give the brief function of SDIs
Hi dear,
An SDI comprises the people, policies and technologies necessary to enable the generation and use of spatially referenced data through all levels of government, the private and non-profit sectors and academia. Following are few functions of SDIs:
- Data Publication and search
- metadata Catalog
- Testing of different data collection methods
- main interfaces to find geospatial resources.
- Outreach
- General administration
Good Luck
If you are asking about SDI in technology then here is your answer:
Serial Digital Interface ( SDI ) is a digital video interface that is used for the transmission of uncompressed, unencrypted digital video signals for professional video equipment. Standard SDI cables are terminated with BNC connectors and have a nominal impedance of 75 Ohms.
I would request you to provide the full forms in the question. This will reduce the miscommunication(if any).
I hope my answer helps. Have a great day!
