253k/250k Maps of South Asia

A set of approximately 1,900 historical maps of South Asia produced by the Survey of India at a scale of 4 miles per inch (1:253,440) or the modern metric equivalent of 1:250,000. These maps cover the territory from Eastern Persia (Iran) through present day Afghanistan, Pakistan and India and on to Burma, and parts of Western China and Southeast Asia, and were produced during the late 19th and much of the 20th century. The file naming convention is to first give the number of the 4 degree x 4 degree block followed by the letter (A to P) of the sixteen 1 degree x 1 degree blocks in each 4 degree block eg. 38 D. This is followed by the name of a town or geographical area encompassed by the map, followed by the date of publication in parenthesis. If a map is reprinted without changes sometime after its initial publication, it is the date of initial publication that is used. An Index Map with the title "0 Topographical Index of Survey of India 253k and 126k Mar 2022" showing the sheet numbering system is provided as the first entry in the list of files. This index map can be downloaded to assist in selecting particular maps of interest to the viewer. The maps are then listed in numerical order by sheet number. More than one map will be shown for each geographic block when maps with different publication dates are available. The viewer may find it convenient to use the Search Function (Windows: Ctrl-F or Mac: Cmd-F) to open a search window and quickly navigate to a particular map of interest. A click on the "Preview" button will open a preview image, but it will be located at the very top of the file list. A click on the "Download" button will download the map file to the viewer's computer. The map scans are collected from many sources, and the quality of the scans as well as the underlying paper maps is uneven. Some scans are professionally done, while others are of poor quality. On the assumption that 'some map is better than no map,' we include the poor quality scans until a better copy can be obtained. In the time since this first batch of approximately 1800 maps (see the list below) was posted, additional 253k/250k Maps of South Asia have become available. These additional maps are posted on a separate page, and can be reached by clicking the link(s) below. Included in the final set of additional maps is an Index Map showing the total 253k/250k collection. 253k/250k Maps of South Asia--additional 1--20240421
