get_site: Return Site Information.

Description

Return site information from the Neotoma Paleoecological Database.

get_site returns site information from the Neotoma Paleoecological Database based on parameters defined by the user.

Usage

get_site(sitename, altmin, altmax, loc, gpid, ...)

Arguments

sitename

character string representing the full or partial site name, or an object of class dataset, dataset_list, download or download_list

altmin

Minimum site altitude (in m).

altmax

Maximum site altitude (in m).

loc

A numeric vector c(lonW, latS, lonE, latN) representing the bounding box within which to search for sites. The convention here is to use negative values for longitudes west of Grewnwich or longitudes south of the equator.

gpid

A character string or numeric value, must correspond to a valid geopolitical identity in the Neotoma Database. Use get.tables('GeoPoliticalUnits') for a list of acceptable values, or link here: http://api.neotomadb.org/apdx/geopol.htm

...

Optional additional arugments

Value

A data frame:

siteid

Unique database record identifier for the site.

sitename

Name of the site.

long

Mean longitude, in decimal degrees, for a site (-180 to 180).

lat

Mean latitude, in decimal degrees, for a site (-90 to 90).

elev

Elevation in meters.

description

Free form description of a site, including such information as physiography and vegetation around the site.

long_acc

If the site is described by a bounding box this is the box width.

Examples

#  What is the distribution of site elevations in Neotoma?
all.sites <- get_site()  #takes a bit of time.

plot(density(all.sites$elev, from = 0, na.rm=TRUE),
main = 'Altitudinal Distribution of Neotoma Sites', xlab = 'Altitude (m)', log='x')

#  Get site information from a dataset:
nw.datasets <- get_dataset(loc = c(-140, 50, -110, 65), datasettype='pollen',taxonname='Pinus*')
nw.sites <- get_site(nw.datasets)
