FAQ
REL to U3D Conversion
What are REL files?
REL is the metadata file of the MiraMon raster format. MiraMon is a geographic information system and remote sensing program developed in Catalonia at CREAF, a research center linked to the Autonomous University of Barcelona. A MiraMon raster is stored in two kinds of files: the image data in one or several .img files, and a text file whose name ends in I.rel, which describes how to read them. It tells how many rows and columns the image has, what the pixel values are, how the bands are named, how the picture is compressed, where it lies on the Earth, and how it should be colored by default. It can also hold information about the origin and quality of the data. A single .rel file can tie together a whole multiband image, such as a satellite scene.
What are U3D files?
U3D (Universal 3D) is a standardized file format used to store and exchange 3D models and scenes. It supports geometry, textures, colors, lighting, and animations, allowing complex 3D content to be represented efficiently. U3D is best known for its use in interactive PDF documents, where users can rotate, zoom, and explore embedded 3D models. The format is widely used in engineering, architecture, manufacturing, medical imaging, and scientific visualization.
