# Poly4AT

The goal of Poly4AT is to provide user-friendly access to the [INVEKOS API](https://gis.lfrz.gv.at/api/geodata/i009501/ogc/features/v1/) for retrieving and interacting with field parcel polygons. The application simplifies querying geographic data, allowing users to easily obtain polygon information based on coordinates, even without programming skills.

Install the following packages if they are not already installed.
```r

# install.packages(c("shiny", "sf", "leaflet", "geojsonsf", "httr", "jsonlite", "shinydashboard", "DT, "leaflet.extras"))
