Oracle Exam 1Z0-770 Topic 9 Question 28 Discussion

A map is a type of component that enables users to view and manage data based on geographic locations. A map consists of a background map and spatial geometry objects that are sourced from data in a table or from a REST data source. Spatial geometry objects are shapes that represent real-world features on a map, such as points, lines, polygons, or heat maps. Three of the supported spatial geometry objects in Oracle APEX are:

Polygons: A polygon is a closed shape that consists of three or more vertices connected by straight line segments. A polygon can represent an area on a map, such as a country, a state, a city, or a building. A polygon can have different colors, patterns, or borders to indicate different attributes or categories of the data.

Heat map: A heat map is a type of visualization that uses color gradients to show the density or intensity of data values in a geographic area. A heat map can represent the distribution or variation of a numeric variable on a map, such as population, income, crime rate, or temperature.

Points: A point is a zero-dimensional shape that represents a single location on a map. A point can have different symbols, sizes, or colors to indicate different attributes or categories of the data. A point can also have a label or a tooltip to display additional information about the data.
