Swarna subba rao
SURVEYOR GENERAL OF INDIA
SURVEY 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

• 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 PROJECT
Director 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
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.
