Hi,<br>
<br>
this issue is due to a choose of the spalite provider.<br>
Splite is really fast to use the data, but when add a new layer to the<br>
canvas, it need to<br>
analyze all the dataset to understand the largex bbox.<br>
To do this it could take also many minutes.<br>
After this phase it will be more fast to use it.<br>
<br>
To resolve this issue, in splaite 3.0 was added a new system table named<br>
statistics.<br>
It allow to take very fast the BBOX of a dataset without to analyze<br>
realtime the dataset himself.<br>
<br>
Unfortunately the driver splite of qgis is still to splite 2.4.0 so don't<br>
use this statistics table.<br>
<br>
But a good news is that Furieri (the author of splite) is working on a new<br>
qgis driver for splite 4.0 that<br>
will use this statistics table .<br>
and after the add of an uge table will be more fast.<br>
<br>
Regards,<br>
<br>
Andrea.<br>

Hi all,<br>
<br>
I am new to QGIS. Have spent several weeks full time trying to understand<br>
some basic features.<br>
<br>
I found it very difficult to achieve the following:<br>
<br>
Precipitation distribution (Raster image) overlayed on top of a DEM. I<br>
basically like to highlight<br>
precip-orography relationships (eg., rain shadow etc). This means I would<br>
like to set some level of transparancy in the precip layer. This is not<br>
difficult. I managed to do this.<br>
<br>
The difficulty is playing with colours and achieving a sensible legend<br>
(through print composer) for final print. When I use DEM tool to do color<br>
relief, I don't get the legend in the print composer. I could use 1-band<br>
rastor color plug-in but I am limited by color choices (the legend is too<br>
long). Colorbrewer seems to work only for vector layers (please correct me<br>
if I am wrong). So in the process I am completely last and hopefully<br>
someone will point me in the right direction.<br>
<br>
Cheers<br>
<br>

Guten Tag,<br>
ich habe folgendes Problem:<br>
Ich habe eine GPS-Fahrspur bestehend aus Punktdaten.<br>
Aus dieser Fahrspur habe ich mit der Pufferfunktion (Pufferbreite =<br>
Arbeitsbreite der Maschine; Pufferergebnis aufl?sen = angehakt) ein Polygon<br>
erzeugt. Da der GPS-Empf?nger nicht der beste ist, habe ich resultierend aus<br>
der GPS-Drift lauter Inseln im Polygon. Ich wollte jetzt eigentlich um<br>
dieses Gebilde automatisch ein Polygon zeichnen lasse. Aber weder die<br>
Funktion Polygon aus Layergrenzen noch konvexe H?lle brachten das gew?nschte<br>
Ergebnis.<br>
Ich ben?tige nur ein Polygon (H?lle) um die Arbeitsfl?che um die<br>
Fl?chengr??e zu ermitteln.<br>
Kann mir da jemand weiter helfen?<br>
Gruss Tobias<br>
<br>

Dear QGIS experts,<br>
<br>
I am using QGIS V. 1.8.0. and I have a shapefile of Argentina which I need<br>
to convert to raster. I looks as a pretty straightforward process, but along<br>
the way I hit the following problem:<br>
<br>
1) Once the vector file is loaded, I go to Raster >> Conversion >> Rasterize<br>
(Vector to raster)<br>
2) I select the output file but the following message pops up: "The output<br>
file doesn't exist. You must set up the output size to create it."<br>
3) I hit Ok and then I am left to decide what size do I want for the output<br>
file. The default values are Width = 3000 and Height = 3000.<br>
<br>
So at this point my questions are:<br>
<br>
a) What are these values for width and height? What do they represent? After<br>
conversion, I load the raster and under properties and metadata tab it says<br>
that dimensions of raster are X: 3000 Y: 3000 Bands: 1, but I am not sure<br>
what this means.<br>
<br>
Thank you in advance for your help.<br>
<br>
Luciano<br>

Hi all,<br>
<br>
<br>
<br>
I was wondering if someone knows any "easy to use" plugin in quantum gis<br>
that could be use to draw the network of animal movements from an edgelist<br>
of movements (origin - destination) and the location of farms.<br>
<br>
<br>
<br>
Any help/comment will be great<br>
<br>
<br>
<br>
Thanks<br>
<br>
<br>

Those values represent the number of pixels in the X and Y direction.<br>
<br>
So if your original vector file represents 10km by 10km then each pixel<br>
represents 3.33333m.<br>
