![]() # LABELING #REMOVE LABEL for num, annot in enumerate(anotation_list): append(flight_data) #STORE OPERATOR DATA INTO LIST Op_list = #OPERATOR LIST for num,flight_data in enumerate(js_str): Because of that, the labeling code will be included in the update function. In each response the operator data will be extracted and store to that list. To do that we need initiate a list that will be used to to store operator data. To get operator data we can use "Op" key. For example we want to give aircraft's operator label. Therefore in this section we will give a label to those red dots. Just seeing dots without knowing what it is exactly is not so meaningful. If the code is running, you should get a live tracking flight in red dots as in animated picture below. FuncAnimation(fig, update,interval =1000, blit = False) addheaders = įor num,flight_data in enumerate(js_str):Īnim = animation. add_image(osm_tiles, 13) #Zoom Level 13 #PLOT JFK INTL AIRPORTĪx. Import cartopy.crs as ccrs from cartopy.io.img_tiles import OSMĪx =plt. Import urllib.request import json import matplotlib.pyplot as plt from matplotlib import animation This is the complete code up to this step. To make it happen can be done with the animation class from matplotlib. Each response will be parsed and the position will be updated. So in every second we will get new response. To update the aircraft's position the request will be sent every one second. Later the aircraft's position will be plotted on the OSM using the latitude and longitude list. But firstly an empty latitude and longitude list must be created, which will be used to dump each latitude and longitude. To extract the latitude and longitude of each aircraft can be done through a looping in the response JSON list. The complete description can be found at ADS-B Exchange Datafields. More keys are available in the JSON response as you can see above, which contains some information about the flight such as Op for aircraft's operator, Spd: the ground speed in knots, Mdl: Aircraft's model, Man: Aircraft's manufacture, etc. The coordinate can be extracted from the JSON with Lat and Long key. Coordinate in latitude and longitude are the most important thing, because we need them to plot aircraft's position on the OSM map. We already get the response and the next step is to parse it to take some required data. At the end we will get a simple live flight tracking The position will be updatedĮvery one second. The center of the map willīe a location like an airport, and we will request all aircraft in a In this tutorial we will plot aircraft position based on geographicĬoordinate on Open Street Map (OSM) basemap. Days of effort and frustration have been paid, and I'd like to share the result with you. I was thinking how they can do it? This question encouraged me to take a quite long journey till I can write this post. I was so amazed to see some flight tracking website that show hundreds of aircraft around the globe. Knowing something live out there is always amazing, it just like having sixth sense to know something which is not directly in front of our eyes, like a position of an aircraft in the sky, but we truly believe it is somewhere over there. This tutorial will take you to a journey to create a simple flight tracking with python. ![]()
