1 00:00:02,020 --> 00:00:10,540 Hi again in this video I'm going to show you how to add the elevation values so these ones in here 2 00:00:11,560 --> 00:00:13,950 to the popup window. 3 00:00:13,990 --> 00:00:20,910 Currently, our script simply prints out this string in the pop up window. 4 00:00:21,790 --> 00:00:34,390 So are we going to change and that the way you do that is by first loading the elevation data into a Python 5 00:00:34,390 --> 00:00:36,940 list and then in the loop here 6 00:00:36,970 --> 00:00:50,570 you want to say let's say l in zip(lat, lon, elev) like that here in the pop up argument you 7 00:00:50,640 --> 00:00:53,230 pass the l attribute. 8 00:00:53,290 --> 00:01:03,730 So again we create a list which is named elev, so variable elev, that would be a list of all the elevations 9 00:01:04,150 --> 00:01:09,760 and then we iterate through these three lists. 10 00:01:10,270 --> 00:01:16,930 So lt will get the first item of lat, ln will get the first item of lon, el will get the first 11 00:01:16,930 --> 00:01:22,270 item of elev and those items will be distributed in this function in here. 12 00:01:22,270 --> 00:01:26,790 So lt in here, ln in here, and el in here. 13 00:01:27,100 --> 00:01:35,720 Now I want to save this and execute but I expect to get an error and I want you to see the erro so 14 00:01:35,750 --> 00:01:41,570 that you get familiar with handling errors as well. 15 00:01:41,780 --> 00:01:52,150 So the error is happening on line 14 in this file map1.py which is our file, line 14 16 00:01:52,150 --> 00:01:52,540 is here. 17 00:01:53,590 --> 00:02:03,250 So this is the line and then we have add child pop up. a=As it seems this error has to do with this pop up 18 00:02:04,510 --> 00:02:05,590 object. 19 00:02:05,640 --> 00:02:09,140 I would say this is not a very good error message actually. 20 00:02:09,280 --> 00:02:11,950 It's hard to to read this error and troubleshoot it. 21 00:02:13,060 --> 00:02:16,300 So not very good information given by Folium here. 22 00:02:16,540 --> 00:02:18,550 But anyway uh we have some clues. 23 00:02:18,610 --> 00:02:28,710 So pop up and this says name child get name attribute error numpy.float64 object has no 24 00:02:28,710 --> 00:02:37,140 attribute get_name, so it seems that Folium is trying to apply the get name method 25 00:02:37,630 --> 00:02:43,540 which is a method inside the Folium code base and it's trying to apply it to a number. 26 00:02:43,540 --> 00:02:58,170 So I think that this l here is actually a number and I can check that by saying print type el, save. 27 00:02:58,360 --> 00:03:02,310 Execute the script. 28 00:03:02,560 --> 00:03:03,700 Here is the type. 29 00:03:04,300 --> 00:03:06,200 So this is numpy float 64. 30 00:03:06,230 --> 00:03:11,620 So basically is a float type. 31 00:03:11,660 --> 00:03:14,990 It's actually a special float of the Numpy library, so it's a number. 32 00:03:15,170 --> 00:03:22,580 But anyway you can call it a float so it's a number it's not a string but if you look at help, sorry. 33 00:03:23,360 --> 00:03:29,690 Help(folium.Marker) 34 00:03:30,320 --> 00:03:38,760 you'll see that the pop up parameter expects a string from you as input but you're passing instead you're 35 00:03:38,750 --> 00:03:42,260 passing a float number so you don't want to do that. 36 00:03:42,320 --> 00:03:47,660 What you want to do is to simply convert that float number to a string. 37 00:03:57,150 --> 00:03:59,650 Save the script, go to the terminal, 38 00:04:02,690 --> 00:04:06,520 execute again. 39 00:04:06,560 --> 00:04:09,620 Go to Firefox, reload, 40 00:04:12,790 --> 00:04:18,670 and you get the elevation displayed correctly. 41 00:04:20,990 --> 00:04:22,110 Yeah that's about it. 42 00:04:25,790 --> 00:04:28,270 You can also... 43 00:04:28,400 --> 00:04:38,090 You may also want to stylize what you're displaying, so to add more information there such as 44 00:04:38,720 --> 00:04:39,590 " m" for meters. 45 00:04:43,100 --> 00:04:46,790 So I'm adding the m string to every 46 00:04:49,430 --> 00:04:52,930 pop up window information for all the elevation numbers. 47 00:04:53,030 --> 00:05:00,110 So we're talking about 2447.0 meters, that's elevation of the 48 00:05:00,110 --> 00:05:00,590 volcano. 49 00:05:01,160 --> 00:05:01,600 Yeah. 50 00:05:01,610 --> 00:05:02,330 That is the idea. 51 00:05:04,010 --> 00:05:06,980 I hope this was clear and I'll talk to you later.
