We have created a site based on Canonn data. It only uses the data from the Canonn spreadsheet that has been verified. It is still under development so we have not listed it on our main site yet, it is here: http://elitedangerous.hozbase.co.uk/customtable/view/barnacles
It links to EDDB for system information and the HotDoy website for help with creating bearings from latitude and longtitudes. Look for the columns that show the MA as being ripe. It can also list them in order of proximity to a system that you specify.
