As of November 2020, Georeference won’t work anymore because of a changed Application Programming Interface of Google Earth. iNoise 2021 contains an alternate way to import and calibrate background images from Google Earth.

A background image (BMP or JPG) can easily be calibrated. By clicking [Calibrate] a separate view with only the background image will be opened. Then you’ll have 3 options:

• Scale only – enter two points at a known distance from each other.
  You can click on 2 positions on the bitmap and then enter the distance in meters. The distance could for instance be measured with a tool like Google Earth. Then click [OK]
• Scale & position with local coordinates – enter two points with known local coordinates
  You can click on 2 known positions on the bitmap and then enter the X and Y coordinates of the 2 points. Then click [OK]
• Scale & position with GPS coordinates – enter two points with known GPS coordinates
  You can click on 2 known positions on the bitmap and then enter the latitude and longitude coordinates of the 2 points and select the local coordinate and reference system. The latitude and longitude coordinates can be found using Google Earth. Then click [OK]

The scaling information can be saved as a TXT file by clicking [Save settings]. That allows the bitmap file together with the TXT file to be used as correctly scaled bitmaps in other iNoise models.

Note: For using Google Earth images you can enter 2 place marks with known GPS coordinates and then use the ‘Edit | Copy Image’ menu option to copy the image to the clipboard. Then you can paste the image in Paint (or any other graphic tool) and save it as a jpg file. During the calibration of the jpg file you can then use the 2 place marks as the 2 known positions. However be sure that you do not use a tilted view in Google Earth. This means that just before you make a print screen you need to press the key ‘r’ on your keyboard. That is a short cut and will rotate the view to North and return to top view. You can also switch off the automatic tilt option in Google Earth with the menu option ‘Tools | Options | Navigation’.
