@cosmiclibrarian “Ultimately, the early 2026 fireball wave highlights a glaring blind spot in our planetary defense and astronomical monitoring.
Right now, scientists are relying heavily on #crowdsourced eyewitness accounts to calculate #trajectories. When the 7-ton asteroid exploded over Ohio, the only #AMS affiliated #AllskyCamera in the state was offline.”
Loosing Carl, terrible; Loosing his expertise is really bad right now.

Just messing about a bit. Here is the famous #LorenzAttractor plotted using #WxMaxima. The three #trajectories, shown in red, green and blue are for three fairly nearby #InitialConditions.

#MobilityDB is an #opensource data management and analytics platform for #MobilityData (https://github.com/MobilityDB/MobilityDB). Its core function is to efficiently store and query #mobility tracks, such as vehicle #GPS #trajectories. It implements the #OGC #MovingFeatures specification. MobilityDB is engineered from #PostgreSQL and #PostGIS, providing #spatiotemporal #DataManagement via #SQL

"The raw #GPS coordinates and their timestamps were processed to detect individual #trajectories (trips) for each battery using @movingpandas
The individual trajectories were split between stopping points, which were detected when the coordinates of the #batteries remained within a diameter of 200 m for at least 5 min
For each detected trip, the start time, end time, trip duration, trip distance, and average trip speed were determined and recorded for further analysis

🎉 Finally, the first release of #MobilityDB for PostGIS :postgresql: on #windows
#PostGIS 3.3.3 Bundle for #Windows is now available on application
stackbuilder and #OSGeo website.
Details of what's included are listed on:
https://postgis.net/documentation/getting_started/install_windows/released_versions/For more about #MobilityAnalytics in #SQL visit https://mobilitydb.com
Huge thanks to @reginaobe for making this happen

TIL about #ReconTraj4Drones: A Framework for the Reconstruction and #SemanticModeling of #UAV #Trajectories based on #MovingPandas https://www.mdpi.com/2076-3417/13/1/670
Still have to read the paper but it's great to know that @movingpandas is useful for others
