1. A method for communicating area information in a common framework, comprising the steps of: providing a first set of instructions which generates an area of interest (AOI) defined by a first geometric shape; defining the first geometric shape by one or more coordinates; converting the one or more coordinates to a second set of coordinates for use with a second set of instructions different than the first set of instructions, wherein the second set of coordinates is defined by a new AOI which includes information associated with the first set of instructions and which is interpreted by the second set of instructions.
