GPTool

public class Contour
extends AbstractGPTool

Creates contours or isolines from a raster surface. The Contour tool is contained in the Spatial Analyst Tools tool box.

Software restrictions: none

Usage tips:

• Contours do not extend beyond the spatial extent of the raster, and they are not generated in areas of NoData. Therefore, adjacent contour inputs should first be edgematched into a continuous feature dataset. As an alternative to edgematching, you can merge the adjacent rasters before computing contours.
• Contours can be generated in areas of negative raster values. The contour values will be negative in such areas. Negative contour intervals are not allowed.
• Smoother but less accurate contours can be obtained by first performing a Neighborhood Focal Statistics operation with the Mean option on the input raster.
• A base contour is used, for example, when you want to create contours every 15 meters, starting at 10 meters. Here, 10 would be used for the base contour, and 15 would be the contour interval. The values to be contoured would be 10, 25, 40, 55, and so on.
• Specifying a base contour does not prevent contours from being created above or below that value.
• The following environment settings affect this tool:

Initializes the array of tool parameters with the default values specified when the tool was created.

Contour

public Contour(Object inRaster,
               Object outPolylineFeatures,
               double contourInterval)

Creates the Contour tool with the required parameters.

Initializes the array of tool parameters with the values as specified for the required parameters and with the default values for the other parameters.

Parameters:

inRaster - Composite Geodataset, input raster.

outPolylineFeatures - Feature Class, output contour polyline features.

contourInterval - Double, this can be any positive number.
