Map Maker

With this free web app you can create a downloadable map with locations and flows between locations - helpful for analyzing your supply chain.
You can (un)hide customers/warehouses/plants/suppliers/flows separately via the layer control in the upper right corner of the map.

  • Latitude, Longitude is the result of converting a textual address into geographic coordinates,
    a process called geocoding. You can use:
  • Size (locations) and Quantity (flows) are numeric values.
  • Type (optional) can be set to C, W, P, or S (Customer, Warehouse, Plant, or Supplier).
    If not specified, then C is used as default type.
  • Each location type has its own shape and color.
    Generic C/W/P/S colors can be adjusted via Map Settings (found directly below the map).
  • Color (optional) contains a color code (see color picker below)
    If this field is specified, then it overrides the generic C/W/P/S colors.
  • Pick color →     Color =
