INTViewer provides many features off-the-shelf, but its extensibility is unique. Developers can customize numerous aspects of INTViewer by extending the INTViewer platform. And one way to extend this platform is to write Java plugins.
Sometimes, you don’t need to add new features to make a software great — just revisiting a design can add value. For INTViewer, the CRS selection dialog is one of the areas we improved just by tweaking the design.
