NSDI characteristics
•The objective of SDI is to maximize the use of GI )access to GI provided by different organizations(
•SDI needs coordinated action on the part of governments and organizations
•The primary purpose of SDI is to support decision making
•SDI involves a wide range of activities )technical, institutional, financial and human resources(

How the spatial decision is made?
Acts (laws) are controlling the decision making process
everywhere

NSDI positive effects
• Geo-Information policy• Establishing Unified low level standards for
HW, network,..• Establishing Unified high level standards for
DB design, data exchange, metadata…• Avoiding data monopoly

• Establishing a collaborative strategy and a collaborative policy for Data collection, data base administration
• Avoiding data redundancy through cooperative coordinated data collection and data entry
• Publishing detailed information (metadata) about the existing data for organizations, researchers, and public

•Main portal connects all organizations
•Some organizations participating in this portal have
working agreements to share data for city projects
•others have developed web services for analyzing

Where should we locate the school?
•At least 150 meters from major roads (to avoid noise and accidents).
•Within 500 meters of the nearest residential area (to keep students
in a reasonable walking distance).
•Within 200 meter of the city park (so student can have their break in the park)
•Within 500 meter of the city public library (to encourage students for research)
•At least 1000 meters from the industrial zone of the city (to avoid noise)
•The area should be at least 15000 square meters
•Provided with utilities
•The area should form a rectangle with longer distance facing the north direction.

Before NSDI After NSDI
Decision making and time line
Data redundancy Coordinated data collection projects
Conflict in updating data Coordinated updating process
Few agreements for data exchange Perfect data exchange through the IT Policy
Individual analysis (point of view) Collaborative analysis
More time for data collection More time for data analysis & modeling
Slow methods for data exchange Speed exchange through networks
Time and money Saving time and money (1:7)
Data ownership Data ownership and benefits for others Through specialized portals & web services
