Hello,
I can produce you the kml integrating the entire file into one kml, this project was what I did recently which marks my first review on this platform, trust me if you need samples I will provide it, I can perform this task within a day using my Arcmap software, I study surveying and geoinformatics as a course and am a CAD drafter and GIS expert analyst using Autodesk Software and ESRI software, if am taken for this job I will also explain how the task was achieved, looking forward to your response soon. Thanks
Best regards
Samuel
