Hi,welcome to solsarin site,today we want to talk about“difference between kml and kmz”,

thank you for choosing us.

difference between kml and kmz

The difference between KML and kmz is that the kml is the files that are not in the zipped format, whereas the kmz is the file that has the files in the zipped format.Importantly, the kml is the file format in which the general pictures of the geographical locations are stored,

whereas the kmz needs less storage and can store the detailed geographical location of the place. Due to the zipped format of the kmz, these files took less time to share big files as compared to the kml.

The kml is the abbreviation of the Keyhole Markup Language. it was first given bg the Keyhole, but in 2004,

it was bought by the goggle. The kml is the file format that stores the geographical locations of the earth. They can analyze and store both two-dimensional maps and as well the three-dimensional data of the satellites. it files are usually large and require more storage if the detailed geographical image is being stored.

The kmz is the abbreviation of the Keyhole Markup Language zipped. it is nothing but the kml files stored in the zipped format. The kmz is also used to store the geographical locations of the earth. These files format are mainly used to store large kml files in zipped, which compresses them without losing the quality, and these extensions are also used to share these larger files across the internet.

KML stands for Keyhole Markup Language. It was developed by Keyhole Inc. for their Keyhole Earth Viewer. A basic KML file is an XML file with specific notation for expressing geographical information such as annotations and visualizations in 2D and 3D geographical models available online.

Keyhole Inc. was acquired by Google in 2004 and Google products such as Google Earth and Google Maps were upgraded to support KML. KML was adopted as an international standard at the Open Geospatial Consortium in 2008.

kml files store geospatial data, and files provide information to the relevant software regarding the features such as place marks, images, polygons, 3D models, and textual descriptions. These features are always incorporated with a specific coordinate on the map, often given by longitude and latitude. These files are also used to record the user interaction with features of the map for later use.

Basic KML Documents

The simplest kind of KML documents are those that can be authored directly in Google Earth—that is, you don’t need to edit or create any KML in a text editor. Placemarks, ground overlays, paths, and polygons can all be authored directly in Google Earth.

When to Use the KMZ File Format?

Here are some general tips on when you might want to use KML instead of KMZ and vice versa. Note that these are guidelines, and you’re free to choose the approach that best suits your needs

Why share GIS data as KML?

KML is an excellent format for sharing geographic data with a wide audience because:

Publish your content as a KMZ file.

When you’re ready to distribute your content to others – whether you’re posting a file on the web, emailing an attachment to a colleague, or preparing for a presentation in front of a live audience – save your KML file and any images you want to include as a KMZ file.

When you make a KMZ file, you don’t have to include images. A KMZ file can simply be a compressed version of a KML file without any multimedia files included. At the very least, you’ll make a smaller file that will download faster.

How do I view a KML file?

If you have a KML file from previous versions of Google Earth, you can view it in Google Earth for web browsers.

  1. moreover, using the web browser on your computer, open Google Earth.
  2. On the left, click Projects .
  3. Click the New Project button.
  4. Select the KML file you’d like to view.

How do I create a KML file in Google Maps?

To create a KML file from your spreadsheet data, just follow the steps below:

  1. Go to
  2. Paste your data into the big box.
  3. Click “Map Now”
  4. Wait for geocoding to finish, then click “Continue / Save”
  5. Fill out the title, description, and make sure to include your email address, then click “Save Map”

Supported KML elements

Elements in a KML file are supported by ArcGIS Pro and are reflected in the Contents pane and in the display of a KML layer. Supported elements include the following:

  • 3D models
  • Custom data
  • Ground overlays
  • Network links
  • Placemarks
  • Regions
  • Screen overlays
  • Time spans
  • Time stamps

A Placemark is one of the most commonly used features in Google Earth. moreover, it marks a position on the Earth’s surface, using a yellow pushpin as the icon. The simplest Placemark includes only a <Point> element, which specifies the location of the Placemark.moreover, You can specify a name and a custom icon for the Placemark, and you can also add other geometry elements to it.

As a result, open the KML Samples file in Google Earth and expand the Placemarks subfolder. This folder includes three different types of placemark: simple, floating, and extruded.

A KMZ file consists of a main KML file and zero or more supporting files that are packaged using a Zip utility into one unit, called an

archive. The KMZ file can then be stored and emailed as a single entity. A NetworkLink can fetch a KMZ file from a web server. When the KMZ file is unzipped, the main .kml file and its supporting files are

separated into their original formats and directory structure, with their original filenames and extensions. moreover, In addition to being an archive format, the Zip format is also compressed, so an archive can include only a single large KML file. moreover, depending on the content of the KML file, this process typically results in 10:1 compression. Your 10 Kbyte KML file can be served with a 1 Kbyte KMZ file.

Google Earth and Google Maps can read KML and KMZ files directly, and they can save files as KMZ files. By default, the main KML file is named doc.kml.

You should create a KMZ file if your doc.kml file is larger than 10 Kbytes, or if the doc.kml files references other files (images, sound files, models, textures).

How do I convert a KMZ file to Google Maps?

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

  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. Choose or upload the file or photos containing your info, then click Select.
  7. Map features are added automatically.

What software opens KMZ files?

What is Google Earth KMZ?

What Is a KMZ File? KMZ files are very similar to ZIP files. They allow you to package multiple files together, and they compress the contents to make downloading faster. moreover, This allows you to bundle images along with your KML file if you want.

What are KMZ files used for?

A KMZ file is a placemark file used in Google Earth and Google Earth Pro. Since KMZ files contain latitude and longitude coordinates, as

well as 3D model data, they can be used in GIS environments to digitally represent real locations of the Earth.

Is KML or KMZ better?

A KMZ file combines the images with the KML into a single zipped file. KMZ files are better because the lossless compression decreases file sizes, although only slightly, and because they make it impossible to separate and lose required image files. Even if someone tells you they want a KML file, you should send a KMZ.9 oct. 2019

What is the difference between KMZ and KML files?

KML is the file extension for an unzipped file, while KMZ is the zipped version of a KML file. 3.
