Facilitating spatial data,
NSDI way |

Greater
sharing and better access
to high quality geographic
data could better business
opportunities, improve
decision-making based
on sound scientific information
leading to sustainable
development. This critical
need to find better ways
for finding and sharing
geographic data led to
the evolution of national
spatial data infrastructures
world wide. |

All government organisations –
central, state or local–require
geographic information to manage
land, coordinate disaster relief,
plan/manage infrastructure facilities
and solve environmental and social
issues. Private companies too require
geographic information for facilities
management, resource location and
marketing. Computers have made geographical
information of the world and its
inhabitants more accessible and
useful to governments, businesses
and communities to take critical
decisions. Maps that were once confined
to paper have increasingly migrated
to digital form. Geographic information
systems (GIS) allow users to integrate,
analyse and manage information about
locations in ways that was never
possible before. Improvements in
software, increased storage capacity
and plummeting hardware costs put
geographic information systems and
associated technologies on desktops
everywhere.
Geographic data collection is a
multi-billion business. But many-a-time,
data gets duplicated as organisations
and companies tend to collect data
over the same piece of land for
their projects/plans either due
to ignorance about the data availability,
inaccessibility of data or difficulties
in sharing the available data. Data
created for one application may
not be easily translated for use
into another application. The problems
are not just technical but the lack
of culture in organisations/institutions
to work together and share information/data.
Central or state government organisations,
creators of geographical data, may
not be willing to share the same
with each other, with local governments,
private companies or general public.
If sharing data among organisations
were easier, millions could be saved
annually and governments and businesses
could become more efficient and
effective.
While organisations like Survey
of India and Geological Survey of
India have public access to geographic
information as a mandate, this has
for long been limited to only a
small part of the actual data generated.
Though the scenario is slightly
encouraging after the liberalisation
of policy guiding maps in the country,
current approaches suffer from invisibility.
In an ocean of unrelated and poorly
organised digital flotsam, the occasional
site offering valuable geographic
data to the public cannot easily
be found.
