I am trying to convert a polygon to raster and I noticed that the cell size of the resulting raster appears different for different coordinate systems, despite me setting the cell size the same. Both coordinate systems are in meters. Here's what I mean:
To begin, I set the polygon to raster cell size as 28 meters.
I run the tool with projected coordinate system of "WGS 1984 Web Mercator (auxiliary sphere)" and the resulting cell size is about 20.8 meters:
What's even weirder is that when I check the properties of that layer, it still says that the cell size is 28 and that the units are meters:
Now if I run the polygon to raster tool with the projected coordinate system of "NAD 1983 UTM Zone 16N", the cell size is as I expect, 28 meters.
Can anyone explain why the resulting cell sizes are different?
