Table 3.2 : Information required for GIS database for disaster management
Databases at various scales and accuracy will be required for the various
activities related to disaster management. A three-tier database is envisaged for
India.
TIER 1
TIER 2
TIER 3
A regional level database at 1:50,000 scale developed from IRS LISS
images and 1:50,000 scale Survey of India toposheets
A district level database at 1:10,000 scale developed from Quickbird
imagery (0.6m accuracy)
A site-level investigation or micro level database of 1:2,000 scale and
lesser for all the town/cities falling under the major disaster prone/multi
disaster prone districts developed from aerial photography and ground
survey.
Table 3.3 : Three tier GIS database for disaster management
For Tier 1, the Survey of India topographical sheets are useful. However, a few
additional features would be required for NDMA purposes. Regarding Tier 2, the
present DPR is being prepared. Further for the last tier, another DPR is also being
prepared.
The site investigation scale GIS is used in the planning and design of
engineering structures such as building, bridges, roads etc. It is also used on
detailed engineering measures to mitigate natural hazards. Nearly all the data is
