[Incubator] MobilityDB

[Mahmoud SAKR]

Dear Incubation Committee,
We would like to introduce our Open Source project "MobilityDB", hoping to
identify the next steps that we can take to include it as an OSGeo
community project.

MobilityDB is a database management system for moving object geospatial
trajectories, such as GPS traces. It extends PostgreSQL and PostGIS by
temporal and spatiotemporal types and operations. The goal of MobilityDB is
to provide users with the database support to seamlessly store mobility
tracks, and query them in SQL.

MobilityDB provides two main geospatial trajectory types: tgeompoint for a
temporal geometry point, and tgeogpoint for a temporal geography point.
Both can represent a geospatial point that moves over time, where the
coordinates are respectively expressed as PostGIS geometry or geography. It
also provides spatiotemporal indexes and a rich set of functions to manage
these types; including: input/output, topological relationships, speed,
direction, distance, etc. Note that the return values of many of these
functions are temporal. For example, the speed of a car is a value that
changes over time. Therefore the type system of MobilityDB includes types
for temporal floats, temporal Booleans, temporal text, and temporal
integers.

The work in MobilityDB has been presented in multiple scientific
publications and in multiple community conferences including PGConf.Russia
2019 and 2020, FOSDEM PGDay 2020, FOSDEM GeoSpatial Devroom 2020, and
FOSS4G Belgium 2019. Some of these presentation can be found here:

https://fosdem.org/2020/schedule/event/mobilitydb/
https://docs.mobilitydb.com/pub/MobilityDB_FOSS4G_Brussels_2019.pdf

To prepare this request, we went through Jody's presentation, and the Wiki
shared in Vicky's message. Our github repository has been evolved to meet
the checklist (geospatial, opensource, participatory). In particular,
MobilityDB solves a geospatial problem, is distributed under the PostgreSQL
license, and it is open for contributions (with currently 6 contributors
from different organizations). It also has a steering committee with a
focus on achieving good integration with relevant projects in the OSGeo
family:

Besides the main repository, and thanks to all contributors, other
repositories are being actively maintained in our GitHub organisation:
- python connectivity driver (
https://github.com/MobilityDB/MobilityDB-python)
- Data generator of simulated car trajectories (
https://github.com/MobilityDB/MobilityDB-BerlinMOD)
- Multiple workshop tutorials (
https://github.com/MobilityDB/MobilityDB-workshop)
- MobilityDB docker images (https://github.com/MobilityDB/MobilityDB-docker)

The main github repository ()

The github organization

User manual for the last release (now beta1):
https://docs.mobilitydb.com/MobilityDB/master/
The manual in develop branch is continuously updated with the most recent
development. Developers can then build

We are happy to receive your support, and to respond to your questions and
comments.

Best regards,
Mahmoud SAKR, PhD
Research Associate
