Raster Resampler

The Raster Resampler tool lets you resample existing rasters to a new resolution while keeping the original projection. It is useful for preparing raster data before training.

Input Raster

Select the raster to resample using the Raster Layer field listing all project rasters

Tip: Make sure the selected raster is correctly imported in the project and not locked by another operation.

Resampling Parameters

Target Resolution: Desired resolution for the output raster (e.g., 0.30 m)

Resampling Method: Interpolation method to apply

  • Nearest
  • Bilinear / Bilinear interpolation (weighted average of the 4 nearest pixels)
  • Cubic / Cubic interpolation (weighted average of the 16 nearest pixels for smoother results)

Tip: Use Nearest for categorical data (e.g., soil classes), Bilinear for continuous values, and Cubic for smoother results on satellite imagery.

Output

Specify the path and name of the resulting raster file

Output File

Commands

  • Run Resampling
  • Cancel

Note: The 'Run Resampling' button executes the process with the selected parameters. 'Cancel' interrupts the operation.

Processing Log

Displays processing information: progress, possible errors, and summary of applied parameters

Tip: Monitor the log to check progress and detect potential errors.

Quick Workflow

  1. Select the raster in Input Raster
  2. Set Target Resolution and Resampling Method
  3. Choose Output File
  4. Click Run Resampling
  5. Check Processing Log for progress
