Finnish Field Parcel Retriever (FiFi): A tool for retrieving field parcel data needed in statistical assessment and planning of quarantine pest surveys
Year: 2026
Type: software
Abstract: This release provides the source code for the web application 'Finnish Field Parcel Retriever' (FiFi), which is available at: https://fifi-retriever.2.rahtiapp.fi/ .FiFi is a web app for retrieving data on the distribution of crops in Finland to support the statistical assessment and planning of detection and delimiting surveys for pests of agricultural and horticultural crops. The app was developed in the Risk Assessment Unit of the Finnish Food Authority and it has been made openly available through the Rahti container service provided by CSC – IT Center for Science, Finland. The FiFi web application is implemented in R version 4.4.2 (R Core Team 2024) using the following R packages: shiny (Chang et al. 2022) DT (Xie et al. 2024) htmltools (Cheng et al. 2024) leaflet (Cheng et al. 2024) leaflet.extras (Gatscha et al. 2024) leaflet.extras2 (Gatscha 2025) memoise (Wickham et al. 2021) RColorBrewer (Neuwirth 2022) sf (Pebesma 2018; Pebesma & Bivand 2023 shinybusy (Meyer & Perrier 2024) shinyhelper (Mason-Thom 2019) shinyMatrix (Neudecker 2024) shinythemes (Chang et al. 2021) shinyWidgets (Perrier et al. 2025) terra (Hijmans 2025) yaml (Garbett et al. 2024) FiFi retrieves data from the Finnish agricultural parcel dataset (kasvulohko) for the year 2025, provided by the Finnish Food Authority. The original dataset was provided as a GeoPackage. For use within FiFi, it was converted into the FlatGeobuf format, and attribute fields and crops not needed for the planning of official plant health surveys in Finland were removed. This release does not include the agricultural parcel dataset. Users must download it separately from the Finnish Food Authority's open data repository: https://www.ruokavirasto.fi/en/about-us/published-datasets/spatial-data-sets/. However, the preprocessing script used to convert the data into FlatGeobuf format is included in this release. Regional datasets that FiFi is using have been compiled from several sources: Data on the Centres for Economic Development, Transport and the Environment and on the Regions were obtained from Statistics Finland (2025a; 2025b). The regional data were further modified to match the Economic Development Centres in Finland Data on municipalities were obtained from the National Land Survey of Finland (2025). Data on NUTS (Nomenclature of Territorial Units for Statistics) areas were retrieved from Eurostat (2024). Climate data representing the recent distribution (1991–2020) of Köppen–Geiger climate types in Finland were sourced from Beck et al. (2023) at a spatial resolution of 0.1° (approximately 11 km at the equator). These regional datasets are not included in this release. Users must download them separately from their original sources.
