Create an Image Pyramid
Feature Description
Datasets that support creating an image pyramid include image datasets, raster datasets, and raster files opened directly as datasources (currently supporting Tiff/GeoTIFF and Erdas Image formats).
Function Entrances
- Start tab->Data Processing group->Image Pyramid.
- Workspace Manager->Context menu of an image (or raster) dataset->Create an Image Pyramid.
- Toolbox->Data Management->Build Pyramids->Create Pyramid of Image Data/Create a Raster Data Pyramid.
- Imagery tab->General Data Processing group->Image Pyramid.
Parameter Description
- Toolbar Functions:
- Add Dataset: Opens existing datasets in the current workspace.
- Add File: Selects and opens one or multiple image files from local storage.
- Add Folder: Opens all image files within a specified folder, supporting filtering by format and recursively reading subfolders.
- Select All: Selects all image files in the list.
- Select Reverse: Inversely selects the currently selected and unselected files in the list.
- Delete: Removes the selected image files from the list.
- Settings: Sets the pyramid building way in batch for multiple selected image files.
- Table Header Description:
- Dataset: The name of the dataset for which to create an image pyramid.
- Datasource: The location of the datasource containing the dataset.
- Image Pyramid: Indicates whether an image pyramid has been created ("Yes" or "No").
- Width: The number of columns in the image or raster dataset.
- Height: The number of rows in the image or raster dataset.
- Resampling Methods: Supports the following Resampling Method:
- 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, defaulting to LZW compression. For more method introductions, please refer to Compression Method.
