Idrisi
raster
Idrisi Kilimanjaro is a versatile raster GIS system developed by Clark Labs at Clark University. The native raster format supports one raster with one or three bands. A header file is required to open the file.
| General |
Simple file-based format for a single raster with one or three bands having a single data type. Single band rasters are either dspFloat32, dspInt16, or dspUInt8. The three band file is always dspUInt8 for all three bands. Because this is a flat file format, it is one of the fastest formats available in DSpatial for dspUInt8, dspInt16, or dspFloat32 rasters having only a single band. |

| Read |
The driver reads uncompressed binary data in REAL, INTEGER, RGB8, and RGB24 formats. Compressed files and ASCII files are not supported. A header file with the same name as the data file but with a .RDC extension is required. |
||||||||||||||||||||||||
| Write |
The driver can write a new file, or modify an existing file. A header file is automatically created, if required. |

| Attributes | The header file can contain attributes, but these are currently not supported. | ||||||||||||||||||||||||
| Coordinate system |
Coordinate system information is contained in the header file, but this is currently not supported. |

| Documentation | The complete documentation for Idrisi Kilimanjaro is available from Clark Labs. | ||||||||||||||||||||||||
| Data sources | Idrisi files are not commonly distributed over the internet, but Clark Labs sells CDs with global data in Idrisi raster format. | ||||||||||||||||||||||||
| Developer information |
The data files are in a flat binary layout, or interleaved by pixel (RGB24). DSpatial will read the following keywords from the accompanying header file (in no particular order):
None of the keywords have a default value. More keywords are defined for the header file. Please check the online documentation for more details. |
