mobile VS Mapbox GL

Mergin Maps is an option, I use it on a cellular iPad and find it good.

Try using MerginMaps for field data collection. It uses geopackages if you use their hosted service or you can set up your own and run from a PostGIS database.

If you're not finding the features/functionality you want in QField, check out MerginMaps as an alternative. It's fairly intuitive to use and they've added a lot of features recently.

If you decide you don't want to use OpenStreetMap for one reason or another, look at MergeIn Maps for field collection of data.

Best trying merginmaps.com it is a QGIS based mobile app with a very intuitive and simple interface, built-in sync tool and available for iOS/Android/Windows.

You can give Mergin Maps (https://merginmaps.com/) a try. It is based on QGIS and you can easily connect to external GPS devices: https://merginmaps.com/docs/field/external\_gps/

I suggest using Mergin Maps (https://merginmaps.com/ https://apps.apple.com/us/app/input/id1478603559) It is completely based on QGIS. Using the QGIS plugin, you can package all your layers for offline use. The benefit of Mergin Maps is that you get exactly what you see in QGIS and you can use it to collect data with other colleagues on the same project, even when offline.

Take a look at QField and Mergin Maps Input. They are essentially what you are looking for plus editing capabilities in case you need them.

I haven't used it myself, but Mergin Maps might be the kind of thing you're looking for.

Great post. By the way, one of your screenshots for https://inputapp.io is not correct. You can find more info here: https://merginmaps.com/docs/field/external\_gps/

This is the library here: https://github.com/mapbox/mapbox-gl-native

Yes, I'm using the Flutter MapBox GL project (that uses the native implementation, which is mostly written in C++). I'm using vector tiles, and it's getting down to 1.35cm/pixel for iOS and .12cm/pixel for Android at my latitude; I believe this is level 22 for iOS and 25.5 for Android.

Mapbox has a c++ sdk as well as a GL renderer

But vector tiles is indeed the way to go, but it's also much more complicated. Everyone that has worked on Maps so far has done it either as a SoC / Outreachy student or on weekends and evenings. Look at https://github.com/mapbox/mapbox-gl-native if you want to get a feel for the complexity of a client side implementation of rendering vector tiles.
