TDWG: cleaning occurrence records using the World Geographical Scheme for Recording Plant Distributions (WGSRPD) 
TDWG (Ondo 2024) contains multiple functions to select or spatially
filter occurrence records for plant species. It combines botanical
information from hundreds of thousands of plant species from the Kew
World Checklist of Vascular Plants (WCVP) (Govaerts et al. 2021)
database with geographical information derived from The International
Working Group on Taxonomic Databases for Plant Sciences (TDWG) at
approximately “country” level and upwards. The package was used to help
identifying plants geographic ranges at broad scale and cleaning
occurrence records for 36,687 distribution models in The global
distribution of plants used by
humans (Pironon
and Ondo et al. 2024).
Make sure to have R or Rstudio installed on your machine. Some R packages need to be compiled from source, so if you are on Windows, you need to install Rtools too.
Install TDWG with the following instructions:
devtools::install_github("IanOndo/TDWG")
library(TDWG)The package is currently using the 2022 version of the WCVP database, so no the lastest updates of the taxonomy. Current developments aim at incorporating functions from the R package rWCVP (Brown et al. 2023).
