Retrieve hydrologic data from the DBHYDRO Environmental Database
get_hydro(dbkey = NA, date_min = NA, date_max = NA, raw = FALSE, ...)
dbkey | character string specifying a unique data series.

---|---|
date_min | character date must be in YYYY-MM-DD format |
date_max | character date must be in YYYY-MM-DD format |
raw | logical default is FALSE, set to TRUE to return data in "long" format with all comments, qa information, and database codes included. |

get_hydro
can be run in one of two ways.
The first, is to identify one or more dbkeys
before-hand that
correspond to unique data series and are passed to the dbkey
argument. dbkeys
can be found by:
iterative calls to get_dbkey
(see example)
using the Environmental Monitoring Location Maps (https://www.sfwmd.gov/documents-by-tag/emmaps)
using the DBHYDRO Browser (http://my.sfwmd.gov/dbhydroplsql/show_dbkey_info.main_menu).
The second way to run get_hydro
is to specify additional
arguments to ...
which are passed to get_dbkey
on-the-fly.
By default, get_hydro
returns a cleaned output where metadata
(station-name, variable, measurement units) is wholly contained in the column
name. This is accomplished internally by the clean_hydro
function. If additional metadata such as latitude and longitude are desired
set the raw
argument to TRUE
.
