Hey Zuur, great resource so far! I know the SC universe is still in its infancy, but here are a couple maps from other games that could give you ideas of how mature worlds have been mapped; and perhaps you can build your mapping system to be as powerful. X3 (one of my favorite games) has this great map which has information on each star system: http://eng.x3tc.ru/x3_tc_map/ More cooler interactive map from GuildWar which shows terrain and resources : http://gw2cartographers.com/ I think for either you will need a SQL (MySQL, choose your poison) to house the massive amounts of data. Your web interface building knowledge is great, mine is not so much. However, if you need help with the database portion to normalize tables and such, I can help you. I see there can be different interfaces for inputting data by our Exploration team and anyone else. Maybe only exploration can add/delete/modify, everyone else in guild can add/flag something as old, etc. If we do put a lot of time into this, I definitely think it needs to be a secured site that is internal only. Again, PM me if you need help trying to take this to the next level.
