Pai Bridge

The bridge over the River Pai is often cited as the most conspicuous evidence of the presence of the Imperial Japanese Army
in Thailand during WWII. Unfortunately the statement is in error, as is much other information about that period . . . .

Text Notes

This page discusses World War II aerial photos taken by the Royal Air Force (RAF) and provided on-line by the Geo-spatial Digital Archive Project (GDAP) in its Williams-Hunt Aerial Photograph Digital Collection.[2a]


The Williams-Hunt collection has two separate sets of aerial photos for Mae Chan:[3]

In the following, aerial photos were joined into mosaics using Microsoft ICE (Image Composition Editor) as much as possible.


Photomosaic No. 1

The area around Mae Chan outlined above in red was recorded in seven RAF aerial photos taken on 05 October 1944:[4]

3.^ "Terrain" map from  Nations Online Project: Searchable Map and Satellite View of Thailand using Google Earth Data. Annotation (red & blue colored items) placed with PhotoShop by author.

 

 

4.^ Photos were assembled using Microsoft ICE (Image Composition Editor) as much as possible. Order of assembly was important: images 02501-02503 and 02505-02507 were assembled first and then joined. 02504 had to be manually added to the resulting composite because it did not sufficiently overlap with the other photos for the ICE program to stitch them together.

Mosaic has been oriented so that its north is to the top of the page.
