Get the fractal dimension
This program allows to apply the box counting technique to estimate the fractal dimension of a polygonal figure of one or more pieces, contained in the file on which the process will be run. The program returns 6 shapes with their respective mandatory files (shp, shx, dbf). The first shape contains the minimum square box that contains the analyzed figure. We call this level, N0. Subsequently, another five files are generated, the first of these (N1) divides the box of the first file into four equal squares. The next one (N2), a mosaic of 16 (4x4) squares, each one half the length of the previous ones, that fit inside these, and so on. After generating the files, the program delivers a list that indicates the number of squares in each file, and the number of occupied squares of each dimension inside the figure. You can estimate outside the QGIS program, the regression line whose slope is the dimension fractal. The largest square is l long. The second half of l, the third l / 2/2 and so on.
This complement was developed under the supervision of Dr. Luis Chías from GITS, Institute of Geography- UNAM. On whose page you can find more detailed information.
