SURVEY OF INDIA

FUTURE PLANS

Swarna subba raoSURVEYOR GENERAL OF INDIA

SURVEY OF INDIASURVEY OF INDIA, is the national survey and mapping agency of the country under the department of science & technology and is the oldest scientific department of the Govt. of India and was established in 1767.

The Survey of India has played an invaluable role in the saga of India’s nation building. The scientific and development initiatives of the department have played an indispensable pioneering role in understanding country’s priorities in growth and development.

Vision

Survey of India takes a leadership role in providing customer focused, cost effective and timely geospatial data, information and intelligence for meeting the needs of security, sustainable national development and new information markets.

Mission

To create, maintain and make available the National Topographic Database of the country conforming to National Standards

To Promote the use of geospatial knowledge and intelligence through partnerships and other mechanisms by all sections of the society and work towards a knowledge-based society

Mandate• To act as adviser to the Government of India on

all survey matters• Geodetic Surveys including Control Work,

Geophysical Surveys and Tidal Observations• Topographical Surveys and Mapping within India

on different scales• Matters concerning International Boundary• Survey for Developmental Projects• Cantonment, Large Scale City Surveys, Guide

Maps etc• Publication of Geographical Maps and

Aeronautical Charts.• Special Series Maps

Services and Products• Geodetic Survey

– Satellite Geodesy - GPS Observations– Tidal Observations – High Precision Leveling– Geomagnetic Surveys– Gravity Surveys

• Topographic Survey– Topographical Survey on different scales– Large Scale Mapping

• Others– Project Surveys, expeditions etc.

• Topographic Maps

• Special Series Maps

• Guide Maps, Tourist Maps

• Coordinates, BM Heights

• Indian Tide Tables

• Geospatial Digital Data for GIS applications

• Digital Elevation/Terrain Model

• Topographic Mapping on 1:10000 Scale

OBJECTIVE

Creation of National Digital Topographical Database

of India on scale 1:10,000 with contour interval 5 metres in 3 yrs and scaling

upwards to 3m in 5yrs.

NEED FOR 1:10K MAPPING• 1:50,000 scale, it is not possible to depict utility

buildings like hospitals, schools, police stations, post offices etc

• On 1:10,000 scale, all such buildings can be comfortably depicted.

• Microzonation for Disaster Management requires 3D base maps on scale 1:10,000.

• In assessing natural resource endowments, agricultural practices, grazing lands, village forests, which are essential for rural development can be shown on scale 1:10K.

• Defence have also expressed for maps on 1:10K / 5K scale for the whole country.

THE VOLUME OF WORK

The creation of the NTDB on 1:10,000 scale is a mammoth task.

This can be evident from the number sheets required to cover the country.

Taking 3’X3’ coverage for one sheet on scale 1:10,000 we would require about 1,32000 sheets approximately .

INDIAN COASTAL ZONE MANAGEMENT PROJECT

.

ICZM project assumes special significance in the context of climate change since one of the definitive findings of the IPCC relates to the increase in mean sea levels as a result of global warming.

COAL MINES PROJECTDirector Technical (Coal Resources Development), CMPDI, Ranchi

To generate the topographical maps of the 28 major coalfields of the country covering an area of 26414 sq km on 1:5,000 scale with 2 meter contour interval in plains (in case of hilly terrain, contour interval may be 3-5 meter as practicable) in GIS digital format, based on Digital Photogrammetric Techniques using high resolution aerial photography with ground verification.

salient features:

(i) Mapping will carried out in 3 phases.

(ii) Mapping will be carried out @ Rs.36,254 per sq km, this figure has been calculated in SGO.

(iii)The following deliverables will be given:

• Hard copy (3 sets of prints on high quality, non shrinkable paper + 1 set of print on non-tearable, polyester transparency sheet).

• 2 sets of soft copy for each map on CD.
