Elite: Dangerous Astrometrics is a website devoted to providing maps, graphs, charts, and data extracted from the Elite: Dangerous game, via player submissions to EDSM.net and the EDDN network, via programs such as ED-Discovery.
It started out as an experiment, downloading the EDSM data dumps and building a local copy of the database, and then attempting to make some visualizations. This rapidly grew into a wide range of maps and graphs.
The name "Astrometrics" is intended in the Star Trek: Voyager sense of the term, relating to cartography and visualizations, as well as data and analysis, rather than the real world "Astrometry" which refers to precision measurements of stellar objects and their relative positions in the sky.
