Modernizing Rspatial: Changes in OSGeo FOSS Libraries and the Evolving RSpatial Package Ecosystem

PROJ, GEOS and GDAL have changed a lot in the last 5 years. In addition, M1 has arrived, as has UCRT for Windows, causing a lot of churn in Rspatial package maintenance. Further, three packages maintained by me: rgdal, rgeos, and maptools, are to retire during 2023. There are more modern alternatives and developer effort is better applied to supporting them. The raster package already uses terra for access to shared FOSS foundations. The sp package is being rebased to use sf, so it will remain. The talk will report on progress so far, the current status of the evolution project, and prospects for completion this year.
