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

Step 1: Prepare your info

Import a file

Make sure your info is one of these file types:

  • CSV
  • TSV
  • KML
  • KMZ
  • GPX
  • XLSX
  • Google Sheet
  • One or more photos in Google Drive or Google Photos

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:

  • Latitude-longitude information
  • Addresses
  • Place names
  • WKT-formatted vector geometry objects

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.”

Step 2: Import info into the map
  1. On your computer, sign in to My Maps.
  2. Open or create a map.
  3. In the map legend, click Add layer.
  4. Give the new layer a name.
  5. Under the new layer, click Import.
  6. 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.

Learn about importing or modifying info problems

If you can’t import your info correctly:

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

  • Info balloons with HTML or JavaScript
  • KML tours
  • Time-based elements
  • Image and screen overlays
  • MultiGeometries
  • 3D models
  • Folders

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.
