Projecting Data: An Example

This section provides a simple example application illustrating the basic operations that you must perform when using a projection. It shows how to create a projection and compute the image of a geographic point on a flat surface.

This example is composed of the following steps:

• Running the Example Application

• Including the Projection Declaration

• The Main Function

• Initializing a Projection

• Creating the Projected Data

• Projecting the Data

• Printing the Result of the Projection

• Calculating the Inverse Projection

• Printing Geographic Coordinates

• The Complete Example
