How to convert CSV to KMZ with ExpertGPS

How to convert CSV to KMZ with ExpertGPS

KMZ, the compressed version of KML, is a file format that is used by Google Earth and Google Maps for storing placemarks. This type of files is mainly used for distributing information about a specific location, as it can contain geographical coordinates (latitude and longitude), names, 3D model data, or images. CSV is a common format that was designed to help users store tabular data in a plain text form. Normally, the data from the original table is delimited in a CSV file using commas. Therefore, if you have received a CSV file containing geographical data and want to open it with Earth viewers, then turning it into the KMZ format seems a rather good choice. 

For demonstrating the conversion process, I will be using ExpertGPS 5.2 (Shareware $74.95) , because it is a popular application (often referred to in various online discussions and forums) that can help you create KMZ files from CSV. It is also one of the few programs that is capable of completing this process (actually, it is the only tool that I managed to find, excluding online converters).

As you can see, converting CSV files to KMZ format using ExpertGPS 5.2 (Shareware $74.95) can be a bit tricky, but there aren't many alternatives you can choose (most tools can convert CSV files to KML, but not KMZ). If you don't want to use this application and would like to try a different method, then feel free to use any of the available online converter services like Google's Fusion Tables.
