Hi Andreas,
Thanks for your detailed response and suggestions. I will certainly
consider those issues that you raised and suggestions, as well as try
NextGIS. We are really moving towards paper less fieldwork, that is why we
are exploring how tablets and QGIS can be optimized for field use. I have
limited experience in using Ubuntu/Linux OS, and for now I am more
comfortable in using QGIS on a Windows platform. Hence I preferred QGIS on
a Windows tablet. I would love to try QGIS on Ubuntu so everything will be
Opensourced.
I have tried running QGIS on our android device. I installed the QGIS
nightly in Samsung Galaxy Tab. I loaded a road map and administrative
boundary map. Everything is okay when I navigate, but when I click the
*Automatically
add point *in *Tracks* and *Automatically save added feature*, then after a
short navigation then QGIS will stop and exit.
I agree to you that QGIS on a tablet should be further improved. Anyone can
just carry a tablet device instead of the usual paper, ballpen, and GPS.
My preference on using Windows tablet is because I want to use QT forms in
QGIS as a platform for conducting field surveys. Although I have not yet
actually tried it before. But according to the blog and post of Nathan,
QGIS is working well in Windows tablet.
Hi Nathan, I really want to try QMap. Any documents or related web links
that you can share to install QMap (to have the interface like the one you
posted in your email). Right now, what I have tried is to use QT forms in
QGIS on my laptop (just to explore the functionality). I assume that
installing and using QGIS and QT is the same as installing and using it in
PCs and laptops.
Thank you,
-Leo
