Radio Mobile - RF propagation simulation software

Import coverage...

Images that are saved from Radio Mobile are prepared for use in Google Earth. This is done by adding a file to the image that holds the geocoded information of the image for use in Google Earth. The extention for this file is KML.

This how-to describes how to create a coverage map in Radio Mobile and import it for analysis in Google Earth.

Radio Mobile

  1. Create a map of the area of interest using 'Map Properties' or the button: .



  2. Now we have to redraw the current map window with specific settings to enable transparency in Google Earth. Google Earth treats the colour white in a PNG file as transparent and does not display this 'transparent' color. To create a image that has a ahite backgound Contrast and Brightness have to be set to the right values.
    Open 'Picture properties' or use the button:

    Change the values for Contrast to 0% and Brightness to 100%. and clich 'Draw'.



    The result will be a map with white background.

  3. On the white map we will create the analysis as required. This can be any analysis wich Radio Mobile can Perfom: Polar coverage, Cartasian Coverage, Interference coverage, Visual Coverage, etc.
    In our case we have created a polar coverage and displayed the area that meets the minimum criteria red.



  4. Export the map as a picture using 'File > Save picture as' and give it a appropriate name.
    While saving the picture set transparency as white.



  5. Start Google Earth



  6. Locate and load the KML file that is associated with the in step 4 saved picture.



  7. Now the picture with the analysis will be loaded in to Google Earth and the main window will zoom in to the area wich is exported from Radio Mobile.



  8. Ready!
The nice thing about Google Earth that you can look to the world in perspective.
This helps a lot when analysing areas that you have not been your self:
