I’ve posted about the Asiatic Barred Zone and Asia-Pacific Triangle recently. I’ve also been looking into ways to display them interactively. After a bit of digging, I learned about KML (Keyhole Markup Language), an extension of XML for geographic annotation and visualization that has become the standard for the Open Geospatial Consortium (OGC). I put together a small KML file to display both the ABZ and the APT. I’ve embedded a map view below using the file that allows you to view and interact with it using Google Maps. The file can also be downloaded and used independently with Google Earth.
Unfortunately, Google Maps/Earth only displays contemporary political boundaries in its standard view. I’m looking into finding or develop an overlay that displays political boundaries in the region from 1917-1965. If anyone knows of one or would like to assist, please contact me by e-mail.
