Definition

Noun: A line on a map or chart that connects points of equal value for a specific quantity, such as pressure, temperature, or elevation. These lines are used to visualize the distribution and gradient of the measured quantity across an area.

Usage

The term "isometric line" is used in scientific and technical fields like meteorology, geography, and physics to describe graphical representations of constant values. - In cartography, an isometric line shows areas of equal elevation. - On a weather map, an isometric line of pressure is called an isobar.

Examples

• Noun:
  • The geologist drew an isometric line to connect all points at 500 meters above sea level.
  • By examining the isometric lines for temperature, we can identify a cold front moving across the region.

Advanced Usage

• "Isometric line chart": A type of graph that uses isometric lines to represent three-dimensional data on a two-dimensional surface, often showing relationships between three variables.
  • The researcher presented the data using an isometric line chart to illustrate the correlation between depth, pressure, and temperature.

Variants and Related Words

• Isopleth (n): A more general term for any line on a map connecting points of equal value. An isometric line is a type of isopleth.
• Contour line (n): A specific type of isometric line used in topography to show elevation.
• Isobar (n): An isometric line connecting points of equal atmospheric pressure.
• Isotherm (n): An isometric line connecting points of equal temperature.
• Isohyet (n): An isometric line connecting points of equal rainfall.

Synonyms

• Isarithm (n): A line on a map connecting points having an equal numerical value.
• Constant-value line (n): A descriptive synonym for an isometric line.

Related Phrases

• "To plot an isometric line": The action of drawing or calculating the path of an isometric line based on data points.

• "Density of isometric lines": Refers to how closely spaced the lines are on a map, indicating a steep gradient in the measured quantity.
