RasterMosaicker

This transformer mosaics multiple raster features into a single raster feature.

The transformer accepts a number of input raster features, each of which has one or more bands. All the raster features have the same number of selected bands, which, in turn, have the same number of selected palettes. Each selected band from each input raster feature will be removed, mosaicked together, and then appended to a single output raster feature. As a result, the output raster feature will also have the same number of selected bands and palettes.

Input Features

  • This transformer accepts only raster features.
  • The order of the input features determines the order in which rasters will be drawn. The first raster to enter will be drawn first, then each subsequent raster will be drawn on top of any previous overlapping rasters. You can use a Sorter transformer to enforce the order in which the features are processed.
  • When there are no selected palettes or Merge Palettes is No, each band in a set must have the same band interpretation and nodata value.
  • When there are selected palettes and Merge Palettes is Yes, each band must have one selected palette, and all palettes must have the same value interpretation.

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.
