MapCanvas Statusbar

At the bottom of the MapCanvas the MapCanvas Statusbar is displayed. This toolbar displays the current MapCanvas properties:

1. Activated Orbit GIS Function
2. Coordinate Reference System of the MapCanvas
3. Scale
4. Coordinates of the cursor position in the current Coordinate Reference System

Left of the MapCanvas Statusbar, the current activated function on the MapCanvas is shown.
The activated function is also apparent in the appearance of the cursor above the MapCanvas.

A single click on the current Coordinate Reference System (CRS) in the middle of the Statusbar opens the CRS selection window for the MapCanvas.

The CRS of the MapCanvas will by used to interpret every workspace dataset. If a dataset is saved in another CRS, the dataset will by reprojected in the MapCanvas CRS. Orbit supports imagery to be reprojected on the fly. To use imagery such as OpenStreetMap tiles combined with e.g. an Orthophoto aerial picture, just switch it on. The MapCanvas decides the display CRS.

A single click on the current Scale in the middle of the Statusbar opens the pop-up Window Set to Scale.

It is possible to select a preset scale or to enter a random scale.

Remark Unity of Scale
The unity of the scale is linked to the used Coordinate Reference System. There are two distinct types of Coordinate Reference Systems :

• Projected Coordinate Systems : metric scale units
• Spherical Coordinate Systems : scale units in degrees

Remark Scale references of raster datasets
When using digital maps, beware of the data specification towards references of scale. A map created to be used at 1/100.000 can easily be zoomed in to 1/5.000, however lacking precision quality and content relevant for such scale. Be careful when interpreting maps at scales larger than intended by the provider.

A single click on the current Coordinate Reference System Coordinates at the right of the Statusbar opens the Coordinate Display Window.

The Coordinate Display Window shows dynamically the World Geodetic System and the Geographic Coordinates of cursor position.
The Coordinates of the current Coordinate Reference System are shown in the Statusbar itself.
