I am projecting a shapefile from "NAD 1983 2011 StatePlane New Hampshire FIPS 2800 Ft US" to "EPSG 4326, WGS 84." However, the result output by QGIS seems to differ by about 3.25 feet from the ArcMap output. The QGIS shapefile is also about 20% smaller in file size. I tried the same function in FME and it matches the QGIS output spatially, but has the same file size as the ArcMap output. I tried in Global Mapper and the output is about .001 feet North of what I get with QGIS and FME
Why don't these match up?
