Situation

Location of a place relative to its surrounding environment

Absolute distance

Exact and precise using miles, kilometers, feet

Relative distance

Connections, contacts, movement, and flow of things between places

Distance decay

The interaction between two places declines as the distance between the two places increase

Time space compression

The increasing senses of accessibility and connecting which seems to brings humans in distance places closer together

Longitude

How far east or west a place is on earth

Robinson projection

has slight disortion but is used to compromise

Mercator

Direction,shape, used for navigation and preserves angles of latitude and longitude ( distortion near the poles and increased size of high latitude)

Peters equal area

Area of land,asses are accurate, repositions many countries to their rightful size ( vertically stretched near equator )

Choropleth

Map that uses colors for a specific spatial data

Dot density

Each dot references a specified quantity of a spatial characteristic

Cartograph

Creation of maps

graduated symbol

Use symbols of different sizes to indicate different amounts of a variable

Isoline

Lines that connect point of equal value to depict variation ( weather )

Census

an official count of people in a defined area, such as a state ( US census is every 10 years )

Significance of the u.s census and how we use it in community

The us census count every person living in the country every 10 years. We use it to decide how seats in the u.s House of Representatives and the electoral college are split amount states
