Just a tiny example with a ~1 GB .gpkg file (with an index)...the equivalent GeoParquet is ~600 MB (without an index), can be read into #rstats sf in a ~ 5 s, and can be written in ~3 s (mostly because of the 'arrow' package's use of ALTREP for strings) #rspatial

Right geo nerds! Does anyone have opnions on the best COG GeoTIFF spec for a single band raster when using georaster-layer-for-leaflet / leafem::leafem::addGeotiff?Happy to sacrifice accuracy/precision for performance! #rspatial #gischat #gdal🙏

#rspatial #gischat using QGIS instead of other interactive map packages in R: an example. I use postgis in the background (st_write in the end of the pipe), didn't manage to notify the database so I use a 0.1 interval refresh rate. For me it is a game changer.

7/n I ran the same survey for R. Guess what! 90% love RStudio. So it’s simpler to pick R. Everyone uses RStudio. We all learn the same way. But that’s just the 2nd reason.

Recently I compared the performance of the most popular packages for vector data processing in #python and #rstats. It seems that {terra} is mainly used for raster data, but it does quite well with vectors too. #rspatial #gischat

🤔How do others use ds in your industry? 🙋🏼‍♀️How do you start a meetup at your company? This site has been an idea for a while & makes me so happy to share. Lmk what you think. I'd love to keep adding resources (blogs, meetups, tips) from all♥️ rstudio.com/champion/ #rstats

I'm *soooo* close to wrapping up the development sprint I've been on for the last month. I've made several new mapping functions that I split off into a separate {birdseyeview} package (mainly to keep #overedge from getting too complex) elipousson.github.io/birdseyeview/r… #rspatial

#rspatial Do we need a package for using our own pictures as base maps? I don’t know, but anyway we have it! {rasterpic} 📦 is now on CRAN, and we can convert our pngs to spatial rasters like this cran.r-project.org/package=raster…

BAM! Thanks so much @TimSalabim3 for helping with this. I can't quite get over how well this works! >1million lines rendered in the browser (v fast) with no lag at all. Issue was some broken geometries and needing to add the src=TRUE arg in leafgl::addGlPolylines. #rspatial

Okay so a few people seemed interested in this so here is the issue on the {leafgl} github: github.com/r-spatial/leaf…. A regional subset of the river network renders nicely for all {leafgl}, {mapdeck} and {rdeck} but I was only able to render the full dataset with {rdeck}.

So the #rspatial workflow would be to tile first, load each tile separately and then process? I’m not sure about this because I am trying to classify the imagery with one set of samples for training and validation. Would I have to have individual samples for each tile? Thanks!
