Multispectral and Panchromatic Registration

Feature Description

Multispectral and panchromatic registration aligns the multispectral image based on the panchromatic image to ensure the quality of image fusion.

SuperMap ImageX Pro is supported starting from version 11i(2023).

Parameter Description

Parameter Name	Description	Type
Dataset	Displays the original multispectral image data used for registration and cannot be edited.	DatasetMosaic
Use ortho panchromatic data	Checked by default. Uses Generate Orthophotos results as reference data. When unchecked, uses panchromatic data from original image as reference data.	Boolean
Panchromatic data	Available when Use ortho panchromatic data is checked. Displays the orthorectified panchromatic image dataset and cannot be edited.	DatasetMosaic
Correction model type	Provides Linear RPC Correction Model, Quadratic Polynomial RPC Correction Model, and Cubic Polynomial RPC Correction Model. Linear RPC Correction Model is selected by default. Linear RPC Correction Model: Suitable for images with minor internal distortion. Requires at least 4 ground control points (GCPs). Add GCPs via Manage Ground Control Points. Quadratic Polynomial RPC Correction Model: Suitable for moderate internal distortion. Requires at least 9 GCPs. Add GCPs via Manage Ground Control Points. Cubic Polynomial RPC Correction Model: Suitable for significant internal distortion. Requires at least 16 GCPs. Add GCPs via Manage Ground Control Points.	CorrectedModelType
Number of blocks in column direction	Number of column blocks for image division. Default: 12.	Integer
Number of blocks in row direction	Number of row blocks for image division. Default: 4.	Integer
Minimum points per block	Minimum matched points per image block. Default: 1000.	Integer
Cloud mask	Sets the data source of the cloud mask dataset.	DataSource
Dataset	Automatically removes tie points within dataset bounds using cloud mask data. No cloud mask dataset is set by default (retains all tie points).	DatasetVector
Building detection	Unchecked by default (no building area detection). When checked, automatically detects building areas and removes all tie points within detected ranges.	Boolean
Export directory	Uses the Processing path parameter from Set Image Path and cannot be edited.	File
Resolution type	Specifies output image resolution method. Default: Original resolution. Original resolution: Maintains input image's original resolution. Fixed Value: Uses specified value as output resolution. Custom: Outputs different resolutions based on satellite sensor types. Selecting this option opens the Custom Resolution: dialog. Click Add to create entries, select sensor types in Satellite sensor type column, and input corresponding resolutions in Resolution column. Notes: Select USEDEFINE if the corresponding satellite sensor type is not found. This option uses the resolution specified for USEDEFINE for all unsupported sensor types. When processing images from multiple sensor types (e.g., ZY3, GF-2, LandSat) with only one sensor's resolution configured (e.g., ZY3), other sensor types will output at their original resolutions.	OrthoRatioType
Coordinate system settings	Uses the Output coordinate system parameter from Set Image Path and cannot be edited.	PrjCoordSys
Output format	Uses the Output format parameter from Set Image Path and cannot be edited.	FileType
Compression method	Uses the Compression method parameter from Set Image Path and cannot be edited.	CompressMethod
Create image pyramid	Checked by default. Builds pyramids using specified resampling method to improve image display performance.	Boolean
Resampling method	Available when Create Image Pyramid is checked. Default: Average. For more methods, see Resampling Method.	PyramidResampleType
Asynchronously create statistics	Applies stretch display based on statistics during image browsing. Images without statistics will display using default stretch method (no stretch for 8-bit data). Checked by default (creates statistics in background without delaying workflow). Unchecking creates statistics during tool execution (may take time).	Boolean
