Overview
The Rasterize Attribute function enriches a raster by adding bands derived from values of specified attributes, from an external table or a feature service.
You can optionally specify a zone raster and the associated zone ID attribute to enable regional lookups.
Notes
If a multiband raster is used as an input, only the first band and the rasterized attributes will be retained.
Parameters
| Parameter name | Required? | Description |
|---|---|---|
| Input Raster | Yes | The input raster. The input should be a single-band raster. If a multiband raster is used, then only the first band will be used. |
Zone Raster | No | An optional single-band raster where each pixel contains the zone ID associated with the location. The zone ID is used for looking up rows in the zonal attributes table for zone-specific ingestion. Leave this parameter unspecified if you only want to import the attribute. |
Zonal Attributes Table | No | The zonal attributes specified as a path to a local feature class, the path to a table, the URL to a feature service layer, or a JSON string. In JSON, it is described as a collection of mapping from zone IDs to an array of integers. { zoneId:[f1,f2,...,fn], ... } |
Zone ID Field Name | No | The field name containing the zone ID values. |
Attribute Names | No | List of fields in the Zonal Attributes Table, where each field is separated by a comma. Values in each field will be represented by a band in the output raster. |
Background Value | No | The initial pixel value of the output bands in raster, prior to being remapped. If a pixel does not fall within a zone it will remain as the background value. |
Where Clause | No | An optional additional query applied on the Zonal Attributes Table. If you were using the table above as an example, the query would be Variable1 = 'bare earth'. |
