More Lidar on OpenTopo. This time three new areas in Waikato and Bay of Plenty. Two are mostly farmland but the Bay of Plenty includes the catchment around Reparoa. Time to head back into Kaingaroa Forest if access is given? Anyone remember Tiger Country? 1993 Central Districts Orienteering Champs. I don't think the data goes that far as the map was in the far south eastern corner but worth some scouting, perhaps.

Small area of new lidar now available for the Whangarei Heads. Covers Maungatika Scenic Reserve to Bream Head. Harbour side only.

Link to a presentation from OCAD on how to convert ISSOM 2007 to ISSprOM2019 within the latest version of OCAD.

Thanks for that M. Further advice that a bunch of ONZ Mapping Committee resources including recent Mappers Bulletins are now accessible thru the ONZ Resources page. Reminder that the new sprint spec is officially "in". A number of these resources deal with the new spec, and guidance for converting existing files.

New lidar data set dropped today on Opentopo! South Auckland from Otahuhu south to the border with Waikato. Now includes the northern half of Waiuku Forest and almost to Kaiaua to the east.

For all map lovers. This website renders every single road within a city:

Not "every road". It is still reliant on data being posted on OpenStreetMap. It is one to two years behind reality (in Taupo).

Two new areas of lidar on Opentopo. An update of Christchurch from 2018 plus the lower Ashley River. Second area covers Palmerston North including Massey University.

I've used a bit of the Whangarei Heads lidar. Someone in the IT dept decided temporary features could be algorithmed out. Features like rocks the size of your van...

A new data set has dropped on Opentopo for small areas around Pokeno, Huntly, Port Waikato and near Thames. Would be worth a review for Counties Manakau and Orienteering Waikato.

Thanks for keeping us up to date with raw Lidar availability Michael. Exploring this would be an ideal lockdown job. As well as virgin areas I've found it useful for improving park mapping virtually under our noses. Some of our earliest maps were pretty bad geometrically. While the obvious errors have been fixed, and modern imagery is very good, those huge trees are just a huge blob of canopy. The vegetation height plots are much more precise.

There's a mapping channel on the ONZ Slack site ochatnz. You can sign up on the ONZ website. We should try it out - it may be better for informal conversations than the Groups, Blogs, Chats, and the ill-advised Mapping Wiki.

OChat NZ Slack details
https://www.orienteering.org.nz/ochat-nz-slack/
Wikis aren’t good for conversations – Slack or forums such as this are. We can discuss or debate things, and then pull out the key points or facts/details and store them in an organised and structured way in the separate Wiki. Kind of like a notebook that can be contributed to by many people.
A wiki is useful for multiple people contributing to a shared resource - but it relies on structure and organisation.
The wiki tool itself is deliberately flexible and unrestrictive – but an implementation of a wiki on that tool and how the tool is used needs to be organised and strict in its structure.
What is the purpose of a Mapping Wiki? My assumption is it's intended to be a knowledgebase. A knowledgebase is usually structured by breaking the material into sections and articles. When you go to a knowledgebase online it will have sections such as “printing” and then articles dealing with a “printing” concept – such as “printer errors” or “recommended printers”. Each Article in itself also has a consistent structure, with introduction, logical headings, content, cross references and references. New information is added, out of date, irrelevant, or incorrect information is removed. The history of edits can be viewed.
The power of wiki comes from the ability for anyone to use that content organisation structure to A. find the article subject they are interested in – as it can only be logically in that one place, and B. the ability to instantly contribute to the article updates with additional details or “stuff” if needed.
Rules are established and shared among contributors in Wikis – and again vary between them. Wikis have been used in many different ways – and each may have varying rules. Where to place content, how all articles are structures, and any content expectations.
