MaCGDI is a centre established by the government to manage and promote the development of Malaysia Geospatial Data Infrastructure (MyGDI) as the National Spatial Data Infrastructure (NSDI). MaCGDI is also responsible for coordinating access and delivery of the geospatial information held by all government agencies. The main role of the centre is to continuously make available and accessible current and accurate geospatial data that promotes a sustainable living environment, economic growth and social progress for public. 

Cartography; a hand-drawn or printed document describing the spatial distribution of geographical features in terms of a recognizable and agreed symbolism. Digital; the collection of digital information about a part of the earth's surface.

[cartography] A map legend is a visual graphic of the symbology used in a map that tells the map reader what the polygons, lines, points or grid cells represents.

The basic system of coordinates used to describe the spatial distribution of elements in a GIS

The reduction needed to display a representation of the Earth's surface on a map. A statement of a measure on the map and the equivalent measure on the Earth's surface, often expressed as a representative fraction of distance, such as 1:24,000 (one unit of distance on the map represents 24,000 of the same units of distance on the Earth). Map scale can also be expressed as a statement of equivalence using different units; for example, 1 inch = 1 mile or 1 inch = 2,000 feet.

A server that accesses spatial information and renders it to the client suitable for display as one or more layers in a map composed of many layers.

[software] MapInfo by Pitney Bowes (founded in 1986) is a GIS location intelligence suite that allows users to manage and create geospatial data create for visualization and export to PDF and various file formats.

A mixture or combination of content, elements, or scripts from multiple sources or websites. For example, one could add schools information from the Department of Education and public transportation routes from MetroGIS to a Google Map.

ISO/TC211
Attribute of a phenomenon, body or substance that may be distinguished qualitatively and determined quantitatively

ISO/TC211
Operations associated to measurements.

a scheme that establishes rules for control of other components of a phenomenon that permit the measurement of one component. In a geographic information system, there are three components: time, space, and attribute.

ISO/TC211
Intersection of an ellipsoid by a plane containing the shortest axis of the ellipsoid.

Metadata is a description about data. It is a structured means of describing the content, sources, condition, quality and other characteristics of a data or information resource. Through metadata, necessary information is readily transferred from data providers to users. MyGDI metadata standard is formatted based on MS ISO 19115 - Metadata Referencing by Coordinates, among which includes: identification, data quality, lineage, spatial data representation, reference system, feature catalogue and distribution.
