Since everyone is doing this, here is my Google Scholar wordcloud. Pretty spot on, but slighltly skewed by one collaborator's work 🤣.

Congratulations to the MobilityDB team on the joint release candidate 1.1 of #MobilityDB, #MEOS, and #PyMEOS 🎉

➡️ https://github.com/MobilityDB/MobilityDB/releases/tag/v1.1.0rc1
➡️ https://github.com/MobilityDB/PyMEOS/releases/tag/pymeos-1.1.3rc1

The most important change in v1.1 was to extract the core functionality for temporal and #spatiotemporal #DataManagement from MobilityDB into the #Mobility Engine #OpenSource (MEOS) C library. https://libmeos.org/

In this way, the same functionality provided by MobilityDB in a database environment is available in a C (...)

Finding Geospatial Accounts on Mastodon

Besides following hashtags, such as #GISChat, #QGIS, #FOSS4G, and #OSGeo, curating good lists is probably the best way to stay up to date with geospatial developments. To get you started (or to potentially enrich your existing lists), I thought I'd share my #Geospatial and #SpatialDataScience lists with you.

If you liked our last year's short paper on #DeepLearning from #TrajectoryData, you'll love our new #preprint even more:

Hi @kimaidou, do you know, does #Lizmap support identify results / popups for raster layers?

I checked out the demos (https://demo.lizmap.com/lizmap/) but couldn't find any with raster example to answer my question.

Thanks.

Hi @felt, I'm trying out your custom basemap option and have run into issues when trying to use the Austrian basemap.at service. I copied the URL over from #QGIS where it works as expected:

Do you have any pointers for me?

The #QGIS #Trajectools toolbox continues to grow.

New in: stop detection and trajectory styling

I’m continuously testing the algorithms integrated so far to see if they work as GIS users would expect and can to ensure that they can be integrated in Processing model seamlessly.

I hope us LinkedIn user will get some monetary value back from those collaborative articles content which will obviously go into training some premium Gen-AI Chatbot to compete with Microsoft/Google/Meta, but be a gazzillion times worse because it's LinkedIn.

Seriously, don't donate your time and expertise, for free, to a for-profit

Today, we've had our first successful #Trajectools mini workshop with colleagues from the EMERALDS project, working on #PublicTransport #TrajectoryAnalysis

If everything goes to plan, Trajectools will be at #MDM2024
@mdm

There are still a few days left to submit your own work and join us: https://mdm2024.github.io/calls.html

Today is National Compliment Day! For today's #gischat, share the highest compliment you think could give to a cartographer/GIS professional.

I'll go first: "You make labeling 367 points look easy!"

It's time for #GISchat 🌐🗨️ ! What mappy things you're working on this week?

We could easily spend years talking about all the possible problems with data, but that's not helpful when you have a dataset in front of you here and now. So what are some questions you can ask about quantitative data to figure out whether you can trust it?

#Trajectools development version now features out-of-the-box Interpolated Line styling for trajectories 🌈

Additionally, we can now clip a trajectory layer by a polygon layer (as well as to an extent)

Looking for a tool to compare #GTFS time tables and actual realtime GTFS / PT tracks to analyze #PublicTransport punctuality. Any pointers? Sounds like something that should already exist.
