Feature to Raster (Conversion)
Summary
Converts features to a raster dataset.
Usage
-
Any feature class (geodatabase, shapefile or coverage) containing point, line, or polygon features can be converted to a raster dataset.
-
The input field type determines the type of output raster. If the field is integer, the output raster will be integer; if it is floating point, the output will be floating point.
-
This tool always uses the cell center to decide the value of a raster pixel. If more control over how different types of input feature geometries are to be converted, please refer to the respective specific conversion tools: Point to Raster, Polyline to Raster, and Polygon to Raster.
-
This tool is a complement to the Raster to Point, Raster to Polyline, and Raster to Polygon tools, which convert a raster to different types of feature dataset geometries.
When selecting the input feature data, the default field will be the first valid field available. If no other valid fields exist, the ObjectID field (for example, OID or FID) will be the default.
Only the Build pyramids setting in the Pyramid environment settings is honored. The remaining Pyramid environment settings are ignored, along with any other Raster Storage environment settings. More control over the nature of the pyramids can be obtained in a subsequent step by using the Build Pyramids tool.
Syntax
| Parameter | Explanation | Data Type |
in_features |
The input feature dataset to be converted to a raster dataset. | Feature Layer |
field | The field used to assign values to the output raster. It can be any field of the input feature dataset's attribute table. If the Shape field of a point or multipoint dataset contains z or m values, then either of these can be used. | Field |
out_raster | The output raster dataset to be created. When not saving to a geodatabase, specify .tif for a TIFF file format, .img for an ERDAS IMAGINE file format, or no extension for an Esri Grid raster format. | Raster Dataset |
cell_size (Optional) | The cell size for the output raster dataset. The default cell size is the shortest of the width or height of the extent of the input feature dataset, in the output spatial reference, divided by 250. | Analysis Cell Size |
