2.    Output Raster Dataset

The name, location, and format for the dataset you are creating.

When storing a raster dataset in a geodatabase, do not add a file extension to the name of the raster dataset. When storing your raster dataset to a JPEG file, a JPEG 2000 file, a TIFF file, or a geodatabase, you can specify a compression type and compression quality.

3.    Output Cell Size (optional)

The cell size of the new raster using an existing raster dataset or specify its width (x) and height (y).

4.    Resampling Technique (optional)

Choose an appropriate technique based on the type of data you have.

  1. NEAREST— Nearest neighbor is the fastest resampling method; it minimizes changes to pixel values since no new values are created. It is suitable for discrete data, such as land cover.
  2. BILINEAR— Bilinear interpolation calculates the value of each pixel by averaging (weighted for distance) the values of the surrounding four pixels. It is suitable for continuous data.
  3. CUBIC— Cubic convolution calculates the value of each pixel by fitting a smooth curve based on the surrounding 16 pixels. This produces the smoothest image but can create values outside of the range found in the source data. It is suitable for continuous data.
  4. MAJORITY—Majority resampling determines the value of each pixel based on the most popular value in a 3 by 3 window. Suitable for discrete data.
