 The spatial raster data model represents the world with the continuous grid of cells (often also called pixels; Figure \@ref(fig:raster-intro-plot):A)\index{raster data model}.
 This data model often refers to so-called regular grids, in which each cell has the same, constant size -- and we will focus on the regular grids in this book only.

 On the other hand, **stars** uses some built-in functions (usually with names starting with `st_`), some existing **dplyr** functions (e.g., `filter()` or `slice()`), and also has its own methods for existing R functions (e.g., `split()` or `aggregate()`).
 
 Importantly, it is straightforward to convert objects from **terra** to **stars** (using `st_as_stars()`) and the other way round (using `rast()`).

 ## Manipulating raster objects
 
 In contrast to the vector data model underlying simple features (which represents points, lines and polygons as discrete entities in space), raster data represent continuous surfaces.

 Understanding DE-9IM strings allows new binary spatial predicates to be developed.
 The help page `?st_relate` contains function definitions for 'queen' and 'rook' relations in which polygons share a border or only a point, respectively.
-'Queen' relations mean that 'boundary-boundary' relations (the cell in the second column and the second row in Table \@ref(tab:de9emtable), or the 5th element of the DE-9IM string) must not be empty, corresponding to the pattern `F***T****`, while for 'rook' relations, the same element must be 1 (meaning a linear intersection) (see \@ref(queens)).

 Recent PROJ versions (6+) still allow use of proj-strings to define coordinate operations, but some proj-string keys (`+nadgrids`, `+towgs84`, `+k`, `+init=epsg:`) are either no longer supported or are discouraged.
 Additionally, only three datums (i.e., WGS84, NAD83, and NAD27) can be directly set in proj-string.

 Also, as outlined in the [PROJ documentation](https://proj.org/development/reference/cpp/cpp_general.html) there are different versions of the WKT CRS format including WKT1 and two variants of WKT2, the latter of which (WKT2, 2018 specification) corresponds to the ISO 19111:2019 [@opengeospatialconsortium_wellknown_2019].
