[Qgis-user] Separating Polygons from Polyline

[Tobias Quezada]

Since
I did not have professional/mapping grade GPS I had to result in
single frequency recreational grade GPS unit.   I have one continuous
polyline that contains both line and polygon and I would like to
“explode” it and separate the polygons and lines from that single
polyline.  Is there a tool in quantum 2.8.2 or a plugin?
Thanks
FOSS community!

It's worth noting that if the underlying data type is an 64 bit IEEE
floating point "real", in base 10 you're only getting 15-17
significant digits no matter how many digits you have in the user
interface.

If you need more accuracy than that you should probably use a BCD
type, and might want to carefully examine your data path, because it's
likely that you're fooling yourself about the acuracy of your data,
and how precision is being carried through your various computational
stages.

Re: [Qgis-user] How To overcome the limitation of real data width

[Andreas Neumann]

Hi,

This depends on the data format or database. With most databases you can 
go beyond the 20 digits. E.g. in Postgis numeric data type the limit is 
up to 131072 digits before the decimal point; up to 16383 digits after 
the decimal point. See also 
http://www.postgresql.org/docs/9.4/interactive/datatype-numeric.html


I am not entirely sure if QGIS or qt would have problems displaying or 
editing such large numbers, though - but the PostgreSQL database 
supports it.

[Qgis-user] Article on DXF export improvements

[Andreas Neumann]

Hi,

I just did a short article (
http://www.qgis.ch/en/projects/dxf-export) explaining the current 
capabilities and limitations of the DXF export of the soon to be 
released QGIS 2.10 and also yet unreleased 2.8.3 (the dxf improvements 
will be back-ported) - you can already use the nightlies to use all of 
the features mentioned in the article.


The credits go to Jürgen Fischer and Marco Hugentobler who developed 
this feature and Vevey/SIGE/Morges/Uster who paid for it.


Now in the next few months we hope that Jürgen can work on DXF/DWG 
import ;-) - and that we can come up with the funds for it.


Greetings,
Andreas

Re: [Qgis-user] Merging Shapefiles on Top of Each Other

[Tom Lennon]

Hi Tom
I betting that your merged file has NULL in the color-item you used for all
polygons from the roads source.
If that is so you could try changing the NULL color-item to a value not
included in the valid sectors color-item.
Then go to properties > style and click CLASSIFY to get the new color-item
included.
Right click the color swatch in the legend, choose change transparency and
make the color 99 percent transparent.
You can also change the outline color to be different to that of the sector
outline.
Hope it works.

Regards

[Qgis-user] Print composer crash

[Joris Hintjens]

Hello,
since recently, I cannot save a print without crashing QGIS.
I tried this both on windows7 and OX Yosemite:

Saving a map via print composer (in jpg OR in pdf!): once I click the “save” 
button, the print composer goed white and stalls.
It started wit trying to save to a A0 paper format. So I reduced to smaller 
paper size, but still the problem persists. I am now back to A4 format, with a 
300 DPI resolution, but still, no improvement.
I can use my print model only 1 time, but for the second map, the composer 
crashes. I can work again when I make a new print template.

Screen record of proces is here:
https://youtu.be/iBXwC-ebubs 


When I close the composer and go back to main window to close and restart; I 
get a crash alert on quit. Crash report is stored here:

https://www.dropbox.com/s/z8vuw45o3wqxzse/crashReport.txt?dl=0

thanks for any comment or idea to solve this annoying hickup.

Joris

Re: [Qgis-user] Merging Shapefiles on Top of Each Other

[DelazJ]

Hi,
Tom, so you have both roads and sectors in same shapefile.
To show all of them, unless you use rule-based renderer style, in
categorized style, they should have a common field filled.
Once you have set the colors for all, at the right bottom of the dialog,
you have an "Advanced" button. Use "symbol level" option to set which color
will be on top of which one...

[Qgis-user] QGIS crashes when zooming out from MS SQL layer

[Blumentrath, Stefan]

Hi,

I have a View in MS SQL containing some point data (263 points) and a int64 
primary key (qlonglong data type in QGIS), which I have loaded to QGIS (CRS: 
4326, no OTF-projection).
When I zoom out, QGIS crashes at a certain zoom level. "Zoom to layer" crashes 
every time I try. This happens both in master and 2.8.2.

When I export the layer to shape, the resulting file alone works just fine 
(some data types in the attribute table were converted)...
Both layers (shape and MS SQL) have exactly the same spatial extent.
I tried to compare the number of features in the MS SQL layer and the shape 
layer. "Count features" did not work for the MS SQL layer, but number of 
entries in the attribute table are the same...

Any ideas? Should I file a ticket?

Thanks for helping.

Cheers
Stefan

If you want one shapefile only, you might want a topologically correct
file, i.e., no overlapping polygons / boundaries. These could be created
using the v.clean function (a GRASS function available in the QGIS toolbox).

Re: [Qgis-user] Merging Shapefiles on Top of Each Other

[Tom Faro]

Hi David,

My apologies to both you and Matt as I should have been clearer. My aim is to 
merge them both so that I can use this shapefile in another piece of software 
(which will only accept one shapefile to be viewed at a time). However, what 
you are both suggesting does work perfectly if I want to stay in QGIS, so 
thanks very much for your help!

Tom

Tom,
As Matt says, you don't need to combine the roads and sectors into the same 
dataset to display them together in QGIS.  You can add both separate datasets 
to a map and you can order the layers so that the roads are drawn after the 
polygons.

Hi Tom,
Have a look at some of the QGIS tutorials (google or the QGIS website shoudl 
have some). It sounds like you just need to overlay the layers in the correct 
order, merge generally means something else.
You can drag / move the layers around / up / down in the layers window. 
Generally from top to bottom, points, lines, polygons. There is also an option 
to give each layer a level of transparency.

I have been having some trouble with merging two shapefiles – one is a map of 
all sectors in the UK and one is a map of all motorways in the UK. I have 
successfully merged them by putting them both as polygons. However, when I fill 
in the sectors with different colours the road map disappears. The same happens 
when I use the same shapefile in other software.

Is it possible to merge them so that the roads are always on top? Any Help with 
this matter would be greatly appreciated.

Many Thanks,
Tom
