The "Index Chart of the Great Trigonometrical Survey of India" is a captivating historical artifact that captures the essence of one of the most ambitious scientific endeavors of the 19th century. Created in 1875 by the Office of the Trigonometrical Survey of India, this map meticulously details the extensive network of trigonometrical stations established across the Indian sub-continent. The Great Trigonometrical Survey, initiated by the East India Company, was a monumental project aimed at mapping the vast and diverse landscapes of India with unparalleled precision. This map stands as a testament to the scientific rigor and dedication of the surveyors who undertook this colossal task over seven decades.

The mapmaker, the Office of the Trigonometrical Survey of India, played a pivotal role in advancing the field of cartography and geodesy. Their work not only involved recording topographical information and land ownership but also included measuring the depths of navigable waters and calculating the heights of the majestic Himalayan summits. The survey's scientific contributions were profound, leading to significant advancements in understanding the Earth's curvature and the heights of some of the world's tallest peaks. This map, therefore, is not just a geographical representation but also a symbol of scientific progress and exploration.

As you explore the map, you'll find a detailed depiction of the Indian sub-continent, including modern-day India, Pakistan, Bangladesh, and parts of surrounding regions. The intricate network of trigonometrical stations is prominently displayed, showcasing the meticulous planning and execution of the survey. The map also highlights significant bodies of water, such as the Bay of Bengal, and the formidable Himalayan mountain range, marked by triangulation points and network lines. These features provide a glimpse into the diverse and complex geography that the surveyors had to navigate and document.

The map also serves as a historical record of the numerous cities and towns that dotted the landscape during the survey period. From bustling metropolises like Mumbai, Delhi, and Kolkata to smaller yet significant towns such as Mysore, Jodhpur, and Ranchi, the map offers a snapshot of the urban centers that played crucial roles in the region's history. Additionally, it includes cities from present-day Bangladesh, Pakistan, and Sri Lanka, reflecting the extensive reach of the survey and the interconnectedness of the sub-continent.

The historical significance of this map extends beyond its geographical details. It represents a period when the British colonial administration sought to exert control and understanding over its vast territories through scientific means. The Great Trigonometrical Survey was not only a tool for governance but also a catalyst for scientific inquiry and discovery. Owning this map is akin to holding a piece of history that encapsulates the spirit of exploration, the pursuit of knowledge, and the intricate beauty of the Indian sub-continent's geography.

This map looks great at every size, but I always recommend going for a larger size if you have space. That way you can easily make out all of the details.

This map looks amazing at sizes all the way up to 50in (125cm). If you are looking for a larger map, please get in touch.

Please note: the labels on this map are hard to read if you order a map that is 16in (40cm) or smaller. The map is still very attractive, but if you would like to read the map easily, please buy a larger size.

The model in the listing images is holding the 16x16in (40x40cm) version of this map.

The fifth listing image shows an example of my map personalisation service.

This map is available as a giclée print on acid free archival matte paper, or you can buy it framed. The frame is a nice, simple black frame that suits most aesthetics. Please get in touch if you'd like a different frame colour or material. My frames are glazed with super-clear museum-grade acrylic (perspex/acrylite), which is significantly less reflective than glass, safer, and will always arrive in perfect condition.

This map is also available as a float framed canvas, sometimes known as a shadow gap framed canvas or canvas floater. The map is printed on artist's cotton canvas and then stretched over a handmade box frame. We then "float" the canvas inside a wooden frame, which is available in a range of colours (black, dark brown, oak, antique gold and white). This is a wonderful way to present a map without glazing in front. See some examples of float framed canvas maps and explore the differences between my different finishes.

For something truly unique, this map is also available in "Unique 3D", our trademarked process that dramatically transforms the map so that it has a wonderful sense of depth. We combine the original map with detailed topography and elevation data, so that mountains and the terrain really "pop". For more info and examples of 3D maps, check my Unique 3D page.

My standard frame is a gallery style black ash hardwood frame. It is simple and quite modern looking. My standard frame is around 20mm (0.8in) wide.

I use super-clear acrylic (perspex/acrylite) for the frame glass. It's lighter and safer than glass - and it looks better, as the reflectivity is lower.

Six standard frame colours are available for free (black, dark brown, dark grey, oak, white and antique gold). Custom framing and mounting/matting is available if you're looking for something else.

Most maps, art and illustrations are also available as a framed canvas. We use matte (not shiny) cotton canvas, stretch it over a sustainably sourced box wood frame, and then 'float' the piece within a wood frame. The end result is quite beautiful, and there's no glazing to get in the way.

All frames are provided "ready to hang", with either a string or brackets on the back. Very large frames will have heavy duty hanging plates and/or a mounting baton. If you have any questions, please get in touch.

See some examples of my framed maps and framed canvas maps.

Alternatively, I can also supply old maps and artwork on canvas, foam board, cotton rag and other materials.

If you want to frame your map or artwork yourself, please read my size guide first.

My maps are extremely high quality reproductions of original maps.

I source original, rare maps from libraries, auction houses and private collections around the world, restore them at my London workshop, and then use specialist giclée inks and printers to create beautiful maps that look even better than the original.

My maps are printed on acid-free archival matte (not glossy) paper that feels very high quality and almost like card. In technical terms the paper weight/thickness is 10mil/200gsm. It's perfect for framing.

I print with Epson ultrachrome giclée UV fade resistant pigment inks - some of the best inks you can find.

I can also make maps on canvas, cotton rag and other exotic materials.

Map ageing

I have been asked hundreds of times over the years by customers if they could buy a map that looks even older.

Well, now you can, by selecting Aged before you add a map to your basket.

All the product photos you see on this page show the map in its Original form. This is what the map looks like today.

If you select Aged, I will age your map by hand, using a special and unique process developed through years of studying old maps, talking to researchers to understand the chemistry of aging paper, and of course... lots of practice!

If you're unsure, stick to the Original colour of the map. If you want something a bit darker and older looking, go for Aged.

See some amazing examples of Aged maps.

If you are not happy with your order for any reason, contact me and I'll get it fixed ASAP, free of charge. Please see my returns and refund policy for more information.
