将数据导入 Google 地球

1.  On your computer, open <a href="https://earth.google.com/">Google Earth</a>.
2.  At the bottom left on the home screen, click **Open local KML editor**.
3.  Click **Open KML from device**.
4.  Select the KML file you want to open.

After you select the file you want to open, any changes must be explicitly saved
or downloaded back to your computer's file system to avoid losing work. Autosave
is supported only on Chromium-based desktop browsers.

Note: You can open local KML files in Google Earth even if you're not signed in.

To go to the home screen, click Earth <img src="/maps/documentation/earth/images/earth-logo.png" class="inline-icon" alt="Google Earth
logo">.

## Import other file formats {:#import_other_file_formats}

Google Earth for web and mobile primarily supports KML, KMZ, GeoJSON, and
Shapefile (`.zip`) for direct import.

For [CSV and Google Sheets files](#import-csv-and-google-sheets-files),
Google Earth supports direct import as a data layer with automatic location
detection. For other vector or raster formats (for example, GPX), you can
convert these files to KML or CSV. Once converted to KML, you can import them
into Google Earth.

[Learn how to use KML
features](https://developers.google.com/kml/documentation/).

If you are moving from Google Earth Pro (Desktop) to the web version, you can
bring your "My Places" data with you.

### Prepare your data for migration {:#prepare_your_data_for_migration}

Before importing, you must export your data from Google Earth Pro:

1.  Open **Google Earth Pro** on your computer.
1.  In the "Places" panel on the left, right-click on **My Places** or a
    specific folder.
1.  Select **Save Place As...**.
1.  Save the file as a `.kmz` or `.kml` to your computer.

If you cannot open Google Earth Pro or need to find the raw source files
(typically named `myplaces.kml`), they are stored in the following directories.

Note: These folders are often hidden by default.

#### Windows {:#windows}

Copy and paste the following path into your File Explorer address bar:
`%USERPROFILE%\AppData\Local\Google\GoogleEarth`.

Tip: If you are navigating manually, you may need to enable "Hidden items" under
the View tab in File Explorer to see the `AppData` folder.

#### macOS {:#macos}

Open Finder, press **Command** + **Shift** + **G**, and paste this path:
`~/Library/Application Support/Google Earth`.

What to look for:

-   `myplaces.kml`: This is your current, live data.
-   `myplaces.backup.kml`: A backup created the last time you launched the app.
-   `myplaces.kml.tmp`: A temporary file created during a session.

### Import capabilities and limitations {:#import_capabilities_and_limitations}

When migrating "My Places," your choice of import method depends on the
complexity of your data. For a detailed breakdown of supported KML elements,
refer to the [Google Earth KML Import
Guide](https://support.google.com/earth/community-guide/307322063/google-earth-kml-import-guide).

-   **Feature Counts**: If you intend to import your data as project features
    (allowing you to edit icons, lines, and shapes), there is a limit of
    approximately 10,000 features or 250,000 vertices per project. If an import
    exceeds these limits, Google Earth will automatically attempt to import your
    data as a read-only data layer instead.
-   **Large "My Places" Files**: For Google Earth Pro on desktop users that have
    "My Places" files that exceed 10,000 features or contain several megabytes
    of data we recommend you:
    -   **Split your data**: Divide your "My Places" into smaller, thematic
        folders in Earth Pro and save each as a separate `.kmz` file.
    -   **Import as Data Layers**: If you have tens of thousands of points and
        don't need to edit them individually, use the **Import as a data layer**
        option.
-   **Copy and Paste**: You can also copy individual features or folders from
    Google Earth Pro and paste them directly into a Google Earth project. Simply
    select the feature in the desktop version, right-click to Copy (**Ctrl** +
    **C** or **Cmd** + **C**), go to your Google Earth browser tab, and Paste
    (**Ctrl** + **V** or **Cmd** + **V**) while a project is open.

## Other viewing options {:#other_viewing_options}

For temporary, local-only access, you can also open your KML files directly in
Google Earth on web through the local KML editor experience.

Note: This mode does not support cloud storage or advanced project features.

To see data from multiple projects on the map at once, you can use the
[reference projects](https://medium.com/google-earth/enhancing-project-management-in-google-earth-a-guide-to-the-latest-updates-ad096c34d239)
feature.
