I am looking for a couple very basic polygon shapefiles. One with oceans (specifically the Atlantic Ocean) and one that has the St. Lawrence Seaway/River. The projection is not so important (I can always adjust those to meet my needs later). Does anybody have a good source for these?
I thought those real basic types of shapefiles used to be included in the ESRI software but either it isn't anymore or we just don't have it in our office.
