elevation {vegsoup} | R Documentation |
Get topographic height information from the SRTM3 data set using package geonames and assign a column named 'elevation'
to the sites data. If such a column name already exists, the method append a column named 'elevation.srtm'
to prevent overwriting of already existing columns.
If the SRTM3 data set has missing values a zero elevation is returned for that coordinate.
Depending of the size of the input object (number of plots), the query to the genonames server may take a while to complete?
