I'm trying to represent in QGIS a flow map (time series) for a CSV file which contains the following info:

  1. field_1 = the number of the trip
  2. field_2 = Date of the trip
  3. field_3 = (morning) time interval
  4. field_4 = latitude of the Orig_X (Primary Origin)
  5. field_5 = longitude of the Orig_X (Primary Origin)
  6. field_7 = starting time from Orig_X (Start of the Trip)
  7. field_9 = latitude of the Destination_Y1 (First destination)
  8. field_10= longitude of the Destination_Y1 (First destination)
  9. field_11= time of arrival in Destination_Y1

10.field_12= latitude of the Destination_Y2 (Second destination)

11.field_13= longitude of the Destination_Y2 (First destination)

12.field_14= time of arrival in Destination_Y2

13.field_17= total time of the flow for the distance Orig_X to Destination_Y1 + Destination_Y2

I would like to have a map showing the flows between OriginX to Destination Y1+Y2. The map should show, depending on the total distance which varies daily, different flows from the minimum 9 minutes to the maximum of 37 minutes.

I'm attaching a sample of the CSV file from the QGIS sessioncsv_file.

    Welcome to GIS SE. As a new user, please take the Tour. Attaching an image of ASCII data isn't nearly as useful as including the data itself (or a reasonably scaled subset thereof). Commented Jan 11 at 14:47

    You say: "The map should show, depending on distance, different flows" - what does that mean? How should it be shown? Commented Jan 11 at 15:25
  • Different flow because on the same distance are different times of travel. Commented Jan 11 at 16:41
