CREATE GRID
|
|
===========
|
|
|
|
Description
|
|
-----------
|
|
This algorithm creates a grid and adds it to the map canvas. You can decide the extent of the grid, the spacing between the
|
|
lines and the output file type (lines or polygons layer according to the grid type option). Moreover you can choose the
|
|
position of the grid (according to the center of the grid) and the corrdinate reference system (CRS).
|
|
|
|
Parameters
|
|
----------
|
|
|
|
- ``Horizontal spacing[Number]``: x-axes spacing between the lines (meters)
|
|
- ``Vertical spacing[Number]``: y-axes spacing between the lines (meters)
|
|
- ``Width[Number]``: horizontal extent of the grid
|
|
- ``Height[Number]``: vertical extent of the grid
|
|
- ``Center X[Number]``: x-coordinate of the grid center
|
|
- ``Center Y[Number]``: y-coordinate of the grid center
|
|
- ``Grid type[Selection]``: 4 grid types availables
|
|
- Rectangle (line)
|
|
- Rectangle (polygon)
|
|
- Diamond (polygon)
|
|
- Hexagon (polygon)
|
|
|
|
Outputs
|
|
-------
|
|
|
|
- ``Output[Vector]``: the resulting grid (lines or polygons) layer
