A map showing the triangles and transects used in the Great Trigonometrical Survey (1802–1852), produced in 1870. Surveyor-General of India George Everest (b.1790-d.1866) under whom GTS was completed and Mount Everest was named in his honour.
Joseph E. Schwartzberg (2008) proposes that the Bronze Age Indus Valley civilization (c. 2500–1900 BCE) may have known "cartographic activity" based on a number of excavated surveying instruments and measuring rods and that the use of large scale constructional plans, cosmological drawings, and cartographic material was known in India with some regularity since the Vedic period (1st ...
In 1875, the decision was taken that the Survey budget should be reduced from 240,000 to 200,000 pounds. This resulted in a reorganization under Surveyor-General Colonel J.T. Walker to amalgamate the Great Trigonometrical, Topographical and Revenue Surveys into the Survey of India. [9] Survey towers used by George Everest to elevate the instruments
Mairie de Loevenich (), from the Topographic Survey of the Rhineland by Tranchot/Müffling, sheet 57 (published 1806/07).. A map series is a group of topographic or thematic charts or maps usually having the same scale and cartographic specifications, and with each sheet appropriately identified by its publisher as belonging to the same series.
A topographic survey is typically based upon a systematic observation and published as a map series, made up of two or more map sheets that combine to form the whole map. A topographic map series uses a common specification that includes the range of cartographic symbols employed, as well as a standard geodetic framework that defines the map ...
Lieutenant-Colonel William Lambton FRS (c. 1753 – 20 or 26 [1] January 1823 [2]) was a British soldier, surveyor, and geographer who began a triangulation survey in 1800-1802 that was later called the Great Trigonometrical Survey of India. His initial survey was to measure the length of a degree of an arc of the meridian so as to establish ...
Scope – NPOV maps related to India (post-1947) and historical pre-Independence India (includes the South Asian nations of Pakistan, Bangladesh, Sri Lanka, Nepal and Bhutan). The secondary goal would be to get NPOV maps for Pakistan, PRC, Afghanistan and Bhutan since they border disputed territories of India.
He has been called the "father of Indian geology." He made one of the first [1] geological maps in India covering the Hyderabad region that he travelled through as the geologist of the Great Trigonometrical Survey of India. The map was submitted to the Asiatic Society of Bengal in Calcutta on 8 August 1821 but no copy of it remains.
