Extracting river/canal centerlines is a common task in GIS data processing. Users of ArcMap or ArcGIS Pro likely find it straightforward. Recently, many colleagues have started exploring QGIS, someone in My GIS Group asked about this, making it a good time to document the process.

PS: The author will focus on introducing methods to achieve ArcGIS-equivalent functions in QGIS. If you have specific needs in this area, feel free to leave a comment.

Following my previous article "This Certification is Highly Valuable for GIS Job Seekers, Yet Overlooked by Many", which helped numerous GIS professionals advance their careers, a middle school geography teacher recently requested vector data for China's geographic regional partitions for classroom presentations. After research, I'm sharing this valuable dataset.

A reader recently noted that my earlier guide on purchasing licensed ArcGIS Pro is outdated. Upon review, I confirmed this—Esri no longer offers ArcGIS Desktop 10.8.2 for personal purchase, leaving only ArcGIS Pro available. Essentially, individual users can no longer legally acquire Desktop versions.

Share the official ArcGIS 10.8.2 installation package (ISO format) containing all Desktop components, including the Simplified Chinese language pack. Additionally, a "Learning Edition" package is provided with all components, Chinese language support, and supplementary tools for unrestricted use.

Since launching ArcGIS Pro, ESRI has shifted focus away from ArcGIS Desktop. ArcGIS 10.8.2 represents the final major release of the ArcMap series. Despite this, it remains a robust solution for users transitioning from ArcGIS Pro.
