🌍 The {terra} documentation now clearly shows which calculations for longitude/latitude data use ellipsoidal algorithms (instead of treating the data as projected).

@nrennie.bsky.socialIt's October 1st which means there's only 1 month until the #30DayMapChallenge 🗺️
@jakubnowosad.com📊 Visualization for Social Data Science is an open online book by Roger Beecham on using visualization and statistics to explore social science data.
(It also includes many great maps!)

@josiah.rs@nowosad.fosstodon.org.ap.brid.gyWant to work with the AlphaEarth Embedding data from R? 🛰️🌍
Felipe Carlos has developed an R package that makes it easier to search and retrieve AlphaEarth embeddings for your area of interest.

@mel-likes-maps.bsky.socialWhenever a dataset has location info, I like to start with a map.
This week’s #TidyTuesday data tracks urban green space since 1990 — and it’s global. First cut looks like it is trending toward less green area per person worldwide. #rstats #dataviz #rspatial
@cd-newton.hachyderm.io.ap.brid.gyAny #rspatial folks ever encountered an issue like this with leaflet.extras when using addSearchFeatures()? The zoom parameter doesn’t seem to work as expected when multiple groups with the same geometry are used, but seems fine with different geoms […]
@weare.rladies.orgMapping projects often stall on missing licenses when collaborators don't have the same software. This year I've been using the sf package: open source, and I can share my work with anyone. What's your open source GIS stack? sf: [https://r-spatial.github.io/sf/](r-spatial.github.io/sf/) #rspatial
@weare.rladies.orgAt work I use R, Python, and ArcGIS to run spatial analysis and make maps. 🗺️ #rspatial
@josiah.rsLoveeee seeing {h3o} being used for new use cases!!
@jakubnowosad.comA new R package for redistributing counts to flexible spatial grids 🗺️
Christopher D. Higgins’ `{pycnogrid}` implements pycnophylactic interpolation for H3, A5, S2, ISEA, raster, and local hexagonal grids, while preserving the original totals.
