Description
The points added to the map or in the selected layer are outside of the extent of the Input Cost Surface parameter value. The points must be inside of this extent to process the dataset.
Solution
If adding points interactively, delete the points and add new points that are inside of the extent of the Input Cost Surface parameter value. If selecting a layer, visually compare the points to the Input Cost Surface parameter value to ensure that they are contained within its extent. If this is the case and you continue to receive this error, you can use the Project tool to project the point layer to match the spatial reference of the Input Cost Surface parameter value.
