Hi, I'm not a developer, just an active contributor mostly on very undermapped
territories. Do you know if there is an open software/plugin that can assist
road extraction (vectorising) from hi-res satellite image to OSM (or even that
can extract roads outside OSM that may import to OSM)? I've been tracing
almost 10.000 roads manually since the beggining of my contributions, and
thought if there is some way more technological that could save mapper's work
for visually assisting on road alignment and classification. I mean: if a
software could provide first an estimative of road tracing as accurate as
possible, I could reserve my work for checking and adjusting its alignment
where/if it doesn't fit well. Just as I do for manual tracing, since it could
be easier and faster to let me run over a vectorised road previously provided
by a software more to check in image alignment and doing classification, and
improving where it would be necessary (saving contributors work for accuracy
control more than zooming in-out + positioning + clicking for every node all
manually. For example, I've seen for long that many roads in OSM in country
side of Brazil (where I mostly map) imported by other users years ago from maps
of official sources are very out of alignment and thus useless, so that I have
to align or redo it as whole, so that if a software can vectorise roads could
be much more useful, even if it lefts some impreciosions that I could adjust
manually in sequence). I've read that Microsoft did something for road
detection in Bing: http://wiki.openstreetmap.org/wiki/Bing_road_detect_API.
I've downloaded the JOSM plugin provided there and tried to install it, but
JOSM can't detect it in the computer. Is that plugin availlable for JOSM? Is
there any other open software that can do something like that? Thank you for
any light. Sérgio (OSMuser:smaprs) [email protected]
