Through this post I want to introduce an online application to create Google Earth files (kml format) from Excel or CSV files. In a simple format of data in geographic or UTM coordinates may create files of points, polygons or paths (paths) that can be read properly in google earth. The following will show the format must have Excel or CSV file for each case. At the end you will find the link to go to the application.
The maximum file size must be 500 KB. They can have extension xls, xlsx or CSV (Comma Separated only). Data can be enter geographical coordinates or UTM WGS84 Datum only.
Here you can download sample files for this application.
In the next video you can see the use of this web aplication.
