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

MAPPING REQUIREMENT FOR EARTHQUAKE HAZARD
ZONATION
1. High resolution satellite imaginary (0.6 meter or better resolution) to be used
to derive 1:10,000 map and 1-meter contour map for Zone-V and Zone-IV.
2. Aerial mapping using laser and medium format digital cameras at the scale of
1:2,000 or better with three dimensional maps of all the towns falling in Zone
V and Zone IV with complete asset mapping. The data model given in
Annexure to be used to delineate all the assets and critical structures with
attributes.
3. The ground survey using vehicle mounted mobile survey system to be used to
create high resolution maps of the narrow streets and lanes in the town.
4. All critical facilities and approach roads to be marked clearly in the map for
mitigation purpose.
5. Geotectonic maps in the scale 1:50,000 are required for hazard zonation.
6. Geotechnical maps in the scale of 1:10,000 will be required in the specific
areas and towns where Microzonation for earthquake hazard needs to be
done.
7. All the maps must follow standard guidelines laid down under National
Mapping Policy.
