Re: [Talk-ca] [HOT] Flooding in Richelieu River, Quebec, Canada :Follow-up(Complement of information)
Hi,
Great find Daniel !
To use directly the GeoTiff images in JOSM, you could try the
ImportImagePlugin, but I haven't tried it.
I put the EO1-ALI images from Earth Observatory online, in WMS and TMS,
with the coordinates included in the GeoTiff files.
Apparently, they were not georeferenced in relation to ground control
points, but with the imagery layer shift option included in Josm, it is
not too difficult to align them to existing data. For example, a shift
of 197; -514 quickly adjusted over Venise-en-Québec seems to give a
reasonable alignment in other areas of the images too.
We could try to improve the georeferencing of the original images with
ground control points, but for now it seems that having a try at mapping
the flood extent with the current setup has higher priority. Let me know
if you think more work on georeferencing would be useful.
URLs:
For the natural color image in TMS (recommended over WMS), use the
following link in Josm:
tms:http://osm.arkemie.org/cgi-bin/tiles/1.0.0/hautrichelieu_coulnat/{zoom}/{x}/{y}.jpg
For the shortwave infrared image in TMS:
tms:http://osm.arkemie.org/cgi-bin/tiles/1.0.0/hautrichelieu_swir/{zoom}/{x}/{y}.jpg
The base WMS URL is :
http://osm.arkemie.org/cgi-bin/osm_wms?map=/mapsite/hautrichelieu.map
Thus, for the natural color image in WMS, use the following link in Josm:
wms:http://osm.arkemie.org/cgi-bin/osm_wms?map=/mapsite/hautrichelieu.mapFORMAT=image/jpegVERSION=1.1.1SERVICE=WMSREQUEST=GetMapLayers=hautrichelieu20110508_natcol;
For the shortwave infrared image in WMS:

Now on to OSM-style-collaborative-iterative flood extent mapping,
without - and probably then with - boots :)
Best wishes,

Hi all,
I've tried to put my boots on the ground without going there !-).
I found a pretty clear satellite image of the river at its max level
(30-31m) - which doesn't really changed since ...
http://earthobservatory.nasa.gov/NaturalHazards/view.php?id=50577
I made few geometric adjustments to the image and compare the result
with 30m GeoBase and SRTM contours. Geobase contours gives better
results between St-Jean and L'Île aux Noix but from there to the US
boundary, neither GeoBase nor SRTM is right.
I'm trying to produce a flooded area from DEM data while I'm looking
at an image that contains what I'm looking for - the flooded area!
Why not mapping from it? I understand the image can be used -
http://earthobservatory.nasa.gov/ImageUse/
Any idea on how I can use this GeoTiff image in JOSM?
Cheers,
Daniel

[Talk-ca] Railways duplicated in CanVec data
I've been importing in south central BC and have noticed that there is a consistent duplication of railway = rail ways in the CanVec data. No big deal as if I forget, it is caught by the validator, but there must be a glitch somewhere in converting to OSM?

Hi all,
an image interpretation of the flooded area of Haut-Richelieu has been
uploaded, replacing the first work done by Pierre (Thanks to Pierre) .It's
time to put our boots on the ground - in the water?!!

Fantastic, Daniel. Whats about a super-relation to show simultaneously the 6
relations you created?
Just a bit of insight.
I have to tell you that after three weeks of long boots, walking in the water,
we start to be a bit tired. But it's nothing as compared to affected peoples.
Some are discouraged, stressed and very emotional, isolated in their houses
surrounded by corrupted water. After more than a month, there are still
families that have to leave the house behind, because of the contaminution and
health risks.
The planning of the Grande Corvée (Big drudgery ?) to show solidarity to
these people is going very well. After last monday high waters and the
prediction of high waters for tomorrow again, the public reaction to the
various medias was spontaneous and fantastic. In three days, 3,000 people have
already called to indicate their participation at the Grande Corvée planned
for the 11-12 of june. If weather help! And all kind of propositions are made
to help affected people : Pick-up Trucks, food, psychological help, tow truck,
amphibious vehicle, chain saws, etc.

Pierre Béland
