SIS - Spatial Information System

Apache SIS is a spatial framework that enables better representation of coordinates for searching, data clustering, archiving, or any other relevant spatial needs.

Apache SIS is an effort undergoing incubation at the Apache Software Foundation, sponsored by the Apache Incubator PMC. Incubation is required of all newly accepted projects until a further review indicates that the infrastructure, communications, and decision making process have stabilized in a manner consistent with other successful ASF projects. While incubation status is not necessarily a reflection of the completeness or stability of the code, it does indicate that the project has yet to be fully endorsed by the ASF.

July 2012: New committers and PPMC members added
Several new PPMC members and committers have been added including Adam Estrada, Andrew Hart, Ross Laidlaw, Peter Karich and Charith Madusanka. Welcome, everyone! The Apache SIS site is undergoing several updates so watch for news here!
July 2012: Apache SIS release
The Apache SIS project made its second release, 0.2-incubating, and the download is now available! Please see the download page for more information. This is a minor, feature release and lots of exciting things are in the works for SIS!
November 2010: First Apache SIS release
The Apache SIS project made its first release, 0.1-incubating, and the download is now available! See the download page for more information.
September 2010: Nga Chung voted in as committer
The SIS project received a great Quad Tree contribution from Nga Chung as the final project in her CSCI 572: Search Engines and Information Retrieval class at USC, taught by Chris Mattmann. After the activity, the SIS PPMC and Incubator IPMC elected to add Nga as a committer to the SIS project. Welcome, Nga!
June 2010: Apache SIS status report
Mailing list activity has been pretty bare, but should pick up since the SIS'ers need to follow up after the meeting with ESRIlast month to determine if they are interested with participating in the community. Much of the other activity continues to be from the mentors and committers.
May 2010: Apache SIS status report
Chris Mattmann, Patrick O'Leary and Kevan Miller participated in a meeting with ESRI who may be interested in participating within the project within some capacity. This would be a huge win as ESRI is one of the major industry leaders in the development of GIS software, with connections to standards bodies including the Open Geospatial Consortium (OGC). Much of the other activity continues to be from the mentors and committers.

Chris Mattmann is working on refactoring the LocalLucene code into the SIS codebase and work continues on creating the SIS incubator website with Sean McCleese leading the charge. Patrick O'Leary is investigating map projections and coordinate systems including transformations to Polar coordinates which should help on the observational data side.

April 2010: Apache SIS status report
Chris Mattmann was contacted by an ESRI representative inquiring about the direction of the project. This lead will be followed as garnering support from ESRI would be big win for the project and attract a large community.

Chris Mattmann has finished importing the LocalLucene code into the SIS codebase and Patrick O'Leary has compiled around ~50,000 geocoded records for development/testing of SIS spatial functions. Work on creating the SIS incubator website has begun led by Sean McCleese as well.

March 2010: Apache SIS status report
We are working on the inclusion of point-radius, bounding box and polygon functionality into the first few releases.

There was a lot of positive interest from the Incubator community during the SIS proposal and voting process. We recently stood up our mailing lists and have begun to report JIRA issues, so we hope those are positive first steps to building an Apache-based community. Chris Mattmann discussed SIS over in the Lucene community as something to watch in terms of a common place for spatial code for Solr and Lucene to reside.

All mailing lists have been set up, all SVN accounts are up, and karma has been granted to all SIS committers. Sean McCleese and Patrick O'Leary volunteered to be list moderators, and Chris Mattmann is working on importing the Local Lucene code and standing up the SIS website. We will also begin work soon on porting the license headers for Local Lucene into SIS ASL 2.0 headers, and to port the package names for code (JIRA issues to be filed on this).

February 21st, 2010: Apache SIS project started
The Apache SIS project was formally started when the Spatial proposal was accepted by the Apache Incubator PMC.
