Meteosat Images are generally imported as images in _\[filename\].png_ format. The Meteosat images constitute a time series of png images, that are geo-referenced by means of a specific world file. Each image needs its own world file, which in case of PNG carries the extension _\[filename\].pgw_ .
Import of images in another format, such as JPEG is also possible. The corresponding world file for a JPEG file has the extension _\[filename\].jpg_ .
The images are imported via a common time series import, for which a specific image parameter needs to be specified in a _parameterGroup_ via the parameter id _image_ . |

The value resolution indicates the resolution of the values of the pixels (grey tones) in the Meteosat images. In this case 8 grey tones are resampled into a single grey tone for storage space reductions. In the module for the timemeseries import run for a Meteosat image the import is then configured as follows:
