Define the contour level options.
Contours are created according to the elevation values in the source surface. You can create contours at regular intervals in the elevation or you can create contours at specific values defined in a contour levels file. For example:.
A sample list is provided. You can use the sample file as is or you can make a copy of it and edit it as needed. The sample list is called DepthListSample.txt and can be found in this folder:
C:\ProgramData\CARIS\BASE Editor\<version>\SampleData |
Interface
Option | Description |
|---|---|
Range | The range of elevation values in the selected height source. When contouring by range, you can use the entire range in the source or you can create your own range. |
Min (m) | The minimum value to include in the range if contouring a specific range of values. |
Max (m) | The maximum value to include in the range if contouring a specific range of values. |
Interval | The frequency with which contours are created based on the elevation difference between each contour in the range of values. For example, you could create contours at every 5 metres. |
Add | Generate the contour levels for the specified range and interval. The box at the right displays the contour levels. |
Contour levels list | The elevation values at which contours will be generated. Once the contour levels list contains data, a pop-up menu becomes. It contains the following commands: • Insert: Manually add a contour level to the list using the Add Contour Level dialog box. This is useful if a contour is needed at a specific level but the level was not generated automatically. • Delete: Remove the currently selected level from the list. To delete multiple levels, press and hold <Ctrl> while selecting the levels and then select this command. • Save: Save the current contour levels list to a text file for future use with the contour levels file field. Specify a name and location for the file . • Clear: Remove all current levels from the list. This is also available using the Clear button. |
Contour levels file | Navigate to and select a contour levels file. The name and the location of the file will be displayed in the field. |
Load | Display the contour levels list with the values from the selected contour levels file. |
Clear | Remove all values from the contour levels list. |
Procedure
1. Display contour levels in the list using one of the following methods:
• Enter values for Min (m), Max (m) and Interval (m) then click Add.
• Click browse (...) for the Contour levels file option, select a file then click Load.
2. Click Next.
