What is a .REF file?
The file extension ".REF" is associated with a type of file known as a Microsoft Train Simulator Reference File. However, it's important to note that this description might be a bit misleading. In reality, .REF files are primarily used by IDRISI Taiga, which is a software application focused on Geographic Information Systems (GIS) imaging. These files are not directly related to Microsoft Train Simulator.
A .REF file contains geographic reference information. This means it has data that helps map or project raster images (like satellite photos or maps) according to specific measurements of distance, area, or other units. This is crucial for accurately displaying geographic images in a way that matches the real world. For example, if you have a satellite image of a forest, a .REF file would help ensure that the image is correctly aligned and scaled on a map, based on real-world coordinates and measurements.
These .REF files are especially useful because they can be applied to multiple raster images (.RST files), making it easier to manage large sets of geographic data. Essentially, they help ensure that all your images line up correctly and are displayed accurately according to the Earth's geography.
To open a .REF file, you can use several programs, but two main ones are mentioned here: 1. **GDAL (Geospatial Data Abstraction Library)**: This is a translator library for raster and vector geospatial data formats. It's a very powerful tool used in the GIS community for reading and writing a wide range of data formats. GDAL can open .REF files and help manipulate the geographic information contained within them.
2. **Clark Labs TerrSet**: This is an integrated GIS and remote sensing software developed by Clark Labs. It's designed for monitoring and modeling the Earth system and is widely used in environmental research and management. TerrSet can also open .REF files, allowing users to work with the geographic reference information in the context of their broader GIS projects.
Additionally, it's mentioned that many preinstalled .REF files can be found in the `\GEOREF\` directory of the IDRISI Taiga installation. This means that when you install IDRISI Taiga on your computer, it comes with a number of these reference files already included. These can be a valuable resource for getting started with geographic projects, as they provide ready-to-use reference information for various locations.
Verification
Our goal is to help people find the most up-to-date information about file extensions for Windows, Mac, Linux, Android and iOS. We researched over 10,000 file extensions and their respective programs that open those files.
