126k Maps of South Asia

<p>A set of about 2,022&nbsp;historical maps of South Asia produced by the Survey of India, at a scale of 2 miles per inch (1:126,720).&nbsp; These maps cover the territory from Eastern Persia (Iran) through present day Afghanistan, Pakistan, India and Burma, and in general were produced during the first half of the 20th century.&nbsp; Each map is a half degree wide by a half degree high, and thus covers the area of one quarter of a 1 degree x 1 degree block.</p> <p>The file naming convention is to first give the <strong><em>number</em></strong> of the 4 degree x 4 degree block followed by the <strong><em>letter (A to P)</em></strong> of the sixteen 1 degree x 1 degree blocks in each 4 degree block, followed by the designation NE, NW, SE or SW to designate one of the four quarters of the one degree block--eg. 38 D SW.&nbsp; This is followed by the name of a town or geographical area encompassed by the map, followed by the <strong><em>date of publication</em></strong> in parenthesis.&nbsp; If a map is reprinted without changes sometime after its initial publication, it is the date of initial publication that is used.</p> <p>An <strong><em>Index Map</em></strong> with the title &quot;0 Topographical Indexes of Survey of India 253k and 126k&quot; showing the sheet numbering system is provided as the first entry in the list of files.&nbsp; This index map can be downloaded to assist in selecting particular maps of interest to the viewer.&nbsp; The maps are then listed in numerical order by sheet number.&nbsp; More than one map will be shown for each geographic block when maps with different publication dates are available.</p> <p>The viewer may find it convenient to use the Search Function (Windows: Ctrl F or Mac: Cmd F) to quickly navigate to a particular map of interest.&nbsp; A click on the &quot;Preview&quot; button will open a preview image, but it will be located at the very top of the file list.&nbsp; A click on the &quot;Download&quot; button will download the map file to the viewer&#39;s computer.&nbsp;</p> <p>The map scans are collected from many sources, and the quality of the scans as well as the underlying paper maps is uneven.&nbsp; Some scans are professionally done, while others are of poor quality.&nbsp; On the assumption that &#39;some map is better than no map,&#39; we include the poor quality scans until a better copy can be obtained.</p>
