High Resolution 1:10,000 scale Mapping Strategy of Multi ... - NDMA

een prepared scientifically and of very high accuracy at the given scale. The contour
intervals are of 5m or 20m. Neither the scale of the maps not the contour intervals
exactly meets the requirements of disaster management or mitigation. The
requirements of maps for these purposes have been widely discussed in the National
Disaster Management Authority. The Steering Committee and other committees have
dealt this issue at a greater length and considering all types of disasters in the country,
following types of maps have been suggested :
(a) Maps at 1: 10,000 scale with contour interval of 1m for the whole country giving
priority to multiple disaster prone areas; and
(b) Maps at 1:2,000 scale with contour interval of 0.5m for selected areas.
The maps at the scale of 1:10,000 are not only required for disaster management
but for other activities as well. The PC-NNRMS Committee on Cartography of the
Planning Commission has supported mapping at this scale for resource management.
Further, the Ministry of Defence also requires maps at this scale for defence and
security purposes. Survey of India is also planning to introduce a new series of
topographical maps at this scale.
The maps at 1:2,000 scale has been much in demand for urban management
and planning, municipal taxation, JNNURM related activities; and for conducting
elections and censuses. It is to provide a basis for urban flood management and
microzonation. Hence, the maps at both the scales would not only be useful for disaster
management but will also prove to be a national asset.
