Resamples rasters to multiple resolutions, based on either number of levels or dimensions of the smallest output raster.

Typical Uses

  • Preparing rasters for viewing at multiple zoom levels when tiling is not required, or if tiling has already been done.

How does it work?

The RasterPyramider accepts raster features, and “pyramids” them - resampling them to produce a set of output rasters at varying resolutions, appropriate for different zoom levels.

The number of rasters produced may be specified by Number of Levels, or by defining the smallest level size by number of columns and rows in cells (pixels).

Various methods are available for interpolation of pixel values during resampling.

Attributes may be added to the output tiles to record Pyramid level, original raster index, and number of levels produced.

This transformer is unaffected by raster band and/or palette selection.


Usage Notes

  • To tile and resample rasters using zoom levels and positions defined for various web mapping tile schemes, consider using the WebMapTiler.

Choosing a Raster Transformer

FME has an extensive selection of transformers for working with raster data. They can be generally categorized as working with whole rasters, bands, cells or palettes, and those designed for workflow control or combining raster with vector data.

For information on raster geometry and properties, see Rasters (IFMERaster).

Editing Transformer Parameters

Using a set of menu options, transformer parameters can be assigned by referencing other elements in the workspace. More advanced functions, such as an advanced editor and an arithmetic editor, are also available in some transformers. To access a menu of these options, click beside the applicable parameter. For more information, see Transformer Parameter Menu Options.

Defining Values

There are several ways to define a value for use in a Transformer. The simplest is to simply type in a value or string, which can include functions of various types such as attribute references, math and string functions, and workspace parameters. There are a number of tools and shortcuts that can assist in constructing values, generally available from the drop-down context menu adjacent to the value field.

Dialog Options - Tables

Transformers with table-style parameters have additional tools for populating and manipulating values.
