GX Viewer

GX Viewer is a lightweight, web-based tool designed to render GX geospatial data streams for quick inspection. It supports both vector and raster layers, and can operate on local GX files or remote data sources. The goal is fast, accurate visualization without the overhead of a full GIS stack, making it suitable for data engineers, GIS analysts, researchers, and developers prototyping GX integrations.
Core processing centers on ingesting the GX payload, validating headers, and building a layered scene. It projects coordinates to a common reference (Web Mercator and WGS84 variants) and subdivides the viewport into tiles to enable smooth panning and zooming. The rendering path prioritizes correctness of geometry, feature visibility, and consistent styling across sessions.
Unique value proposition includes streaming-friendly updates, deterministic rendering across environments, and a minimal API suitable for automation. Common workflows include rapid QA of new GX feeds, exploratory data analysis, and lightweight visualization in data science pipelines where a full GIS client would be excessive.
Advanced users can tweak layer visibility, apply simple filters, and export the current viewport as an image or a small set of tiles for offline use. The tool is designed to be platform-agnostic, operating in modern browsers with no server-side dependencies and focusing on speed and reliability for GIS analysts, data engineers, and product teams.
