[Incubator] Request to register SFCGAL as an OSGeo community project

[Loic Bartoletti]

Hi,
As requested by Jody, I've updated the page by adding a small banner [1] with some recent images and a photo of our latest code sprint.

 Hey I found your profile in the footer - and gave you "project author" status. When you have the page ready for review please let me know. And yes when that is ready one of the incubation committee members here can make the motion for SFCGAL to be a community project.- -Jody Garnett On Sep 25, 2024 at 12:26:24 AM, Loic Bartoletti via Incubator <incubator at lists.osgeo.org> wrote:Hello,

I am writing on behalf of the team behind the SFCGAL (Simple Features for Computational Geometry and Algorithms Library) project to apply for OSGeo Community Project status.

SFCGAL provides advanced 2D and 3D operations, computations, and analysis functions for geospatial data. It enhances the capabilities of GIS (Geographic Information Systems) by providing complex geometric computations, which are essential for 3D modeling and spatial analysis tasks. Our goal is to facilitate the use of advanced computational geometry algorithms within the geospatial community through a standardized and open platform.

Since its inception, SFCGAL has grown significantly, reaching several releases, with the latest version being 1.5.2 and a 2.0.0 will be released very soon. The project has been in continuous development thanks to the efforts of a dedicated team of contributors and is currently used in various applications requiring high-precision 2D and 3D spatial analysis. The integration with GIS tools like PostGIS and GDAL further demonstrates the utility and robustness of SFCGAL. Additionally, a QGIS plugin ([QSFCGAL](https://gitlab.com/oslandia/qgis/qsfcgal)) is currently in development to extend QGIS 3D and advanced 2D, thanks to [(Py)SFCGAL](https://sfcgal.gitlab.io/pysfcgal/).

Historically, SFCGAL was a project initiated by [IGN France](https://www.ign.fr/) (National Institute of Geographic and Forest Information) and [Oslandia](https://oslandia.com/). It has always been an open-source project, and it now has its own independent entity but mainly funded by Oslandia.

With the support of OSGeo, SFCGAL aims to expand its community, enhance its governance, and promote its features to a wider audience.
