Why use the SQL Server 2008 geography data type?
...h coordinate is stored as a double-precision floating-point number that is 64 bits (8 bytes) long, and 8-byte binary value is roughly equivalent to 15 digits of decimal precision, so comparing a decimal(9,6) which is only 5 bytes, isn't exactly a fair comparison. Decimal would have to be a minimum o...
