I am trying to create a random sampling map of an ocean area. To do this, I would like to create cells that are 1' x 1' in size (one minute by one minute in DMS). My map is using WGS 1984 Web Mercator as the coordinate system. Whenever I go into the Fishnet tool, it asks for cell size, but this appears to be in meters.
One minute of latitude is supposedly 6,068 feet (1.15 miles) which is about 1849.526 m and one minute of longitude is 4,800 feet or about 1463.04 m.
The issue is that this projects a straight solid grid onto the map, which when I compare it to a graticule in the layout divided into 1' ticks, these boxes do not line up. I am completely okay with having not perfectly straight boxes as I am working with a large area and am expecting curvature.
The graticule would be fine to use as a grid system but I will later be stratifying the map and need to export cell data, which is why I am trying to use Fishnet.
