prism vs spatstat.geom: at a glance
What is prism?
prism rebuilds on Oregon State's new API and starts the move to cloud-optimised GeoTIFF.
prism downloads and handles PRISM climate data in R. Version 0.3.0 rewrites the package against the API Oregon State introduced in September 2025, arriving after a gap the maintainer apologises for. Normals now download as cloud-optimised GeoTIFF rather than .bil, so helper functions such as pd_plot_slice() and pd_image() do not work with them. Archives mixing old and new API data trigger a warning and a recommendation to start fresh.
What is spatstat.geom?
The geometry layer under spatstat, steadily absorbing 3D patterns and missing-data semantics
spatstat.geom holds the spatial data structures and geometric operations the rest of the spatstat family builds on — windows, tessellations, images, point patterns and the operations that move between them. Recent releases split their attention between extending those structures to three dimensions and hardening the discretisation code where polygonal geometry meets a pixel grid. 3.8-2 adds more capabilities for three-dimensional point patterns.

◆ Current state
prism downloads and handles PRISM climate data in R. Version 0.3.0 rewrites the package against the API Oregon State introduced in September 2025, arriving after a gap the maintainer apologises for. Normals now download as cloud-optimised GeoTIFF rather than .bil, so helper functions such as pd_plot_slice() and pd_image() do not work with them. Archives mixing old and new API data trigger a warning and a recommendation to start fresh.
◆ Where it's heading
The package is mid-migration on two axes at once: the API endpoint, which is done, and the file format, where only normals have moved to COG while everything else still fetches .bil. The stated plan is to take the whole package to COG. Until that lands, capability is split — data downloads fine, but the plotting and slicing helpers only cover the old format.
◆ Prediction
The next substantive release should extend COG downloads beyond normals and restore the helper functions against that format, closing the gap this release opened.

The geometry layer under spatstat, steadily absorbing 3D patterns and missing-data semantics
◆ Current state
spatstat.geom holds the spatial data structures and geometric operations the rest of the spatstat family builds on — windows, tessellations, images, point patterns and the operations that move between them. Recent releases split their attention between extending those structures to three dimensions and hardening the discretisation code where polygonal geometry meets a pixel grid. 3.8-2 adds more capabilities for three-dimensional point patterns.
◆ Where it's heading
Two threads run through this window. The first is a family-wide push into 3D that originated in the simulation package and has now reached the geometry layer. The second is a slower semantic change: 3.5-0 introduced missing or unavailable (NA) spatial objects, and 3.6-0 followed with more facilities for handling them, meaning an absent window or image became a representable value rather than an error. Around both, the plotting and discretisation code accretes steadily — nonlinear colour maps, plot backgrounds, transparency control, signed distance transforms, and repeated attention to boundary pixels.
◆ Prediction
Expect the 3D surface here to keep filling in behind the simulation package rather than leading it, given that 3.8-2 follows the 3D simulation release by two months. The entries give no indication that the NA work is finished, since it has already spanned two releases.
