get_meetnetten_visits: Query visit data from Meetnetten

In inbo/inbodb: Connect to and Retrieve Data from Databases on the INBO Server

Query visit data from Meetnetten

Description

This function queries the Meetnetten database for visit data (data about a counting event) for a specified monitoring scheme or for all monitoring schemes within a specified species group. When no monitoring scheme or species group is specified, the visits of all monitoring schemes are returned.

Usage

get_meetnetten_visits(
  connection,
  scheme_name = NULL,
  species_group = NULL,
  collect = FALSE
)

Arguments

connection	dbconnection with the database 'S0008_00_Meetnetten' on the inbo-sql08-prd.inbo.be server.
scheme_name	the name of the monitoring scheme for which you want to extract visit data.
species_group	the name of the species group for which you want to extract visit data.
collect	If FALSE (the default), a remote tbl object is returned. This is like a reference to the result of the query but the full result of the query is not brought into memory. If TRUE the full result of the query is collected (fetched) from the database and brought into memory of the working environment.

Value

A remote tbl object (collect = FALSE) or a tibble dataframe (collect = TRUE) with following variables:

• species_group

• scheme: the name of the monitoring scheme

• protocol: the protocol used

• location: the name of the location

• visit_id: unique id for a count event

• validation_status: validation status of the visit (visits that are validated and not approved are not provided)

  • 10: visit not validated

  • 100: visit validated and approved

• start_date: the start date of the visit

• start_time: the start time of the visit

• end_date: the end date of the visit

• end_time: the end time of the visit

• date_created: the date at which the data was imported in the database

• visit_status: the status of the visit (determined by the observer) using following categories:

  • conform protocol: the protocol was applied

  • weersomstandigheden waren ongunstig: weather conditions were unfavourable

  • telmethode uit handleiding niet gevolgd: the protocol was not applied

  • geen veldwerk mogelijk - locatie ontoegankelijk: counting was not possible because the location is inaccessible

  • geen veldwerk mogelijk - locatie is ongeschikt voor de soort: counting was not possible because the location is not suitable for the species

• for_analysis: whether the data is suited for analysis (determined by the validator)

• for_targets: every year targets are set in terms of the number of locations that have to be counted per monitoring scheme; when for_targets = TRUE the visit contributes to these targets

• notes: notes by the observer
