CSV files format
The plugin works with CSV files. Usually, any spreadsheet software can export its spreadsheets to this format.
Headers
The first line of the spreadsheet must be a header. Instead of containing data, its cells hold the name of the columns' data. The plugin requires the following header (and columns), in that order:
- id_observation: a number representing the row. The first row of data (right below the header) must have the number 1, the next one 2, and so on. A spreadsheet editor like Excel will help you easily fill this column.
- id: a number identifying the radioemitter that was measured. It makes more sense to use different files for different radioemitters, so a file always contains the same value.
- name: the name of that radioemitter.
- date: time when the signal was measured. Example: 23/01/2018 03:48:00.
- lat: latitude (North) of the antenna when measuring.
- lon: longitude (East) of the antenna when measuring.
- azi: angle in [0, 360[ indicating where the signal came from.
- filter: filter level in [0, 10]. A greater value means that if the signal was measured, its emitter was closer.
- power: strength of the signal in [0, 10]. A greater sum with niveau_filtre will produce a shorter line on the map layer, thus indicating a closer emitter.
- comment: any comment you want to associate with the data.
