Lowrance Map File – file format by Lowrance

AT5 (Lowrance Map File) is a file format used by Lowrance fish finders to store map data. It contains detailed information about water depth, bottom contours, and other features, providing anglers with a clear understanding of the underwater terrain.

AT5 File Format Overview

An AT5 file is a proprietary map file format developed by Lowrance, a leading manufacturer of marine electronics. It primarily stores detailed cartographic data, including navigational information, geographical features, depth contours, hazard zones, and points of interest. AT5 files play a crucial role in marine navigation by providing accurate and up-to-date charts for boaters, fishermen, and other mariners.

Key Characteristics of AT5 Files

AT5 files are binary files organized into multiple sections, each containing specific types of data. They typically include vector-based charts with layers of information, such as depth contours, landmasses, and navigation aids. AT5 files also contain metadata, such as the map’s name, coverage area, and version, allowing for easy identification and management. Additionally, they may incorporate raster images or other supplementary data to enhance map visualization. AT5 files are designed to be compatible with Lowrance chartplotters and other marine navigation devices, enabling users to load and display detailed charts for various regions and bodies of water.

About AT5 Files

An AT5 file is a Lowrance Map File used by Lowrance GPS units to store map data. It contains information such as depth contours, navigation aids, and points of interest. AT5 files are typically created using Lowrance’s ChartCreator software.

Opening AT5 Files

To open an AT5 file, you will need to use a mapping software program that supports this file format. Some popular mapping software programs that can open AT5 files include:

  • Lowrance ChartViewer
  • Navionics Boating
  • C-MAP Embark
  • OpenCPN
  • Fugawi Marine ENC Viewer

Once you have installed a mapping software program that supports AT5 files, you can open the file by following these steps:

  1. Launch the mapping software program.
  2. Click on the “File” menu and select “Open”.
  3. Navigate to the location of the AT5 file and select it.
  4. Click on the “Open” button.

The AT5 file will now be loaded into the mapping software program. You can now view the map data and use it for navigation.

AT5 File Characteristics

An AT5 file is a proprietary Lowrance Map File used by Lowrance’s navigation and fishfinding devices. It contains detailed cartographic information, such as contour lines, depth soundings, navigation aids, and other points of interest. AT5 files are typically generated from bathymetric surveys and other data sources and are used to provide accurate and up-to-date navigational information.

These files are designed to be stored on a Lowrance device’s internal memory or on an external memory card. They can be easily transferred between devices using Lowrance’s proprietary software or by connecting the device to a computer. AT5 files are protected against unauthorized access and tampering through encryption and other security measures.
