Suppose I want to display a georeferenced image that is available on a web.
I had already talked about This before, but in this case I want to project a map that is not on my hard drive but online. This is the case of the geological fault map of Honduras, which is available on the website of Dr. Robert S. Rogers.
1. Georeferencing it
First, we downloaded it and placed it on the hard disk.
For this purpose, and since it is a sheet with a scale greater than 1 in one million, georeferencing it to Chilazo It's enough. This is done by importing it as an overlay image and then stretching it until the boundaries match; if you had end coordinates, it would have been more accurate to insert them in lat / lon.
Otherwise, I have arranged an approximate 65% opacity.
Once this is done, it is saved as kml of just 1 kb.
1 Modifying the kml
First, let's see that the kml does not contain the image, but refers to a place where it is stored:
So to create kml files of the other images, you would only have to edit the file with a notepad, changing the address of the local disk for that of the image hosted on the web and the name. Be careful, with the notepad you can edit a kml file, not a kmz because it is a compressed file.
This can also be done from Google Earth, modifying the properties of the layer. See that just by changing the url, for any of the maps available on that website, I can make the display because they were exported in the same layout.
By the way, see now by showing the epicenters of the earthquakes that have occurred since the year 1970.
Here you can See kml Of the example.
