Micah, Thanks for those references. Here is my situation. I have some software that reads a SHP file. I understand the spec has changed with regards to locations. In particular, I believe the level of precision in LAT, LON data has changed. Further, the change is with respect to this particular format (example for LAT): NDDMMSS.SSS I have gone to the two web sites you referenced below and have been looking through the available data and so far all the data is in decimal degrees, which doesn’t help. Thanks again, …Dennis
