ReadSDB plugin for QGIS 3

QGIS plugin to plot data from SDB structural database on the map or stereonet.

The plugin reads data from SDB structural database (SQLite3 database created by PySDB manager). The plugin provides the following functionalities:

1. Read data based on several criteria, including active selection in localities layer.
2. Can automatically correct symbol rotation according to grid convergence and magnetic declination (using NOAA data).
3. Contains a basic set of SVG symbols used by structural geologists.
4. Plot selected data on Stereonet using APSG python package for structural geologists.

Install instructions

Download the ReadSDB plugin from GitHub and unzip into the python/plugins folder of the active user profile. The location of profile folder could be find using the menu Settings ► User Profiles ► Open Active Profile Folder.

Dependency requirements

Note:All dependencies must be installed within QGIS3 python environment:

• numpy
• scipy
• matplotlib
• pandas
• sqlalchemy
• apsg >= 1.0

On Debian-like Linux distros use apt:

sudo apt install python3-pip python3-numpy python3-matplotlib python3-scipy python3-pandas python3-sqlalchemy

and install APSG using pip into user space:

pip install --user apsg

For Ubuntu 23.04 and later Canonical blocked installing or uninstalling pip packages. One possibility is to force pip to install apsg:

pip install --user apsg --break-system-packages

On Windows, numpy, matplotlib, scipy and pandas are already installed with QGIS, so we need to install apsg. Open Python console in QGIS and run following commands:

>>> import pip
>>> pip.main(['install', '--no-deps', '--user', 'apsg'])

Restart QGIS and enjoy!
