FAQ: Are raster datasets with non-square cells supported?

Question

Are raster datasets with non-square cells supported?

Answer

ArcGIS is able to read and display raster datasets with non-square cells. This includes the ESRI GRID format as well.

However, in most cases ArcGIS prevents ESRI GRIDs from having non-square cells by default. For example, the Spatial Analyst extension is based on square cell analysis. This means all output data created from Spatial Analyst will have cells that are resampled to square cells.
