KmzExport - Image to KMZ Export
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

Export the input image in a KMZ product.

Detailed description
--------------------

This application exports the input image in a kmz product that can be display in the Google Earth software. The user can set the size of the product size, a logo and a legend to the product. Furthemore, to obtain a product that fits the relief, a DEM can be used.

Parameters
----------

This section describes in details the parameters available for this application. Table [#]_ presents a summary of these parameters and the parameters keys to be used in command-line and programming languages. Application key is *KmzExport* .

**Input image**: Input image.

**Output .kmz product**: Output Kmz product directory (with .kmz extension).

**Tile Size**: Size of the tiles in the kmz product, in number of pixels (default = 512).

**Image logo**: Path to the image logo to add to the KMZ product.

**Image legend**: Path to the image legend to add to the KMZ product.

**[Elevation management]**: This group of parameters allows managing elevation values. Supported formats are SRTM, DTED or any geotiff. DownloadSRTMTiles application could be a useful tool to list/download tiles related to a product.

- **DEM directory**: This parameter allows selecting a directory containing Digital Elevation Model files. Note that this directory should contain only DEM files. Unexpected behaviour might occurs if other images are found in this directory.
- **Geoid File**: Use a geoid grid to get the height above the ellipsoid in case there is no DEM available, no coverage for some points or pixels with no_data in the DEM tiles. A version of the geoid can be found on the OTB website (http://hg.orfeo-toolbox.org/OTB-Data/raw-file/404aa6e4b3e0/Input/DEM/egm96.grd).
- **Default elevation**: This parameter allows setting the default height above ellipsoid when there is no DEM available, no coverage for some points or pixels with no_data in the DEM tiles, and no geoid file has been set. This is also used by some application as an average elevation value.

**Load otb application from xml file**: Load otb application from xml file.

**Save otb application to xml file**: Save otb application to xml file.



Example
-------

To run this example in command-line, use the following: 
::

	otbcli_KmzExport -in qb_RoadExtract2.tif -out otbKmzExport.kmz -logo otb_big.png

To run this example from Python, use the following code snippet: 

::

	#!/usr/bin/python

	# Import the otb applications package
	import otbApplication

	# The following line creates an instance of the KmzExport application 
	KmzExport = otbApplication.Registry.CreateApplication("KmzExport")

	# The following lines set all the application parameters:
	KmzExport.SetParameterString("in", "qb_RoadExtract2.tif")

	KmzExport.SetParameterString("out", "otbKmzExport.kmz")

	KmzExport.SetParameterString("logo", "otb_big.png")

	# The following line execute the application
	KmzExport.ExecuteAndWriteOutput()
