This tool converts a polygon feature class to an integer raster using the ObjectID of the feature class for the value of the output raster. This tool is based upon the "Polygon to Raster" conversion tool and is intended to be used for Dasymetric Mapping.
The output raster will contain unique population source units and their associated population.
Expression | Explanation |
---|---|
<Population_Features> |
The population input polygon featureclass to be converted to a raster. |
<Population_Count_Field> |
Specify the field in the population dataset that contains count data. |
{Population_Key_Field} |
Since the tool will always use the system-recognized ObjectID field for the output raster Values, this is for your reference only and is not used by the tool. It can be helpful to have another key field (commonly census FIPS code) for joining the outuput raster to other tables. |
<Ancillary_Raster> |
The ancillary raster dataset to be used to redistribute population. The output raster from this tool will be snapped to the ancillary raster and have matching spatial reference and cell size. |
{CELL_CENTER | MAXIMUM_AREA | MAXIMUM_COMBINED_AREA} |
The method to determine how the cell will be assigned a value when more than one feature falls within a cell.
|
<Population_Raster> |
The output population raster dataset that will be created, inlcuding the full path. When you're not saving to a geodatabase, specify .tif for a TIFF file format, .img for an ERDAS IMAGINE file format, or no extension for a GRID file format. |
<Population_Working_Table> |
The tool will create a standalone table for performing calcluations. Please enter a name and path for the output table. |
