GPTool

public class SplineWithBarriers
extends AbstractGPTool

Interpolates a raster surface, using barriers, from points using a minimum curvature spline technique. The barriers are entered as either polygon or polyline features. The Spline with Barriers tool is contained in the 3D Analyst Tools tool box.

Usage tips:

• This tool requires the Java runtime environment Version 6, or higher, to be installed. The Java Runtime Environment can be downloaded for free from .
• The resulting smooth surface from is constrained by the input barrier features.
• Some input datasets may have several points with the same x,y coordinates. If the values of the points at the common location are the same, they are considered duplicates and have no affect on the output. If the values are different, they are considered 'coincident' points.The various interpolation tools may handle this data condition differently. For example, in some cases the first coincident point encountered is used for the calculation; in other cases the last point encountered is used. This may cause some locations in the output raster to have different values than what you might expect. The solution is to prepare your data by removing these coincident points. The tool in the Spatial Statistics toolbox is useful for identifying any coincident points in your data.For the Spline with Barriers tool, by default the values for each set of coincident points will be averaged.
• If a cell size of zero is entered, the cell size actually used will be the shorter of the width or the height of the extent of the input point features, in the input spatial reference, divided by 250.
• The barrier features are rasterized and the cell center is used to decide whether the cell falls within a polygon or whether the cell becomes a barrier for polyline features.
• If the tool fails to run with an error message stating that a "more recent version of Java needs to be installed", and you have multiple versions of Java installed, you need to update the PATH environment variable.
