OSRM (Open Source Routing Machine) is a high-performance routing engine written in modern C++, specifically designed for computing the shortest path in road networks. Its core objective is to provide a fast, reliable, and customizable routing solution capable of handling continental-scale road network data, returning results in milliseconds. It serves as an ideal underlying engine for building applications such as map navigation, logistics distribution, and location-based services.
In the previous article, QGIS 4.0 Roadmap Unveiled: Major Qt6 Migration Scheduled for October Release, we introduced some early news about QGIS 4.0. According to the official roadmap, QGIS 4.0 (based on Qt 6) was expected to be released in October 2025—around this time. However, upon checking the official website yesterday, it appears that QGIS 4.0 has been officially delayed, with the new release date now set for February 2026.

During a casual chat in the MalaGIS WeChat group, someone asked when GIS skills become most useful in daily life. Answers ranged from food delivery route optimization to travel planning, but the most insightful response was "assessing location (including Feng Shui) for property purchases". Among factors like sunlight access—a critical yet often overlooked parameter—most standard map apps fail to provide this data, requiring specialized GIS software (refer to methods in "ArcGIS 3D Handbook: Sunlight and 3D Path Analysis"). Recently, I discovered an online WebGIS application that simulates sunlight and shadows for any global location at any date—an excellent tool worth sharing.

ShadeMap enables browser-based simulation of mountain, building, and tree shadows at any global coordinate for customizable dates/times. Users achieve precise, interactive sunlight and shadow analysis without client installations.
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.
pyroSAR is an open-source Python framework designed for large-scale Synthetic Aperture Radar (SAR) satellite data processing. Its core objective is to provide a complete and scalable solution for SAR data organization, processing, and analysis, integrating data acquisition, metadata management, preprocessing, and interaction with mainstream processing software like ESA SNAP. This significantly simplifies complex SAR data processing workflows.

Previously, I shared resources for Downloading and Installing Global Mapper Pro v24.0, but that version is a bit outdated. Now, I'm updating to the Global Mapper Pro v25.1 resource that I'm currently using. This article will share the installation package that I have personally tested and verified to work. Additionally, the installation method for Global Mapper Pro v25.1 is slightly different from that of Global Mapper Pro v24.0, so this article will also introduce the detailed installation steps.
The latest leaked ArcGIS Pro 3.4 learning edition with Chinese localization is now available. I've personally verified its functionality—installation is straightforward. Users interested in exploring can upgrade using this version.
Following our previous articles on the https://malagis.com/gis-data-share-2010-2020-global-forest-age-distribution-gami-data.html and https://malagis.com/qgis-open-netcdf-file-methods-summary-solutions.html, we introduce Ncview - a specialized tool for quick visualization of netCDF format data without launching full GIS applications.
Following our previous article 《https://malagis.com/arcgis-pro-3-1-6-installation-problem-solution.html》, we're sharing a community-developed utility that addresses persistent application anomalies. This tool efficiently resets user configurations to resolve multiple operational failures.
