 ### Spatial coordinates
 
-`mobest::create_geopos()` creates an object of class `mobest_spatialpositions` which is a `tibble` that represents spatial positions. Spatial positions in mobest are always 2-dimensional coordinates in a Cartesian space. For real world coordinates that means, that they have to be transformed to a projected coordinate system (e.g. with `sf::st_transform`): mobest can not be used with longitude and latitude coordinates (also see See {ref}`Projecting the spatial data <basic:projecting the spatial data>`).

-For the interpolation fields we often want regular, spatial grids covering a specific spatial area. These can be constructed with `mobest::create_prediction_grid`, which takes an object of class `sf` with polygons in a projected coordinate system. It also yields an object of class `mobest_spatialpositions`.

 ### Spatiotemporal coordinates
 
-`mobest_spatialpositions` can be transformed to `mobest_spatiotemporalpositions` with `mobest::geopos_to_spatpos`. This function calculates the permutations of all spatial positions with a new, implicitly temporal dimension `z`. `mobest_spatiotemporalpositions` is also derived from `tibble`.

-`mobest_kernel` includes these input paramaters in the form of an R `list`. It only represents one specific kernel, though, for one specific dependent variable (e.g. an ancestry component `ac1`). To account for the fact that a mobest analysis typically involves multiple genetic dimensions `mobest::create_kernset` provides a wrapper to bundle multiple named (by the dependent variable name) kernels directly in an object of class `mobest_kernelsetting`.
