The Lost Maps of Nagaland

Posted by Dave Smith On 9/10/2008 06:58:00 PM 0 comments


The Times of India brings a story, speaking to the necessity of preserving maps and records dealing with boundaries - apparently the official maps depicting the boundary of the Indian state of Nagaland have gone completely missing.

Nagaland is a hill state in the foothills of the Himalayas, located in the far northeast of India, adjoining the Indian states of Assam, Arunachal Pradesh and Manipur, and bordering Myanmar (formerly Burma) to the east.

From the article,



The government has lost all "original documents" — comprising details of boundaries — of Nagaland, in a glaring instance of callous handling of vital public documents.

The Union home ministry and the Assam government, which originally kept the records of Nagaland, do not even have the valid "map" of the state which ironically is in the throes of violence sparked by the demand to carve out Greater Nagaland by extending the existing boundaries of the state.

The matter came as a shock to home ministry officials when it was brought to light for the first time by Nagaland during its submission before the Local Commission on the Assam-Nagaland Border here last week.

In response to the commission's direction to submit before it the original documents of the state to settle boundary disputes, Nagaland said it was not in a position to give the written statement unless "its original documents which were purportedly lost by Assam" were returned.
At present, it looks like some of the details of the boundary will have to be recreated from surveys and whatever remaining documentation can be salvaged. The region has not been without its share of historic boundary disputes.

Get It Surveyed?

I was amazed to see the articles in the news about the border fence debacle, where construction evidently went full-tilt along the US-Mexico border to construct a fence to prevent illegal immigration, following 120-year-old barbed wire strands, and without any apparent proper surveying research, and construction stakeout.


Evidently there are legal monuments spaced along the border, tall metal or concrete markers managed by the International Boundary and Water Commission, jointly operated by the US and Mexican government, but in constructing the fence, they evidently failed to do their due dilligence, and in fact the fence was revealed to be encroaching into Mexican territory. Certainly historic fence lines can have some meaning and significance as boundary evidence and as lines of possession in certain circumstances, but in this circumstance, particularly where an international boundary is concerned, I am frankly disturbed that proper survey work went by the wayside.

Time to add GPS to the Swiss Army Knife?

Associated Press is carrying the story about an accidental incursion of 170 Swiss infantry troops, as they strayed across an unmarked border into neighboring Liechtenstein. Fortunately these countries are generally on friendly terms, and in fact, according to the CIA World Factbook, Switzerland is responsible for the military defense of Liechtenstein; however these types of incidents illustrate how easy diplomatic snafus can happen...

It's also particularly ironic given the investments that the Swiss have made in quality geospatial products. Google Earth blog recently reported on getting imagery for the entire country of Switzerland at 50cm and many Swiss cities at 25cm, as well as improvements to the DTM models, with the entire country of Switzerland terrain at 10m resolution, and the Swiss Alps now high-res.
