  • (!) The first WKT literal is defective. It lists the same numbers twice and results in defective numbers with two decimal points each.
  • @Gonsco As per Missing GeoSPARQL WKT coordinate system #97, the building is located at WGS 84: 2.7414317, 41.6458244. Are the above coordinates close enough? There's a difference of 0.30,0.36 degrees. A degree is 111m along the meridians and the equator, so that's about 30m difference (the size of the building).
  • These WKT literals have a GeoSPARQL literal. As per Missing GeoSPARQL datatype #96, all WKT literals need such
