GIS: Querying Spatial Data with Natural Language
A new prototype enables natural language interfaces for spatial databases running entirely locally.
Hello! Today is Friday and here’s your end-of-week-catch-up on all things geospatial.
🛠️ Tools & Software
- New Python package smoothifies raster conversions: A new open-source Python package solves the universal GIS problem of jagged, pixelated polygons from raster-to-vector conversion. Using a robust pipeline with advanced smoothing algorithms, it cleans up geometries from ML predictions and classified imagery without losing critical accuracy.
- Smarter field survey workflows demonstrated: A new tutorial demonstrates dynamic multiple-selection fields for mobile data collection using popular open-source GIS tools. This workflow allows field crews to tag single points with multiple attributes and add new options directly from a mobile app, perfect for evolving situations like ecological monitoring.
- Forgotten math creates perfect Global Grid: A rediscovered 1980s mathematical proof about pentagons has been used to create a new global grid system with true equal-area cells. The breakthrough offers zero distortion and eliminates the compromises of traditional geographic grids, potentially revolutionising global spatial indexing.
🤖 AI & Machine Learning
- Diffusion model creates clean terrain maps: A new AI approach transforms Digital Surface Model-to-Digital Terrain Model generation into a diffusion-based denoising problem. The model progressively "removes" buildings and vegetation from surface models, revealing clean ground elevation through methods inspired by image generation.
- Natural Language querying for local spatial databases: A new prototype enables natural language interfaces for spatial databases running entirely locally. Using open-source AI and database technology, users can ask plain English questions and get mapped results in seconds—all without cloud dependencies.
- Agentic GIS Resources Compiled: A major geospatial platform has released a comprehensive resource list for understanding Agentic GIS, covering everything from foundational concepts to technical implementation and real-world success stories.

🌐 Platforms & Data
- Solar API expands across Latin America: A major mapping platform's Solar API is now available in seven new countries across Latin America, providing key data for solar panel planning and low-carbon solutions. The update includes new datalayers like true-ortho imagery and building masks, expanding renewable energy planning capabilities.
📚 Publications & Resources
- New book on geospatial disaster management published: A new Elsevier book brings together critical insights and methodologies for using geospatial technologies to enhance disaster preparedness and response in the era of climate change.
📝 Tutorials
- Google Earth Engine tutorials
- How to fix broken map projections in Leaflet or any other WebGIS library
💡 Tip or resource of the week
- Curated Hub for map inspiration released: A new curated list of information designers and cartographers provides an excellent resource for visual inspiration and community connection during mapping challenges and everyday projects.
