Deep learning from trajectory data

I’ve previously written about Movement data in GIS and the AI hype and today’s post is a follow-up in which I want to share with you a new review of the state of the art in deep learning from trajectory data.

Our review covers 8 use cases:

  1. Location classification
  2. Arrival time prediction
  3. Traffic flow / activity prediction
  4. Trajectory prediction
  5. Trajectory classification
  6. Next location prediction
  7. Anomaly detection
  8. Synthetic data generation

We particularly looked into the trajectory data preprocessing steps and the specific movement data representation used as input to train the neutral networks:

On a completely subjective note: the price for most surprising approach goes to natural language processing (NLP) Transfomers for traffic volume prediction.

The paper was presented at BMDA2023 and you can watch the full talk recording here:

QGIS Cloud: Publish Live Data in Web Map

The QGIS Cloud Support Team is often asked if it is possible to integrate data from external databases into the QGIS Cloud Web Map, so that the map information in the QGIS Cloud Web Map is always up-to-date. In this blog article we would like to show how this is possible with PostgreSQL. To publish data in the QGIS Cloud GDI, the data must always be stored in the personal QGIS Cloud database.

Reports from the winning grant proposals 2022

With the QGIS Grant Programme 2022, we were able to support four proposals that are aimed to improve the QGIS project, including software, infrastructure, and documentation. The following reports summarize the work performed in the proposals. 

  1. Support building QGIS application on Qt 6 (#243) – Report
    In addition to the original plan of porting the “gui” and “app” libraries to Qt 6, it was possible to complete also the “3d” and “server” libraries. We now are at a stage where the majority of QGIS builds and runs without any significant issues on Qt 6. The Github CI setup has been updated to also run the C++ tests for gui, app, server and 3d, and the majority of these have been fixed so that they pass on the Qt 6 builds too. In addition, some tests which were failing under Qt 6 revealed some real QGIS bugs which have been fixed in the process of this work. (So there’s a direct benefit for the existing Qt 5 builds too!).
  2. Add SQL Logging in the debugging/development panel (#242) – Report
    When debugging or developing a QGIS algorithm or a QGIS plugin and when investigating performances of a particular layer it is often useful to view the SQL commands that QGIS sends to the backend. The SQL logging was implemented for Postgres, GeoPackage, Spatialite and Oracle data providers. immagine
  3. QGIS setting registry follow-up (#245) – Report
    The work can mainly be seen here PR qgis/QGIS#51295 with the proposed approach to register settings in a hierarchical and organized way, without too much complexity in the API to actually use the settings.
    To have a clean approach, some keys have been renamed. There is a compatibility handling (both forward and backward). The GUI implementation will be worked on during the HF in NL this spring.
  4. Fix handling of provider default value clauses/Autogenerate/nextval(…) handling (#247) – Report
    The bulk of these changes landed in the QGIS 3.28 release. A quick way to demonstrate on of the issues fixed is: open a Geopackage file, start editing the layer, add some features to it, but don’t save the edits, then right click the edited layer and try to save it to a different file. On older QGIS releases you’ll be spammed with a number of error messages because we tried to write a string value of “Autogenerate” into a number field for all the newly created features. On QGIS 3.28 this all just works as expected, with no errors encountered.

Thank you to everyone who participated and made this round of grants a great success and thank you to all our sustaining members and donors who make this initiative possible!

Global map shading

Map data without global terrain shading

Global terrain shading for point clouds, dem and vectors

To see this feature in action, you can open QGIS project properties and under Terrain, there should be an option for Global Map Shading. You will need to first add a raster as your DEM under the Terrain section.

Elevations of all these layers are combined and the considered elevation is chosen depending on one of two methods:

  1. the highest elevation between raster, mesh or point cloud layers will be selected.
  2. elevation will be selected based on the order of layers in the layer panel.

Depending on the context and the use of the map the user can choose the more appropriate method.

For now, the shading methods implemented are the Eye Dome Lighting and the hill-shade. More methods could be added in the future - such as ambient occlusion.

The user can choose the elevation shading settings in a specific UI widget that can be found in two places:

  1. under the Project Properties, within the same tab of the project elevation settings.
  2. under the Styling Panel, a new tab is added for quick access to the user.

Profile elevation within print composer

This work was carried out by our collaborator North Road. The profile tool can embed elevation profiles within print layouts. It is possible to add beautifully styled profiles in your print outputs.

Embeding elevation profile in the print composer

To use elevation profiles in print layouts, simply click the Add Elevation Profile button icon elevation profile in print composer in the toolbar, and then to initialize it, copy profile configuration from an existing elevation profile from QGIS main window using the “Copy From Profile” button.

3D navigation improvements

With the new improvements, you can:

  1. move camera vertically using ctrl+shift+left mouse button
  2. keep zooming with the wheel while moving the mouse
  3. continue right mouse button zooming when pointer exits the viewport

Improve zoom-extents in 3D

The terrain’s and point cloud layers’ elevation range are taken into account so that the camera is not positioned below the scene’s contents, which was the case when using the terrain’s vertical scale setting to exaggerate the elevation differences.

Limit 3D scenes’ 2D extent

3D Views can now be limited to a specific 2D extent. The terrain is clipped and no 3D features beyond that extent are loaded, making it easy to render specific areas of big QGIS projects. The project’s 2D extent is used by default which can then be adjusted in each 3D view separately using the new General tab in 3D configuration.

Limiting 3D map extent

Future updates

There will be more features planned for QGIS 3.32. We are finalising the Processing framework for point cloud data and it should be available on QGIS master in coming weeks.

Please do not hesitate to contact us if you have any suggestions to improve QGIS 3D and point cloud support.

How Oslandia invests in OpenSource

You may be wondering where Oslandia’s name is coming from ? Or maybe you already know ? In this article we focus on the “OS” part of Oslandia : OpenSource !

Oslandia positions itself as IT expert in the field of OpenSource geographical information systems. QGIS is namely one of the proheminent opensource softwares for the geospatial industry. This position is a key element of our business model.

But do you know how we work behind the scene ? This article will give you an opportunity to discover some of our contributions to the OpenSource ecosystem.


Our general business model is based on projects we carry out for our clients. They fund us to design and implement solutions adapted to their needs and requirements. Part of these developments consist in core development of Opensource software. This allows us to contribute actively to FOSS4G components.

But this funding method makes it complicated to fund maintenance, or new exploratory developments, as well as communication, community management or other tasks necessary for healthy opensource projects.

As a consequence, we introduced at Oslandia a mechanism of internal OpenSource project grants.

These grants constitute self-investment from the company into the OpenSource ecosystem, and can be applied to new projects, research and development or existing projects.

This mechanism has multiple interests :

  • For opensource projects : maintenance and new contributions
  • For Oslandia : image and potential new business opportunities
  • For the team : work on projects that matter to them

These OpenSource grants consist in a large range of possible tasks, as we often say : “Opensource projects are not only code”. Instead of developers, we prefer the term contributors. Development, code review, maintenance, documentation, community management, communication, each collaborator can choose the type of task to focus on.

We differentiate software maintenance grants and opensource project grants. We call the latter “OpenSource mini-projects

Software maintenance consists in refactoring, bugfixing, packaging, release management… All these tasks need dedicated time which is difficult to fund directly on client’s project.

Opensource mini-projects grants are specific opensource proposal which can be submitted by any collaborator on any subject. We then vote on the best proposal and the team can start working on the subject within the allocated budget.

Some numbers

We allocate around 5% of the global production time to software maintenance grants. Our Opensource maintenance grant for 2022 is therefore approximately 190 days of work. It mainly focus on QGIS, PostGIS, QWC2, Giro3D and a few other components we actively maintain.

We also allocate 5% of the global production time to opensource mini-projects grants. It represents an additional 190 days of work for 2022.

Oslandia therefore invests almost 400 days of work into the OpenSource ecosystem, outside of direct contributions for client’s projects.

Opensource Mini-projects

OpenSource mini-projects grants are submitted by Oslandia’s collaborators and focus on various task and thematics : innovation, development, design, prototyping, communication or any other kind of Opensource contribution.

Proposals have to define goals, deliverables, planning, team and needed budget. Then we evaluate the proposals given the following criteria :

  • proposal coherency ( e.g. deliverables vs budget )
  • alignment with Oslandia’s strategy
  • innovation level
  • business opportunities
  • fun and motivation
  • impacts in terms of communication
  • links with other projects at Oslandia
  • possibility of extra R&D funding

We then vote on best proposal and manage these mini-projects just as a client project.



The maintenance grant on QGIS allowed us to work on the following tasks :

  • Bugfixing
  • Code review for PRs submitted by other developers
  • Code refactoring
  • Documentation
  • Packaging pipeline
  • OSGeo4W improvement

OpenSource mini-projects grants

During the year of 2022, we worked on the following mini-projects :

In 2023 we will continue to work on these projects, and others ! for example pg_featureserv, py3dtiles, infoclimat website, MapProxypgRouting


This investment mechanism allows Oslandia to be an opensource “pure player” and contribute actively to these OpenSource projects and to the OpenSource ecosystem as a whole.

Should you be interested in our contribution model, or if you have any question regarding our internal OpenSource grant program, do not hesitate to contact us : [email protected] !

Tracking geoprocessing workflows with QGIS & DVC

Today’s post is a geeky deep dive into how to leverage DVC (not just) data version control to track QGIS geoprocessing workflows.

“Why is this great?” you may ask.

DVC tracks data, parameters, and code. If anything changes, we simply rerun the process and DVC will figure out which stages need to be recomputed and which can be skipped by re-using cached results.

This can lead to huge time savings compared to re-running the whole model

You can find the source code used in this post on my repo

I’m using DVC with the DVC plugin for VSCode but DVC can be used completely from the command line, if you prefer this appraoch.

Basically, what follows is a proof of concept: converting a QGIS Processing model to a DVC workflow. In the following screenshot, you can see the main stages

  1. The QGIS model in the upper left corner
  2. The Python script exported from the QGIS model builder in the lower left corner
  3. The DVC stages in my dvc.yaml file in the upper right corner (And please ignore the hello world stage. It’s a left over from my first experiment)
  4. The DVC DAG visualizing the sequence of stages. Looks similar to the QGIS model, doesn’t it ;-)

Besides the stage definitions in dvc.yaml, there’s a parameters file:

  n: 10
  size: 0.5

And, of course, the two stages, each as it’s own Python script.

First, which reads the random-points.n parameter to create the desired number of points within the polygon defined in qgis3/data/test.geojson:

import dvc.api

from qgis.core import QgsVectorLayer
from processing.core.Processing import Processing
import processing


params = dvc.api.params_show()
pts_n = params['random-points']['n']

input_vector = QgsVectorLayer("qgis3/data/test.geojson")
output_filename = "qgis3/output/random-points.geojson"

alg_params = {
    'INPUT': input_vector,
    'MIN_DISTANCE': 0,
    'POINTS_NUMBER': pts_n,
    'SEED': None,
    'OUTPUT': output_filename
}'native:randompointsinpolygons', alg_params)

And second, which reads the buffer-points.size parameter to buffer the previously generated points:

import dvc.api
import geopandas as gpd
import matplotlib.pyplot as plt

from qgis.core import QgsVectorLayer
from processing.core.Processing import Processing
import processing


params = dvc.api.params_show()
buffer_size = params['buffer-points']['size']

input_vector = QgsVectorLayer("qgis3/output/random-points.geojson")
output_filename = "qgis3/output/buffered-points.geojson"

alg_params = {
    'DISSOLVE': False,
    'DISTANCE': buffer_size,
    'END_CAP_STYLE': 0,  # Round
    'INPUT': input_vector,
    'JOIN_STYLE': 0,  # Round
    'MITER_LIMIT': 2,
    'SEGMENTS': 5,
    'OUTPUT': output_filename
}'native:buffer', alg_params)

gdf = gpd.read_file(output_filename)


With these things in place, we can use dvc to run the workflow, either from within VSCode or from the command line. Here, you can see the workflow (and how dvc skips stages and fetches results from cache) in action:

If you try it out yourself, let me know what you think.

QField 2.6: perfecting high-accuracy positioning

It’s only been a few weeks into the new year, but we’ve got great news for you: a brand new QField 2.6 “Geeky Gecko 🦎” has been released with a focus on positioning improvements, including Bluetooth support for Windows. And with that, we are delighted to remove the ‘beta’ status from QField for Windows.

New positioning features

Let’s open with a bang: QField 2.6 now supports NMEA streaming from external GNSS devices over TCP, UDP, and serial ports, in addition to preexisting Bluetooth connectivity. This new functionality means that QField is now compatible with a much larger range of GNSS devices out there.

These new receivers unlock NTRIP-driven centimetre accuracy for devices that use the Bluetooth connection to a manufacturer’s application to connect to NTRIP servers. In this scenario, QField could not initiate a Bluetooth connection since it was already taken. With the new TCP and UDP receivers – provided the manufacturer’s application offers NMEA streaming over either of those Internet protocols – QField can connect and consume high-accuracy positioning.

The presence of a serial port receiver provides support for external GNSS devices using Bluetooth on Windows via the virtual serial port created by the operating system. The lack of Bluetooth support on Windows was a long-wanted enhancement from QField users on that platform and was the last blocker for the ‘beta’ status to go away.

In addition, QField 2.6 allows users to pick from half a dozen metrics a value to attach to the measure (M) dimension of geometries being digitized when locked to the current position. This functionality is available to both users digitizing and the positioning tracker. The measurement values available as of 2.6 are timestamp, ground speed, bearing, horizontal accuracy and vertical accuracy, as well as PDOP, HDOP and VDOP values.

Growing Continuous Integration (CI) testing framework now covers positioning

Starting with version 2.6, QField ships with increased quality assurances thanks to the addition of tests covering positioning functionalities in its growing CI framework.

Practically speaking, this means that every single line of QField code changed is now being tested against positioning-related regression, significantly decreasing the risks of shipping a new version of QField with broken functionality in the area of antenna height, vertical grid shift, and ellipsoidal height adjustments.

We would like to commend Deutsche Bahn for funding the required work here. This could not have come in soon enough as more and more people are opting for QField and relying on it for their crucial day-to-day fieldwork.
