Resumen
Converts a polygon, polyline, or point feature class to a raster object.
Debate
For more information about how this function works, see the Rasterize Features raster function.
The referenced raster dataset for the raster object is temporary. To make it permanent, you can call the raster object's save method.
Sintaxis
RasterizeFeatures (raster, feature_class, {class_index_field}, {resolve_overlap_method})
Parámetro | Explicación | Tipo de datos |
raster | The raster used to define the cell size and extent for the feature conversion. | Raster |
feature_class | The point, line, or polygon feature class to convert to a raster object. Supported options include the path to the feature class or a FeatureSet. | String |
class_index_field | The feature class field to assign values to pixels in the rasterized output. If no field is provided, pixel values will be assigned using the feature class's OBJECTID field. (El valor predeterminado es None) | String |
resolve_overlap_method | Specifies the method to assign pixel values in areas where features are overlapping.
(El valor predeterminado es FIRST) | String |
Tipo de datos | Explicación |
Raster | The raster object containing pixel values from the input features. |
