MyGDI Metadata Catalogue
MyGDI Explorer is a metadata catalogue that contains records describing the contents of materials and information on how to access the materials. In other words, it enables users to find the GIS resources, view its description and make assessment on it.
The metadata records in MyGDI Explorer are provided by various data providers with a common objective – to make their resources available to users in Malaysia as well as over the world. It is the linkage that connects the data provider with the users of geospatial information via the internet.
The growing availability of data of all kinds from many different sources has made GIS technology become more useful and widely adopted. Information published in metadata by data providers enables users to search the required data.
Registration for Metadata Publisher
Data providers are required to register here before their metadata can be displayed. Their request to have their metadata displayed can be made known by contacting the MyGeoportal Administration.
Geographic dataset in ISO 191939 XML standard can be uploaded into the system without the need to re-enter their metadata. The metadata will be handled by the software metadata editor.
Users are not required to register with MyGDI Explorer for browsing the site to search for geospatial information . User can click here to browse the site.
Searching for Geospatial Information
MyGDI Explorer’s graphical user interface (GUI) includes a search form for metadata exploration. There are five (5) options available for users to do the search. They are known as search filters as listed below:
· Geographic area of coverage or place name
· Content Types
· Data categories,
· Date (date update or time period)
A search filter or combinations of the filter options would prompt the displaying of metadata associated with it where users can extract the needed information.
When a search query is submitted, user will be presented with a result that contains the title of the geospatial resources (metadata title) together with its geographical extent. The metadata title contains an abstract that describes the resource in general and links to online map.
Map Viewer Application
Map Viewer is an application that integrates raster and vector data in a same interactive platform using services. This application is developed to support MyGDI Explorer in which users will be able to view map services provided if the URL of the map services are included in the metadata. Users will be given opportunity to use some of the map services pre-configured in the application as well as consuming other known services to be overlaid in the application. Users can access this viewer at here. Geospatial information search facilities can be made here.
