TSGenerator: Copernicus HR-VPP vegetation time-series processing

Description

TSGenerator provides a native-R workflow for acquiring, extracting, quality-assessing, and analysing vegetation time series derived from Copernicus High Resolution Vegetation Phenology and Productivity (HR-VPP) products, including Seasonal Trajectories (ST) and Vegetation Phenology and Productivity (VPP) products.

Details

The stable 2.0 API covers WEkEO acquisition, terra-based geospatial extraction, product-quality assessment, temporal completeness diagnostics, optional time-series imputation, missingness modelling, visualization, and integrated graphical workflows. Selected TSGenerator 1.x entry points are retained as deprecated compatibility wrappers or migration guards.

Main workflow

Use check_wekeo() and hda_client() to validate WEkEO access; download_st() or download_vpp() for acquisition; extract_ts() or extract_vpp() for polygon-level geospatial extraction; quality_info(), classify_quality(), summarize_quality(), and mask_quality() for product quality; temporal_plan(), summarize_missingness(), and assess_ts_quality() for temporal diagnostics; impute_ts() for optional gap filling; and model_missingness() with plot_missingness() for missingness analysis. The integrated graphical workflow is launched with runTSapp().

Column from which the quality of the time series will be determined (estimating the number of observations).

Value

A list of files where a dataframe with the results of the quality assessment and an interactive graphic are stored.


HR-VPP quality-code definitions

Description

Returns the TSGenerator definitions used to interpret current HR-VPP ST-QFLAG or VPP-QFLAG values.

Usage

quality_info(type = c("ST", "VPP"))

Arguments

type

Quality-flag family: "ST" or "VPP".

Value

A data frame describing the supported quality codes and classes.

classify_quality, summarize_quality, mask_quality


Legacy VI file renaming helper

Description

renames.image.IV() belongs to the discontinued VI workflow and is retained only as a migration guard.

Usage

renames.image.IV(...)

Arguments

...

Legacy arguments. They are accepted only so existing calls fail with explicit migration guidance.

Value

This function does not return a value; it stops with migration guidance.

Examples

## Not run: 
renames.image.IV()

## End(Not run)

renames.image.VPP

Description

Rename TIF files in a directory according to the year extracted from the name.

Usage

renames.image.VPP(...)

Arguments

...

Legacy arguments.

Details

This function searches for TIF files in a specified directory and renames them using the year extracted from the filename. The new file name shall be in the format 'yyyy.tif'.

Value

Does not return a value, but renames the TIF files in the specified directory.


Run the TSGenerator graphical interface

Description

Launches the unified TSGenerator 2.0 Shiny application. Selected 1.x/early-2.0 acquisition mini-apps remain temporarily accessible for compatibility, but new development is concentrated in the unified interface.

Usage

runTSapp(app = "TSGenerator2")

Arguments

app

Character string. Application to launch. The default, "TSGenerator2", launches the unified 2.0 interface. Compatibility options are "DownloadSTPPI" and "DownloadVPP".

Details

The unified application is a graphical layer over the public TSGenerator 2.0 API. Scientific algorithms are not reimplemented in the Shiny server. The historical standalone GAM interface has been retired; missingness modelling remains available through model_missingness() and plot_missingness().

Value

Invisibly returns the result of shiny::runApp().

See Also

model_missingness(), plot_missingness()

Other applications: runTSapp()

Examples

## Not run: 
TSGenerator::runTSapp()
TSGenerator::runTSapp("DownloadVPP")

## End(Not run)

Summarise missingness and temporal completeness

Description

Separates absent expected dates from explicit NA values and reports temporal and usable-value completeness for each series.

Usage

summarize_missingness(
  data, id_col = "ID", date_col = "Date", value_col = "Value",
  expected_step = NULL, start = NULL, end = NULL
)

Arguments

data

Input time-series data frame.

id_col, date_col, value_col

Column names identifying the series, observation date, and value.

expected_step

Expected temporal step in days; if NULL, it is inferred when possible.

start, end

Optional start and end dates restricting the summary period.

Value

An object of class tsg_missingness (also a data.frame) with one row per series. Columns are the identifier (named by id_col), start, end, expected_step_days, n_expected, n_observed_dates, n_absent_dates, n_value_na, n_usable, date_completeness, value_completeness, and missing_fraction. Counts distinguish absent expected dates from observed dates with missing values. Fractions use n_expected as the denominator and are NA when that count is zero.


Summarize HR-VPP quality flags

Description

Summarizes the distribution of HR-VPP quality flags without masking observations.

Usage

summarize_quality(x, type = c("ST", "VPP"), quality_col = "QFLAG")

Arguments

x

Quality codes, a terra::SpatRaster, or a data frame.

type

Quality-flag family.

quality_col

Column containing codes when x is a data frame.

Value

A data frame with counts and percentages by documented quality code.

See Also

quality_info, classify_quality, mask_quality


Inspect and validate a vegetation time series

Description

Validates IDs, dates, missing values, duplicate observations, and temporal regularity without modifying the series.

Usage

temporal_plan(
  data, id_col = "ID", date_col = "Date", value_col = "Value",
  expected_step = NULL, allow_duplicates = FALSE
)

Arguments

data

A data frame containing one or more time series.

id_col

Series identifier column.

date_col

Date column.

value_col

Value column.

expected_step

Optional expected temporal step in days.

allow_duplicates

Logical; allow duplicate ID-date observations.

Value

An object of class tsg_temporal_plan containing validated data and diagnostics.
