Snap Point

Description

Snap input point features to closest cell in the input Snap Stream Grid raster using the specified snapping distance.

If the input point has SnapOn set to 0, it will not be moved. Otherwise, if SnapOn does not exist or is set to 1:
- If the input point is located outside of the snapping distance, it will be moved to the center of the cell.
- If the input point is located within the snapping distance, it will be snapped to the center of the closest cell with a valid value and the field SnapDist will be populated with the distance the point was moved.

Direction	Type	Parameter Name	Data Type	Dialog Reference
Input	Required	Input Batch Point Feature Class	GPFeatureRecordSetLayer	Input Point features to snap. This feature class must contain the following attributes: HydroID: Unique identifier of the input point. Used to populate the HydroID field in the output SnapPoint feature class. If not present, the ObjectID field will be used instead. SnapOn (Optional): 0/1. Indicates whether the tool should try to snap the point feature.
Input	Required	Input Snap Stream Raster	GPRasterLayer	Input raster used to snap the points.
Input	Required	Snapping Distance in Linear Units or Field	Field
Output	Required	Output Snap Point Feature Class	GPFeatureLayer	Output Snap Point features populated with the following attributes: HydroID: Unique identifier of the feature. FeatureID: HydroID ( or ObjectID) of associated input point. SnapOn: 0/1. Indicates whether the tool tried to snap the point. Populated with 1 if SnapOn field does not exist in input Batch Point feature class or is populated with 1. Snapped: 0/1. Indicates whether the point was snapped. SnapDist: Distance by which the point was moved in linear units. Populated with -1 if the input point could not be snapped.
