On the blog: how to map hundreds of thousands of US Census blocks performantly with R and PMTiles.

This is the first in a three-post series on production mapping workflows for big spatial datasets with PMTiles.

Super easy to use the mapgl package and @oldinsurancemaps.net to compare 1886 Richmond, VA to today in #rstats. The site of Gallego Mills, the ruins of which became an iconic photo after the fall of Richmond in the American Civil War, is now an office building and freeway.

One thing I'm noticing with Claude Sonnet 4.5 compared with older models - it's much more willing to tell me I'm wrong.

"You're absolutely right!" has become a meme, but it's not what you want when you're workshopping ideas.

This is the best feature of 4.5 for me so far.

Not a coder? This interactive map of median age in Phoenix can be created in just a few lines of R code.

Plus, I've got tons of examples to get you started in the docs and in my free online book.

Load US Census Boundary and Attribute Data as tidyverse and sf-Ready Data Frames

An integrated R interface to several United States Census Bureau APIs (<https://www.census.gov/data/developers/data-sets.html>) and the US Census Bureau's geographic boundary files. Allows R users to return Census and ACS data as tidyverse-ready data frames, and optionally returns a list-column with feature geometry for mapping and spatial analysis.

Feeling stuck with data.census.gov unavailable during the government shutdown?

Now's a great time to try out tidycensus.

The decennial Census and American Community Survey are at your fingertips - and get pre-joined geographies for mapping.

The @maprva.org surveillance map, ported to #Rstats using mapgl, osmdata, sf, and dplyr.

Not 1:1 in terms of Ultra/Mapbox GL JS -> R, but pretty close!

looking at the code, that's absolutely do-able in mapgl!

Learn about the new {pmtiles} R package, which helps you create, serve, and view PMTiles from R - all starting with the sf objects you're already using.

Paired with {mapgl}, PMTiles puts massive spatial data visualization in the hands of R users - like this interactive 3D map.

New post: mapping 650,000+ Census blocks in Texas in 3D with PMTiles

You've heard me talk about @protomaps.com's PMTiles for a while and how transformative this tech can be for geospatial visualization.

In my latest post, you'll learn how to use PMTiles in R.

Your company's affordable production mapping stack:

- R + Shiny (seriously)
- PMTiles for massive data visualization;
- Cloudflare R2 Workers for serving data securely;
- MapLibre for your maps;
- Docker + a cloud service (I like Fly.io)

yeah, I think so.

I don't send anything to conda-forge; that looks like the pmtiles Python package maintained by the PMTiles author

Real-time spatial analysis in your R Shiny apps?

The {mapgl} package - and its TurfJS integration - make it possible.

Watch as Voronoi polygons instantly update on marker drag.

redistio now uses @kylewalker.bsky.social's mapgl for interactive redistricting map editing!

redistio is an #rstats package that uses Shiny to draw redistricting maps locally.

Unlike other district editors, this provides access to our simulation algorithms, interactively!

Short demo:

Why not?

R-Universe by @rOpenSci is an extremely useful project.

My latest R package, {pmtiles}, is not a good fit for CRAN as it bundles a pre-compiled Go library.

With R-Universe, I was able to get installable cross-platform binaries built in hours!

you'd need tippecanoe installed: github.com/felt/tippeca...

once that's set up, you'll need to convert your shapefile to GeoJSON (QGIS can do that)

Or use R with my package; read in the shapefile with st_read(), then use the pm_create() function

Many thanks and credit to @protomaps for creating such an empowering tool.

Try out the package and let me know what you think!

Install: `pak::pak("walkerke/pmtiles")`

- Utilities for serving PMTiles, both directly (for use with PMTiles.js and {mapgl}'s add_pmtiles_source() ) as well as via ZXY endpoints for use with any library that supports it.

- A PMTiles viewer for inspecting PMTiles on an interactive map in your favorite R IDE. View local PMTiles files and remotely-hosted ones with the help of {mapgl}.

- R bindings for the go-pmtiles library; inspect tiles, extract regions from tiles, and a whole lot more.
