Finnish Field Parcel Retriever (FiFi) is a web application 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 plants. FiFi was developed in the Risk Assessment Unit of the Finnish Food Authority and it has been made openly available web application 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:
FiFi retrieves data from the Finnish agricultural parcel dataset ( kasvulohko ) for the year 2025, provided by the Finnish Food Authority. More details about the dataset are available here .
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.
Regional datasets that FiFi is using have been compiled from several sources:
When the locations represent outbreak sites of a pest, survey bands are created around the points using the Gamma Year approach described by EFSA (2025).
