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.

  • Google Earth has been installed.
  1. In the Search field, enter the address of the component to be configured.
  1. Click Search or press Enter.
  1. Right-click My Places and select Add > Folder.
  1. Click the icon with the yellow Pin (+).
  1. Select a corner of the building.
  1. In the New Placemark dialog box, enter a unique name. This name is displayed in Siveillance Control as calibration point name. Since graphics are not always properly rotated, preferentially use descriptive names such as directions.
  1. Click OK.
  1. Add the other corners of the building.
  1. Right-click the folder you have added and select Save Place As.
  1. Select a folder, a file name and the file type KML.
  1. Click Save.
  • The KML file is saved and can be imported in Siveillance Control.

Importing Calibration Points

  • The Engineering perspective is displayed.
  • A file with calibration points either in GPX or KML format is available.
  1. Click  Import Data.
  1. You have the following options:
  • If you want to import a GPX file, select GPX GIS Calibration Points in the Data channel field.
  • If you want to import a KML file, select Geographic bookmark file in the Data channel field.
  1. Click Next.
  1. Select the file you want to import.
  1. Click Next.
  1. In the MOX Detail Change dialog box, select the advanced import settings. For more information refer to: Advanced Import Settings.
  1. Click Next.
  1. In the Importer Settings dialog box, select the import settings. For more information refer to: Import Settings.
  1. Click Finish.

Calibrating Graphics by Inserting Calibration Points

  • The Engineering perspective is displayed.
  • The Graphics Tree is displayed.
  • The graphic you want to calibrate has been imported.
  1. Double-click a graphic.
  1. Zoom in the upper left corner of the graphic. The higher the zoom factor the more accurate you can place the calibration point.
  1. Open the Calibration Points node and select the calibration point for the upper left corner.
  1. Drag the calibration point to the respective position in the graphic.
  1. Place at least two further calibration points in the corresponding corners of the building.
  1. Make sure that no calibration point is placed twice. Otherwise, the calibration is not calculated.
  1. In the Graphics view, select the assigned calibration points.
  1. Right-click one of the highlighted calibration points and select Recalibrate graphic as floor Plan (2D).
  1. Enter the height specifications, for example 0 for a graphic displaying the first floor or 1 for a graphic displaying the second floor. Keep in mind to add the height in meter for each floor for buildings with more than one floor.
  1. To reset all objects of the graphic to their respective GIS location, mark the Reposition objects already shown check box.
  • In the Graphics view, the calibration points are displayed as circles with a cross in the center.
  • In the info line, the GIS coordinates are displayed.
  • In the toolbar, the zoom factor is replaced by a scale.
