NSDI Facilitates
• To reduce the difficulties in accessing datasets (metadata at all levels)
• Helps to develop the datasets with uniform projections and scales
• Improve the standards in representation of different spatial objects.
• Facilitates to integrate the different datasets (maps, satellite images, aerial photographs, databases)
• Fill the data gaps (both spatial and temporal).
• Improve the consistency in datasets to provide the seamless databases.
• Reduce the restrictions in data access.

DATA EXCHANGE- STNADARDS
• Automatic exchange of data sets amongst different
systems necessitating defining and using
standards. Standards are the crux of the NSDI.
• It is necessary to standardize data exchange
formats, networks, communication equipment, and
software interfaces, etc.
• There is a need to standardize the content of the
NSDI nodes, database design and creation
processes, network protocols, and exchange/
transfer of spatial data sets.
NSDINSDI--1010
Purpose of the Data Content Document
It contains the proposal of "Data Specifications" for description and scope
of spatial data themes.
•To provide common definitions for geo-spatial information found in public
records, which will facilitate the effective use, understanding, and
automation of business processes.
•To standardize attributes, which will enhance data sharing.
•To resolve discrepancies related to the use of homonyms and synonyms
in the datasets of various organizations/agencies, which will minimize
duplication within and among them.
•To provide guidance and direction for geo-spatial professionals on
standardized attributes and definitions to improve the standards in data
creation and management.
•To use participatory involvement in the standard development to reach
out to various organizations to encourage application of the standards.
NSDINSDI--1010
THE NSDI STANDARD
• Under NSDI framework major efforts are on in
standardizing data content and schemas, designing and
processing, network protocols, exchange and transfer data.
• The standardization will enable “user transparency” to
information access.
• The NSDI standard would have to be developed and should
cover:
• Content standardization
• Design and process standardization
• Network protocols standards
• Exchange and transfer standard
• NSDI Quality standards
NSDINSDI--1010
NSDINSDI--1010
Scope of Data Standard Document
This deliverable identifies definitions and scope of spatial data
themes. For each spatial data themes, the document provides:
•Definition – brief explanation
•Description – explains the spatial data theme in more detail
•Scope, Use examples - Provide prominent use examples, which
are in compliance to National policies.
•Important feature types and attributes – this is a non-exhaustive
list of the most prominent feature types and attributes.
•Overlaps and links with other themes - known overlap with
and/or dependencies from other spatial data themes.
Soils- Metadata
NSDINSDI--1010
Metadata: One of three
components of geospatial data
• Where: spatial - location
and relationships
(coordinates, topology)
• What: attributes -
descriptive info about
geographic features in
database
• metadata: description of
geospatial data is
incomplete without it!
NSDINSDI--1010
THE NSDI METADATA
Metadata helps people who use geospatial data find the data
they need and determine how best to use it.
The Major elements of Metadata:
• Identification information
• Data quality information
• Spatial reference information
• Entity and attribute information
• Distribution information
• Metadata reference information
NSDINSDI--1010
METADATA STANDARDS
• Data Identification Information
• Contact Information
• Coverage
• Geographic location of the
database (by four coordinates or

NSDI SERVERS ARCHITECTURE
The NSDI have network of Servers to enable the successful
performance of NSDI goals and objectives.
•NSDI Web-Server: The NSDI Web-Server would be the front-end
interface to NSDI. The Web-Server would provide the open access
to NSDI information and ‘secure’ entry to NSDI Metadata and
NSDIAgency Servers.
•NSDI Metadata Server: The NSDI Metadata Server would maintain
the NSDI metadata content. At a higher level, it would be linked to
NSDI Web-Server and lower-level it would be linked through NSDI
Server Catalogue to NSDIAgency Servers.
•NSDIAgency Server: The NSDIAgency Server (or Servers) would
hold the actual spatial data of the NSDIAgency.
