Introduction to Maps - AP Human Geography

A relief map shows the three-dimensional topography of an area. Uses shading, colors, or 3D effects to show terrain elevation.

A cadastral map shows property boundaries and ownership details. Legal mapping tool used in real estate and land management.

A locator map provides a simple overview of a location in relation to a larger area. Helps orient viewers by showing context within a broader geographic area.

A map legend explains the symbols and colors used on the map. Essential reference tool that makes maps interpretable to users.

A system that uses latitude and longitude to specify locations on Earth. Forms a grid system for precise location identification worldwide.

The equal-area projection preserves area. Maintains accurate size relationships between regions despite shape distortion.

The conformal projection preserves shape. Maintains accurate angles and shapes but distorts area measurements.

Map generalization is the process of simplifying details to make a map more readable. Reduces complexity while preserving essential geographic information.

Map distortion refers to the inaccuracies in shape, area, distance, or direction when representing the spherical Earth on a flat map. Unavoidable consequence of projecting a 3D sphere onto a 2D surface.

A choropleth map uses different shades or colors to represent data values across regions. Common thematic mapping technique for displaying statistical data by region.

A compass rose indicates the cardinal directions on a map. Essential navigation tool showing north, south, east, and west directions.

A map grid helps locate specific points on a map using a coordinate system. Creates a reference framework for precise spatial positioning.

GIS stands for Geographic Information System. Digital technology that revolutionized geographic analysis and mapping.

A dot distribution map shows the spatial distribution of a feature. Each dot represents a specific quantity or occurrence of a phenomenon.

The Prime Meridian is the zero-degree longitude line, dividing the eastern and western hemispheres. Reference line at $0°$ longitude passing through Greenwich, England.

Latitude is the angular distance north or south of the equator, measured in degrees. Ranges from $0°$ at equator to $90°$ at the poles.

Longitude is the angular distance east or west of the Prime Meridian, measured in degrees. Ranges from $0°$ to $180°$ east and west of Prime Meridian.

The azimuthal projection minimizes distortion in the polar regions. Projects from a point onto a plane touching the Earth's surface.

An isoline map uses lines to connect points of equal value, such as elevation. Also called contour maps, showing patterns in continuous data.

A relief map shows the three-dimensional topography of an area. Uses shading, colors, or 3D effects to show terrain elevation.

A cadastral map shows property boundaries and ownership details. Legal mapping tool used in real estate and land management.

Map projection is the method of representing the curved surface of the Earth on a flat map. Mathematical transformation necessary for creating flat maps from spherical Earth.

A mental map is an individual's internal representation of a portion of Earth's surface. Cognitive map shaped by personal experience and spatial knowledge.

A large-scale map shows a smaller area with greater detail. Higher resolution allows for more precise geographic analysis.

A small-scale map shows a larger area with less detail. Provides broader geographic context but sacrifices local detail.

A graduated symbol map uses symbols of varying sizes to represent data quantities. Symbol size correlates directly with the magnitude of data values.

A cartogram distorts size to represent data values such as population. Area distortion creates visual emphasis proportional to data importance.

Remote sensing involves collecting data from a distance, typically using satellites. Enables mapping and monitoring of inaccessible or large-scale areas.
