Convert OVL to TRK

Understanding OVL and TRK file formats

OVL files are commonly used as overlay files in mapping and navigation software, such as OziExplorer. They typically store graphical overlays, routes, waypoints, or map annotations that are displayed on top of base maps. TRK files, on the other hand, are track files that contain GPS track data—sequences of recorded positions, timestamps, and sometimes additional metadata. TRK files are widely used for sharing and analyzing GPS tracks in various navigation and mapping applications.

Why convert OVL to TRK?

Converting an OVL file to a TRK file is useful when you want to extract route or track information from overlays and use it in GPS devices or software that supports the TRK format. This is especially helpful for outdoor activities like hiking, biking, or off-road navigation where track data is essential.

How to convert OVL to TRK

Direct conversion from OVL to TRK is not always straightforward, as OVL files may contain more than just track data. However, if your OVL file contains route or track overlays, you can use mapping software to export this data as a TRK file.

Recommended software for OVL to TRK conversion

OziExplorer is the best software for handling OVL and TRK files. Follow these steps:

1. Open OziExplorer and load your map.
2. Use File → Load → Map Overlay File (OVL) to import your OVL file.
3. Once the overlay is loaded, select the track or route you wish to export.
4. Go to File → Save → Save Track File and choose the TRK format.

If you do not have OziExplorer, you may try GPSBabel, a free tool that supports a wide range of GPS file formats. However, GPSBabel's support for OVL files is limited, so OziExplorer remains the most reliable option.

Tips for successful conversion

• Ensure your OVL file contains track or route data, not just map annotations.
• After conversion, verify the TRK file by loading it into your GPS device or compatible software.
• Keep backup copies of your original OVL files in case you need to repeat the process.

Summary

Converting OVL overlay files to TRK track files is best accomplished using OziExplorer. This allows you to extract and use GPS track data from overlays for navigation and analysis in a wide range of GPS applications.
