In rLFT: Processing Linear Features

#' An example sf object outlining boundaries of a group of islands in Alaska cast as LINESTRING.
#'
#' A dataset with coordinates (x, y) of 37 linear features with a geometry type of LINESTRING and
#' a projected coordinate system (aea). These particular features represent several small islands in Alaska.

"shpObject"


#' An example sf object outlining boundaries of a group of islands in Alaska in the lat/lon CRS.

#' An example sf object outlining boundaries of a group of islands in Alaska cast as POLYGON.
#'
#' A dataset with coordinates (x, y) of 37 features with a geometry type of POLYGON and
#' a projected coordinate system (aea). These features represent the same data as 'shpObject' but this sf
#' object has been cast to be of geometry type POLYGON. There are also inner polygons on some features.
