Hi Joana, *I agree with the timeslot. Here is an intro of my tutorial:*
Integrate Apache SIS with Apache Sedona – CRS Transformation, GeoTiff Reader and more Apache Sedona is a high-performance cluster computing system designed specifically for processing large-scale spatial data. The system leverages a number of open-source libraries, including GeoTools, to execute spatial operations such as Coordinate Reference System (CRS) transformation and file reading. However, as an Apache project, Sedona is striving to reduce its reliance on GeoTools due to licensing issues. In order to address this challenge, Sedona is migrating affected functions to Apache SIS, which offers improved support for CRS transformation. This tutorial aims to provide a comprehensive introduction to Apache Sedona, covering its background and architecture, as well as several coding examples. Additionally, we will offer tips and tricks for hacking Sedona, in order to optimize your experience working with the system. Technologies: Java, Scala, Apache Spark, Apache Flink, and Intelijj IDEA Requirements: A basic understanding of Coordinate Reference System is recommended. Stream leader: Jia Yu and Martin Desruisseaux *Here is an intro of the proposed project* Apache Sedona is a high-performance cluster computing system designed specifically for processing large-scale spatial data. The system leverages a number of open-source libraries, including GeoTools, to execute spatial operations such as Coordinate Reference System (CRS) transformation and file reading. However, as an Apache project, Sedona is striving to reduce its reliance on GeoTools due to licensing issues. In order to address this challenge, Sedona is migrating affected functions to Apache SIS, which offers improved support for CRS transformation. In this code sprint, we will concentrate on replacing GeoTools' usage in two key functions within Sedona: ST_Transform and the GeoTiff reader. Our focus will be on demonstrating how to migrate these functions to Apache SIS, providing a comprehensive tutorial on the necessary steps involved. By the end of this code sprint, you will have a solid understanding of how to replace GeoTools with Apache SIS within Sedona's functionality, allowing you to effectively tackle large-scale spatial data processing tasks.
