Probably a real simple question but wonder if someone can straighten me out. I got some data in Arcview SHP files in which they told me the projection is a Geographic Projection or Lat/Long (No projection). Now my question is even if the data is in Lat/Long geographic coordinates does it not need to be associated with a datum like Nad83 or something else? If lat/long coordinates can have no datum associated do I import it in MapInfo using the first Lat/Long projection system listed (which doesn't seem to indicate a datum)? I also have a lot of MapInfo data that is in this first lat/long (no datum indicated) projection system, does that mean all this data has no datum? I've heard that if data is in this first Lat/Long projection system listed in MapInfo and then later decide to do a "save copy as" to convert it to Nad83 for example, that MapInfo doesn't convert it to Nad83 it just associates your data as being Nad83 now and no coordinates have been converted, is that true? Can anyone clear this up for me.
