CMR File – What is .cmr file and how to open it?

Overview of CMR Files

A CMR file is a digital representation of a sectional aeronautical chart, specifically used for aviation navigation. Developed by Naviter, a leading provider of electronic flight bag (EFB) solutions, CMR files offer a comprehensive view of airspace, terrain, obstacles, and other critical information within a specific geographic region. These files are designed to be used in conjunction with compatible EFB software, allowing pilots to access charts and data during flight, enhancing situational awareness and improving safety.

Benefits and Features of CMR Files

CMR files provide several advantages over traditional paper charts. They are highly detailed, ensuring pilots have access to the most up-to-date information. The digital format allows for easy zooming, panning, and searching, facilitating efficient navigation. Additionally, CMR files can be integrated with other navigation data sources, such as GPS and weather information, providing pilots with a comprehensive picture of their flight situation. By eliminating the need for bulky paper charts, CMR files reduce cockpit clutter and increase overall cockpit efficiency.

Opening CMR Files with Naviter Software

CMR files, or U.S. Sectional Chart Map Files, contain geospatial data used in aviation navigation. To open and utilize CMR files, you will need access to Naviter software, specifically the Naviter Mobile App for Android or iOS devices. The Naviter Mobile App is a mobile-friendly version of Naviter’s proprietary navigation software, which provides users with access to detailed navigational maps, charts, and aviation data.

Once you have installed the Naviter Mobile App, you can open CMR files by importing them into the application. To do this, connect your device to your computer and navigate to the CMR file you wish to open. Select the file and choose the “Import” option within the Naviter Mobile App. The app will process the CMR file and load the map data into its interface. After importing the CMR file, you can access the map details, zoom in and out, pan across the map, and utilize other navigation tools provided by the Naviter Mobile App.

Alternative Methods for Opening CMR Files

Alternatively, if you do not wish to use the Naviter Mobile App, you can also open CMR files with other software solutions. One option is to use an online CMR viewer, such as the free CMR Viewer from AirSpace Explorer. This viewer allows you to load and view CMR files within your web browser.

Another option is to convert the CMR file to a more accessible format using a file conversion tool or software. One such tool is the free CMR Converter from BendixKing. This converter allows you to convert CMR files to various image formats, such as JPEG or PNG, which can then be opened with any standard image viewer.

CMR File Format

The CMR file format is a proprietary format used by the Naviter software suite for storing U.S. Sectional Chart Map data. Sectional charts are a type of aeronautical chart that depicts the terrain, airspace, and other relevant information for a specific region of the United States. CMR files are typically used by pilots and other aviation professionals for navigation and situational awareness.

CMR files contain a variety of data, including:

• Geographic data, such as terrain elevations, water bodies, and vegetation
• Aeronautical data, such as airports, airspace boundaries, and navigation aids
• Infrastructure data, such as roads, railways, and power lines
• Demographic data, such as population centers and land use information

CMR files are compressed using a proprietary algorithm, which makes them smaller in size than uncompressed files while still maintaining their high level of detail. CMR files are typically stored on SD cards or other removable media and can be loaded into a Naviter software application for viewing and navigation.

Using CMR Files

CMR files are primarily used by pilots and other aviation professionals for navigation and situational awareness. They can be loaded into a Naviter software application, such as Naviter Navigator or Naviter Flight Planner, which allows users to view the chart data on a map and plan flight routes. CMR files can also be used to create custom maps and charts for specific purposes, such as flight training or search and rescue operations.

In addition to aviation, CMR files can also be used for other purposes, such as land use planning, environmental modeling, and disaster response. The detailed geographic data contained in CMR files can be valuable for a variety of applications that require accurate and up-to-date information about the terrain and other features of a specific area.
