• Attribute Data: Descriptive information associated with spatial features, stored in databases linked to spatial data.
• Software: Tools and applications used to process and analyze spatial data, such as mapping software.
• Hardware: Computers and devices used to run GIS software and store data.
• People: GIS professionals who analyze data, create maps, and develop applications for various purposes.
• Layers: Different themes of geographic data systematically mapped and maintained.

Common Layers in National Mapping Systems

• Administrative Boundaries: National borders and political divisions.
• Transportation Networks: Roads, highways, railways, and airports.
• Hydrography: Rivers, lakes, and coastlines.
• Topography: Elevation, landforms, and digital elevation models (DEMs).
• Land Use and Land Cover: Residential, commercial, industrial areas, and vegetation types.
• Utilities and Infrastructure: Power lines, water pipelines, and communication infrastructure.
• Cultural and Built Environment: Buildings, monuments, and protected areas.
• Geological and Natural Resources: Fault lines, mineral deposits, and renewable energy sources.
• Population and Demographics: Population density and demographic data.
• Environmental and Ecological Data: Ecoregions and environmental quality monitoring.
