High-capacity image storage with mosaic datasets
Mosaics datasets allow you to store, manage, use, and share small-to-vast collections of imagery and raster data. A mosaic dataset is a flexible and scalable way to assemble and use a collection of original imagery source files ranging in size from quite small collections to massive amalgamations. For example, a mosaic dataset might represent a small collection of a few dozen orthophotos from a personal drone mission you just flew yesterday. Or at the other extreme, it might include a complete, continuous image collection of the world—such as the entire Landsat 8 collection stored and made available in Amazon Web Services or the Copernicus Sentinel-2 imagery of the world. Hundreds of new scenes are being added to both of these collections daily. Mosaics enable flexible storage, management, and use of these scenes as cohesive image collections.
Mosaic datasets in ArcGIS are versatile and elastic and can be updated at any time. They have the capacity to process and manage millions of imagery files as a single integrated dataset while ingesting ongoing updates and additions as satellites continually collect additional scenes. Mosaic datasets are always available and ready—an at-your-service data source. This is important given the growing data volumes coming from the ever-expanding series of earth observation platforms. Imagery from all satellite systems can be managed and served using mosaic datasets.
