Input: a reference layer (a feature or raster layer), or a set of bounding coordinates (XMin, XMax, YMin, YMax)
Output: a point layer of regularly spaced points

  • alternate rows can be offset from each other (the default is a perfectly regular grid)
  • for raster reference layers, the first point can optionally be placed in the centre of the top-left cell as opposed to the extreme top-left corner


  • there is currently no option to prevent points from being located in NoData cells
  • the program always starts in the upper-left corner of the extent of the reference layer

Figures A & B. In this example, an irregularly shaped raster layer is used as the reference layer (A). (Note that NoData cells have been coloured grey in order to display the true extent of the raster layer). Regular points, with a 10000m spacing were created (B).


Getting started. It is advisable to decide what will define the extent within which the regular points will be generated before you start the tool. This can either be a feature or raster layer, or a set of coordinates that you manually type in. Note that for reference layers, the extent is considered to be the rectangle that bounds the layer.
