Parameter Descriptions

Description

Descriptions of the parameters and a typical return value for the provided functions.

Arguments

bbox

A vector of four numbers indicating bounding box to limit output features to, e.g. c(minLon, minLat, maxLon, maxLat).

blue_line_key

A positive whole number of the stream blue line key.

collection_id

A character string of the collection id.

downstream_route_measure

A positive number of the river metre.

end_measure

An integer of the distance in meters upstream from the river mouth to end at.

epsg

A positive whole number of the epsg to transform features to.

function_id

A character string of the function id.

filter

A named vector or list of the filter(s) to apply, where the list names correspond to column names and the list values correspond to the desired value, e.g. list(gnis_name = "Sangan River").

interval_length

An integer of the interval distance in meters.

limit

A positive whole number indicating the maximum number of features to return.

offset

A positive whole number indicating the offset of start of returned results.

parameters

A named list of the parameters and values for a specific function.

properties

A vector of strings of the column names to include. If NULL (default), all columns are retained.

sortby

A string that sorts the response items by a property. Default is ascending but property name can be prepended with '-' to indicate descending.

groupby

A string of the property name (i.e., column name) to group response features by. This would typically be used with an aggregate transform function.

srid

A positive whole number of the epsg of the coordinates.

start_measure

An integer of the distance in meters upstream from the river mouth to start from.

tolerance

A number of the tolerance in m.

transform

A character vector with the name of the valid transform function followed by the parameter values (e.g. c("ST_Simplify", 100))

x

A number of the x coordinate.

y

A number of the y coordinate.

nocache

A flag specifying whether or not to cache results.

Value

An sf object.
