In VicmapR: Access Victorian Spatial Data Through Web File Services (WFS)

Get Column Information

Description

geom_col_name returns a single value for the name of the geometry column for the WFS layer selected in the vicmap_promise object (e.g. SHAPE). This column will become the geometry column when using collect(). feature_cols() provides a vector of all column names for the WFS layer selected in the vicmap_promise object and get_col_df() returns a data.frame with the column names and their XML schema string datatypes.

Usage

geom_col_name(x)

feature_cols(x)

get_col_df(x)

Arguments

x	object of class vicmap_promise

Value

character/data.frame

Examples

# Return the name of the geometry column
vicmap_query(layer = "open-data-platform:hy_watercourse") %>% 
  geom_col_name()
 

# Return the column names as a character vector
vicmap_query(layer = "open-data-platform:hy_watercourse") %>% 
  feature_cols()
   

# Return a data.frame of the columns and their XML schema string datatypes
try(
vicmap_query(layer = "open-data-platform:hy_watercourse") %>% 
  get_col_df()
  )
