BIL (or Band Interleaved by Line) is a raster .bil file format developed and used primarily by ESRI. The files are commonly saved with an accompanying header file ending in the same base name, but with a .hdr extension. BIL files are used to store multi-band surface reflectance data for satellite imagery and aerial photography. In general, this data format contains two files: one for the raster data itself and one header file that contains information about the dataset, including the type of the data (e.g. byte, integer).
File Structure
BIL files have a binary format and they are composed of raw raster data with an associated header file. The file structure consists of regularly spaced array of lines or columns containing samples arranged in parallel bands. There may be 1 or multiple parallel bands per BIL file, depending on the data contained. Each band contains the same number of lines and the same number of columns as the other bands.
Similar File Types
BIL is just one type of raster file out of many, including the related but distinct ERDAS Imagine .img, NITF .ntf, GeoTIFF .tif, HDF .hdf, Digital Raster Graphic .drg, MS Windows BMP .bmp, JPEG/JFIF jpg or.jpeg, Portable Networks Graphics .png, GIF Graphics Interchange Format .gif, Sun Raster/Sun TAAC .ras formats.
Programs for WINDOWS system
After installing the required software, the operating system will usually automatically associate an unknown file type (in this case .BIL) with the new application. If this does not happen, we can help the system a bit by selecting the software for it, which it should always use to open files with the .BIL extension.
When choosing the software we can select the system to use this software every time.
Remember!
Using it for the first time it is good to check whether the .BIL file opened in the application can be read by us and opens in a way that allows us to use it. If everything is in order, select this option the next time you open a file with the .BIL extension. However, if the file has not opened correctly, we have to look for a different software, with which we can open files with the .BIL extension. Select a different software from our list and install it on your computer. After the software is installed, repeat inspection openings of a .BIL file. Sometimes you have to repeat the operation several times.
Other instructions
If none of the programs listed by us to work with the .BIL file has not meet your expectations, you can try searching other websites. But remember to avoid downloading programs "that can open any file". These applications not only have very limited functionality, but may also expose you to expense tens of dollars when purchasing a license.
In the vast majority of cases you will find the program dedicated to support the .BIL file, or any other file format. In addition, there is a chance that it will be a free program, and its functionality (concerning the .BIL file) will be extended to the maximum.
It is also good to check
- if the .BIL file has no errors
- or if it has been copied (or downloaded by the browser) thoroughly
