Specifies whether to output images from different locations according to their respective zonal coordinate systems. By default, it is unchecked, meaning a unified coordinate system is used for output.

• Checked: You need to set the projection type, zoning method, and Add Zone Number parameters. The program will automatically calculate the corresponding projected coordinate system based on these three parameters and the image locations, and output images from different locations according to their respective zonal coordinate systems.
• Unchecked: You need to set the output coordinate system parameters. All images will be output using this unified coordinate system.

Will be automatically applied to all processes and result data in the workflow production.

Note:

Only useful when executing the complete flow. If only a specific tool within the flow is executed, the output result data may not use the coordinate system set here.

Available after the Zonal Output parameter is checked.

Provides two projection types: Universal Transverse Mercator (WGS 1984) and Gauss-Kruger (CGCS 2000). Default is Gauss-Kruger (CGCS 2000).

Available after the Zonal Output parameter is checked.

Specifies the zoning projection method as Six-Degree Zone or Three-Degree Zone. Default is Six-Degree Zone.

Available after the Zonal Output parameter is checked.

Specifies whether to include the zone number in the projected coordinate system. When checked, the output projected coordinate system will include the zone number; when unchecked, it will not.

Available after the Zonal Output parameter is unchecked.

Sets the coordinate system for the imagery. Intermediate and result data will be output using this coordinate system.

Sets the storage type for result images. Provides four options: Unspecified, Tiff/GeoTIFF, Erdas Image, and PCIDSK. Default is Tiff/GeoTIFF, which means using the original storage type of the image for output.

Will be automatically applied to all processes and result data in the workflow production.

Only available when Output Format is Tiff/GeoTIFF. Default is NONE. For more method introductions, please refer to Compression Method.

Will be automatically applied to all processes and result data in the workflow production.

Plane accuracy determines whether to perform rough correction on the original image. Default is High, meaning no rough correction is performed on the image. Selecting Medium or Low will perform rough correction on the original image.

• Low: Generally indicates image planar accuracy error is greater than 40 pixels.
• High: Generally indicates image planar accuracy error is less than 15 pixels.
• Medium: When unable to determine image accuracy, select this option. The program will automatically estimate the accuracy.

• If no filter string is set, all images in the folder will be loaded.
• If only a panchromatic or multispectral image filter string is set, only the corresponding image type will be filtered.
• If both panchromatic and multispectral image filter strings are set, panchromatic and multispectral images that meet their respective filters will be loaded separately.

Available after Image Filtering Criteria is checked.

Sets the string used to filter multispectral images. Only images whose file names contain this string will be loaded.

Available after Image Filtering Criteria is checked.

Sets the string used to filter panchromatic images. Only images whose file names contain this string will be loaded.

Available after selecting Existing Data in Source of Data.

Specifies the cloud cover dataset. The dataset must contain an ImageName field, and the name must correspond to the image currently to be processed.

Available after selecting Cloud Detection in Source of Data.

The minimum number of pixels retained by the mask. Areas with pixel counts greater than this threshold are judged as cloud regions; if less, they are judged as non-cloud regions, and mask data is not retained. Default value is 4096.

Reference data serves as the base with accurate geographical location. During imagery processing, control points will be generated based on the reference data to perform geometric correction on the images.

Provides four ways to input image files: Add File, Add Folder, Add List, and Add Mosaic Data. When selecting Add Folder, it will automatically acquire all image files within that folder (including subfolders).

Note:

If you only need to perform color balancing and mosaicking on general image data of L4 level or above, adding reference data is unnecessary.

Selects the source of data for elevation data, providing the following three methods:

• SRTM V4 (default option): Elevation data comes from the fourth version of global 90-meter SRTM data in the remote sensing resource environment.
• Fixed Elevation Value: Input a custom elevation value.
• User Elevation Dataset: Load elevation information by specifying DEM Data. Supports four formats: Tiff/GeoTIFF, Erdas Image, PCIDSK, and ArcInfoGrid. Among these, ArcInfoGrid format data can only be acquired by clicking the Add Folder button.

When elevation data is orthometric height referenced to sea level, a geoid is needed to convert it to ellipsoidal height. When elevation data is already ellipsoidal height, this selection is not required.

• When Elevation Data Type is SRTM V4, this checkbox is checked by default.
• When Elevation Data Type is Fixed Elevation Value, this parameter is not provided.
• When Elevation Data Type is User Elevation Dataset, this checkbox is unchecked by default. You need to decide whether a geoid file is needed based on the elevation data.

Checked by default. It builds pyramids for the reference image data according to the specified resampling method, thereby improving image zoom display rendering and performance.

Will be automatically applied to all processes and result data in the workflow production.

Available after Create an Image Pyramid is checked.

Default is Average. For more method introductions, please refer to Resampling Method.

Will be automatically applied to all processes and result data in the workflow production.

During image browsing, the layer will be stretched according to statistics information. If the image lacks statistics information, it will be displayed using the default stretch method, and no stretch display will be applied to 8-bit data. Checked by default, meaning statistics will be created for the image in the background without affecting workflow execution. If unchecked, statistics will be created while executing this tool, which may consume time.

Will be automatically applied to all processes and result data in the workflow production.
