Warning: This package is not currently maintained and may not work without some additional technical care. It looks like a newer version of QGIS has changed a bunch of the Python interfaces. Try using QGIS 3.10 or perhaps a bit older. PRs are welcome!
A QGIS plugin for interacting with data from ROS topics and bags.

QGIS can be installed from the QGIS download page. You need to add a PPA if using Ubuntu 16.04.
cd ~/my_ros_ws/src/
git clone [email protected]:locusrobotics/qgis_ros.git
git clone [email protected]:clearpathrobotics/wireless.git
git clone [email protected]:locusrobotics/json_transport.git
catkin build
cd ~/my_ros_ws/src/qgis_ros
pip3 install -r requirements.txtrosrun qgis_ros start_qgis_rosOnce QGIS is loaded, navigate to Plugins -> Installed -> and enable QGIS_ROS with the checkbox. You only need to do this once.
With custom ROS Message Translators:
export QGIS_ROS_EXTRA_TRANSLATORS='custompythonmodule.translators'
rosrun qgis_ros start_qgis_rosIt can often be very tricky to comfortably resolve all dependencies in your workspace because of the combination of ROS1, Python3, GDAL 2, and QGIS.
It uses a lazy/reckless way to expose X server to the container. For alternatives, check out the ROS Docker GUI Tutorial.
cd ~/my_catkin_ws/src/qgis_ros/docker
docker-compose build
xhost +local:root
docker-compose up
xhost -local:root # Remember to remove X server permissions after!
To use extra translators, you'll need to mount a volume with them and/or extend the image.
QGIS is able to read and write data from hundreds of formats and sources by translating these formats into a common in-memory format. In order to represent ROS messages in this format, we target common interchange formats (GeoJSON and GeoTIFF) to make it easy to extend. If you want to make use of a custom ROS message type, all you have to do is:
- subclass
qgis_ros.core.translators.Translator - implement a
translatefunction that accepts a ROS message and returns a GeoJSON-like dict or a path to a GeoTIFF on disk - Add the
VectorTranslatorMixinorRasterTranslatorMixin - Register before launching by setting the envvar
QGIS_ROS_EXTRA_TRANSLATORSto a python module path to an iterable of translators.
Check out the source code for more details.
Only topics that have ROS Message Translators will appear. Not every message has been implemented. If your message is custom, look above for how to create a custom translator. If it is standard to ROS, create an issue or raise a Pull Request with a new one.TODO: add an example to the ROSCon presentation repository and link here. 51
Contributions are appreciated. Please open a pull request.
Developers will notice that camelCase is being used in Python. This may seem unusual, but PyQT and QGIS both use camelCase.So we follow that standard in accordance with PEP8.
