Profile MoFa4Q

MoFa4Q is an abbreviation of "Mobile-Fachschale-QGIS" (mobile application for QGIS). This repo contains only the profile. Its installer can be found at Repo https://github.com/WhereGroup/qgis_mofa4q_installer.

Features

  • Designed for offline use
  • Reduced QGIS interface and optimized for tablet use, but can also be used in normal desktop use
  • Customized layer selection
  • Public layers (central management by administrator)
  • Integration of local or private geopackages by the user
  • Search in embedded geopackages:
    • Address search
    • Object search
  • Imprint/AppInfo
  • Toolbar:
    • Zoom in and out
    • Zoom to total extent of the geopackages
    • Ruler and surface area measuring tool
    • Object feature info
  • Print dialog:
    • Selection of print templates
    • Selection of print scale
    • Rotation of the print frame
    • Export to PDF or send directly to printer
  • Add annotations/notes
  • Using a geodata synctool to update the geodata

NB: MoFa4Q is designed for viewing data, not for editing it!

Installation MoFa4Q

The installation can be done with MoFa4Q-Installer (see https://github.com/WhereGroup/qgis_mofa4q_installer)

Synctool

MoFa4Q used all offline data, even for the background map. A Synctool has been developed to refresh and update the data. When the PC is connected to a network it is possible to check if new data is available and download it.

NB: Synctool, contrary to what its name suggests, is not a real synchronization tool because it can only download data, not upload it.

Data structure

All displayed data is stored locally in the MoFa4Q profile (geopackages folder). Inside the folder the data are separated into the following subfolders:

  • public: contains geopackages (and their QLR files) managed by the administrator and imported locally by the synctool. The user can only change their display order and visibility. Each geopackage file (extension GPKG) MUST have a corresponding QLR file. It is possible not to have more than one QLR file that has a reference to a single GPKG file. It has been decided to use 2 files (GPKG-file and its own QLR-file) to reduce the amount of data to be downloaded. For example, if only the style of a layer needs to be adjusted, you only need to re-import the QLR file.
    The sequence_qlr.yml file containing the list of gpkg's included in MoFa4Q is also located in the public folder.
  • private: contains all geopackages imported by the user (via MoFa4Q)
  • search: contains geopackages for the address and object search
  • dop: contains a geopackage regarding the background map The background layer is referenced directly in the QGIS project (in the file mofa4q.qgs).

Local customization by the user

As you can see in the diagram, additional information is stored in 2 yaml configuration files:

  • prj_conf.yaml is a custom configuration file of MoFa4Q. For example, whether debug mode is active or whether the background map is at initialization switched off. Additionally, it contains the visibility settings of the private layer
  • annotations.yaml: the list of annotations (notes) is stored here

Activating debug mode

To activate the debug mode you have to define in the file python/plugins/moFa4Q_plugin define isDebug: true
