The remaining Pyramid environment settings are ignored. An easy way to do this is to add an additional field to the input feature class and calculate it to the inverse area of the polygons then use this field as the Priority field when running this tool.įor data formats that support Null values, such as file geodatabase feature classes, a Null value will be ignored when used as input.Ĭertain raster storage environments may apply to this tool.įor the Pyramid environment, only the Build pyramids setting is honored. When converting overlapping polygons, you may want the polygons with the smallest area to be assigned to a cell. If stripes or bleeding occur in the output raster, use the Check Geometry and Repair Geometry tools to correct the input feature data. When more than one feature is present in an output cell, this tool provides greater control over the assignment of cell values than the Feature to Raster tool. This tool is a complement to the Raster to Polygon tool, which converts a raster to a polygon feature class. If the spatial reference of the dataset is different, it will be projected based on the selected Cell Size Projection Method. The cell size of that raster dataset will be used directly in the analysis, provided the spatial reference of the dataset is the same as the output spatial reference. If the cell size has been specified using a raster dataset, the parameter will show the path of the raster dataset instead of the cell size value. If the cell size has been specified using a numeric value, the tool will use it directly for the output raster.
If nothing has been specified, the cell size is calculated from the shorter of the width or height of the extent divided by 250, where the extent is in the Output Coordinate System specified in the environment. If neither the parameter cell size nor the environment cell size has been specified, but the environment Snap Raster has been set, the cell size of the snap raster is used. If the cell size hasn’t been explicitly specified as the parameter value, it is derived from the environment Cell Size, if it has been specified. The Cellsize can be defined by a numeric value or obtained from an existing raster dataset. However, if the field is of type floating point and the values are expressed as integers, then the output raster will be integer. If the input field contains string values, the output raster will contain an integer value field and a string field. If the field is integer, the output raster will be integer if it is floating point, the output will be floating point. The input field type determines the type of output raster. Any feature class (geodatabase, shapefile, or coverage) containing polygon features can be converted to a raster dataset.
