FAQ
DIM to FITS Conversion
What are DIM files?
DIM (Digital Image MAP) is a metadata-driven format for satellite imagery, developed by the French space agency CNES together with SPOT Image to describe products from the SPOT and Pléiades missions. A dataset consists of an XML file with the .dim extension and one or more image files stored beside it, usually as GeoTIFF or JPEG 2000 rasters, while earlier versions used BIL and TIFF files. The XML document describes the product identification, acquisition date and time, sensor and satellite parameters, geometric processing level, coordinate reference system, band names and order, radiometric calibration values, sun and viewing angles, and the image dimensions. Related files may hold preview images, quality masks, and rational polynomial coefficients for sensor model correction. The format is applied to panchromatic, multispectral, and pan-sharpened scenes at several processing levels, from primary to orthorectified products, and the .dim file acts as the entry point to the whole dataset.
What are FITS files?
The FITS (Flexible Image Transport System) format is a standard format used particularly for storing, transferring and processing scientific images from fields such as astronomy. FITS was first launched as an open standard in the early 1980s and has gone through several subsequent upgrades. FITS files contain not just images, but also data related to photometry and spatial calibration, and information about the origin of the image. Similar formats include FIT and FTS.
Can reaConverter convert DIM to FITS?
Yes! reaConverter instantly converts .dim to .fits with perfect quality preservation. With its batch processing feature, you can convert multiple files at once in just a few clicks. You can even convert images directly from Windows Explorer using the right-click menu — fast and convenient.
What is reaConverter used for?
reaConverter is a Windows converter for 800+ formats, GIS data among them. For DIM to FITS it replaces the usual detour through QGIS, ArcGIS or ogr2ogr: add the files, pick the output format, and the whole batch converts offline. Surveyors, planners and engineering teams use it to pass data between GIS, CAD and everyday document formats.
