  In recent years, with the advent of the web of data, a growing number of
national mapping agencies tend to publish their geospatial data as Linked Data.
However, differences between traditional GIS data models and Linked Data model
can make the publication process more complicated. Besides, it may require, to
be done, the setting of several parameters and some expertise in the semantic
web technologies. In addition, the use of standards like GeoSPARQL (or ad hoc
predicates) is mandatory to perform spatial queries on published geospatial
data. In this paper, we present GeomRDF, a tool that helps users to convert
spatial data from traditional GIS formats to RDF model easily. It generates
geometries represented as GeoSPARQL WKT literal but also as structured
geometries that can be exploited by using only the RDF query language, SPARQL.
GeomRDF was implemented as a module in the RDF publication platform Datalift. A
validation of GeomRDF has been realized against the French administrative units
dataset (provided by IGN France).
