This function queries the the Flemish soil map attributes at a given coordinate, by using the affiliated WFS service provided by DOV. The user can pick the properties of interest. See the examples section to see how to obtain a full list of possible properties of interest. Coordinates should be given in the 'Belge 1972 / Belgian Lambert 72' (EPSG:31370) coordinate reference system. When outside the Flemish region, an NA value is given for each of the properties.

extract_soil_map_data(x_lam, y_lam, properties_of_interest)

Arguments

x_lam

The numeric value of the X coordinate in CRS 'Belge 1972 / Belgian Lambert 72' (EPSG:31370).

y_lam

The numeric value of the Y coordinate in CRS 'Belge 1972 / Belgian Lambert 72' (EPSG:31370).

properties_of_interest

A vector or properties, as a subset of these provided by the webservice (see the examples section for how to obtain the list). Default Bodemserie, Unibodemtype and Bodemtype.

Value

A data.frame with the properties as column headers.
