Geospatial Data or geographic information is data or information that identifies the geographic location of features and boundaries on earth, such as natural or man-made features, oceans, and more. Spatial data is usually stored as coordinates and topology and can be mapped. Spatial data is often accessed, manipulated or analyzed the Geographic Information Systems (GIS).
Metadata is textual and sometimes graphical information that describes geographic information system (GIS) resources in the same way a card in a library's card catalogue describes a book. Once you've found a resource with a search, its metadata will help you decide whether it's suitable for your purposes. To make this decision, you may need to know how accurate or current the resource is and if there are any restrictions on how it can be used. Metadata can answer these questions.
Malaysia Geospatial Data Infrastructure (MyGDI) is an initiative by the government to develop a geospatial data infrastructure to enhance the awareness about data availability and improve access to geospatial information. This can be fulfilled by facilitating data sharing among participating agencies. MyGDI as the National Spatial Data Infrastructure (NSDI) for Malaysia, is a national infrastructure comprises of person, policy, standard, geospatial information and technology established by MyGDI Circular Letter No. 1 of 2006 - Guidelines for the Implementation of Malaysia Geospatial Data Infrastructure (MyGDI) for the purpose of facilitating the sharing and dissemination of geospatial information amongst government agencies, private sector and the general publics. Through this infrastructure, smart partnership among agencies is continuously being developed to produce and share geospatial information thus providing customer-focused, cost effective and timely delivery of geospatial data.
Geographical Names Database (Pangkalan Data Nama Geografi-PDNG) is like a geographical names data bank which is use to store names, locations, historical backgrounds and gazette notifications.It is an authoritative records that are available for government and public use.
National Spatial Data Infrastructure (NSDI) defined as the technologies, policies and people necessary to promote sharing of geospatial data throughout all levels of government
Map service is a web map service that displays geographic data or information in multiple layers of map images over the Internet. Map service uses a geographic dataset that also includes a combination of different data and parameters to determine and display a more dynamic, interactive and clever map image
MS1759 is a method of encoding features and attributes that facilitates geospatial information structuring. Efficient and systematic sharing requires structured and uniform storage of geospatial information.
MyGDI Data Service is an application that provides information based on 12 categories of geospatial data that is shared and provided by agencies to other Government or Government agencies (G2G) through secure map services using the Government-provided environment.
MyGDI Explorer is an application that provides a catalog of National geospatial information. This application enables users to search, view, review, share and manage geospatial information metadata
