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.
