Import Measurement Data from ASCII file

ProMan offers the possibility to import measurement data to do comparisons between predictions and measurements.

Measurement data can be imported from an ASCII file by clicking File > New Measurement File....

After selecting a database to which the measurement should be imported, the ASCII file containing the measurement data has to be selected. As the coordinates used in the ASCII file must match the ones of the selected database, you have the possibility to convert and adjust the coordinates of the ASCII file during import. The data contained in the currently active result view can be deleted before importing the new data by selecting the corresponding option in the lower-left part of the dialog.

In the right part of the dialog the format of the data contained in the ASCII file can be specified. The data to be imported has to be in a tabular format with longitude / latitude coordinates and a corresponding measurement value. The columns to be imported can be specified within the Measurement Import dialog. In case the ASCII file contains a header section, keywords indicating the data section to be imported have to be entitled in the lower-right part of the Measurement Import dialog.

Note: Depending on the resolution of the simulation area, several measurement points might fit into a single raster point of the result file. In this case ProMan takes the average of those measurement points.

For example, if multiple measurement points fall in the same ProMan pixel and the those measurement values are -68 dBm and -72 dBm, the mean value of -70 dBm will be considered and saved in the file with the imported measurements.

The following example shows an ASCII import file with a header section and a keyword for the indication of the data section. The value “N.C.” stands for not computed - this point is left white in the graphical display.
