I am working on a shiny/ leaflet map project which requires display of a large polygon dataset (40,000 polygons ~92MB sf object). Needless to say it take quite a time to render the sf object and zoom in and out.
Simplifying the polygons is not an option. leaflet.mapboxgl https://github.com/rstudio/leaflet.mapboxgl package allows adding of Mapbox GL layers to a leaflet map. Since I am using my own local tiles there should be no need for a maxbox access token. If possible I would like to make use of leaflet.mapboxgl: addMapboxGL() to display vector tiles ( as .mbtiles) of the polygons that have been pre- rendered from the polygon dataset using tippecanoe https://github.com/mapbox/tippecanoe and served using mbtileserver https://github.com/consbio/mbtileserver all on the same local machine. mbtileserver is running from the project directory, and the mbtiles are in the path: <R project directory>/tilesets/mytiles.mbtiles I can vie the preview in the bowser a http://localhost:8000/services/myTiles/map however the polygons do not dispay in leaflet in r As this requires use of tippecanoe and mbtileserver I cannot post a repro, however below is a pared down version fo the code I am using : library(leaflet) library(leaflet.mapboxgl) options(mapbox.accessToken=NA) base_map <- leaflet() %>% setView(lng = 145,lat = -37,zoom = 7)%>% addProviderTiles("Esri.WorldTopoMap", group = "ESRI Topo") %>% addMapox http://localhost:8000/services/myTiles ") have I simply got the wrong format/ incomplete URL fo the addMapboxGL ? If so what should it be? thanks [[alternative HTML version deleted]] _______________________________________________ R-sig-Geo mailing list R-sig-Geo@r-project.org https://stat.ethz.ch/mailman/listinfo/r-sig-geo
