Tutorial: loaders.gl-showcases#

This project is a 3D geospatial data viewer designed to display and interact with large 3D datasets like buildings and terrain. It allows users to load data from different sources, including ArcGIS, manage multiple layers, and visualize them using either Deck.gl or ArcGIS map engines. It also includes tools for debugging and validating the 3D data and a comparison mode to analyze datasets side-by-side. The application state, including camera view and loaded layers, can be saved and restored as bookmarks.
