How to open KML files in Google Earth and Google Maps using all available methods

KML (Keyhole Markup Language) files are a fundamental tool for visualizing coordinate-based geospatial information. They are widely used in software such as Google Earth, Google Maps, and GIS applications to display routes, markers, polygons, and other cartographic information. Whether you downloaded a KML file or created one to share geographic information, knowing how to open it correctly in Google Earth or Maps is key.

In this detailed guide, we are going to explain to you How to open KML files in Google Earth, Google Maps, and other related toolsWe've compiled information directly from the best sources, including Google Earth Outreach, Google for Developers, 32Dientes, and Google Earth Studio, so you have a complete and up-to-date overview of all available methods.

What is a KML file and what is it used for?

A KML file is an XML-based file type that contains geospatial data such as points, lines, polygons, or paths. Google developed this format for integration with Google Earth, but It can currently be opened and edited on many other platforms, including Google Maps, QGIS, ArcGIS, and Earth Studio.

How to open a KML file in Google Maps

Google Maps allows you to import and view KML files from its desktop version, something many users aren't familiar with. Here's the complete process:

Step 1: Access Google Maps from your computer

To upload KML files, it is essential to use the desktop browser version. Once inside Google Maps, access the top left side menu.

Step 2: Go to the "Your Sites" section

Within the menu, click "Your sites"From here you can manage all the maps you've previously created or saved.

Step 3: Select the “Maps” tab

At the top of that screen you will see several options. Enter «Maps» to view your custom maps.

Step 4: Create a new map

At the bottom of this section you will see a button that says «Create map»It might go unnoticed, as it's not very visible. Click there to open the Google Maps editor.

Step 5: Import your KML file

Once inside the map, on the left panel there is an option that says "To import"By clicking, you can upload your KML file directly from your computer or simply drag the file onto the screen.

Step 6: Rename the route if you wish

The map will load the contents of the KML file and display it directly on the map. It is recommended rename the file (by default it appears as “Unnamed Map”) for easy identification in the future.

View KML files in Google Earth

Google Earth offers a more complete and feature-rich experience for KML files. Here are the different ways to import these types of files in the desktop version:

Import KML files directly

• Open Google Earth Pro from your computer.
• Go to menu Archive and select Import.
• Select your file with KML (or KMZ) extension and click on OPEN.

Once imported, the information will appear in the dashboard. "Temporary Places/Sites". You can manually move it to "My Places" to save it permanently.

Import GIS data converted into KML

Google Earth also allows you to import GIS (Geographic Information Systems) formats such as Shape files (.shp), MapInfo (.tab), and others through built-in tools.

1. Choose Import from the File menu.
2. Choose the correct file type (.shp, .tab, .tif, etc.).
3. Click on OPEN.
4. If it contains too many items (>2500), you can limit the import to a sample or use all content.

Google Earth will then ask you if you want to create a style templateThis is used to assign colors, labels, and visual styles to imported elements. You can choose labels from existing fields (for example, 'Name') and define unique colors (such as blue for rivers or green for areas).

Saving and regionalizing KML files

Once you've created your style template, you can save it and apply it to other projects. Additionally, Google Earth Pro allows you to regionalize data to improve visual performance with many points:

• Select the “Regionalize” option from the Tools menu.
• Choose the KML file you saved earlier.
• Define an output folder and enable the option to open regionalized files upon completion.

This way, the elements will load progressively depending on the zoom level.

Using KML files in Google Earth Studio

Google Earth Studio It's a tool focused on creating visual animations with maps. Here you can upload KML files from your local drive or Google Drive.

When you import a KML, it is added to the dashboard. Overlays, where you can see all the hierarchical elements in the file. You can easily hide or show each one and also filter them by name. Additionally, KML files are stored in Google Drive so that they can be available from any associated project as long as you use the same account.

Earth Studio supports elements such as:

• Point
• Polygon
• Placemark
• GroundOverlay
• ScreenOverlays
• Network Links

During editing, overlays may shift or take a while to load, but the final rendering will be as visually superior as possible.

Supported GIS tools for converting to KML

If you have data in other formats from GIS software, there are several tools to export it to KML:

• QGIS: Open source GIS software with numerous plugins for exporting to KML.
• ArcGIS (ESRI): Includes tools such as ArcToolbox > Conversion Tools > To KML.
• MapInfo Professional: It has the Google Earth Link Utility plugin.
• ogr2gui: Graphical interface application that allows you to convert various formats to KML.

These tools are especially useful for professionals who work with large volumes of data and need to adapt it for use in Google Earth or Maps.

It can be stated that Opening and working with KML files is easier than it seems If you know the right tools. Both Google Maps and Google Earth offer simple and powerful methods for visualizing routes, areas, or any type of geographic data. If you're into cartography, urban planning, hiking, or just like to keep your routes organized, learning how to manage KML files will open many doors for you. Additionally, free tools like QGIS or Earth Studio further expand the possibilities for professional and educational use.
