How to use

Plotting GPS data of a data set

Once a data set has been loaded, its GPS data can be plotted by clicking the Read/Plot button.

Each GPS data point is plotted as a small rectangle.

Once the plotting finishes, a message is displayed in the notification with the number of data points plotted.

Furthermore, the range of latitude and longitude of the GPS data is displayed on the plot.

Displaying a GPS data point's information

When the GPS data finished plotting, clicking on a point on the plot will display its data in the notification box.

Exporting the GPS data

By clicking the Export button, the GPS data will be exported to a file. The name of the exported file is the name of the data set suffixed with .gps.dat. By default, the file will be in the same directory as the data set. A sample directory structure is given below.

Data/
├─ data.data/
└─ data.data.gps.dat

The directory the export file is stored in can be changed by clicking on the Export Directory button.
