I have a 3 GB database in SQL Server, with certain points stored in float values. The points are stored in EPSG 3765. I would prefer to have them saved in the Geography datatype. I can not store them directly, because the points are stored like this 1734994.3283045683 5740529.6114465743 ( x, y )
Geography requires values between 90 and -90 as well as 180 and -180.
How can I do this? I've been Googling for the last 4 days and can't find a solution. I wouldn't mind writing any code (C#, Python, SQL, etc)
I have no shapefile or anything else, just the data in the DB.
