Discussion: green triangle

green triangle = small grouping of black sticks
somewhat similar to #8 which was tree root mound = mound of sawn timber.
Going without descriptions forces one to be very exact with one's nav.

Ok, wow. I don't remember any black sticks! Anyway next time I'll take the codes.

Do control descriptions help when you have a symbol on the map that doesn't correspond to ISOM? Perhaps the description for a stick pile might have been something like {=}

Green circle cherry tree, green triangle cherry tree cluster. Sunday's cluster looked more like blackened sticks. They were still vertical though, so {||} might be more appropriate. Wouldn't matter what the descriptions are if you don't take them.

Special Newcastle symbols??

One of a number :)

Fairly sure the sticks were the remains of the cherry tree cluster. But navigating using other features very adjacent plus flag very clear would not have proved any challenge to well experienced orienteers such as those doing a 5.1km Hard course.

I always do the longest, hardest course available but doesn't mean I'm any good at the sport ;-)

You are better than most!

Leaving aside the fact that this actually wasn't the World Championships or a WRE (so ISOM doesn't apply), the green triangle is one of the new symbols proposed in the awful proposed ISOM 201X.
So Newcastle is ahead of the game there. I think special symbols can add a lot of value to mapping and I welcome their use.
However I do struggle with identifying particular species of trees (e.g. the snottygobble in WA), plus there is the issue of the fact they can grow (elsewhere, not mapped) and fall down or get burnt (where they are mapped).
Australian native bush has a lot of different kinds of trees of many different colours: I think I'll have to live here a few more decades before I can tell a cherry tree from a gum tree, acacia or wattle.

The native cherry tree is nothing to get very excited about. Most times it looks pretty straggly but when reasonably healthy has a very distinctive green colour to its foliage (which is like pine needles) and hence deserves the title of distinctive tree.
O-ing - would like to think you would stay a few more decades!!! and keep orienteering so well.

From ISOM:
It is the aim of the International Specification for Orienteering Maps (ISOM) to provide a map specification which can accomodate the many different types of terrain around the world and the many ways of doing orienteering.

These specifications should be read in conjunction with the rules for International Orienteering Federation (IOF) orienteering events. For IOF events deviations are permissable only with the sanction of the IOF Map Committee (IOF MC). For other events such sanction must be given by the national federation. In addition, there are supplementary specifications for other orienteering disciplines on the basis of the specification for foot orienteering maps.

Doesn't mention anything about it needing to be a WRE to conform to ISOM.

You bolded that section thinking it might apply to the Newcastle League?? It doesn't. It applies to the types of events listed in the dreaded IOF rules.
Aug 24, 2016 11:46 AM # 
Well excuse me for trying to make maps consistent across different jurisdictions so that people can understand them!
Aug 24, 2016 12:25 PM # 
Well I applaud Newcastle for making the best maps, suitable for their terrain and level of event.
Aug 24, 2016 9:03 PM # 
We do remove or hide Newcastle special symbols when we have more major events so that maps are consistent with rules/standards.
Aug 25, 2016 12:37 AM # 
But then you wouldn't be conforming to O-ing's 'Do what you like' rule that applies to all events outside of IOF regulations. I expect to see green triangles, red squares and pink dodecahedrons on the Christmas 5 Days maps this year otherwise I won't be satisfied.
Aug 25, 2016 12:46 AM # 
I'll try to come up with something special for the Glenrock mountain bike map. Maybe related to the bits of old building material that stick out of the ground where they dumped stuff from the earthquake clean up. But I can't spell dodecahedron so don't know how I could draw one. Or maybe for those gaps on the downhill sections that would result in most MTBOers having a bike the shape of a dodecahedron it they attempt the jump.

'Do what you like' is not a rule, its a guideline. And I didn't say it - you did.

As you are no doubt aware, seeing how keen you are on the IOF, the proposed IOF ISOM 201X says:

The base scale for an orienteering map is 1:15000. The scale 1:15000 is used for all long distance competitions. For shorter competitions, enlarged maps with a scale of 1:10000 may be used. For older age groups (age classes 45 and above) where reading fine lines and small symbols may cause problems due to deteriorating vision, enlarged maps are recommended for all formats. Enlargements to the scale 1:10000 is recommended for the youngest age groups (12 years and below) where the capacity of reading complex maps is not fully developed.

Generalisation shall follow the requirements for the scale 1:15000 in all cases. Terrain that cannot be legibly presented at a scale of 1:15000 is not suitable for international orienteering events, but may be suitable for international sprint orienteering events

This is madness. Not all terrain can be best mapped for 1:15000. The sport is bigger than IOF and Newcastle is to be congratulated on mapping the terrain appropriately.
Aug 30, 2016 5:10 AM # 
Okay I agree with you on that last one and I think everyone except the IOF thinks that not all terrain needs to be mapped at 1:15,000!

However your own post says you didn't know what a green triangle was given it's not a (currently) recognised symbol ;-)
