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!

在 MATLAB Online 中打开

KML_Samples.zip

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
