lc_get_data: Get LakeCat data

Description

Function to return LakeCat metrics using the StreamCat API. The function allows a user to get specific metric data aggregated by area of interest, returned by comid(s), hydroregion(s), state(s), or county(ies).

Usage

lc_get_data(
  comid = NULL,
  metric = NULL,
  aoi = NULL,
  showAreaSqKm = NULL,
  showPctFull = NULL,
  state = NULL,
  county = NULL,
  region = NULL,
  conus = NULL,
  countOnly = NULL
)

Value

A tibble of desired StreamCat metrics. If data are missing for all rows of a given metric, then the column for that metric will not exist. If data are missing for only some rows, then they will be specified with NA.

Arguments

comid

Return metric information for specific COMIDs. Can be a comma-delimited list, a character vector, or any object that can be coerced to a comma-delimited list with paste. One of comid, county, state, or region is required unless conus='true'. Syntax: comid=<comid1>,<comid2>

metric

Name(s) of metrics to query. Must be character string with comma-delimited list of metrics. Not case-sensitive. Syntax: name=<name1>,<name2>

aoi

Specify the area of interest described by a metric. By default, all available areas of interest for a given metric are returned. Case-sensitive. Syntax: areaOfInterest=<value1>,<value2> Values: catchment|watershed|

showAreaSqKm

Return the area in square kilometers of a given area of interest. The default value is false. Values: true|false

showPctFull

Return the pctfull for each dataset. The default value is false. Values: true|false

state

Return metric information for COMIDs within a specific state. Use a state's abbreviation to query for a given state. One of comid, county, state, or region is required unless conus='true'. If specified and valid, comid and county are ignored. Case-sensitive. Syntax: state=<state1>,<state2>

county

Return metric information for COMIDs within a specific county. Users must use the FIPS code, not county name, as a way to disambiguate counties. One of comid, county, state, or region is required unless conus='true'. If specified and valid, comid is ignored. Syntax: county=<county1>,<county1>

region

Return metric information for COMIDs within a specified hydroregion. Hydroregions are specified using full name i.e. 'Region01', 'Region03N', 'Region10L' One of comid, county, state, or region is required unless conus='true'. If specified and valid, comid, county, and state are ignored. Case-sensitive. Syntax: region=<regionid1>,<regionid2>

conus

Return all COMIDs in the conterminous United States. Character string (Not case-sensitive) or logical. The default value is false. If true, comid, county, state, and region are ignored. Values: true|false

countOnly

Return a CSV containing only the row count (ROWCOUNT) and the column count (COLUMNCOUNT) that the server expects to return in a request. The default value is false. Values: true|false
