## What is transformation between coordinate systems in computer graphics?

**Geometric Transformation**: The object itself is transformed relative to the coordinate system or background. … Coordinate Transformation: The object is held stationary while the coordinate system is transformed relative to the object. This effect is attained through the application of coordinate transformations.

## What is the purpose of coordinate transformation?

A coordinate transformation **changes point positions from one coordinate system to another**. It does not require the original measurements used to create the coordinates.

## What do you understand by transformation?

A transformation is **a dramatic change in form or appearance**. An important event like getting your driver’s license, going to college, or getting married can cause a transformation in your life.

## What is transformation in computer graphics with example?

Transformation means changing some graphics into something else by applying rules. We can have various types of transformations such as translation, **scaling up or down, rotation, shearing**, etc. When a transformation takes place on a 2D plane, it is called 2D transformation.

## What happens in coordinate transformation?

The **procedure for converting from one coordinate system to another** is known as coordinate transformation. The procedure requires that some points have their coordinates known (or measured) in both the arbitrary and the final coordinate systems. Such points are called control points.

## What does transformation mean in GIS?

The transformation is a calculation to convert the geographic coordinate system of the layers to match the geographic coordinate system of the map as the map draws so that everything is aligned. The data is not changed by a transformation. This real-time translation is sometimes referred to as projecting on the fly.

## What is transformation in GIS?

From wiki.gis.com. A geographic transformation is **a mathematical operation that converts the coordinates of a point in one geographic coordinate system to the coordinates of the same point in another geographic coordinate system**.
