Boundaries: This top layer typically includes political boundaries (like state, county, or city limits), administrative boundaries, and potentially property lines.
Elevation: This layer shows terrain variations, often represented by a Digital Elevation Model (DEM) with color gradients indicating different altitudes. Higher areas are typically depicted in warmer colors and lower areas in cooler colors, or with contour lines.
Geographic names: This layer contains text labels for features such as cities, towns, rivers, mountains, and other points of interest.
Hydrography: This layer represents water features, including rivers, lakes, streams, and other bodies of water, often shown in blue tones.
Land cover: This layer classifies the physical material on the surface of the Earth, such as forests, agricultural land, urban areas, wetlands, and barren land, usually depicted with distinct colors for each category.
Orthophotography (Orthopimagery): This layer consists of aerial or satellite photographs that have been geometrically corrected ("orthorectified") to remove distortions and create a true-to-scale map. It provides a realistic visual context of the landscape.
Structures: This layer indicates man-made constructions like buildings, bridges, and other significant structures, often depicted as polygons or points.
Transportation: This bottom layer illustrates transportation networks, including roads, highways, railways, and potentially airports, typically represented by lines.
