Title: iOS version - GeoPDF and maximum zoom
Post by: brett on May 14, 2026, 08:52:58 AM
I've just found OruxMaps after searching for an alternative to the no-longer-free Avenza Maps that supports GeoPDF. (All topo maps here in NSW, Australia are available free in GeoPDF format.)

I'm very impressed that importing GeoPDF *just works*! I'm looking forward to trying this out on an upcoming hike.

However, there appears to be one issue: zoom in is quite limited, and not really sufficient to see detail on these maps. Is there a reason for this constraint, or a setting to change the maximum zoom?

Hello, I have compared my geopdf between the two versions of OruxMaps (iOS/android) the same map on iOS reaches up to zoom 15 and on android up to zoom 17. I think you are right that there is some limitation or you simply have to improve the iOS version greetings troNpo

I've just compared the maximum zoom using the iOS built in PDF viewer with OruxMaps. I also compared the same zoom in OruxMaps and the builtin viewer.

Notes:
(1) The OruxMaps maximum zoom is not enough

(2) Even at the same zoom, the OruxMaps rendering is blurry

The tip about moving OruxMaps data to the public folder and then refreshing/reloading profiles is especially useful. It can save a lot of trial and error when setting up OruxMaps on Windows via WSA.
