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, someone in the Malagis GIS group was looking for historical maps of Chinese dynasties. While a friend from Qingdao shared some high-resolution scanned maps, I remembered seeing an online historical map service maintained by an institute in Taiwan. After asking GPT, I found it again. If you're interested in historical geography, this is a valuable resource.
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.
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.

Many readers have requested software resources for Global Mapper Pro. As I rarely use this software personally, updates were infrequent. Recently, my article "How to Download Online GIS Map Services for Local Use?" covered methods for downloading WMTS and other map services, with several users recommending Global Mapper Pro. Out of curiosity, I researched Global Mapper Pro resources and discovered three recent versions (v24, v25, v26). I'll share these incrementally in future posts.
I've frequently seen peers inquire about entering GIS development. Though still refining my own expertise, my journey from computer novice to professional developer offers insights worth sharing. This article outlines a goal-oriented approach that helped me navigate the field – perhaps it will resonate with you too.
