Note: This page describes an obsolete version of GPSBabel that may substantially differ from the current or development version.

Lowrance USR (lowranceusr)

This format can...

  • read and write waypoints

  • read and write tracks

  • read and write routes

This format has the following options: ignoreicons, writeasicons, merge, break, wversion .

The Lowrance iFinder GPS series has the unique capability within the Lowrance models to output its data to an MMC card. The data is saved to the card as a .USR file and can be read by your computer using a card reader. Waypoints, icons, routes, tracks are supported. Event marker icons contain a symbol, name, latitude and longitude only. By default, Event marker icons are converted to waypoints on read. On write, you are able to create icons from waypoints.

ignoreicons option

Ignore event marker icons on read.

This option instructs GPSBabel to not convert icons to waypoints on input, but to instead disregard them altogether

writeasicons option

Treat waypoints as icons on write.

(USR output) This option converts the waypoint information to an event marker icon.

merge option

(USR output) Merge into one segmented track.

(USR output) This option merges all tracks into a single track with multiple segments.

break option

(USR input) Break segments into separate tracks.

(USR input) Break track segments into separate tracks. file.

wversion option

(USR output) Write version.

Newer (post 2006 or so) Lowrance devices added a version three of their .usr file format that adds depth. Specify "3" here to use that format on write.

gpsbabel ... -o lowranceusr,wversion=2 -F blah.usr is exactly the same as gpsbabel ... -o lowranceusr -F blah.usr

To create a file that contains depth but therefore isn't usable on older Lowrance products, use this: gpsbabel ... -o lowranceusr,wversion=3 -F blah.usr
