Head of Coordination section for GIS Users Councils,
Department of GIS, National Cartographic Center (NCC) of IRAN, Tehran, IRAN
The goal of NCC Iran is to reduce duplication of effort among agencies, improve quality and reduce costs related to geographic information, to make geographic data more accessible to the public. Much has been accomplished in recent years to further the implementation of the NSDI
The concept of a Spatial Data Infrastructure (SDI) has emerged globally to facilitate the transit of spatial infor-mation from data producers to a vast and ever-growing community of users. An SDI encompasses the policies, technologies, standards and human resources necessary for the effective collection, management, access, delivery and utilization of spatial data for a specific jurisdiction or community. The best use of geospatial data, which is being produced more every day for sustainable development, requires some infrastructure, which facilitates search, query, access, share and use of the data. Such an infrastructure is called SDI, which ranges from local, provincial, national, and regional to global levels. Fundamental in making decision is existence of accurate and up to date information. This information can be optimized applied in sustainable development if it has spatial infrastructure. Applying operational methods in gaining sustainable development goals and it technology is possible by encouraged. Required infrastructures are of the important information is spatial information and especially national spatial information.
Spatial Data Infrastructure (SDI)
Many of National and Regional SDIs in world, describe common components as bellow:
- Institutional Framework
- Technical Standards
- Fundamental Datasets
- Existing Models
Objectives in Developing an SDI
There are a number of other objectives that should be considered when developing an SDI:
- Produce Standardized fundamental spatial datasets
- Avoid unnecessary duplication of cost in developing and maintaining those data
- Facilitate access to and application of those data
- Enable integration of other application specific data by all users.
Society improvement is possible if influence of development progress is sustainable. We need executive sustainable development program to have it in different part of society and it can be done if we consider economical and social and political factors in our decision.
IT Position in NSDI
We can see an overview in Fig 1. The main point of this diagram is it position and effective factors on it that cause IT modern concept by putting strategies and policies in spatial data infrastructure.
