5.2.9.2 Map calibration
To create your own map you will need a digitized map or picture with orthogonal projection in one of the
following pixel graphics formats.
png Portable Network Graphics
bmp Windows Bitmap
dib Device Independent Bitmap
gif Graphics Interchange Format
jpg/jpeg Jpeg File Interchange Format
pcx PC Paintbrush
tif Tag Image File Format
If your map is not in one of the above formats, you can simply convert it in one of the supported formats by
a third party program.
To use a map in u-center, three calibration points are needed. For these points you have to know the pixel
coordinates and the according WGS84 coordinates in the latitude/longitude format in degrees (longitude: -180.0°
to 180.0°, latitude: -90.0° to 90.0°). These points are stored in the map calibration file. The calibration file must
be stored at the same location as the bitmap itself. It has the same name but a different extension (*.mcf). The
format of the calibration file is very simple and can be edited in a simple editor like notepad.
5.2.9.2.1 Example
As an example we will have a look at the virtual map file world.png and its calibration file world.mcf.
