What is demographic data?

Statistically socio-economic information, such as population, income, and education, linked to specific geographic locations.

What are thematic maps?

Maps that show occurrences of phenomena under study, typically revealing patterns that aren't visible just by looking at the landscape.

What is the difference between reference maps and thematic maps?

Reference maps provide basic geographic information, while thematic maps focus on specific patterns or themes.

What are some examples of spatial analysis questions in geography?

Questions about why certain phenomena occur in specific locations and the patterns associated with them.

What is a graphical scale on a map?

A scale displayed in bar format that remains accurate even if the size of the map is changed.

What does 'geo-referencing' mean?

Tying a location to a record in a database or on a photograph.

What is an isoline map?

A map that uses lines to connect points of equal value, such as temperatures on a weather map.

What is a graduated symbol map?

A map that uses varying sizes of symbols to represent the intensity of a phenomenon.

What is the importance of census data?

It systematically acquires information that determines federal resource allocation and congressional representation.

How do businesses utilize GIS?

Businesses use GIS to track assets, monitor locations in real time, and conduct analyses for informed decision-making.
