Match Control Points

imageCollection

The image collection (mosaic dataset) name or URL. The image service must exist before calling MatchControlPoints .

Syntax: A JSON object supports three keys: itemId, url, and uri. These keys are case sensitive.

Example:

1
2
3
{"itemId": “<portal item id>”}
{“url”: “<image service url>”}
{“uri”: “<cloud raster uri or shared data path>”}

inputControlPoints

(Required)

The ground control points (GCP) sets written as a JSON object. The similarity tolerance for finding control points will be low.

Syntax: The schema of the control points' JSON follows the schema of the mosaic dataset's control point table. The control points must contain one geometry and attribute set. There are two types of control points determined by the type attribute: tie points and ground control points .

similarity

(Optional)

Sets the similarity tolerance level for your matching control point. Low tolerance will produce the most control points, but some may have a higher level of error. Medium tolerance will produce a medium amount of control points. High tolerance will produce the least number of control points, but each matching pair will have a lower level of error. High tolerance is the default value.

context

Identifies additional settings such as the input control points spatial reference, which can be specified here. The context parameter is used to define both groundControlPointsSpatialReference and imagePointsSpatialReference . If these two parameters are not defined, the tool will use the spatial reference defined in the input point set. If no spatial reference is defined in the input point set, the default ground control point coordinates are in longitude-latitude, and the image points coordinates are in the image coordinate system.
