So I work in aviation and the big buzz over the last years (practically the last decade) is something called AIXM or Aeronautical Information Exchange Model, basically its a standardized format so that data can be exchanged (free??) between different aviation sectors. It is based on XML and GML and very complex in nature. On the AIXM forum a question was asked how to get data into a geodatabase, weirdly enough it was by someone working for ESRI so that sparked my curiosity when he said their own solution isn’t enough.
I have in several occasions viewed AIXM data inside QGIS, so I decided to do a video on a possible way of getting AIXM data into a GIS system, since the question was specifically how to get to an ESRI geodatabase, the video shows that extra step, but once in QGIS you could as easily decide to get the data within spatialite, postgis, etc and even connected to geoserver have a WMS or WFS server for it
Here is the video with some sample data from the AIXM wiki
