GeoParquet Visualizer

* Loading Data: Visualize .parquet or .geoparquet files by dragging them from your desktop or loading them from a remote URL. * Plain Parquet Support: Automatically detects lon/lat columns as point geometry if no WKB geometry column is found. * Dynamic Styling: Change the color and opacity of points, lines, and polygons for each layer on the fly. * Globe View: Toggle between the standard Mercator projection and a beautiful 3D globe view. * Geocoder Search: Easily navigate the map by searching for locations worldwide. * Layer Management: Reorder layers by dragging and dropping them in the sidebar to control which datasets appear on top. * Stateful URLs: The map's view, projection, loaded datasets, basemap style, and background color are stored in the URL, so you can share your exact session with others. * Inspect Features: Hover over any point, line, or polygon to see its properties in a popup. One of the most powerful features of the visualizer is its ability to be controlled entirely through URL parameters. This makes it easy to bookmark specific views, pre-load datasets, and share your customized map with others. Example for loading a remote geoparquet file, setting the view to a tilted globe with a black background, and closing the sidebar: https://do-me.github.io/geoparquet-visualizer/?map=9.77/45.73/7.39/30.00/60.00&sidebar=0&style=https://tiles.openfreemap.org/styles/liberty&background=%23000000&projection=globe&url=https://huggingface.co/datasets/do-me/Italian_Parcels/resolve/main/VALLE-AOSTA_communes.geoparquet GeoParquet Visualizer is the open-source project do-me/geoparquet-visualizer (https://github.com/do-me/geoparquet-visualizer) by do-me, released under MIT.
