Mapping activities in the Census Organization:
|
The Census Organization of India is one of the largest
producers of maps in the country. It has nearly 130 years of experience of disseminating
census data and publications of maps. Standards of cartographic excellence can be
seen in the geographical maps published in the census reports of 1872 of North-West
Provinces, Cochin, Bengal and the very excellent volume of maps of different collectorates
of the Bombay Presidency of the same decade, the five taluk maps of Mysore state
published in census report of 1891, maps published in the Encyclopedia Linguistic
Survey of India, the state census reports of 1931, the Special All India Ethnographic
Appendix published in 1933 and the maps included in the District Census Handbooks
of 1951 onwards. A major shift in mapping census data however, was witnessed during
Census of India 1961 when the first Census Atlas of 1961 was published in 1968.
In addition, the state and union territory atlases were also published as a sequel.
The tradition continued in the subsequent censuses also.
The preparation of administrative maps has been part
of Census taking since 1872 when first census was held in India non-synchronously.
Since 1881, synchronous census held throughout the country and continued uninterruptedly.
The Census 2011 will be the fifteenth in the series since beginning and seventh
since Independence. The mapping activities also remained integral part of it.
The administrative maps prepared for the census helps
in covering all the areas in the country without any omission and overlapping. Therefore,
the organization prepares administrative unit maps at all levels i.e. State and
Union territories, districts, sub-districts (Tehsil /Taluk/ CD blocks/Police stations
etc.), villages, towns, wards and the enumeration Blocks.
Two kinds of maps are prepared by the organization.
-
Maps for use in Census (pre-census)
-
Maps for use in data dissemination (post-census)
Census mapping provides an accurate geographic frame
to ensure distinctiveness of units of enumeration. As pre-requisites before census
taking, the jurisdictional boundaries are frozen. Various level of territorial units
according to which census is to be conducted are clearly delineated and their maps
are secured. The maps help to clearly demarcate the boundaries of the country as
well as its division into provincial territories and further sub-division into districts
and down to the smallest enumeration areas of villages and towns. The census organization
make sure that these maps representing the latest position of the administrative
jurisdiction and all changes notified by the State Government in respect of the
clubbing of villages or determination of boundaries of municipalities etc., are
properly accounted for. With the help of these maps the census officers responsible
for enumeration of the territory clearly know the dividing line between his/her
jurisdiction. The purpose is to ascertain that the units of enumeration are not
overlapping and that they are collectively exhaustive. These maps are used in each
phases of census taking, i.e., House listing operation and Population Enumeration.
The post-census mapping includes dissemination of
the census data through thematic maps on various Census themes at State/District/sub-District
or village level allowing proper spatial analysis. These are published in various
map products like Census Atlases and Districts Census Handbooks (DCHB). During each
census, the organization produces more than ten thousand administrative and thematic
maps, which are made available for the user agencies, planners, researchers, students
and policy makers. Census Atlas, Administrative Atlas, Language Atlas, Historical
Atlas of India and of each state and Map profile are some of the prominent decennial
publications of the organization. Some of the nail views are given below.
Besides, maps are also published in special reports,
monographs and publications like Temples of Tamil Nadu. Regional Division of India
at the National and State levels and district maps showing village boundaries is
one of the prestigious product of this organization.
Updating of the GIS tools, which were introduced
and adopted since late 1990’s in the Census Organization, has speeded up the process
and enhanced the quality of the maps. The Census Organization has the capability
and the infrastructure for generating theme based maps using GIS but for use on
the Internet, it was considered important to look for appropriate technology. In
2001, Census GIS India was a step in this direction, which allowed generating thematic
maps based on Census data, on an interactive basis using GIS technology. A software
was developed and available at the Census of India Website which allows generation
of thematic maps based results of 2001 Census, free of cost and has become very
popular among Government departments, NGOs, Universities, Research Scholars and
other data users. This software in a way has de-mystified GIS and has now become
a friendly tool to analyze Census data using GIS technology on the Internet.
