.GMAP File Extension
What is an GMAP file?
The .GMAP file extension is associated with a specific type of file format that is primarily used in the realm of digital mapping and Geographic Information Systems (GIS).
These files are integral to various applications that require detailed geographical maps. The .GMAP file extension stands for ‘Garmin Map,’ and as the name suggests, it’s closely linked with Garmin devices, a popular brand in the GPS and navigation sector.
More Information.
Garmin introduced the .GMAP file format to enhance the user experience by providing detailed and reliable map data.
The purpose of the .GMAP files were to store topographic maps, road maps, and nautical charts in a format that Garmin devices could efficiently process.
As the technology evolved and the demand for more sophisticated navigation solutions increased, the .GMAP file format also saw enhancements, accommodating a wider array of map types and data.
Origin Of This File.
.GMAP file format is a proprietary file format developed by Garmin Ltd., a multinational technology company known for its specialization in GPS technology for automotive, aviation, marine, outdoor, and sports activities.
The development of the .GMAP file format was driven by the need for a standardized way to store map data in a format that is easily accessible and readable by Garmin devices and software.
File Structure Technical Specification.
.GMAP file is essentially a container that holds various pieces of map data. This data includes but is not limited to topographical information, points of interest, road networks, and routing information.
The file structure is designed to optimize the reading and writing speed, ensuring that devices or software can quickly access the necessary map information.
Technically, .GMAP files are compiled and then locked to prevent unauthorized editing. This compilation process ensures the integrity of the map data and the reliability of the information provided to the end-users.
The file itself is structured in a way that allows Garmin devices and software to parse the information efficiently, ensuring fast load times and smooth performance.
How to Convert the File?
Converting .GMAP files to other formats is a process that enables the use of Garmin map data in various applications and devices.
Here’s a step-by-step guide to converting .GMAP files:
- Select Conversion Software:
- Choose software that can handle .GMAP files and convert them to the desired format. Common choices include Garmin MapManager (for Mac) and Garmin BaseCamp (for both Windows and Mac).
- Install the Software:
- Download and install the chosen software from the official Garmin website or other trusted sources.
- Open the .GMAP File:
- Launch the software and open the .GMAP file. In Garmin MapManager, this can be done by clicking on “File” and then “Import Maps”. In BaseCamp, you can add the map through the “Maps” menu.
- Convert the File:
- Once the .GMAP file is loaded, look for an option to export or convert the map. The conversion options depend on the software used.
- Common conversion formats include .KMZ or .KML (for Google Earth), .GPX (GPS Exchange Format), and others.
- Save the Converted File:
- After selecting the desired format, save the new file to your computer. Ensure you name it appropriately and choose a location where it can be easily found.
Advantages And Disadvantages.
Advantages:
- Reliability: .GMAP files are known for their accuracy and detail, making them a trusted source for navigation.
- Performance: The file structure is optimized for quick reading and writing, ensuring smooth performance on devices.
- Compatibility: Specifically designed for Garmin devices, offering seamless integration and functionality.
Disadvantages:
- Proprietary Format: Being a proprietary format, .GMAP files are not as versatile as some open-source alternatives.
- Limited Editing: Once compiled and locked, editing .GMAP files are not straightforward and usually require specialized software.
How to Open GMAP?
Open In Windows
Using Garmin BaseCamp:
- Download and install Garmin BaseCamp from Garmin’s official website.
- Open BaseCamp and the software should automatically recognize and list any .GMAP files if they are in the default location.
- If the .GMAP file is not in the default location, use the “Import” feature in BaseCamp to navigate to and open the file.
Open In Linux
Garmin does not provide native Linux support for .GMAP files. There are workarounds:
- Using Wine:
- Install Wine, a free and open-source compatibility layer that allows Windows applications to run on Linux.
- Download the Windows version of Garmin BaseCamp.
- Install BaseCamp using Wine, then open it and load the .GMAP file as you would on a Windows system.
- Alternative GIS Software:
- Use open-source GIS software like QGIS, which may support Garmin map formats indirectly through plugins or additional tools.
Open In MAC
Using Garmin MapManager and BaseCamp:
- Install Garmin MapManager and Garmin BaseCamp from the official Garmin website.
- Open MapManager, then import the .GMAP file. MapManager will integrate it into BaseCamp.
- Open BaseCamp, and the imported .GMAP files will be available for viewing and editing.
