When visualizing national highway mileage across Chinese provinces in QGIS, I needed provincial capital markers without local data access. Using DeepSeek AI, I generated geographic layers directly in QGIS via Python scripting.
Visualization requiring provincial capitals
Following our guide on https://malagis.com/qucik-build-a-cesium-study-example.html, this article addresses limitations of Cesium Ion—particularly accessibility challenges for Chinese users—by demonstrating alternative basemap integration methods.
The ImageryLayers class manages map imagery display in CesiumJS, enabling:
This article contrasts the core technical specifications of Landsat 9 and Sentinel-2, key Earth observation satellites for environmental monitoring.

For global-scale visualizations (e.g., GDP distribution maps), complex tile services like WMTS/WMS are often unnecessary. ECharts-GL provides six high-quality static basemaps—including Earth and lunar datasets—that offer lightweight alternatives to conventional tile services. These pre-rendered images work seamlessly with Cesium, Leaflet, and other mapping frameworks.

When integrating Cesium into a legacy UMI3-based WebGIS project, Node version compatibility issues arose due to Cesium's requirement for Node ≥18.18.0. Direct Node upgrade would trigger extensive regression testing, making alternative deployment approaches necessary.
When deploying CesiumJS projects, the library's substantial size (~100MB) often slows CI builds. This analysis evaluates domestic CDN options for external Cesium loading to optimize deployment efficiency without compromising functionality.
Following Bentley Systems' acquisition of Cesium and its increasing commercial integration, GIS professionals are exploring alternative open-source solutions for 3D geospatial projects. Maptalks emerges as a viable option, particularly for projects requiring domestic innovation ecosystem compliance.
As an alternative to the MapPlus solution presented in our previous article 《Creating Dynamic Marathon Route Visualizations with MapPlus: A No-Code GIS Solution》, this guide demonstrates a Cesium-based implementation for dynamic route visualization. Developed with ChatGPT assistance and requiring no commercial subscriptions, this approach achieves approximately 70% of MapPlus functionality.
When working on data processing projects with ArcGIS Desktop (non-Pro version), extending arcpy functionality often requires installing third-party libraries. Since Python 2 doesn't include pip by default, this guide outlines the installation process.
