Match Control Points (Data Management)

Summary

Creates matching tie points for a given ground control point and initial tie point in one of the overlapping images.

Usage

• If the input control point set doesn't have a ground control point, the tool will fail.

• If the input control point set has ground control points but no initial tie point, the tool will fail.

• If no associated tie points are found, the input control point set remains unchanged, and a warning message appears that states no new tie points were found.

• An input control point set can be a JSON string object that is a list of points as shown below.

  Input control point sets

  "spatialReference":{<spatialReference>}, // default WGS84
  "imagePointSpatialReference": {}, // default ICS

Parameters

Dialog

Label	Explanation	Data Type
Input Mosaic Dataset	The mosaic dataset that contains the source imagery from which the tie points will be created.	Mosaic Dataset; Mosaic Layer
Input Control Points	The input control point set that contains a list of ground control point features and at least one initial tie point for each ground control point.	File; Feature Class; Feature Layer; String
Output Control Point Table	The output control point features that contain ground control points.	Feature Class
Similarity (Optional)	Specifies the similarity level that will be used for matching tie points. Low similarity—The similarity criteria for the two matching points will be low. This option will produce the most matching points, but some of the matches may have a higher level of error. Medium similarity—The similarity criteria for the matching points will be medium. High similarity—The similarity criteria for the matching points will be high. This option will produce the fewest matching points, but each match will have a lower level of error.	String

out_control_points	The output control point features that contain ground control points.	Feature Class
similarity (Optional)	Specifies the similarity level that will be used for matching tie points. LOW—The similarity criteria for the two matching points will be low. This option will produce the most matching points, but some of the matches may have a higher level of error. MEDIUM—The similarity criteria for the matching points will be medium.
