2DGridAccumulator

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

Jump to Configuration

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.
