Työaseman valmistelu

One or more pictures can be added to the feature. Here is an example of how to proceed.

Taulukot

It is necessary to set up two tables. One table where the features are stored and one with a list of pictures.

Mehiläispesä

Tieto	Tyyppi
id	Teksti (UUID)
geometry	Geometria
...

Apiary_pictures

Tieto	Tyyppi
id	Teksti (UUID)
apiary_id	Teksti (UUID)
path	Teksti, polku kuvaan
...

Relaatiot

Luo relaatio jossa:

• apiary Viitattu taso
• id Viitattu tieto
• apiary_picture Viittaava taso
• apiary_id Viittaava tieto
• strength Composition

Työkalut

Mehiläispesä

Aseta kentän tunnuksen oletusarvoksi uuid() tai käytä UUID Generator -työkalua. Sitä ei tarvitse näyttää lomakkeessa.

Aseta relaatiotyypiksi N-1 relaatio ja lisää relaatio lomakkeeseen

Mehiläispesän kuva

Aseta tiedon polkun tyypiksi Liite työkaluun ja lisää se lomakkeeseen

Drawing and sketching

QField have an in-app drawing and sketching functionality enabling you to directly sketch over and annotate images captured while in the field as well as drawing on top of a blank canvas or over a template.

Geokoodaus

Maastotyö

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:

1. Siirry QFieldissä kohtaan Asetukset ja varmista, että Käytä alkuperäistä kameraa on Ei-aktivoitu mobiili laitteellesi
2. Completed! QField's own QML-based camera will now be utilized while taking pictures

Fetching Geotags (EXIF) from the image file into the attribute table

Työaseman valmistelu

Sometimes you might be interested in automatically storing Geotags such as the latitude, longitude, orientation, etc. This information is also known as EXIF tags.

To store the EXIF information, follow these steps:

1. Add an attribute per EXIF tag in the table that contains the pictures.
2. In the pictures form, configure the default value of each attribute to the corresponding EXIF expression See QGIS EXIF function, and make sure Apply on update is activated.
3. The EXIF tags that QField can capture are listed in the QGIS documentation (link above). However, this list might slightly varies depending on the mobile characteristics.
4. Capturing EXIF tags requires accessing the full physical path of the picture. Be sure to reflect this in the QGIS expression. For example, the expression exif(@project_folder + '/' + "path", 'Exif.Image.Orientation') retrieves the orientation of the picture stored in path.
5. Completed! QField's now capture and store the EXIF tags in the pictures table while taking pictures.

Työaseman valmistelu

The advanced settings allow rescaling the photos to a maximum width/height in QFieldSync plugin > Project configuration

Konfiguroitava liitteen polku

Työaseman valmistelu

QFieldSync provides the possibility to configure the path of picture attachments.

1. Go to QFieldSync plugin > Layers Properties
2. Valitse taso, tieto ja määritä lauseke

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.
