Expert writing Tips
Best practice
Use "have been mapped" when you want to emphasize that a comprehensive representation or overview of something has been completed, whether physically, genetically, or conceptually.
Common error
While "have been mapped" implies a thorough and detailed representation, using it when only basic information is gathered can be misleading. For instance, saying "the locations of the new stores have been mapped" suggests a comprehensive spatial analysis, whereas "the locations of the new stores have been listed" simply indicates a compilation of addresses.
