Hello Everyone, I was wondering if anyone could tell me how sea-level is zeroed in the 2' contour layers on the Maine GIS site? Is it from low tide, high tide, or mean tide level? Thanks in advance, and I apologize in advance if this answer is obvious. I didn't see it in the metadata. Thanks,Aaron Aaron Gilbreath 148 East Main StYarmouth, ME 04096(207) 841-4805 ----------------------------------------------------------------------- This list Maine GeoNews (GEOLIBRARY-L) is an unmoderated discussion list for all Maine GIS Users.
