Metadata provides complete description about spatial data. The main component of the SDI is metadata. Each dataset contains separate metadata set. Metadata basically describes,

• extent of dataset
• quality
• original data sources
• formats
• applicable scales
• year of production/ update
• coordinate system
• map projection
• reference systems
• attributes
• accessibility….. and many more

 

Publishing metadata helps to
• Avoid duplication by allowing users and producers to find required spatial information
• Trace existing and more appropriate datasets
• Protect in the event of misuse or unauthorized use of datasets.

This enables users and producers to access, visualize and evaluate metadata and geospatial information online from anywhere and at anytime and make assessment on it.

Searching for Spatial Information and viewing results

There are many options for users to do the search. They can search for metadata using theme, producer, nearest city, format and date. Searched results will be displayed for all appropriate datasets. Users can view metadata as well as spatial data with attributes of searched results.

Searched results are not limited to spatial data, but it also provides information about data producers.

Users are not required to register with SDI for browsing the site to search for spatial information.

Registration as a Metadata Publisher

Data producers are required to register with SDI to upload their metadata. Registration is free and will be done by administration of SDI. Registered data producers can update existing metadata and add metadata for new datasets online.
