Re: [Qgis-user] digitizing

2012-06-29 Thread Andreas Neumann 
Hi,

No - there isn't.

But if you work with polygons you can automatically substract already
existing neighbour polygons. In the snap options dialogue set the "avoid
intersections" checkbox. This is even more comfortable and faster than
the tracing mode in my opinion, but it is limited to polygons.

Hope this helps?

[Qgis-user] Announce: TauDEM plugin for QGIS

2012-06-29 Thread Alexander Bruy 
Hi all and sorry for cross-posting.

I happy to announce TauDEM provider for QGIS.

TauDEM [0] is a set of of Digital Elevation Model (DEM) tools for
the extraction and analysis of hydrologic information from topography
as represented by a DEM

An this plugin is a SEXTANTE provider plugin and allows to run
TauDEM command line tools directly from QGIS using excellent
SEXTANTE framework [1].

Plugin available from QGIS Official repository [2]. Before running
it please install SEXTANTE plugin first. As this is only front-end
you also need working TauDEM command line tools. Windows
users can use precompiled binaries and installation instruction
from project homepage [0]. For Linux users I prepare small
instruction in README.TauDEM file [3], hope this helps a bit
until packages for major distributions will be available.

that's not how transformation tool (TT) works.

In TT create a transformation selecting the two CRSs (call them "A and
B" or "start and arrive", as you want) and the method (towgs84
parameters ot ntv2 grids) and save it.

Then close TT and add normally your layers. Depending on your project
CRS and the CRS of the layers you are adding, if the two CRSs will "fit"
one on the transformations you defined in TT, then a dialog will pop up
asking if you want to apply one of those transformation to the layer you
are adding.


cheers

[Qgis-user] Extract lat/long coordinate from a custom projected layer

2012-06-29 Thread Pietro Rossin 
Hi all
I'm trying to understand how Qgis handles coordinates extraction coming from
a layer that is projected by a custom transformation.

I have a list of points in monte mario Italy zone 2 - 3004 that I want to
reproject to Lat/long WGS84 with conversion between these two crs based on a
NTV2 grid file.

So, I load a xy temporary layer in a 3004 crs project and I save it as a shp
(3004).

Then I change the crs to 4326 and I use the transformation manager
(transformation tool) pluigin to adjust the on the fly reprojection from
3004 to 4326 based on the NTV2 grid file.

If now I try to calculate the lat/long values with field calculator with $X,
$y variables Qgis returns original Monte mario metric values, right?
So I must save as new 4326 shp my 3004 layer to calculate Lat/long WGS84,
right?

Saving to 4326 Qgis mantains the NTV2 transformation so I can calculate more
accurate coordinates?

Thanks
Pietro

Re: [Qgis-user] [1.8.0] Broken UTF-8 support in shapefiles - and workaround

2012-06-29 Thread Even Rouault 
Hi,

(Disclaimer: I'm a GDAL contributor)

First I'd like to say that pointing the finger at GDAL will not help improving
the situation, and we should strive for more constructive cooperation. I think
there are various issues involved and I'll try to summarize my vision of things
:
- Before GDAL 1.9, the Shapefile driver didn't have any knowledge of shapefile
encoding, and in both reading and writing operations, it took raw bytes to
read/write them in the .DBF file
- Starting with GDAL 1.9, the Shapefile driver will :
   * for write operations : recode from UTF-8 to the encoding specified by the
ENCODING layer creation option (-lco option of ogr2ogr) (or, for an existing
shapefile, from the value of the LDID field of the .dbf header or the .cpg file)
. If the value of that variable is of the form LDID/xx, then xx is written as
the LDID field in the .dbf header. If it is of another form, then it is written
as a plain string in the accompaying .cpg file. If no value for ENCODING is
specified, then LDID/87 is assumed. This value is supposed to be the "Current
ANSI codepage", a concept that doesn't make actually sense on all platforms, and
that doesn't make sense when transporting shapefiles from a system to another
one. An assumption is then made that this LDID/87 is
actually ISO-8859-1 (Latin1) and, indeed, this is strongly biased towards
Western Europe language. As far as QGIS is concerned, when creating shapefile,
it might be prudent to specify ENCODING=UTF-8 if strings passed to OGR
CreateFeature() are in UTF-8. The consequence will be that no recoding will
occur, and a .cpg file with UTF-8 in it will be written.
* recode from the encoding specified in the LDID field in the .dbf header or
the value of the .cpg file (the .cpg file has priority over the LDID field).
Several issues can occur then :
- The actual content of the .dbf may not match with the declared LDID
value or .cpg. In which case the recoding to UTF-8 will fail. This can be
gotten around by specifying the SHAPE_ENCODING environmenet variable to the
appropriate value, when it is known. You can also set SHAPE_ENCODING to the
empty string, in which case no recoding at all will occur. That might be the
solution for QGIS if QGIS want to do recoding on its side, based on user input
for example.
 - Even if the .dbf, LDID or .cpg are consistant, you can have issues if
the build of GDAL does not use the iconv library used for doing recoding
(there's only built-in conversion betweeen Latin1 and UTF-8 without iconv
dependency). Until recent fixes in GDAL (not yet released, see
http://trac.osgeo.org/gdal/ticket/4650), there was indeed a bug in the
TestCapability(OLCStringsAsUTF8) method that returned TRUE as soon as the shape
encoding was found, without checking that the recoding services were actually
available.

I hope that the working of the shapefile driver is clearer and that the QGIS
team can find the best solution on how to integrate with it.

Best regards,

Even

It lokks as if Qgis and GDAL are not talking properly to each other ;-)



Also your solution will work only in some cases, when shapefiles are
in UTF-8 encoding.


That was more or less standard with Qgis 1.7.4. So most end-users are 
stuck with UTF-8 shapefiles now displayed broken, creating new 
shapefiles with wrong encoding and may not find the solution in the 
russion blogpost mentioned in the issue #5255:



I hoped this issue would be setteled for the "stable" version 1.8.0.



So if you use in one project shapefiles with different
encodings this will not work.


The other solution would be a seperate .cpg file along with the .shp. 
But I didnt test it, and I dont know what is chosen if environment 
variable and .cpg have different values.



Also this will not work if shapefile encoding
not supported by GDAL recoding method.



Ok, then you are lost after all, but you would not get those cases from 
proper working older qgis projects anyway.
