Spatial DECM is a lightweight browser-based map viewer for spatial data. Users can upload supported files directly in the webpage, visualize them on top of a dark CartoDB basemap, edit uploaded layers, draw new features, and manage multiple layers independently.
Extremely fast client-side watershed delineation at over 60fps for high-res delineations (over 1,000,000 gridcells) with stream snapping. No backend/server. Works on mobile.
