Import map features from a file

You can import map features like lines, shapes, and places to your map from KML files, spreadsheets and other files.

Import map data to a layer

Make sure your info is one of these file types:

Unzipped KML and KMZ files can be up to 5 MB.

CSV files and Google Sheet files both support WKT geometry format.

Other files can be up to 40 MB.

Unless the file is a photo, the first row should have titles. To import data properly, make sure you have a column with one of the following:

Do not import files with more than 2,000 rows. You can import up to 100 photos at a time.

CSV or Google Sheets support WKT columns named “WKT.”

On your computer, sign in to My Maps.
Open or create a map.
In the map legend, click Add layer.
Give the new layer a name.
Under the new layer, click Import.
Upload the file or photos that have your info. Then click Select.
1. If you use WKT objects, click the checkbox for WKT to choose a column to position your placemark.

Tip: My Maps add map features automatically.

If you can’t import your info correctly:

Check if the file is in the correct format.
Allow https://mymaps.google.com/ to open your Drive. Learn how to allow or block content settings for certain sites in Chrome.
Make sure your column with WKT data is properly labeled as “WKT” only.

KML files may not import all their data. The data includes:

You may have trouble modifying your WKT column after you import it.

WKT columns are geometries on import. They're no longer text-based.
To edit them, you can use the standard geometry editing tools. You can’t edit them in the table editor the same way an address column can.
