Method CreateAsync
CreateAsync(IEnumerable<string>, int, SpatialReference?, CancellationToken)
Creates a boolean field from one or more raster files.
Declaration
public static Task<BooleanField> CreateAsync(IEnumerable<string> filePaths, int band, SpatialReference? spatialReference = null, CancellationToken cancellationToken = default)Parameters
| Type | Name | Description |
|---|---|---|
| IEnumerable<string> | filePaths | One or more raster file paths. |
| int | band | Zero-based index identifying a raster band. |
| SpatialReference | spatialReference | The spatial reference into which to project the raster content. Optional. |
| CancellationToken | cancellationToken | A cancellation token that can be used to cancel the operation. |
Returns
| Type | Description |
|---|---|
| Task<BooleanField> | A task BooleanField created from raster files, or an error if creation of a BooleanField is unsuccessful. |
Remarks
If a spatial reference is not given, the spatial reference of the first raster file is used.
If a spatial reference is given, the raster content is projected into that spatial reference using the most suitable transformation available. Projection transforms only the horizontal coordinate system, not the field values.
The field extent is the union of the raster file extents.
Supports reading of all raster pixel types except float (32-bit or 64-bit). Boolean values are derived as
true when the source value is non-zero. Returns an error if creation of a BooleanField is unsuccessful.
