coordinate system - ArcGIS: Goode Homolosine Projection and Inconsistent Extents

I recently posted about a problem in ArcGIS using the Goode Homolosine (Land) projection with the Project Raster tool HERE.

The problem was related to a bug with that tool, and a workaround solution was proposed.

I have since tried to re-project different data to the Goode Homolosine projection, but the workaround solution does not work for these data. I find the proposed solution to work for some data but not others.

Here is an example of the proposed solution that produces an Inconsistent Extent warning:

1. I downloaded this Crop Suitability Index raster data.


2. I open these data in ArcMap and set the data frame's coordinate system to projected coordinate systems, world, Goode's Homolosine (Land).


3. In the table of contents I right click the data and select Data, Export Data.


4. When exporting I set the Spatial Reference to the Data Frame, and save as a .tif file.


5. When I open the saved .tif file in a blank map I receive an Inconsistent Extent warning message.

I do not understand why this workaround solution isn't a general solution, i.e., why this solution worked with the Malaria Ecology Index raster data I originally posted about, but not these Crop Suitability Index raster data?

Answer

Well, we won't know for sure until a developer debugs the tool to figure out what's happening.

In the earlier dataset, the Malaria Ecology Index, the version that triggered the warning had one extra row and column of cells, so it could be a slightly different rounding algorithm when the projected raster's extent is calculated.

Without looking at the new dataset, it may have two columns or rows, enough that export data tool in ArcMap still has a row or column extra and the output triggers the warning.

Please note that the warning is just that--a warning. It shouldn't affect display or most work.
