Arc Desktop 10.5.1
I am converting an Arc Grid raster to a tif using the Raster To Other Format (multiple) tool.
In the tool's Environments... settings, I am snapping the output tif to a different tif raster.
All rasters involved have identical cell sizes (three feet), and all have the same horizontal and vertical CRS/projections.
The Environments... help implies that only an x/y shift occurs with raster snapping, without any sort of transformation (such as in a reprojection).
However, the Environments... help also states, within the Raster Storage section:
“Resampling is the process of interpolating the pixel values while transforming your raster dataset. This is used when the input and output do not line up exactly, when the pixel size changes, when the data is shifted, or a combination of these.” My emphasis.
My understanding has long been that a snap by itself would not invoke a transform (and thus resampling). But after a closer look at the above help (IMHO ambiguous) I'm not so sure! I need to know if it does so that I can then decide what resampling technique I want to use, so I'm asking for assistance: does a raster snap involve transforming, and thus resampling?
