In a previous article "Maptalks: An Open-Source Alternative to Cesium for Geospatial Visualization", we introduced maptalks as an alternative framework to Cesium. Recently, we discovered another open-source 2D/3D engine: three-tile. Designed for lightweight implementation with ongoing functional improvements, it already meets significant development demands. Here is a brief introduction.
While updating to QGIS 3.40.3, I stumbled upon a surprising fact: QGIS is now 23 years old – possibly older than many of its users. It’s remarkable that this powerful open-source GIS software, used worldwide for mapping, data processing, and service publishing, was born in the dial-up internet era. Since Gary Sherman wrote its first line of code in Germany in 2002, QGIS has quietly revolutionized spatial technology for 23 years. Debuting five years before the iPhone and thirteen years before TensorFlow, this open-source GIS has not only survived three technological earthquakes (the dot-com crash, mobile revolution, and AI explosion) but evolved from a basic map viewer into global geospatial infrastructure. Let’s journey through time to uncover how this "living tech fossil" defied commercial giants to become king.
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.
During discussions in our GIS community chat, a colleague humorously noted: "After three years in 3D GIS, my most frequent projects are dashboards." This resonated widely among GIS developers, highlighting a common industry reality—dashboard projects dominate the WebGIS landscape. While not technically complex, these projects demand meticulous attention to aesthetic details like color schemes that consume disproportionate time.
Introducing BigDataView: An open-source repository of dashboard templates designed to alleviate this pain point.
TorchGeo is a PyTorch domain library, similar to torchvision, specifically designed for geospatial data. It provides datasets, samplers, transforms, and pretrained models to help machine learning practitioners work with geospatial data and enable remote sensing experts to explore machine learning solutions.
