Combines all of routines in rCAT to process multiple species for AOO, EOO etc.
1 | ConBatch(taxa, lat, long, cellsize, project2gether)
|
taxa |
field which defines a list of species or taxa |
lat |
field which defines the latitude set of points |
long |
field which defines the longtitude set of points |
cellsize |
cell length in metres used to for AOO projection N.B. IUCN recommend 2000 m (ie 2 km) |
project2gether |
TRUE or FALSE, TRUE all data is projected together using the centre of all latitudes and longtitudes. FALSE each species is projected separately. Default = FALSE |
This function expects a list of taxa and latitudes and longitudes.ie
species_w | 85.388000 | 84.33100 |
species_w | -45.467000 | 88.41500 |
species_w | -34.339000 | -149.52600 |
species_x | -29.620000 | 79.11900 |
species_x | 33.409000 | -33.94700 |
species_x | 64.692000 | -149.18900 |
species_y | 2.308000 | -140.21900 |
species_y | 41.452000 | -3.65600 |
species_y | -30.475000 | -129.99600 |
etc
dataframe with; taxa ,Number of points, Area of the enclosing recetangle, EOO Area in km2, AOO area in km2, EOO IUCN category, AOO IUCN category
taxa | NOP | MER | EOOkm2 | AOO2km | EOOcat | AOOcat | |
1 | species x | 14 | 918562.259811711 | 585915.607417865 | 14 | LC | EN |
2 | species y | 124 | 1717224.64389286 | 634149.482670821 | 124 | LC | EN |
3 | species z | 61 | 22622717.2314339 | 17839113.1220552 | 61 | LC | EN |
4 | species w | 1130 | 509390660.388499 | 506445176.073246 | 1130 | LC | VU |
Has a switch to either project all data as a whole or each taxa separately. I would suggest you use this switch if data is all from a simlar area (i.e. all from one country/region)
