Hello Orux,
I'm sure you don't suffer from a lack of ideas for Oruxmaps but maybe you'll find my suggestions useful:

Possibility to geotag photos:
Sometimes the position stored in photos is wrong (e.g. due to a weak GPS signal) or there is no position stored in a picture's metadata.
In OM you can create waypoints from geotagged photos or add pictures to waypoints. I think it could be useful to write the position of the waypoint to the photo's metadata or maybe even better to have the possibility to save a copy of the picture with the coordinates of the waypoint (so the original picture will not be changed).

Creating offline maps within a border (track, imported gpx or kml)
Now it's possible to create offline maps within a rectangle (which is forgotten after the creation process) or along a path.
The function to create an offline map with a track as border makes it easier to create either maps for exactly the same region from different sources or to create an updated map when the source is updated.

Thank you for your great App
Martin

Hello friend, I think I have understood well and if not, sorry.
Geo tagging photos is possible with oruxmaps for some time now.
Just check the boxes in the waypoint settings > extension.

Then you just have to create a Waypoint in the correct coordinates and add the photo to this waypoint, in this way the photo will be georeferenced, and if it was already georeferenced it will be corrected.






For the issue of unprepared downloading, there is also another option, it is to download an area based on a track loaded on the screen.
Load the track, press the track, and download button, select map font
The app automatically downloads the zone corresponding to the length of the track
It always covers an area larger than that track.

I hope this was what you propose, if not I will join your proposal once I am clear about it.
Best regards!!

Hello Tronpo,
thanks a lot for your quick reply.
Indeed the options for geotagging photos is a feature i haven't realized up to your hint ... but it doesn't work for me.

What I have tried so far:
created a waypoint - added a photo without geotag -> neither the original photo nor the copy OM creates in the pictures folder has geo information stored in its metadata

'import waypoints from external sources' - loaded photo with wrong position as waypoint - corrected position in the map -> the position in the metadata of the original image is not changed

The settings are set as you described. I tried it with 10.7.4 GP and 10.8.0 beta 3 on a Pixel 4a with Android 13. Did you succeed in changing a picture's geotag?

This is a feature I already know. But I think this is intended for downloading maps for smaller areas because when you select e.g. a bigger region or even a whole country, the map lacks of higher zoom levels. I would prefer to have the option to chose the zoom levels (and see the size of the map before creation) just like in the map creator.

Best regards and thank you very much for your help

Strange, the geotagging of photos, works for me sometimes yes and sometimes not in GP, but never in the beta version.
I haven't done this for a long time, I will try to bring out the common factor of the problem
Regarding the map maker, it is true that it needs some improvements, such as remembering the downloaded area for future downloads, or something similar to your proposal.
Best regards

I've just tried geotagging photos with 10.7.4 GP and 10.8.0 beta 3 on my old Xiaomi Redmi 4x (Android 7, MIUI 11) and it didn't work with neither of the two versions.

Tronpo

Hello, the latest version 11.0.0beta1.
You have corrected the error, the photos added to a waypoint are georeferenced, not the urinal but the copy that is generated in OruxMaps / pictures.
Best regards

Lenz

Hi Tronpo,
thanks for your note on the bug correction. It works perfectly now when you create a waypoint and add a photo to it. It doesn't work when you have a waypoint with a photo and move the waypoint on the map - but probably that was not intended. Nevertheless a great feature.

Can you confirm that creating a waypoint and adding a photo from the OM pictures folder destroys this photo (the result is a 0 byte file)?

Best regards
Martin


Oh ... I'm a bit disappointed that OM can't georeference urinals ... but I love the phone's auto correction ... at least when I'm not it's victim ;)

Well, I added photos from the OM pictures folder to a wp, and it hasn't been destroyed.
I did different tests, make a photo waypoint, create a wp and add the photo of the previous photo waypoints.
Move photos to the pictures folder and add them to the reference point.
No photos were destroyed.

Hi Tronpo,
I can reproduce it using this (maybe unusual) method:
  • I create a waypoint and add a photo from the camera folder -> OM copies the image into its picture folder
  • I realize that the position is wrong and delete the waypoint
  • I create a new waypoint and add the copy (from the OM picture folder) of the original photo -> I get a 0 byte file

This only happens when a photo already belonged to a waypoint.

Well, I follow your steps Strictly speaking, , but the photo remains, and acquires the new position.
Everything seems correct.

After some testing and with the help of Tronpo here's the solution:
The problem only occurs when I select the photo with the app Simple Gallery Pro. When I select it via my phone's native file manager or CX File Explorer, everything is OK.
I didn't do any testing with other gallery or file manager apps, so I don't know how they work.
