Referencing core · Implementations of Coordinate Reference Systems (CRS), conversion and transformation services derived from ISO 19111.
EPSG database · Provides the SQL script files for creating a local EPSG database when first needed.
Metadata core · 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.
XML base · Basic utilities for XML marshalling and unmarshalling. Those utilities are built on top of the JAXB framework.
Metadata on SQL · Stores metadata in a SQL database. Each metadata class is mapped to a table, and each metadata attribute is mapped to a column in the appropriate table. Tables and columns are created only when first needed.
Geotoolkit.org · Geotoolkit.org (abridged Geotk) is a free software, Java language library for developing geospatial applications. The library can be used for desktop or server applications.
Referencing · Projects group for referencing services. This group contains the core of referencing services (geotk-referencing) and various plugins.
Metadata · Group of modules related to handling metadata. The "geotk-metadata" sub-module contains the core classes and an implementation of the ISO 19115 standard. The "geotk-metadata-sql" sub-module provides services for metadata storage in a SQL database. The "geotk-metadata-fra" sub-module is a profile of ISO 19115.
Log4J logging adapter · An adapter for using Log4J in Geotk. Geotk will automatically redirect all its logging events to Log4J if this JAR is on the classpath. If there is no need for Log4J inter-operability, we recommend to NOT include this JAR on the classpath in order to use the default Java logging framework instead.
Modules · The modules that are components of the Geotoolkit.org library.
Referencing 3D · Transforms coordinates from "heights above the ellipsoid" to "heights above the geoid". This module provides the algorithms from an Earth Gravitational Model as a MathTransform implementation. Installing the JAR on the classpath should be sufficient for making vertical transformations available to an application like any other transforms.
Nature · Miscellaneous algorithms related to natural quantities. Most of those algorithms are determined empirically.
Metadata France · French extensions to ISO metadata. Those extensions are standardized by AFNOR (Association Française de Normalisation). All extended classes begin with the FRA_ prefix.
Apache logging adapter · An adapter for using Apache's commons-logging in Geotk. Geotk will automatically redirect all its logging events to commons-logging if this JAR is on the classpath. If there is no need for commons-logging inter-operability, we recommend to NOT include this JAR on the classpath in order to use the default Java logging framework instead.
