Get SLGA landscape covariate data at a point location.
get_lscape_point(
product = NULL,
poi = NULL,
buff = 0L,
buff_shp = c("square", "circle"),
stat = "median"
)Character, one of the options from column 'Short_Name' in
slga_product_info, where Type =
'Landscape'.
WGS84 coordinates defining a point of interest. Supply an sf-style point object or a length-2 numeric vector (x, y).
Length-1 integer. Use if a summarised value around a point is desired. Defaults to 0L, which returns the exact value(s) of the pixel under the `poi`. A `buff` value of 1 will return a summary of the pixels in a one-cell range, etc.
One of 'square' or 'circle'. Use with buff > 0. Defaults to 'square', in which case all values within the buffer are summarised. A circular mask is applied to the data before summarising otherwise.
Summary method applied where buff > 0. Defaults to median. Other options include mean, modal, min, max, sd, IQR, quantile, and summary.
An data.frame with requested values.
