| Apache <abbr title="Spatial Information System">SIS</abbr> is a free software, |
| Java language library for developing geospatial desktop or server applications. |
| This library provides services for data discovery (metadata), reading and writing vector or raster data, |
| filtering the data and applying operations such as map projections. |
| Apache <abbr>SIS</abbr> data structures follow closely the geospatial models defined in the international standards published by |
| the Open Geospatial Consortium (<abbr>OGC</abbr>) and the International Organization for Standardization (<abbr>ISO</abbr>). |
| The <a href="#Annexes">annex</a> provides more context about international standards. |
| </p><p> |
| The library is an implementation of <abbr title="Open Geospatial Consortium">OGC</abbr> <a href="http://www.geoapi.org">GeoAPI</a> interfaces. |
| In a series of <code>org.opengis.*</code> packages, GeoAPI offers a set of implementation-neutral Java interfaces for geospatial applications. |
| These interfaces closely follow the specifications of the <abbr>OGC</abbr>, while interpreting and adapting them |
| to meet the needs of Java developers — for example, conforming with Java naming conventions. |
| The conceptual model of GeoAPI will be explained in detail in the chapters describing Apache <abbr>SIS</abbr> implementation. |
| However, we can get an overview of its content by consulting the page listing the mapping between |
| <a href="http://www.geoapi.org/3.0/javadoc/content.html">GeoAPI methods and the standards where they come from</a>. |
| The <a href="#GeoAPI">annex</a> provides more details about GeoAPI history and how to use it. |
| </p><p> |
| While Apache <abbr>SIS</abbr> is primarily a library for helping developers to create their own applications, |
| <abbr>SIS</abbr> provides also an optional JavaFX application for testing its capability to read, transform and visualize data files. |
| Screenshots of this application may be used in this document for illustrative purposes. |
