Scale of aggregation

local, regional, national, global

Cartographic scale can be presented as

a ratio (e.g., 1:100,000), where 1 unit on the map equals 100,000 of the same units in reality.

data layers

individual sets of spatial information (like roads, cities, or population density) that can be visualized and analyzed on a map, often using Geographic Information Systems (GIS).

Mercator-

 distorts size to preserve shape

Gal Peters-

 distorts shape to preserve size

how are they related?

They are related to each other because the Gall-Peters projection was created to address the severe size distortions in the Mercator projection

Scale of Data Analysis

 refers to the geographical level at which data is examined, ranging from local (neighborhoods, cities) to regional (states, large areas) to national (countries) and global (the entire world) perspectives.

Gis

how spatial referenced data to understand patterns and processes, gis is helpful to a map by organizing and managing spatial information and patterns.
