Thank you for this Michael.
Driveways are an interesting case - they are an obligation for the
Vegagerðin *as long* as it is a residence. However if it is no longer a
full time residence it is stricken of their list of maintained roads.
Thus we can have these smaller roads appearing and disappearing from the
official data.
We will look into your observations.
Regards,
Jóhannes

Komið þið sæl og blessuð.
My Icelandic language skills are not good enough to write a letter so
I’m writing my message in English.
I did in the last time a road network analysis on OSM Iceland data.
Here I checked with the road list from vegagerdin
http://www.vegagerdin.is/vefur2.nsf/Files/Vegaskra_2015/$file/Vegaskra_2015.xlsx
, if the roads and segments of roads are mapped correspondingly to the
list.
As mapping basis I took the information from the OSM Iceland Wiki.
Unfortunately this wiki wasn’t actualised in the last years, probably
because it’s an awful manual work. I don´t know if there exist a plug
in to actualise the road list in the wiki with a set of
Overpass-queries. The information there is included in OSM, but not
extracted and processed to the wiki yet.
In the road list from vegagerdin exist a new road network type "Sx".
The Kjalvegur for example has this network type. I understand it as
primary highland route, but left the mapped road as it was.
I focused on the 1 to 3 digits road reference numbers, the four digit
roads I only looked at, when I strolled over it. When I found
information about the road, mostly in OSM I tried to fix it immediately.
A few roads I found which I couldn’t identify in OSM. The road might
exist with a different name and without the mapped reference number.
As I can’t state a fixme statement on elements which I didn’t find, I
list the roads here:
378 01 Skíðaskálavegur Hringvegur (1-d8), við Skíðaskála Hringvegur
(1-d8)
413 03 Breiðholtsbraut Reykjanesbraut Hafnarfjarðarvegur (40)
419 01 Höfðabakki Reykjanesbraut Nesbraut (49)
419 02 Höfðabakki Nesbraut Hallsvegur (432)
470 01 Fjarðarbraut Hafnarfjarðarvegur Hafnarfjörður,
Lækjargata
470 02 Fjarðarbraut Ástorg Hafnarsvæði
470 02 Fjarðarbraut Hafnarfjörður, Lækjargata Hafnarfjörður,
Hvaleyrarbraut
628 01 Hjarðardalsvegur Vestfjarðavegur (60-43) Hjarðardalur
713 01 Hvítserksvegur Vatnsnesvegur (711-05) 711-05 Hvítserkur,
bílastæði
757 01 Villinganesvegur Skagafjarðarvegur (752-03) Villinganes
830 02 Svalbarðseyrarvegur Hringvegur (1-q2) Svalbarðseyri,
Laugartún
845 02 Aðaldalsvegur Staðarbraut (854-01) Norðausturvegur (85-03)
846 01 Austurhlíðarvegur Hringvegur (1-q8) Stóru-Laugar
859 01 Hafnarvegur Húsavík Norðausturvegur (85-05) Hafnarsvæði, endi
gangbrautar
865 01 Gilsbakkavegur Norðausturvegur (85-12) Gilhagi 1
897 01 Svalbarðstunguvegur Norðausturvegur (85-24) Fjallalækjarsel
942 01 Steinsvaðsvegur Borgarfjarðarvegur (94-04) Stóra-Steinsvað
942 02 Tjarnarlandsvegur Steinsvaðsvegur (942-01) Tjarnarland
948 01 Gilsárteigsvegur Borgarfjarðarvegur (94-03) Gilsárteigur 1
949 01 Þrándarstaðavegur Borgarfjarðarvegur (94-01) Þrep
2284 01 Sólheimahjáleiguvegur Mýrdalsjökulsvegur (222-01)
Sólheimahjáleiga
2285 01 Ytri-Sólheimavegur Mýrdalsjökulsvegur (222-01) Ytri-Sólheimar 3
2286 01 Ytri-Sólheimavegur 1 Mýrdalsjökulsvegur (222-02)
Ytri-Sólheimar 1
7079 01 Núpsdalstunguvegur Arnarvatnsvegur (578-05) Núpsdalstunga
The following roads mapped in OSM I couldn´t find in the road list
from vegagerdin or the mapped road don’t correspond with the
information in the vegagerdin road list:
882 01 Leyningshólavegur Villingadalsvegur (8370-01) Leyningshólar
915 Vesturárdalsvegur
2001 01
There are lots of roads in the list, where I couldn’t find the places
from the list, especially when the road leads to a farm or house.
The list also gives the road length, where the length is measured over
ground I guess. OSM has no elevation in the map so the measured road
length is as the ground would be flat. The difference between these
values should be under 10%. Unfortunately the difference on lots of
the roads is much higher (up to 50%).
One reason for this could be that the road with certain reference
number is much further mapped as vegagerdin states it. But on some
roads also the mapping quality might be poor. But also on these I
didn’t focus. I might try to improve the map in future when there is
some time for it.
Also I realised that outside Reykjavík in the villages most of the
schools aren’t mapped. The schools are used in summer as guesthouse,
so only the tourist infrastructure is mapped. Is this still correct?
How to map this in OSM?
I hope that the Icelandic community have a look on some of the items.
Gleðileg jól og farsælt komandi ár
