Tiling optimization case study code

This repository contains example code used in testing and illustrating development of the tiling optimization algorith and method for the GarminCustomMaps QGIS plugin.

A detailed description of all the code can be found at the Geospatial Development Documentation page.

Usage

factors_comparison.py:

• adjust parameters in the code:

    #Set up sample space
    n = 15
    x = np.logspace(1, n, num=50, base=2, dtype=np.uint32)
  

• run python factors_comparison.py

optimization.py:

• adjust parameters in the code:

    # Set up conditions
    x = 6000
    y = 6000
    max_tile_size = 1024 **2
    max_num_tiles = 100
    flag_plot = False
    ofunc = 'dtb'
    savefig = True
  

• run python optimization.py

ti.*:

• adjust code in ti_setup and ti_*

• run with timeit:

    $ python -m timeit -n 50 -s "$(<ti_setup)" "$(<ti_code_bool)"
