I’ll share some of good technical articles and blogs which I came across. Awesome Vector-tiles . List of parsers and generators, clients and geospatial tools. What are Vector-tiles? . Good summary of vector-tiles and why should we care Awesome MapBox Resources - List of external resources if you are using Mapbox Tiling - Good reading on tiling. Must for any geospatial Engineer Src vs Flat Layout - Gives good undertsnading of python packaging and layout structure....

This post walks you through the process of creating an API with geospatial capabilities using FastAPI and Pixi. Many data science and machine learning projects today use Conda for environment management and Poetry for package management. Using Poetry and Conda together in Python projects creates challenges due to their conflicting approaches to environment management and dependency resolution, often leading to inconsistencies in package versions and sources. The combination increases complexity in CI/CD pipelines and Dockerfiles, making it difficult to maintain consistent environments across different stages of development and deployment....

Recently came across the geospatial tech radar article published by Element84. This was widely recieved with in gis community and many conversations/discussions happened in social media (twitter/linked-in). The radar aims to highlight technologies that are proven and mature (Adopt), technologies that are ready for use but not fully proven (Trial), technologies worth looking at closely but not necessarily for trial (Assess),and technologies that haven’t happened yet but have forthcoming developments (Watch)....
