Final answer:
GIS layers can store a variety of data types including population distribution, physical geography features, infrastructure details, and cultural and historical site locations, with each layer providing specific insights for decision-making and analysis.
Step-by-step explanation:
Types of Data Stored in a GIS Layer
Geographic Information Science (GIS) is a technology that allows for the storage, analysis, and visualization of geographical data. Here are four examples of types of data that might be stored in a single layer within a GIS:
Population distribution: This layer includes data on the density and distribution of humans across a given area, which is critical for urban planning and market analysis.
Physical geography features: Such data encompasses topographical elements like mountains, rivers, and soil types, which are essential for environmental studies.
Infrastructure: Data on roads, utilities, and buildings are crucial for planning development projects and disaster management.
Cultural and historical sites: This layer contains information about significant historical and cultural locations, aiding in their preservation and study.
GIS software uses these data layers to create comprehensive maps that can help with decision making in various fields, including business, urban planning, environmental management, and cultural preservation.
