Of course the problem is the battery duration and the precision of the gps data which, especially in the Alps mountains, can be difficult to obtain. They all work with Android tablets with the software Qfield, which is excellent if you also use QGIS as a “desktop software”.įrom their GPS reviews they are quite satisfied of the duo Android tablets + Qfield. its pictures are not the best: but I have got a Nikon D850 at work to compensateĪs regards the GPS topic of this post, at work, I often relate with Agronomists who take data in the field and collect the samples we analyze in our laboratory as phytopathologists. ![]() its CPU is a Snapdragon not an Exynos (if you read some recent reviews for the S20 Samsung series there are a lot of criticisms for the choice of Samsung to put an Exynos CPU on their S20 devices for the Europe customers instead of a Snapdragon available for USA - Corea customers).it has got excellent reviews for its battery duration (4500 mAh).it has a huge display (6.7 inch) which is a must for GIS stuff. ![]() it also has gps dual band frequency, to improve the precision of the gps signal (this feature is reported as missing in the Google smartphones Pixel 4 series, which is a pity because they were on my top list as smartphones…).it has: A-GPS + GLONASS+ BeiDou + Galileo (quite useful in Europe).it is cheap (around 330 euros, in Italy): most important factor!.I am oriented to buy a Samsung Galaxy A71 for several reasons: I am a phytopathologist by trade and I am also very far from being an expert on this topic Hello cannot help you for GPS comparison of modern smartphones For those that do not (my 2 DSLRs), I am glad of some, albeit imperfect, functionality. Some cameras have built in geo-tagging - i.e. I don’t see my new hardware toy as a geo-location panacea, more as part of my toolbox. This happened to me for months after moving at the end of last year - Google kept insisting I was at my old home whenever it synched with my home wifi. The most significant errors can be down to people moving house and Google insisting that the wifi with certain MAC address is in the previous location. Allowing Google to use wifi as well and selling my digital soul to them is the only way I have found to get reasonable (but still sometimes spectacularly wrong) location data. Nevertheless, I have found that A-GPS only on a Samsung handset is woefull in terms of continuous location - impossible to use a drive-navigation ap with. It is true not all smartphones are created equal and not all IT behemoths lock you in to the same degree of privacy invasion. If I had bought a genuine Nikon product (not available anymore, but priced at least 4 times as much when they were) I would expect much better yet the reviews I have read (including yours above) suggest that this is one instance where Nikon put their name on something shoddy. As for loss of signal and the like, I am quite reconciled to the performance that goes with paying < USD 50. I haven’t used mine enough to evaluate how much it drains the camera battery, however I have only once found myself needing to ration battery-life - when I was on a 5-day overseas trip and left the charger at home. I remember asking for the ability to store presets as a feature request (see this thread), and was thrilled at how quickly it was thanks for the caveats. This is why, absent specific embedded geolocation (or darktable being able to apply my GPX track), I end up using the presets I have stored in “find location” in map view. If I was last at that location some weeks or months in the past, can I remember exactly when? To be honest, my most-used function is the “select geo images” or “select non-geo images.” Copying and pasting GPS data is useful and works well, but my difficulty is a bit of a chicken and egg situation: to tag a new image I need to copy the location from a previous image at the same location. ![]() Thanks, I noted those at the time and have your geoToolbox enabled in my darkroom view.
