## 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`
