All imported graphics are based on a coordinate system. Site plans are usually stored in a geodetic coordinate system, whereas graphics of floor plans are saved in a local coordinate system. So called calibration points are used to map the graphic to a building in the real world.

Before you can add calibration points to a graphic, they have to be imported.

Different import data channels are available:

  • GPX GIS Calibration Points for GPX files
  • Geographic bookmark file for KML files

Calibration point files can be created for example by using Google Earth. Google Earth requires a fee-based license and generates calibration point files in KML format. The free available tool Graphhopper is not recommended, since calibration points created with Graphhopper are not accurate enough.

In the following the creation of a calibration points file using Google Earth is described.

Uncalibrated Graphics

You can also use graphics without calibration, but this increases the configuration effort elsewhere.

In the Location Tree of the Engineering perspective:

  • You cannot use the Areas > Define Contour or Areas > Define Room Outline functions. That means no room outlines can be created, that are precondition for other functions.
  • You cannot use the Areas > Nest Objects Into Areas by GIS Position function. That means you need to add all objects manually in the Location Tree.
  • You cannot use the Areas > Create Room Viewports + Sequences function. That means, for every area you need to manually create a graphic section and a sequence element annotation that refers to the graphic section.

In the Location Tree of the Access Route Plans perspective:

  • You cannot use the Add Access Path function. That means for every area or detector you need to add a graphical overlay and create an access path manually.

Creating Calibration Points using Google Earth

If GIS coordinates are not available in the floor plan as KML file or cannot be measured, you can generate an own KML file with Google Earth. These KML files may have low precision.
