Reason for ChartBundler

  • Lets talk a bit about amounts here and not low stress or high stress. Using the charts offline on a mobile device. Lets say the display is about 1024x1024 Pixel, then we will need at least 16 tiles per map. If we start on zoom level 8 with the bounding box and continue to zoom level 16 for the harbours, we need around 2 Mio tiles. This 16 tiles on zoom level 8 is about the northern Adria. If we want the Channel just skipping Lands End up to the belgian coast, this would be 6 by 5 on zoom level 8.
  • Hi Alexej, do not understand this paragraph!? 2 test datasets of mine:
    • INT-1463 bei zoom-level 13 (s="53.7" n="54.25" w="7.4" e="9.05"):
      x: 37
      y: 21
      total: 777
