Interactive Area of Habitat (AOH) map for one species

Builds a leaflet map of the terrestrial Area of Habitat: the suitable land-cover classes within the EOO, optionally restricted to an elevation band, drawn as a single green overlay together with the EOO hull and the occurrence points. It is the map companion to calc_aoh and uses the same suitable-class and elevation definitions, so the map shows exactly the area calc_aoh() measures.

Usage

map_aoh(
  assessment,
  species = NULL,
  suitable_groups = "natural",
  suitable_codes = NULL,
  elev_min = NA,
  elev_max = NA,
  z = 9,
  elev_src = NULL,
  src = NULL,
  max_pixels = 800,
  lang = c("pt", "en")
)

Arguments

assessment

A geoconv_assessment from assess_species.

species

Species name. NULL (default) uses the first.

suitable_groups

Conservation group(s) counted as suitable habitat (default "natural"). Ignored when suitable_codes is given.

suitable_codes

Optional integer land-cover class codes counted as suitable, overriding suitable_groups.

elev_min, elev_max

Elevation band in metres (NA leaves that side open; both NA skips the elevation mask).

z

Terrain-tile zoom for elevatr (default 9).

elev_src, src

Optional DEM and land-cover overrides (path/URL).

max_pixels

Display pixel budget for the land-cover read (default 800).

lang

"pt" (default) or "en" for the legend labels.

Value

A leaflet widget, or a base map with just the points/EOO when the land cover cannot be read.

Details

Suitable habitat is, by default, the natural conservation group of the land-cover legend; pass suitable_groups (one or more groups) or suitable_codes (specific land-cover class codes, e.g. the classes that make ecological sense for the species) to change it. When an elevation band is given, an elevation model read over the EOO (via elev_src or the optional elevatr package) masks out the habitat outside [elev_min, elev_max].
