    • Apache SIS utilities Miscellaneous utilities.
    • Apache SIS profiles Group of modules for extensions specific to some organizations or countries.
    • Apache SIS referencing Implementations of Coordinate Reference Systems (CRS), conversion and transformation services derived from ISO 19111.
    • Apache SIS common storage Provides the interfaces and base classes to be implemented by various storage formats.
    • Apache SIS build helper Define Maven Mojos and Javadoc taglets for generating resource files or formatting the Javadoc. While any project could use it, this module is primarily for internal use by Apache SIS and may change in any future version.

    • Apache SIS NetCDF storage Bridge between NetCDF Climate and Forecast (CF) convention and ISO 19115 metadata.
    • Apache SIS Apache SIS is a free software, Java language library for developing geospatial applications. SIS provides data structures for geographic data and associated metadata along with methods to manipulate those data structures. The SIS metadata module forms the base of the library and enables the creation of metadata objects which comply with the ISO 19115 metadata model and which can be read from or written to ISO 19139 compliant XML documents. The SIS referencing module will enable the construction of geodetic data structures for geospatial referencing based on the ISO 19111 model such as axis, projection and coordinate reference system definitions, along with the associated operations which enable the mathematical conversion of coordinates between different systems of reference. The SIS storage modules will provide a common approach to the reading and writing of grid coverages applicable to simple imagery as to many dimensional data structures.
    • Apache SIS French profiles Extensions to ISO-19115 metadata mandated by the French government.
    • Apache SIS core modules Group of modules providing the core of Apache SIS services: metadata, referencing, geometry, feature, coverage, rendering.
    • Apache SIS storage Group of modules for reading and writing data from/to various storages. Storages are typically file formats or a database schemas.
    • Apache SIS metadata Implementations of metadata derived from ISO 19115. This module provides both an implementation of the metadata interfaces defined in GeoAPI, and a framework for handling those metadata through Java reflection.
