DecisionViewer OCX is an ActiveX OCX control that allows you to embed maps in your own applications. The gecko! Web Server application uses the same graphics engine that the OCX exposes to your applications.

DecisionViewer OCX is supplied without runtime royalties. This means that after purchasing the software developer's kit (SDK), you are free to distribute as many copies of the OCX as you choose to without any additional cost. The SDK is supplied with code examples for Microsoft Visual Basic and Borland Delphi.

DecisionViewer OCX has advanced features for use for example in vehicle or mobile phone tracking, allowing you to track cell phones or vehicles dynamically on your maps with a minimum of programming effort.

The demonstration version you download off this site is limited. It will prompt you for a registration code, and when you have obtained one, it will randomly draw features with a different style, or omit these features from the map. It will also fill in demonstration text in certain instances.
