Esri Geodatabase (File Geodb Raster Dataset) Writer Feature Type Parameters

To access feature type parameters, click the gear icon on a feature type in the workspace. This opens the Feature Type Parameter Editor.

Tip: To always display the editor in Workbench, you can select View > Windows > Parameter Editor.

General

All feature types share similar General parameters, which may include Feature Type Name, Reader or Writer information, and Geometry.

In most Writer Feature Type parameter dialogs, you can also control Dynamic Schema Definitions. Some database formats accept Table or Index Qualifier prefixes on the output table feature type.

Raster Dataset

When this option is set to Yes, the writer will drop the table before writing, and create a new one. If the table does not exist, it will be created when the data is written. The default is No.

Note: This parameter is valid only if the feature reaches the writer.

Raster

Compression

This parameter defines the type of compression to use on the table.

Values:

  • JPEG
  • JPEG2000: Available only on rasters with an 8-bit pixel depth and no colormap.
  • LZ77: The only valid compression option for images with a colormap.
  • None

The degree of lossiness caused by the compression. Valid values are integers from 0 (lowest quality) to 100 (highest quality).

This value is ignored when not using one of the JPEG compression types.

Pyramid Generation

Determines the resampling type to be used when generating reduced resolution pyramids on the destination raster dataset.

  • Nearest Neighbor – Provides the fastest output but the poorest quality.
  • Bilinear Interpolation – Determines the new value of a cell based on a weighted distance average of the four nearest input cell centers.
  • Cubic Convolution – Provides the best quality, but can require more processing time.

Specifies the number of reduced resolution pyramids to build.

More pyramids enable better performance when viewing raster data using FME and Esri products.
