Hi,

It is possible to extract the coordinates (latitude, longitude, altitude) from a KML (Keyhole Markup Language) file using MATLAB.

You can use the kml2struct file exchange submission to import a Google Earth .kml file of points, lines, polygons, or a combination, as a Matlab struct, compatible with the features provided with the Mapping Toolbox.

You may refer to the following blog on working with KML files within MATLAB

To access the file exchange submission, refer the link below

I hope this helps!

readgeotable support KML files to read. However, in R2024a, it only supports reading the shapes, name, and description of KML files as described in the doc. See its doc for further information.

Read geospatial table from vector data file - MATLAB readgeotable (mathworks.com)

unzip("KML_Samples.zip");
filename = "KML_Samples.kml";
T = readgeotable(filename)

T = 3x3 table
             Shape                     Name                                                     Description                                          
    _______________________    ____________________    ______________________________________________________________________________________________

    (37.4223°N, 122.0822°W)    "Simple placemark"      "Attached to the ground. Intelligently places itself at the height of the underlying terrain."
    (37.4220°N, 122.0841°W)    "Floating placemark"    "Floats a defined distance above the ground."                                                 
    (37.4216°N, 122.0858°W)    "Extruded placemark"    "Tethered to the ground by a customizable "tail""                                             

FYI, the sample KML file is from Google's end (link).
