ABZ and APT redux

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.

Washington meridian(s)

I’ve been doing background research for my new project on geography and Asian American history, which I’m tentatively calling Barred Zones after the “Asiatic Barred Zone” established in 1917. Part of the article/chapter I’m writing involves systems of longitude and latitude—which fascinates my inner geek. While most people associate these systems with geography and think of them as, in a sense, “natural” because they locate places on the Earth, they are actually “social,” produced by people and institutions within specific historical contexts and circumstances, including politics, local, regional, national and international. A nice example demonstrating this point is the Washington meridian and its use in defining state and territorial borders within the United States in the late 19th century.
