How big is EPSG 4326 compared to WGS 84?
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.
How to change WGS 84 coordinates in QGIS?
These coordinates in WGS 84 would be something like 12.2/49.8. If, and only if, the layer currently has a wrong CRS assigned to its coordinate values: Right-click on the layer in the Layers list and choose Set Layer CRS. Then pick the appropriate CRS from the list or search with the filter.
Why is my shapefile not in WGS84?
The problem occurs with all shapefiles. Your data seems not to be in WGS84, but in a metric system as you can see from the metadata you posted. The xmin/ymin coordinates 3572722/5453423 have 7 digits both, while coordinates in WGS84 are much smaller (from -180 to 180 degrees).
Is there a visual representation of WGS84 data?
As mentioned above, WGS84 is unprojected — there is no visual representation of that data. So if someone says they want to see their data in WGS84, really they want to see their data in a Plate-Carrée projection, which essentially creates a linear Cartesian graph on the page.
How to reproject shapefile to WGS84 in QGIS?
To reproject your layer then to WGS84, you have to right-click, use Save As and click on Change… behind the current CRS to pick another one and then press OK to create a new copy of your data with that new CRS.
Is there a WGS84 / itrfxx transformation in ArcGIS?
WGS84/ITRFxx are about 1 m from NAD83 2011. If you don’t want the transformation, set it to none, or use 6318 (NAD 1983 (2011)) as the input GCS rather than WGS84. We don’t have a WGS84/NAD83(2011) transformation that has its parameters set to zeroes.
What’s the difference between QGIS and ArcMap file size?
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.
