+
+I used extensively postgis (+ecosystem) for my phd thesis, in several ways.
+The first is that PostGIS is a good steady horse (elephant?):
+a database is the perfect place to store a lot of very different information in the same place and put them in relation.
+For geospatial data, postgis means you always have a way to put data in relation (are they at the same place?).
+
+<!-- pagebreak -->
+
+1. So we have a vehicle with lots of sensors (camera, lidar, gps, etc.)
+Postgis is the perfect candidate to store metadata of all of this.
+For instance I would store the image position, the lidar points using pgpointcloud, the trajectory, the metadata,etc.
+Postgis advanced linear referencing capabilities means its possible to deal with the temporal aspect of the data as well.
+
+2. Second usage is PostGIS ecosystem.
+Postgis has a strong ecosystem, and that alone is a very good reason to use it. This ecosystem is even wider because so many tools can read/write into PostGIS.
+I mentionned pgpointcloud, but postgis_topology is the base of my work, and I also used pgrounting to perform graph analysis and road network reconstruction, and postgis raster to store and use some aerial images, as well as postgres extension (text analysis).
+
+3. Third usage : power user
+Now for the advanced part, postgis is so reliable and flexible it can be abused to perform all sort of nice things, especially in the field of automatism.
+In my phd I perform road generation for Paris fully in base, with a lot of call to postgis geometrical functions.
+
+Furthermore, PostGIS + trigger + any GIS can be made into [potent interactive system](https://www.youtube.com/watch?v=grlkUvvSf3w&t=5m36s)
+, and because of the whole transaction stuff, multi user [is facilitated](http://remi-c.github.io/interactive_map_tracking/).
