>    Considering the caveats in the attached doc (i.e., we follow US govt. policies; certainly anyone else using this data set can change it to conform to their own policies), we always welcome from professional geographers like yourselves  any corrections, suggestions, questions on international land (not maritime!) boundaries, their history, alignments, lengths, etc.
