Geotagging¶
Fieldwork
Some mobile devices will require for native camera mode to be turned off to enable geotagging.
To enable geotagging in case your native OS camera does not support this functionality, follow these steps:
- In QField, go to the settings and make sure Use native Camera is deactivated on your mobile device
- Completed! QField's own QML-based camera will now be utilized while taking pictures
Maximum picture size¶
Desktop preparation
The advanced settings allow rescaling the photos to a maximum width/height in QFieldSync plugin > Project configuration
Configurable attachment path¶
Desktop preparation
QFieldSync provides the possibility to configure the path of picture attachments.
- Go to QFieldSync plugin > Layers Properties
- Choose the layer, the field and configure the expression
Use expressions to specify the path of the attachments. By default, pictures are saved into the "DCIM" folder, audio are saved into the "audio" folder and videos are saved into "video" with a timestamp as name.
Additional directories can be synchronized with pictures or other attachments. Extra paths can be configured in Attachment directories. All paths are relative to the project directory.
Note
QGIS 3.14 or newer is required for this functionality
