Will be good to have more of Finland covered so the map doesn’t have that line across the middle of it where the colour stops. I’m not convinced the previous Corine data is all that great, however. There is now decent bing imagery for some of the areas I care about and it is clear that things like edges of forests can be much improved manually from bing. It also seems to be quite generous in what is regarded to be natural=scrub. Why is natural=wood used instead of landuse=forest. The vast majority of forest in Finland is managed.

How important is it to preserve the clc:code tag if refining boundaries from bing. Sometimes, adjacent areas of forest can be merged to one area.

Did anything ever come of the possibility of importing the Maastotietokanta data that got released? Their maps are still much the best available for Finland.

I very much agree with this. The default should concentrate on streets as that’s what most people want.

Have you also added relevant paths to the Corfu trail relation, see: http://hiking.lonvia.de/en/relation/1659988 Seems to be some gaps in it still but that may be because you added them since the map was last generated.

Is good to see the improvements, though: when I went on holiday to Corfu a few years ago most of the main roads still needed mapping.

Glonass is supposed to be better at extreme latitudes and in the cases you cite: tall trees and canyons. Otherwise it just gives you extra satellites to get a signal from. Galileo should in theory make a bigger difference once it is operational. Reviews of the new Garmins with Glonass don’t seem to indicate that they are much better but that may improve with newer firmware versions.

For trees, coming back in Winter to get new GPS traces can make a big difference.

Ich habe oft natural=scrub benutzt trotz einige hochgewachsenen Bäumen. Es gibt auch barrier=hedge. Passt das viellicht zu die Feldstückgrenzen.

Ich habe es bis Darmstadt erweitert. Es gibt ein paar Fehler. Sehe:

You should tag the end node where the way continues with:
fixme=continue
noexit=no

> How long have you been using OSM?
As my primary map site for over two years but have used it a bit for four.

> Approximately how often do you use and edit OSM?

At least a couple of edits a week during the summer. Much less during the winter.

> What are your incentives for editing in OSM?

Originally it was due to the lack of any accurate maps of the local forest tracks that I regularly cycle on. These are now well mapped and I still do mapping because I enjoy it.

> What is your preferred method of attaining data to upload (e.g. GPS points, digitizing, uploading photographs)?

GPS points.

> Do you feel there is much disparity in the reliability of OSM data?

I find it fairly reliable in general. There's more disparity in terms of completeness. In Germany it is very good, especially around cities. Other places like Finland suffer from a sparse population.

> If so, do you think this could be the result of the socio-economic dynamics of an area or the method of attaining data etc?

OSM data is best where there is a large tech-savvy population. It's hard to know what effect tourists have. Greek islands I've been to are not well mapped at all but if you compare the ski areas of Austria to some of the non touristed parts in the East of the country, there's a big difference. Southern Europe in general is less well mapped.

Most GPS devices use the doppler effect to measure speed in addition to triangulation for your position. Typically, the doppler data is actually the more reliable. Often the position your GPS reports comes from the result of applying your velocity to your last known position. The effects of atmospheric conditions can also often result in an error that remains consistent for a GPS track. So when interpreting GPS results it is reasonable to apply relative offset adjustments.

I've done quite a bit of mapping tracks that follow the edge of forest where the forest was originally traced from yahoo (and I'm using a GPS). I've often found the forest edge in OSM extends just over the path. I think this is because trees extend out from their base so are bigger on the aerial pictures than you might consider them on the ground. Landsat pictures for your area may not be good enough to pick this up but you might want to keep it in mind.
