2.14. Set of squares generator

This tool creates a set of square grids (polygons) and a transect of their detour for a given territory.

Inputs:

  • x0 - Longitude of the anchor point

  • y0 - Latitude of the anchor point

  • x1 - Longitude of the reference point

  • y1 - Latitude of the reference point

  • size1 - Number of cells on the first axis

  • size2 - Number of cells on the second axis

  • side - Cell generation side (right, left)

  • base_interval - The size of a cell’s side, meters

Calculation algorithm: from the anchor point in the direction of the reference point a line is drawn with a length equal to size1 * base_interval. From this line, either to the right or left of it, a second line is laid out with the length of size2 * base_interval, meters. These two lines form a grid of squares.

The result of the process is a set of layers:

  • rect1 - a grid of cells the size of size1 * size2 cells, the center of the first cell is at the anchor point

  • rect2 - a grid of smaller cells the size of size1 * size2 cells (i.e. 4 times larger cells, each large cell is divided into 4 parts)

  • line1 - bypass lines in the direction, which if perpendicular to the line represented by the anchor point and reference point

  • line2 - bypass lines in the direction, which is parallel to the line represented by the anchor point and reference point

  • centers - grid cell centers rect1
