Create Image Pyramid

Function Description

Datasets that support creating image pyramids include images, raster datasets, and raster files directly opened as data sources (currently supporting Tiff/GeoTIFF and Erdas Image formats).

Function Entry

  • Start tab->Data Processing group->Image Pyramid.
  • Workspace Manager->Context menu of image (or raster) dataset->Create Image Pyramid.
  • Toolbox->Data Management->Build Pyramids->Build Image Data Pyramids/Build Raster Data Pyramids.

Parameter Description

  • Toolbar Functions:
    • Add Dataset: Open existing datasets in the current workspace.
    • Add File: Select and open single or multiple image files from the local machine.
    • Add Folder: Open all image files in a specified folder, supporting format filtering and recursive reading of subfolders.
    • Select All: Select all image files in the list.
    • Select Reverse: Invert the selection of currently selected and unselected files in the list.
    • Delete: Remove selected image files from the list.
    • Settings: Batch configure the pyramid building method for multiple selected image files.
  • Header Description:
    • Dataset: Name of the dataset for which to create an image pyramid.
    • Datasource: The datasource location where the dataset resides.
    • Image Pyramid: Indicates whether an image pyramid has been created ("Yes" or "No").
    • Width: Number of columns in the image or raster dataset.
    • Height: Number of rows in the image or raster dataset.
    • Resampling Methods: Supports the following Resampling Methods:
      • Nearest: Directly uses the nearest pixel value as the output value.
      • Average: Performs resampling by calculating the average of valid pixel values.
    • Compression Method: Sets the compression format for the output image, currently applicable only to Tiff/GeoTIFF formats. Default is LZW compression. For more methods, refer to Compression Method.
