What is a .LEN file?
A .LEN file is a type of effects file specifically used by a software called ERDAS IMAGINE. This software is primarily designed for professionals like archaeologists, engineers, biologists, geologists, and others who work with geographical and spatial data. The .LEN file contains special visual effects known as lens flare effects, which can be used to enhance both 2D and 3D images within the software.
Lens flare effects mimic the way light scatters when it hits a camera lens directly from a bright light source like the sun or a lamp. This can add a touch of realism to the images, making them more visually appealing or highlighting certain aspects of the scene.
To use these effects in ERDAS IMAGINE, you would typically go to the menu, select the option for adding a lens flare layer, and then choose the .LEN file where your desired effects are stored. This adds the effects to your current working scene in the software.
ERDAS IMAGINE itself is a comprehensive tool that offers a wide range of features beyond just adding lens flares. It's used for creating detailed 2D and 3D images, producing high-quality maps, and even making 3D movies. The software includes capabilities for spatial modeling, creating mosaics from multiple images, processing multiple tasks at once with batch processing, and detecting changes in geographical data over time.
In summary, if you are working with .LEN files, you are likely using them to add special lighting effects to images in ERDAS IMAGINE to enhance the visual quality of your geospatial projects.
