2.2.24. Meter grid

Pic. 2.14. A combination of generated grids

The tool generates a grid within the boundaries of features of a vector layer or a bounding box. The grid size is set in meters. Features can be anywhere in the world.

Inputs:

Cell size in meters;
Mode: points or rect (squares);
Algorithm for cropping the grid along the feature borders: all (leave all the squares in extent), touches (leave all the squares touching features), intersection (crop the squares along the borders of the features);
GeoPackage file with polygons or multipolygons. Calculation time depends on the number of nodes in the boundary layer;
Extent. Instead of uploading a layer, you can set a bounding box. Draw a custom rectangle on the map below. The Extent field will be filled with the numeric value that you can adjust manually;
Vertical orienting or with fine size. By default, simple mode is used, the grid looks vertical in WGS 84 (EPSG:3857) projection, but angles and distances may be distorted. Enter fine to get a grid with more precizely matching angles and distances, however it will look tilted in EPSG:3857.

Output:

GeoPackage containing the grid. Each cell/point of the grid has the following attributes: number (cells are numbered vertically, top to bottom, left to right, starting with the first left column even if it doesn’t reach the top), row_index and col_index. To display the numbers, enable lables in the layer style settings and select the desired attribute.
