Description
The SmoothFeatures process adds vertices to features by applying a B-spline function.
Inputs
Features in a supported format. HOB and 000 (S-57 specification) are supported.
Outputs
Features in HOB format.
Command Line Syntax
carisbatch --run SmoothFeatures --feature-catalogue <value> --b-spline-order <value> [options] <input> <output>
User Interface Command
Simplify/Smooth
Options
The following table describes the parameters available for this process.
Parameter |
| |||
|---|---|---|---|---|
Long | Short | Description | Can Repeat | Notes
|
--feature-catalogue | F | A string specifying the name of the catalogue that defines the features and attributes in a vector dataset. One of {list dynamically populated from the catalogue control file}. The names of the available catalogues can be accessed through application via the Object Catalogue environment variable in Tools > Options. The available catalogues are controlled by the Catalogue Control file. An example of a catalogue name is "S-57 ENC 3.1". | FALSE | This must be specified for HOB input. |
--b-spline-order | B | A number specifying the degree of smoothing to apply. The number must be between 3 and 10. A larger value results in more vertices being added to create smoother features. | FALSE | This must be specified explicitly. |
Example
To use this command refer to the following example.
Example | ||
|---|---|---|
Objective | Contours have been generated and now need to be smoothed. | |
Description | Command Line Syntax | |
The Bathy DataBASE catalogue is to be used. | --feature-catalogue "Bathy DataBASE" | |
Smoothing is to be applied to a degree of 6. | --b-spline-order 6 | |
The data source is named ContourFeatures.hob and is located in the BatchSample directory, on the D drive. | D:\BatchSample\ContourFeatures.hob | |
The smoothed contours will be saved to a new file named SmoothedContours.hob in the data source location. | D:\BatchSample\SmoothedContours.hob | |
Command Line |
| |
Outcome | A new HOB file is created containing the new smoothed contour features. | |
