Adding new legs coordinate to a survey

[thivageran97]

Hi there, i believe it is possible to add a new leg coordinate/location based on the example you have provided on the pyhelios example 2. I tried running it with my scene and there seem to be an issue. I think in my case when i change the values manually on the xml file and run it works fine but when i try adding the legs there seem to be an issue. would be great if you could help me figure out how i can do if i just want to add legs without parsing any values for the scanner like in the example where some values are parsed for the scanner. Also would like to know what do you mean by altitude on the example is the height of the scanner that you're referring to?
