Following our previous article 《「GIS Resource」Sharing WMTS Service for Chinese Historical Maps》, many users adopted the historical territory maps. However, those maps lacked contextual historical figures and events. Based on reader recommendations, we present a more comprehensive solution:
Following our previous article 《A WMTS Service for Historical Chinese Maps: How to Load in QGIS》, colleagues inquired about websites for querying global satellite parameters. Coincidentally, I recently discovered such a platform through video recommendations. The website remains operational and is shared here for relevant needs.
Recently, while testing OSGB data and related software, I explored using ArcGIS Pro for this purpose. After successful verification, this article documents the specific workflow.
In a previous article "Adding Centroid Coordinates in QGIS Using Field Calculator", we demonstrated adding centroid coordinates via QGIS. This article explains the mathematical principles behind centroid calculation for polygons.
When working with large SHP boundary files, exporting coordinates of specific district boundaries to TXT is straightforward in QGIS. Here are three approaches:
This article summarizes common Python GDAL code snippets for geospatial data processing. GDAL (Geospatial Data Abstraction Library) is a foundational library for handling raster and vector geospatial data, maintained by the Open Source Geospatial Foundation (OSGeo). Implemented in C/C++, it provides Python, Java, and other language bindings. When calling GDAL's API in Python, the underlying execution relies on compiled C/C++ binaries.

During a recent ArcGIS session, my team lead asked:
"Where are ESRI's servers located?"
"Probably in the US," I replied instinctively.
"That means signals from Wuhan travel quite a distance!"
This sparked my curiosity: Could we visualize this network path?
This tool enables rapid network path visualization. See sample output: 
During development of a grid management system, I initially planned to use PostgreSQL for storing grid WKT data (for direct SHP export and map service publishing). Due to incompatibility with backend framework requirements, I switched to MySQL. This necessitated converting MySQL-stored WKT to Shapefiles. The solution: Java scheduled tasks invoking Python scripts to automate conversion. Below are the code implementations.

Many GIS students inadvertently purchase MacBook only to discover that ArcGIS and most domestic GIS software lack macOS versions. This article summarizes solutions for running ArcGIS on M1 Macs. Better approaches are welcome in the comments.
