1. A method, comprising:
receiving a metrology report including metrology data collected by a metrology tool, position data associated with the metrology data, and context data associated with the metrology tool and identifying a type of metrology process employed by the metrology tool;
determining a first coordinate system employed by the metrology tool based on the context data by accessing a database storing a plurality of coordinate systems indexed by the type of metrology process;
transforming the position data from the first coordinate system to a second coordinate system to generate transformed position data; and
storing the transformed position data and the metrology data in a data store and associating the transformed position data with the metrology data.
