Could you build this?
Partial The viewer UI is straightforward, but compiling and coordinating GDAL via WebAssembly in the browser with full bidirectional conversion across 19+ geospatial projection formats requires specialized geospatial build tooling.
What it would actually take: The architecture uses MapLibre GL JS on the frontend with Emscripten-compiled GDAL/PROJ running in a Web Worker to parse and convert GIS vectors and rasters client-side. The primary bottleneck is compiling, optimizing, and stripping huge C/C++ geospatial libraries (GDAL, PROJ, GEOS) to WebAssembly within browser memory limits while maintaining correct coordinate reference system (CRS) projections. Specialized expertise in C++ WASM compilation and GIS data pipelines is required.
