“Security
concerns about maps”
I agree with Lt Gen Ranjit Singh that “Security
concerns about maps are at times overplayed”
in India (Coordinates, Vol II, Issue 1 January
2006) and commend him for his candid position.
But, I may add that in India this concern
is put forward all the time. With experience
of working with 100+ countries around the
world, I never witnessed anything like India.
And, taking the recent city map of Delhi
as an example, which shows airport area(s)
blank, I wonder what is being protected
in the days of high- resolution imagery
and GPS positioning. I have seen a GPS surveying
report of an airport in India with station
coordinates printed in arc seconds up to
three decimal places. But, the degrees and
minutes omitted. If this policy is for security,
it would take only a few seconds with a
handheld GPS receiver to get the “omitted”
information.
About 20 years back, one of my ex- SOI colleagues,
who was visiting USA, told me that he would
like buy a 1: 24,000 map for taking to India.
I said that you do not have to buy and I
can provide you as many as you want as they
are openly available. These days, one can
download them from the website.
In the same context, I have been informed
many times that India wants to retain the
old 19th century Indian Datum, with obsolete
defi nition and very poor accuracy, for
security. It is surprising how SOI is overplaying
the security concern and thus, trying to
hide behind a “porous” geodetic
legacy. This datum would only jeopardize
the national interest and 21st century “Good
Coordinates”.
