Mapping activities in the Census Organization:

The Census Organization of India is one of the largest producers of maps in the country based on census data. Standards of cartographic excellence can be seen in the geographical maps published in the various census reports /disseminating census data and publications of maps. The mapping activities also remained integral part of it. Besides, maps are also published in special reports, monographs and publications prepared at time to time as per requirement. Different type of Administrative and thematic Maps, Atlases and 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.

The State Administrative maps prepared for the census helps in covering all the areas in Uttar Pradesh without any omission and overlapping. Therefore, the organization prepares Administrative unit maps at all levels i.e. State, districts, sub-districts (Tahsil/CD blocks etc.), villages, towns, wards and the enumeration Blocks. .

Two kinds of maps are prepared by the organization.
1. Maps for use in Census (Pre-Census)
2. Maps for use in data dissemination (Post-Census)

Pre-Census Mapping:
Pre-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.

Post-census mapping :
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. Administrative Atlas, Housing Atlas, Census Atlas and Constituencies Atlas of the state and Map profile are some of the prominent decennial publications of the organization. Some of the nail views are given below.

Use of GIS tools:
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. 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.

The Software bases on GIS application was developed and available at the Census of India Website which allows generating thematic maps to analyze Census data, become popular among Government departments, NGOs, Universities, Research Scholars and other data users.
