spenv

spenv - add environmental data to spatial data

See the Wiki for some documentation.

Package API:

• sp_mutate - get env data for occ data input - not ready yet
• sp_extract_gridded - extract env gridded data
• sp_extract_pt - extract env point data
• sp_query - query for env data - not ready yet
• find_locs - find locations/stations/etc. based on occ data input - internal fxn used in sp_mutate

Install

devtools::install_github("ropenscilabs/spenv")

library("spenv")

Example: pt env data

file <- system.file("examples", "obis_mola_mola.csv", package = "spenv")
dat <- read.csv(file)
head(dat)

res <- sp_extract_pt(x = dat[1:10,], radius = 100)
res[[1]]

Example: gridded env data

library("spocc")
res <- occ(query = 'Mola mola', from = 'obis', limit = 200)
res_df <- occ2df(res)
out <- sp_extract_gridded(res_df)

## Assuming 'longitude' and 'latitude' are longitude and latitude, respectively
## Loading required namespace: ncdf4

head(out)
