Question

the suitable contour interval for a map with scale 1:10000​

Answer 1

scale : 1:10000 i.e ,

1cm in map = 10000cm in plan

now also 1 cm in map =10000cm or 0.1km inplan

also 10cm in map = 1km

i.e no of cm per km = 10

now we know from formulae contour interval (C.I)m=( 20/ (no of cm per km ))m

=20/10

=2m
