A sensible proposal

Posted by Unusual User Name on 20 December 2011 in English.

I found a post over on legal-talk, “A gradual transition to ODbL” that I think is a very sensible proposal, which so far has no responses to it.

http://lists.openstreetmap.org/pipermail/legal-talk/2011-December/006789.html

I imagine if you’re reading this diary you’re aware of the license change over date of 1 April, and the accompanying loss of data that will involve. You might even be aware that at a worldwide level it’s only a few percent of the database that will be expunged. There’s a short history as a footnote below if you’re not aware of this.

But for Australia, Poland, many regions of Germany, and another dozen or so countries there is a very real risk that large chunks of data will be lost in the license changeover. For details see here http://odbl.poole.ch/. But even if your country looks relatively safe, there are probably regions or towns that are at risk of being badly affected.

Re-mapping, for example, Australia by 1st April, is just not possible, I’ve been busting a gut doing my share and it can’t be done. There is an outside chance that some licensing issues can be resolved and rejectors coaxed to sign up, but I wouldn’t be banking on it. I wouldn’t base my future plans around it.

You could well say re-map before it goes, re-map after it’s gone, same difference. But that’s ignoring the psychological aspect. There are lots of mappers out there who probably have only the vaguest idea that a license change process is happening, and hardly imagine that it will have any real impact on them. When they log on after 1st April (depending where they are) they are going to be disillusioned at the data loss in their area and quite possibly discontinue mapping.

See full entry

The state of Queensland, Australia has a bucketload of railways (lines platforms, pedestrian access) that were not traced by license acceptors, and so will disappear in the license change if not re-mapped.

They're on my to do list, but I have a lot of other things on there as well, and will have less time over the Christmas break.

Some tempting places to work might be:

Gladstone, the port, the coal terminals (world's fourth largest coal export terminal), and the main line heading south

Dutton Park, a largish junction, and suburban lines heading E and W from there. (This junction is partially re-mapped.)
osm.org/?lat=-27.49532&lon=153.03153&zoom=17&layers=M

Acacia Ridge multi-modal terminal, and the main line heading N and S from here.
osm.org/?lat=-27.5797&lon=153.0325&zoom=14&layers=M

Port of Brisbane terminal.
osm.org/?lat=-27.38453&lon=153.17399&zoom=15&layers=M

Roma Street Station, 8 tracks close to the city centre
osm.org/?lat=-27.46424&lon=153.01835&zoom=17&layers=M

Bowen Hills Yards, really big
osm.org/?lat=-27.44369&lon=153.03685&zoom=16&layers=M

If you're tempted to help out, remember, please no copying across of line name or platform number unless you can find a legit source or have local knowledge.
I (or some other local) can easily add the line names later.

Please leave the station nodes for now, unless you have a legit source for replacing them. They'll be useful up until the license changeover, and I (or some other local) can use local knowledge to replace them later on.

Remapping is boring

Posted by Unusual User Name on 19 November 2011 in English.

Remapping is boring, and takes away time from doing real mapping.

However, with 1st April date to expunge non licence compatible data from the map, it is not too soon to start remapping.

In Australia, only about half the map is compatible with the new licence conditions. About a quarter is the IP of 44 licence rejectors, and the remaining quarter is made up of about 1,500 non-acceptors, who are signing up at the cracking pace of around .22% per week. It's clear I can't wait for the non-acceptors to sign back in.

I've made a start on my local area, and I've quickly learnt that it's quicker to just replace stuff colour-coded as affected than to work out if the changes made by rejectors/non-acceptors are critical or not by perusing the history.

At least doing local changes, I know what the streets are called, where the bus stops are, etc, and can do it all from desktop mapping. To remap the entirety of Australia by 1st April is, I think, an impossibility.

South Korean Islands

Posted by Unusual User Name on 28 November 2010 in English.

Been amusing myself mapping South Korean islands near the North Korean border.

I was hoping to do Yeonpyeong, where the shelling occurred, but the imagery was too coarse. Not too far east though, are a number of islands with detailed imagery, and almost virgin with respect to mapping.

They're very interesting on the imagery, the sea around the islands is quite shallow and large parts of the islands appear to be reclaimed land. So you have hilly forested areas, villages nestled on the edge of that and large areas of flat fields. I'm guessing rice, but it's possible there is some aquaculture too.

I've just better traced the coastline and put in tracks, farmland, residential areas, the odd water body and school areas based on existing point data.

However, the rendering of my mapping doesn't look that exciting. Of course, the coastlines will take probably a month before they render.

Dutton Park, Queensland

Posted by Unusual User Name on 22 June 2010 in English.

Dutton Park, Queensland is now complete, at least as far as I'm concerned. All building outlines and street numbers are in, although the last couple haven't rendered yet.

On an unrelated note, I think I damaged the West End/4101 boundary the other day. Labels are now appearing on the boundary line, not in the centre.
The area I was working on was the southern boundary along the river, if anyone has the skills and energy to find the problem and fix it.

Of course, it may have been broken before, but I didn't realise it.

I still haven't finished Fairfield yet.

Location: Dutton Park, Greater Brisbane, Queensland, 4102, Australia

Things I've been doing...

Took a holiday to Mapleton and picked up a dozen or more street names in the area.

I declare my Kampong Ayer project complete, except for that I've made contact with a lapsed Brunei mapper in the hope that he might be able to fill in and verify a few things.

Finally finished all the address numbers along my 5 km cycle commute. (Fortunately some of it is through parkland). Time to start making diversions to pick up more.

Found some interesting structures along the Brunei coast, and started tracing the coastline around them. (somebody else had made a start). My changes haven't been rendered yet, but you can see the earlier work.
