Split all geotraces of a submission tibble into their components.

Usage

handle_ru_geotraces(
  data,
  form_schema,
  wkt = FALSE,
  odkc_version = get_default_odkc_version(),
  verbose = get_ru_verbose()
)

Arguments

data

Submissions rectangled into a tibble. E.g. the output of

ruODK::odata_submission_get(parse = FALSE) %>%
ruODK::odata_submission_rectangle(form_schema = ...)

form_schema

The form_schema for the submissions. E.g. the output of ruODK::form_schema().

wkt

Whether geofields are GeoJSON (if FALSE) or WKT strings (if TRUE), default: FALSE.

odkc_version

The ODK Central version as a semantic version string (year.minor.patch), e.g. "2023.5.1". The version is shown on ODK Central's version page /version.txt. Discard the "v". ruODK uses this parameter to adjust for breaking changes in ODK Central.

Default: get_default_odkc_version or "2023.5.1" if unset.

Set default get_default_odkc_version through ru_setup(odkc_version="2023.5.1").

See vignette("Setup", package = "ruODK").

verbose

Whether to display debug messages or not.

Read vignette("setup", package = "ruODK") to learn how ruODK's verbosity can be set globally or per function.

Value

The submissions tibble with all geotraces retained in their original format, plus columns of their first point's coordinate components as provided by split_geotrace.

Details

For a given tibble of submissions, find all columns which are listed in the form schema as type geotrace, and extract their components. Extracted components are longitude (X), latitude (Y), altitude (Z, where given), and accuracy (M, where given) of the first point of the geotrace.

The original column is retained to allow parsing into other spatially enabled formats.
