Creates a regular grid of points or rectangular polygons that span the extents of all input features.

Typical Uses

  • Generating grid for a specific dataset’s coverage

  • Creating reference grid in conjunction with a Tiler or RasterTiler

How does it work?

The 2DGridAccumulator receives features with geometry and creates a regular grid that covers the bounding box containing all features.

The grid may be composed of:

  • rectangular polygons,

  • points at the corners of each cell, or

  • points at the center of each cell.

Cell size may be either specified explicitly in ground units or calculated based on the number of cells desired both horizontally and vertically.

Columns and rows are numbered and may start in any of the four corners of the features’ bounding box.

If the cell size is explicit, seed coordinates for x and/or y may be applied to adjust the grid’s position.


Usage Notes

Creating Boxes and Rectangles

Creating rectangular geometry is a common task. These transformers do so in a variety of ways.

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.
