I have a set of X, Y values that indicate some locations in Hong Kong. But I am not able to convert the X/Y into latitude/longitude since the coordinate system is unknown. Is there any way I can fit the X/Y value into many Geographic information systems to find out which system the data provider is using?
The data I have:
X Y
840787 816064
839740 819091
839291 819498
840383 816178
835702 818880
833502 816629
837048 815708
838910 823019
Your coordinates seem to be in EPSG:2326 (Hong Kong 1980 Grid System).
A great way to search for coordinate systems is to go to epsg.io, there you can search registered coordinate systems by country, by code, etc. and get a preview of the coordinates with an interactive map, as well as the definition of the coordinate system.
