Apache SIS is a Java language library for developing geospatial applications. The library is an implementation of OGC GeoAPI 3.0.2 interfaces and can be used for desktop or server applications. SIS provides data structures along with methods derived from the following international standards:
- Metadata — ISO 19115-1, ISO 19115-2, ISO 19115-3, ISO 19157
- Referencing — ISO 19111, ISO 19111-2, ISO 19112, OGC 01-009
- Features and filters — ISO 19109, ISO 19143
- Units of measurement — ISO 19103, JSR 385
- Data formats:
- GeoHEIF
- GeoTIFF — OGC 19-008
- NetCDF — OGC 10-092, OGC 16-114
- XML and GML — ISO 19139, ISO 19136, OGC 01-009
- WKT (Well-Known Text) — ISO 19162
- CSV (Comma-separated values) — OGC 14-084

Running the library part of Apache SIS requires Java 11 or higher. Running the JavaFX application part requires Java 22 or higher. Building SIS requires Java 22 or higher together with Gradle 8 build system. To build SIS, use the following command in this directory:
gradle assemble
The JAR files will be located in the following directories, together with their dependencies:
endorsed/build/libs/(core library)optional/build/libs/(requires JavaFX)incubator/build/libs/(not yet released)
If JAR files seem missing, try gradle jar.
For publishing to the local ~/.m2 repository
(for example, for use with Maven projects):
gradle publishToMavenLocal
If the optional modules prerequisites are met,
a ZIP file containing a subset of Apache SIS modules and dependencies
is automatically built in the optional/build/bundle/ sub-directory.
That ZIP file can be unzipped in any directory and the application is
launched by running the ./bin/sisfx script.
Information for running a command-line tool or an optional JavaFX application can be found on the web site. Java code examples for some common tasks are given in the How to… pages. Complete API can be browsed in online Javadoc.
