Arc GIS Pro Raster Extraction

[Anish]

I am encountering an issue with ArcGIS Pro when performing raster operations, specifically the Creating Slope Map from DEM and Export Raster tools. After extraction, the output raster's cell size and rows/columns seem to change, even though I have not altered the input data. Here is a summary of the problem:

Problem Details:

• Before Extraction:

  • Raster Dimensions: 4348 Columns x 2335 Rows

  • Cell Size: 31.09 x 32.72

  • Raster Format: TIFF

  • Pixel Type: Floating Point

• After Extraction:

  • Raster Dimensions: 4349 Columns x 2336 Rows (slight increase in size)

  • Cell Size: 32.05 x 32.72 

  • Compression: None

I have tried setting the Snap Raster and Extent to match the original raster, but the issue persists. I would appreciate any advice or steps to ensure that the output raster matches the input raster exactly in terms of cell size, rows/columns, and alignment.

There is option to SET the output cell sizes vs. letting it default. Notice 1 row and column was added, most likely the projection being used has rotation causing these to be added.
