bcdc_describe_feature: Describe the attributes of a Web Feature Service

Description

Describe the attributes of column of a record accessed through the Web Feature Service. This can be a useful tool to examine a layer before issuing a query with bcdc_query_geodata.

Usage

bcdc_describe_feature(record)

Value

bcdc_describe_feature returns a tibble describing the attributes of a B.C. Data Catalogue record. The tibble returns the following columns:

• col_name: attributes of the feature

• sticky: whether a column can be separated from the record in a Web Feature Service call via the dplyr::select method

• remote_col_type: class of what is return by the web feature service

• local_col_type: the column class in R

• column_comments: additional metadata specific to that column

Arguments

record

either a bcdc_record object (from the result of bcdc_get_record()), a character string denoting the name or ID of a resource (or the URL) or a BC Geographic Warehouse (BCGW) name.

It is advised to use the permanent ID for a record or the BCGW name rather than the human-readable name to guard against future name changes of the record. If you use the human-readable name a warning will be issued once per session. You can silence these warnings altogether by setting an option: options("silence_named_get_data_warning" = TRUE) - which you can set in your .Rprofile file so the option persists across sessions.
