| Topic | Description |
| Components | The RouteTrak API is comprised of documentation, files, and samples that allow developers to write and distribute applications built on the RouteTrak engine. |
| Getting Started | The RouteTrak API exposes one object, CRTEngine, which is a base class from which one of your applications objects should be derived. |
| Live Vs. Logged Data | Live data refers to the real time data feed coming from a GPS receiver. Logged data refers to the data certain receivers can store in their internal memory, for later use. Either source can be recorded in the log file, but careful consideration should be given to selecting the correct one. |
| Extending the data | The RouteTrak Engine saves GPS information to the log file by default. The application can extend this data with application specific information in the file header section and on a per record basis. |
| Running the sample | The RouteTrak sample application in the \Sample folder demonstrates a simple dialog based application using the RouteTrak API. |
