest update now reads shape files (the easiest format for councils to provide contours in.) Previously you needed the professional version of OCAD to do this, or a messy get-around via DXF format.

The ONZ Mapping Committee is about to embark on a project to categorise this thread (and a couple of smaller related threads). This means for example that if you are interested in sprint mapping you could more easily find relevant contributions.

ONZ has provided a tool to hold the 30-ish mapping sub-topics. It is a wiki, one aspect of this is that the contents may be changed by any registered user, although this is not envisaged here. What you said is what you said; and there is plenty of scope to add another view, to challenge and disagree. Changes are in fact tracked and can be un-done by an admin user.

We hope this will increase the sharing of knowledge about orienteering mapping. If any contributor to the mapping topics has any concerns, please contact michael (dot) wood (at)

Any comments on the WOC map cartography? Good things we might not have thought of, bad or hard to interpret things?

Show Profile  Michael Posted: 1 September 2016, 4:11 AM  
The forest maps have quite a few stacked formlines. Not as "steps up a slope" but they tend to consist of one formline on the slope and then a closed formline on top. Guess a hilltop too big for a dot knoll but judged too low to be the next full contour. Is this acceptable do you think?

Have you got a link to see the WOC map you are referring to Michael?
