FAQ
BIL to RLA Conversion
What are BIL files?
BIL is a binary raster format developed by ESRI to store multi-band remote sensing data, hyperspectral imagery, and continuous surface models such as Digital Elevation Models (DEMs). As an uncompressed layout where pixel data is organized sequentially by lines across all available spectral bands, a file of this type cannot be read independently because it completely lacks embedded geospatial or structural metadata. To function within a geographic information system, a .bil file must be accompanied by a plain-text sidecar file with a .hdr extension, which explicitly defines critical parameters including the total number of rows and columns, the band count, the data type, byte order, and optional georeferencing information. This raw format is traditionally complemented by other sibling files like .blw for spatial coordinates, .stx for statistics, and .prj for the map projection.
What are RLA files?
The RLA image format, whose name stands for Run-Length Encoded Version A, is associated with the animation package Wavefront Advanced Visualizer. RLAs are output files storing 3D data and used for exchanging graphical data with other applications. They store several types of information, including images captured from live video, 3D rendered images and graphic images, field-rendered images and multichannel rendered image data.
