Scale Bar Main properties Dialog

  • Kies eerst de kaart waar de schaalbalk aan moet worden toegevoegd.

    • Single box and Double box styles, which contain one or two lines of boxes alternating colors.
    • Middle, Up or Down line ticks.

Eenheden en Segmenten

Scale Bar Units and Segments Dialogs

In these two dialogs, you can set how the scale bar will be represented.

  • Select the units you want to use with Scalebar units. There are four possible choices: Map Units, the default one and Meters, Feet or Nautical Miles which may force unit conversions.
  • The Label unit multiplier specifies how many scalebar units per labeled unit. Eg, if your scalebar units are set to “meters”, a multiplier of 1000 will result in the scale bar labels in “kilometers”.
  • The Label for units field defines the text used to describe the units of the scale bar, eg “m” or “km”. This should be matched to reflect the multiplier above.
  • U kunt definiëren hoeveel Segmenten zullen worden getekend aan de linker- en rechterkant van de schaalbalk.

  • You can set how long each segment will be (fixed width), or limit the scale bar size in mm with Fit segment width option. In the latter case, each time the map scale changes, the scale bar is resized (and its label updated) to fit the range set.
