The BIL (Band Interleaved by Line) data format is a raster data storage arrangement commonly used in remote sensing and geospatial applications. It organizes multi-band image data into a specific file format to facilitate efficient storage, processing, and analysis of satellite or aerial imagery.
In the BIL format, pixel values for each band are interleaved along the rows of the image. The data structure can be understood as follows:
Band Interleaving:
Single-Line Structure:
Efficient Data Access:

BIL is part of a family of data formats that includes other interleaving schemes like Band Interleaved by Pixel (BIP) and Band Sequential (BSQ). The choice between these formats depends on factors such as data processing requirements, software compatibility, and specific application needs. BIL is particularly useful when efficient band-wise access to pixel values is a critical consideration in remote sensing and image analysis workflows.
