Set Image Path

Feature Description

The Set Image Path tool is used to add original images and reference images to the workflow, along with setting global parameters such as coordinate system for data processing and result path.

In predefined image processing flows, you only need to set parameters in Set Image Path to execute the workflow and complete DOM data production.

Supported since SuperMap ImageX Pro 11i(2023) version.

Feature Entry

DOM Automated Processing Flow window → Set Image Path node.

Parameter Description

Parameter Name	Description	Type
Processing Path	Set a local path to store all intermediate and result data generated during data processing.	File
Zone Output	Specify whether to output images from different locations in their respective zoned coordinate systems. Unchecked by default, meaning all images will be output using a unified coordinate system. Checked: Requires setting the Projection Type, Banding Method, and Add a Number parameters. The program will automatically calculate the corresponding projected coordinate systems based on these three parameters and the image locations, outputting images from different locations separately based on their respective zoned coordinate systems. Unchecked: Requires setting the Output Coordinate System parameter. All images will be output uniformly using this coordinate system. Automatically applied to all processes and result data in the workflow. Note: Only effective when executing the complete workflow. If only executing individual tools in the workflow, the output coordinate system may differ from this setting.	Boolean
Projection Type	This parameter becomes available when Zoned Output is checked. Two projection methods are provided: Universal Transverse Mercator (WGS 1984), Gauss-Kruger (CGCS 2000). Default: Gauss-Kruger (CGCS 2000).	ZonePrjcoordSysType
Banding Method	This parameter becomes available when Zoned Output is checked. The zoned projection can be specified as either 6-degree zones or 3-degree zones, with 6-degree zones set as the default.	ImageZoneType
Add a Number	This parameter becomes available when Zoned Output is checked. Specifies whether to include the zone number in the projected coordinate system. Check this box to enable zone numbers in the projected coordinate system. Leave unchecked to disable zone numbers.	Boolean
Output Coordinate System	This parameter becomes available when Zoned Output is unchecked. Set the coordinate system for imagery output. All intermediate and result data will use this coordinate system.	PrjCoordSys
Output Format	Set storage type for result images. Options: Undefined, Tiff/GeoTIFF, Erdas Image, and PCIDSK. Default: Tiff/GeoTIFF, indicating output using original image storage type. Automatically applied to all processes and result data in the workflow.	FileType
Compression Method	Available only when Output Format is Tiff/GeoTIFF. Default: NONE. For more methods, see Compression Method. Automatically applied to all processes and result data in the workflow.	CompressMethod
Plane Accuracy	Determines whether to perform rough correction on original images. Default: High (no correction). Selecting Medium or Low enables rough correction. Low: Indicates planar accuracy error exceeds 40 pixels. High: Indicates planar accuracy error less than 15 pixels. Medium: Automatically estimates accuracy when uncertain.	ImageAccuracy
Panchromatic Image	Set panchromatic image path. Input methods: Add File, Add Folder, Add List, Add Mosaic Data. Add Folder automatically retrieves all image files (including subfolders).	File
Multispectral Image	Set multispectral image path. Input methods: Add File, Add Folder, Add List, Add Mosaic Data. Add Folder automatically retrieves all image files (including subfolders). Note: Panchromatic and multispectral images must be paired 1:1. Unpaired images will trigger the Image Pairing dialog for management.	File
Satellite Sensor Type	Set satellite sensor type for original images. Different sensors have unique spectral response functions and bit depths. Supported sensors: GF, ZY3-02, SuperView-1, IKONOS, WorldView, Landsat, ZY1-02D, Sentinel-2, etc.	SensorCategory
Image Filtering Criteria	Default: Unchecked (loads all images). When checked: No filter string: Load all images. Single filter: Apply to either panchromatic or multispectral images. Dual filters: Apply separately to both image types.	Boolean
Multispectral Filtering String	Available when Image Filtering Criteria is checked. Loads multispectral images containing this string in filenames.	String
Panchromatic Filtering String	Available when Image Filtering Criteria is checked. Loads panchromatic images containing this string in filenames.	String
Create Image Pyramid	Default: Checked. Builds pyramids using specified resampling method to improve display performance.	Boolean
Resampling Method	Available when Create Image Pyramid is checked. Default: Average. For more methods, see Resampling Method.	ResamplingMethod
Reference Image	Reference data with accurate geolocation for generating control points during geometric correction. Input methods: Add File, Add Folder, Add List, Add Mosaic Data. Add Folder automatically retrieves all image files (including subfolders). Note: Not required for color balancing and mosaicking of L4+ general image data.	File
Load According to Original Image Range	Default: Checked. Loads reference images within original image extent to accelerate processing.	Boolean
Create Reference Image Statistics	Enables layer stretching during image browsing based on statistics. Default: Unchecked (no statistics created). Unstretched 8-bit data displays without stretching.	Boolean
Create Image Pyramid	Default: Checked. Builds pyramids for reference data using specified resampling method to improve display performance.	Boolean
Resampling Method	Available when Create Image Pyramid is checked. Default: Average. For more methods, see Resampling Method.
Cloud Amount Data	Default: Unchecked. When checked, filters original images based on cloud amount data.	Boolean
Data Source Type	Available when Cloud Amount Data is checked. Options: Existing Data or Cloud Detection. Default: Existing Data.	CloudMaskDataSourceType
Data Source	Available when Data Source Type is Existing Data. Specifies datasource containing cloud amount dataset.	DataSource
Dataset	Available when Data Source Type is Existing Data. Specifies cloud amount dataset.	DatasetVector
Mask Pixel Threshold	Available when Data Source Type is Cloud Detection. Minimum pixel count for cloud region identification. Default: 4096.	Integer
Time	When checked, loads images within specified time range.	Boolean
Resolution	When checked, loads images within specified resolution range (meters).	Boolean
Cloud Coverage	Available when Cloud Amount Data is checked. When checked, loads images with cloud coverage ≤ specified value.	Boolean
Remove Duplicate Images	When checked, removes duplicate images based on filenames.	Boolean
Elevation Data Type	Select elevation data source: SRTM V4: Default. Uses 90m global SRTM data. Fixed Elevation Value: Input custom elevation. User Elevation Data: Specify DEM data (Tiff/GeoTIFF, Erdas Image, PCIDSK, ArcInfoGrid).	ElevationDataType
Use Geoid	Required when elevation data uses orthometric height (sea level reference). Not needed for ellipsoidal heights.	Boolean
Geoid File	Available when Use Geoid is checked. Specifies local geoid file.	File
