[GPS] Create a kml file in Python
Overview
Create a ** kml file ** that is 3D geospatial information using Python and display it on Google Earth.
Advance preparation
Since simplekml is required, install the simplekml library according to the OS.
Purpose
To create a kml file from a csv file that summarizes latitude, longitude, and altitude. Since it is xml-based, ElementTree was fine, but when I looked it up, there was a simplekml that could create a kml, so I created a kml file using simplekml.
Source
- The csv reading part has been replaced with a sample array.

ls.style.linestyle.color = linestring[4]
ls.style.linestyle.width = 8

ls.coords = [(float(linestring[1]), float(linestring[2]), float(linestring[3]))]
kml.save('skytree.kml')
Output with Google Earth
Display in point format
Displayed in LINE STRING format
