public class ContourWithBarriers
extends AbstractGPTool

Creates contours from a raster surface. The inclusion of barrier features will allow one to independently generate contours on either side of a barrier. The Contour with Barriers tool is contained in the Spatial Analyst Tools tool box.

Usage tips:

• The current version of Contour with Barriers only supports polyline output. If the polygon output option is used it will be ignored and polyline output will be created.
• Smoother but less accurate contours can be obtained by pre-processing the input raster with a operation with the MEAN option or the tool with the LOW option.
• Contours will extend into the raster's NoData cell by a distance of half the raster's cell size. This will mean that the contours will be generated over single NoData cells. However, a 3-cell-by-3-cell area of NoData will only have the contours extending into this area by half the cell size distance.
• The Type field in the output contour feature class has values: 1 for contours 2 for indexed contours 3 for explicit contours
• An indexed contour interval can be used to generate additional contours and their Type value will be coded as 2 in the output feature class.
• 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.
• A text file containing contour value specifications can include the following:For example, if a raster has a minimum value of 102 and a maximum of 500, then a text file with: # contour values and ranges 122.75 485 500 5 12 4 100 99will produce contours at: 122.75 104, 204, 304, 404 103, 202, 301, 400, 499 485, 490, 495, 500 497
• If there are cell values of the raster within a barrier polygon feature the contour lines will be split at the barrier. If the cell values within the polygon feature are to be ignored, change those cell values to NoData.
• If the input raster surface is very large or many output features are requested, a large number of temporary files will be created in the operating system's temporary file location. If any problems are encountered as a result of this do one of the following:
• The output contour features can be labeled by using the tool.
