Raster to Point (Conversion)

Summary

Converts a raster dataset to point features.

Usage

• For each cell of the input raster dataset, a point will be created in the output feature class. The points will be positioned at the centers of cells that they represent. The NoData cells will not be transformed into points.

• The input raster can have any cell size and may be any valid raster dataset.

• The Field parameter allows you to choose which attribute field of the input raster dataset will become an attribute in the output feature class. If a field is not specified, the cell values of the input raster (the VALUE field) will become a column with the heading Grid_code in the attribute table of the output feature class.

Syntax

RasterToPoint_conversion (in_raster, out_point_features, {raster_field})

Parameter	Explanation	Data Type
in_raster	The input raster dataset. The raster can be integer or floating-point type.	Raster Layer
out_point_features	The output feature class that will contain the converted points.	Feature Class
raster_field (Optional)	The field to assign values from the cells in the input raster to the points in the output dataset. It can be an integer, floating point, or string field.	Field

Code Sample

RasterToPoint example (Python window)
