NetCDF files are projected incorrectly in ArcGIS Pro

Last Published: April 25, 2020


When projecting a Network Common Data Form (NetCDF) file in ArcGIS Pro as a raster layer, the layer is projected incorrectly. For example:

Network Common Data Form (NetCDF) is a file format for storing multidimensional scientific data (variables) such as temperature, humidity, pressure, wind speed, and direction.


This issue occurs because by design, netCDF files are required to be converted to raster layers before they can be used in ArcGIS Pro. For more information, refer to ArcGIS Help: Reading netCDF data as a raster layer.

Solution or Workaround

To convert netCDF files to raster layers, use the Make NetCDF Raster Layer tool located in the Multidimension toolbox in ArcGIS Pro.
  1. In ArcGIS Pro, run the Make NetCDF Raster Layer tool and convert the NetCDF file to a raster layer.
  2. Right-click the layer generated from Step 1 > Data > Export Raster.
  3. Select and define the options and configurations and click OK to run the tool.
  4. Once the NetCDF file is converted, define the Projection. The existing projection defined is inaccurate and must be re-defined. For more information on Projection, refer to ArcGIS Help: Define Projection.
  5. Open the converted file in a new Project and add the basemap. The netCDF data are aligned accurately.
