Layer \ncreation is done in 'JavaScript' using [`geoarrow/deck.gl-geoarrow`](https://github.com/geoarrow/deck.gl-geoarrow)\n(see [Features](https://github.com/geoarrow/deck.gl-geoarrow#features) section\nfor details on how and why layer creation is efficient).\n\n## Features\n\nCurrently, `(MULTI)POINT`, `(MULTI)LINESTRING` and `(MULTI)POLYGON` features are \nsupported by the following layer functions:\n\n* [`addGeoarrowScatterplotLayer`](https://r-spatial.github.io/deckglgeoarrow/reference/addGeoArrowScatterplotLayer.html) for point data\n* [`addGeoarrowPathLayer`](https://r-spatial.github.io/deckglgeoarrow/reference/addGeoArrowPathLayer.html) for linestring data\n* [`addGeoarrowPolygonLayer`](https://r-spatial.github.io/deckglgeoarrow/reference/addGeoArrowPolygonLayer.html) for polygon data\n\nSupport for other layers, such as `discrete global grid` layers (`S2`, `A5`, `H3`),\n`origin-destination` layers (`Arc`, `trips`) and `point-cloud` layers, \namong others, will follow.\n\n## Supported data sources\n\n#### R\n\nSpatial classes from the following R packages are supported (via `data` argument):\n\n* [`wk`](https://paleolimbot.r-universe.dev/wk)\n* [`sf`](https://r-spatial.r-universe.dev/sf)\n* [`geos`](https://paleolimbot.github.io/geos/)\n* [`terra`](https://rspatial.r-universe.dev/terra)\n\n#### Others\n\nThe following local or remotely hosted files types are supported (via `file`/`url` argument):\n\n* [`GeoArrow`](https://geoarrow.org/)\n* [`GeoParquet`](https://geoparquet.org/)\n\nNote, that due to a [restriction](https://github.com/geoarrow/deck.gl-geoarrow/issues/170) in the upstream JavaScript dependency, only files\nwith native `GeoArrow` geometry encoding are supported. `WKB` encoded geometries\nwill not render!\n\nIn addition, [`nanoarrow`](https://apache.r-universe.dev/nanoarrow) `array_streams` (as files) are supported.\n\n## Installation\n\nThe development version of deckglgeoarrow can be installed from [GitHub](https://github.com/r-spatial/deckglgeoarrow) with:\n\n```r\n# install.packages(\"pak\")\npak::pak(\"r-spatial/deckglgeoarrow\")\n```\n\n## Example\n\nTo showcase what the package can do, consider [this](https://raw.githubusercontent.com/r-spatial/deckglgeoarrow/refs/heads/main/inst/experiments/mapgl.R) example.\n\nHere, we visualise \n\n* 1M random points with random sizes and colors +\n* ~11k polygons colored by river basin + \n* ~155k lines colored and sized according to their [Strahler number](https://en.wikipedia.org/wiki/Strahler_number)\n\nin one map.\n\nHere's how quickly this renders:\n\n![](man/figures/deckglgeoarrow_demo.gif)\n\nMore examples can be found [here](https://github.com/r-spatial/deckglgeoarrow/tree/main/inst/experiments)\n\n### Acknowledgment\n\nThis project has been realized with financial [support](https://r-consortium.org/all-projects/2025-group-2.html#modernizing-rs-web-mapping-capabilities) from the\n\n\u003ca href=\"https://r-consortium.org/all-projects/2025-group-2.html#modernizing-rs-web-mapping-capabilities\"\u003e\n\u003cimg src=\"https://r-consortium.org/images/RConsortium_Horizontal_Pantone.webp\" width=\"400\"\u003e\n\u003c/a\u003e\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fr-spatial%2Fdeckglgeoarrow","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fr-spatial%2Fdeckglgeoarrow","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fr-spatial%2Fdeckglgeoarrow/lists"}
