Chops all input features into a series of tiles, covering the extent of all features.  

Tile size may be specified in ground units or calculated from a specified number of columns and rows to cover the extent of all features. Tiles are numbered relative to the chosen starting corner.

When Define Tiles By is Dimensions in Ground Units, tile dimensions are specified in ground units. Features in a latitude/longitude coordinate system may need to be reprojected prior to tiling.

Features that span multiple tiles will be clipped into multiple features.  

This transformer works with raster, vector and point cloud data.

Note: If you are inputting raster data, you may want to use the RasterTiler instead. The following table compares the Tiler and the RasterTiler:

Type of data accepted All types except surfaces and solids Raster only
Tile size units Ground coordinates Pixel coordinates
Tile row numbering (0, 1,...) Selectable Top to bottom
Supports forcing equal-size tiles No Yes
Supports raster index attribute No Yes
Supports number of horizontal/vertical tiles attribute No Yes


Usage Notes

  • For temporary reprojection of geographic data for defined tile size, the CommonLocalReprojector may be useful.

  • This transformer tiles the input features - it does not create a new grid. To create a grid (points or polygons) over the extent of your features, use a 2DGridAccumulator. To generate a grid independent of other features, consider the 2DGridCreator.

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.
