# distortcalc

Distortion parameters for map projections

## Syntax

## Description

`[`

calculates the area scale, the maximum angular deformation, the maximum and minimum
particular scale distortions, the particular scale along the meridian, and the particular
scale along the parallel using any combinations of input arguments from previous
syntaxes.`areascale`

## More About

## Algorithms

The

`distortcalc`

function uses a first difference technique.The function calculates the distortion parameters by slightly perturbing the input point locations in different directions and then projecting them.

The results can contain a small amount of imprecision due to the function numerically computing derivatives.
