<p>Hi Wouter,</p>
<p>unfortuantely, the area is located in Germany, well-known for its
horrible mobile networks coverages. There are some spots where you
even can't make SOS-calls.</p>
<p>So for the years to come WMS, is a bad to no option. But I'll
give it a try.</p>
<p>Cheers,</p>
<p>Bernd<br>

<div>It's possible to load a WMS layer in your project for
Q-field, maybe that's a solution?</div>
<div>But then of course you need an internet connection all the
time...</div>

<br>
I need an aerial basemap for my QField-project to be able to
locate<br>
positions. As QField has not the ability to navigate to a
point or<br>
indicate the direction of movement, provided only with a
topographic<br>
basemap, I'm stumbling through the forest and have a hard time
finding<br>
the positions.<br>
<br>
The project area is huge, around 400 square kilometers! I have
a Mrsid<br>
file of the area of 1.6 GB with 20 centimeter resolution,<br>
transformed with gdal_translate to tiff is 42.5 GB,<br>
compressed with gdal_transform with jped-compression 50% 968
MB,<br>
resampled to 40cm resolution and 50% jpeg has 295 MB<br>
<br>
I used the QField sync plugin to generate a baselayer in
gpgk-format<br>
from this ,which has 540 MB with 40 cm resolution.<br>
<br>
Unfortunately, on the tablet, the baselayer is loading so
slow, that it<br>
is impossible to work with it. Each redraw takes around 10
seconds in<br>
the small scale, rising to infinity in higher scales.<br>
<br>
I wonder if there are other approaches recommendable, for
example<br>
splitting the image into separate layers for bigger regions,
which I<br>
could then turn on and off, or if I should prepare the image
apart from<br>
using the plugins converter to gpkg.<br>
<br>
Due to the enourmous amount of time needed to process the
image on the<br>
PC, a trial-and-error approach seems not to be feasable, so I
ask you if<br>
someone can recommend an approach for such a huge beast.<br>
<br>
<br>
Thanx in advance,<br>
<br>
Bernd<br>
