Its members are from [[Survey of India Service]] cadre of [[Civil Services of India]] and Army Officers from the [[Indian Army Corps of Engineers]]. It is headed by the [[Surveyor General of India]]. At present, Survey of India is headed by Lt Gen Girish Kumar, VSM.

"First modern scientific survey of India" was undertaken by W. Mather in 1793&ndash;96 on instructions of Superintendent of Salem and Baramahal, Col. Alexander Read. The present [[Dharmapuri district]], [[Krishnagiri district]] and [[North Arcot]] in western [[Tamil Nadu]] were then called Baramahal.<ref name=si3>Baramahal records Vol.I P.220, In Letter Dated 04.10.1797 The British Government appreciated Col. Alexander Read.</ref> [[Great Trigonometrical Survey]] (1802&ndash;1852) was started by British surveyor Col. [[William Lambton]] on 10 April 1802 from [[St. Thomas Mount]] in [[Chennai]] to [[Indian Himalayan Region|foothills of Himalayas]]. 36 inch huge half ton weight [[Theodolite]] was used, which took 57 days to measure the 12-km base line. This 5-decade project was completed under Survey General [[George Everest|Lt. George Everest]] in the year 1852. Pioneering mathematician and Surveyor [[Radhanath Sikdar]] measured [[Mount Everest]] in 1852, with a height of 29,002&nbsp;feet. Modern measurements indicate the height is 29,037&nbsp;feet. This is regarded as the beginning of a new age of systematic topographical mapping in India succeeding the classical age, and the founding of one of the oldest survey and mapping agencies in the world".. ==Organisation== The Survey of India, headquartered at [[Dehra Dun]], has 18 Geo Spatial divisions ranging from the prediction of [[tide]]s to [[aerial survey]]. It has 23 Geo-spatial Data Centers spread across India, each catering to the respective administrative area. Surveyors are the back bone of Survey of India. Appointments to Group 'A' Civil Stream posts in the Junior Time Scale (Dy Supdtg Surveyor) in Survey of India are made on the basis of competitive [[Indian Engineering Services]] examination conducted by the [[Union Public Service Commission]] and also through permanent secondment of Army Officers [[Defence Stream]] by the [[Union Public Service Commission]]. The important posts/ grades in Survey of India are in the following order of seniority: [[Draftsman]], [[Plane Tabler]], [[Survey Assistant]], [[Surveying|Surveyor]], [[Officer Surveyor]], [[Deputy Superintending Surveyor]], [[Superintending Surveyor]], [[Superintending Surveyor]] (Non-Functional Second Grade)/Deputy Director, Director/Deputy Surveyor General, Additional Surveyor General, [[Surveyor General]]. ==Responsibilities== * '''Advisor to Govt:''' Survey of India acts as adviser to the Government of India on all [[cartography of India]] related matters, such as [[geodesy]], [[photogrammetry]], [[Cartography|mapping]] and [[Cartography#Map symbology|map reproduction]]. * '''Geo names:''' Survey of India is responsible for the [[naming convention]] and spellings of names of [[Geography of India|geographical features of India]]. * '''Certification and publication:''' Scrutiny and certification of external boundaries of India and Coastline on maps published by the other agencies including private publishers. Publication of [[tide table]]s (one year in advance) and maps of India. * '''Surveys:''' [[geodetic datum]], [[geodetic control network]], [[Topographic map|topographical control]], [[geophysical survey]]s, [[cadastral surveying]], [[geologic map]]s, [[aeronautical chart]]s within India, such as for forests, army cantonments, large scale cities, guide maps, developmental or conservation projects, etc. * '''National borders:''' Demarcation of the [[:Category:Borders of India|borders]] and [[Exclusive economic zone#India|external boundaries]] of India as well as advice on the demarcation of inter-state boundaries. * '''Oceanic tidal prediction:''' Undertake prediction of [[tide]]s at [[Ports in India|44 ports]] including [[List of countries with overseas military bases#India|14 foreign ports]]. * '''Research and development:''' In the area of [[photogrammetry]], cartography, geodesy, topographical surveys and indigenisation of technology. * '''Training:''' Training for the central and state government departments as well as from foreign countries. ==Maps== Survey of India publishes maps and the unrestricted category maps can be obtained at very affordable prices from its several Geo-spatial data centers. Restricted category maps require due approval from government authorities. Many other rules govern the sale and use of Survey of India maps. Only an Indian citizen may purchase [[topographic map]]s and these may not be exported from India for any reason.{{Citation needed|date=December 2011}} ==Gallery== {{Gallery |title= |width=160 | height=120 |align=center |footer= |File:SurveyOfIndia.png |alt1= |Old logo of the Survey of India |File:Radhanath_Sikdar.jpg |alt2=S |[[Radhanath Sikdar]], a mathematician who first calculated the height of [[Mount Everest]] in 1852. |File:William_Lambton.jpg |alt3= |[[William Lambton]] (1753 &ndash; 19 January 1823) started [[Great Trigonometrical Survey]] (1802&ndash;1852). }} ==See also== * [[Indian Institute of Surveying & Mapping]] (IIS&M) * [[Survey of India Service]] * [[Cartography of India]] * [[Linguistic Survey of India]] ==References== {{Reflist}} * Reginald Henry Phillimore, ''Historical Records of the Survey of India,'' 5 vols.
