mappingAS: Range Metrics and MapBiomas Habitat Conversion

A GeoCat-style toolkit for IUCN Red List Criterion B screening. It imports species occurrence points from XLSX, CSV, or shapefile inputs, computes the Extent of Occurrence (EOO, minimum convex polygon) and the Area of Occupancy (AOO, 2 km grid), and quantifies the percentage of converted (anthropic) versus remaining natural habitat inside both the EOO and the AOO using the most recent MapBiomas land-use/land-cover collection.

Main functions

read_occurrences

Import points from csv/xlsx/shapefile.

assess_species

Full pipeline (EOO, AOO, conversion).

calc_eoo, calc_aoo

Range metrics only.

summarise_conversion

Convert class areas to % converted.

map_species, plot_conversion

Visual output.

run_app

Launch the Shiny GUI.

MapBiomas backends

backend = "local" (default) reads a windowed crop of the national GeoTIFF via GDAL /vsicurl/ (no Google Earth Engine account needed). backend = "gee" uses rgee server-side reductions for very large ranges.
