[Qgis-user] Problems with a projection, how to import an "el" tag in qgis

[jamesmikedup...@googlemail.com]

Hi,
I have two problems.
One is a shp file that should be kosovo, but is thousands of km away from
the osm data I imported
http://filebin.ca/wsvehh/municipalities.zip

here is the osm region
http://www.openstreetmap.org/?lat=42.57&lon=20.93&zoom=8&layers=B000FTF

Second is an elevation file I have,


There are parts 5,6,7,8 that are interesting
http://senduit.com/138b18
I have been able to merge them into one, and separate out all closed areas.
but there are partfor one there are ways that are split between files.

Is there a way to join the ways between the files? do I need to code that
myself?

I have started working on some perl scripts. But can qgis manage that? I
would like to make a colored elevation map with that, also to close off the
areas that are open.

please help,
thanks
mike

[Qgis-user] Re: Qgis-user Digest, Vol 48, Issue 36

[Carlo A. Bertelli (Charta s.r.l.)]

Hello Darren, Maxim and List,
I use the georeferencer extensively for historical maps and I
appreciate very much the new plugin.
I also think this mail exchange is very useful; I would ask even more
for the georeferencer to be great for historical maps.
To use them in historical GIS, we try to find old buildings or
significant features on ground, usually corner points carry no useful
information.
It would be very beneficial for our work to "see" the reference points
on the map canvas as a sort of temporary layer qnd even to be able to
move the target points instead of the points on the image. To ask
more, it could also be useful to save the (named) GCPS as a layer for
further reference (or "operation"). The idea behind this is that an
old survey or plan could perfectly "fit" a certain area and badly
"fit" another, so we could need switching between two or more
georeferences.
About the seemingly not substantial issue of backgroundm I may suggest
grey as a good background because white may lose the edges of white
maps, black would hide borders of precisely cut ones, grey maps are
usually brown more than grey.
Do I ask too much?
TIA
Carlo

[Qgis-user] Joining lines

[Maxim Dubinin]

Hi all,

Do we have a way to join two lines into one in QGIS? I mean really
combine them together into one, but not create a multi-feature object (Advanced
editin\Merge selected does that I believe). The lines are created with snapping.

Re: [Qgis-user] New Georeferencer

[Maxim Dubinin]

Hi Darren,

hmm, we're currently using new Georef intensively for referencing
literally hundreds of rasters to create Geotiffs.

It is not clear from the description of the first problem, whether you
cannot create Geotiff at all, or the problem is in "incorrect"
extension? We removed creation of wld in new Georef file as it is not really 
needed
when you generate Geotiff. This might be a good idea to return it
in options.

Please check out this small video as a proof that it indeed works for
referencing using corner points:
http://screencast.com/t/Mzk4NWZlNz

Regarding 2, I agree, this would be nice to be able to set.

Please open bug/feature requests on trac with clear explanations, if
you're still unable to make it work and suggested functionality.

Maxim

[Qgis-user] New Georeferencer

[Darren Cope]

Just updated to QGIS r12953 via OSGeo34W, and tried out the new
georeferencer.  It looks great!

However, a couple of comments/issues that (IMHO) bring it a step backwards
from where it was.

- I am unable to get it to output a geotiff file.  Even when the "Output
Raster" is set to GeoTiff (the only option) it will write out only a .wld
file.  This then needs to be renamed to the appropriate extension (e.g. I
was using a .png input, so had to rename .wld to .pgw)  The pluging should
create the appropriate world file type based on the output file, or actually
write a Geotiff when it says it will
- the Georeferencer background is now white.  This is not ideal when trying
to find the corners of a white image.  I often georeference images based on
corner points, and was able to do this easily in previous versions.  Perhaps
an option for background colour, or set it back to black by default?
- A question--what will the "link Georeferencer to QGIS" and "Link QGIS to
Georeferencer" buttons do (once they are operational?)

I realize this is still under active development, so hope these issues are
being fixed/considered.

Cheers,

Darren
