Exporting Data

Maps produced by ReefMaster are not suitable for navigation, and should never be used for navigation.


Map projects, tracks and waypoints can be exported in a range of formats, for use on GPS devices or in other GIS applications:


Export Format


CSV (Comma Separated Values)

CSV is a simple text file format that contains a list of positions and depths, in the format Latitude, Longitude, Depth.

The CSV export format can be used to export map contour data and tracks, and is useful for transferring track-point data between ReefMaster projects or other GIS applications.

GPX (GPs eXchange)

The GPX format is an XML based format that can be used to export tracks, waypoints and map contours. The GPX format is compatible with a wide range of GPS devices and GIS applications, and is particularly useful for transferring waypoints to Lowrance™ and Humminbird™ units.


Waypoints, tracks and map contours can be exported in the native Humminbird™ waypoints and routes file format (.HWR) and track format (.HT). Map contours are exported as tracks, with each separate contour being written as a separate track "segment". Contour maps can be viewed on Humminbird GPS devices by styling the imported track as a solid line.


The AT5 format is a fully featured map format compatible with Lowrance™ and Simrad™ GPS units. The AT5 format can be used when exporting ReefMaster map projects and is the recommended export format for all Lowrance™ and Simrad™ devices.

Google Earth

Map projects, tracks and waypoints can be exported to the Google Earth file format, which can be viewed in Google Earth and a wide range of other GIS applications.

ESRI Shapefile

The Shapefile format is widely used across GIS applications, and can be used to export map projects, tracks and waypoints. Shapefile is the recommended export format when using ReefMaster data in other GIS applications. The Shapefile format is also used by the Navico Insight Map Creator (IMC).

Image File

Map projects and sidescan mosaics can be exported as high resolution png image files.


Map projects and sidescan mosaics can be exported in the MBTiles tiled image database format, which provides a high resolution export that can be used within ReefMaster and in an ever increasing number of other GIS applications.
