Simple example for an XML dataset according to CityGML, the GML application schema of the SIG 3D. This dataset contains one simple building in LOD1 and LOD2 and the surrounding terrain as well as two separate appearance themes: 1.) Simple building in LOD1 2.) Simple building in LOD2 3.) Digital terrain given by a TIN. 4.) Appearance theme “summer”. 5.) Appearance theme “winter”. Please note, that appearances are explicitly linked to GML geometry objects using URIs. Since Texture objects are modelled as features (with a unique id) they can be (and in fact are) reused. This is realized using XLinks. The coordinate reference system is given in DHDN / Gauss-Krueger 3 degree (2nd zone) + normal heights above sea level (DHHN92). This system is referred to by srsName="urn:ogc:def:crs,crs:EPSG:6.12:31466,crs:EPSG:6.12:5783". Please note that the coordinates actually used in this dataset have been trimmed for clarity reasons and thus do not match this CRS. -6.0 -7.0 0.0 17.0 13.0 5.0 2007 5.0 0.0 0.0 0.0 10.0 0.0 0.0 10.0 0.0 4.0 0.0 0.0 4.0 0.0 0.0 0.0 10.0 0.0 0.0 10.0 5.0 0.0 10.0 5.0 4.0 10.0 0.0 4.0 10.0 0.0 0.0 10.0 5.0 0.0 0.0 5.0 0.0 0.0 5.0 4.0 10.0 5.0 4.0 10.0 5.0 0.0 0.0 5.0 0.0 0.0 0.0 0.0 0.0 0.0 4.0 0.0 5.0 4.0 0.0 5.0 0.0 0.0 0.0 4.0 10.0 0.0 4.0 10.0 5.0 4.0 0.0 5.0 4.0 0.0 0.0 4.0 0.0 0.0 0.0 5.0 0.0 0.0 5.0 0.0 3.0 0.0 0.0 3.0 0.0 0.0 0.0 5.0 0.0 0.0 10.0 0.0 0.0 10.0 0.0 3.0 5.0 0.0 3.0 5.0 0.0 0.0 10.0 0.0 0.0 10.0 5.0 0.0 10.0 5.0 3.0 10.0 2.5 5.0 10.0 0.0 3.0 10.0 0.0 0.0 10.0 5.0 0.0 0.0 5.0 0.0 0.0 5.0 3.0 10.0 5.0 3.0 10.0 5.0 0.0 0.0 5.0 0.0 0.0 0.0 0.0 0.0 0.0 3.0 0.0 2.5 5.0 0.0 5.0 3.0 0.0 5.0 0.0 0.0 0.0 3.0 10.0 0.0 3.0 10.0 2.5 5.0 0.0 2.5 5.0 0.0 0.0 3.0 10.0 5.0 3.0 0.0 5.0 3.0 0.0 2.5 5.0 10.0 2.5 5.0 10.0 5.0 3.0 1 Ground 1 -6.0 5.0 0.0 0.0 5.0 0.0 -6.0 9.0 0.0 -6.0 5.0 0.0 0.0 5.0 0.0 0.0 12.0 0.0 -6.0 9.0 0.0 0.0 5.0 0.0 0.0 5.0 0.0 6.0 11.0 0.0 0.0 12.0 0.0 0.0 5.0 0.0 0.0 5.0 0.0 10.0 5.0 0.0 6.0 11.0 0.0 0.0 5.0 0.0 10.0 5.0 0.0 11.0 13.0 0.0 6.0 11.0 0.0 10.0 5.0 0.0 10.0 5.0 0.0 15.0 8.0 0.0 11.0 13.0 0.0 10.0 5.0 0.0 10.0 5.0 0.0 17.0 2.5 0.0 15.0 8.0 0.0 10.0 5.0 0.0 10.0 5.0 0.0 10.0 0.0 0.0 17.0 2.5 0.0 10.0 5.0 0.0 10.0 0.0 0.0 17.0 -3.0 0.0 17.0 2.5 0.0 10.0 0.0 0.0 10.0 0.0 0.0 14.0 -7.0 0.0 17.0 -3.0 0.0 10.0 0.0 0.0 10.0 0.0 0.0 5.0 -6.0 0.0 14.0 -7.0 0.0 10.0 0.0 0.0 10.0 0.0 0.0 0.0 0.0 0.0 5.0 -6.0 0.0 10.0 0.0 0.0 0.0 0.0 0.0 -1.0 -4.0 0.0 5.0 -6.0 0.0 0.0 0.0 0.0 0.0 0.0 0.0 -5.0 0.0 0.0 -1.0 -4.0 0.0 0.0 0.0 0.0 0.0 0.0 0.0 0.0 5.0 0.0 -5.0 0.0 0.0 0.0 0.0 0.0 0.0 5.0 0.0 -6.0 5.0 0.0 -5.0 0.0 0.0 0.0 5.0 0.0 Summer 1.0 0.6 0.0 #lod1Surface ground_summer.png none -5.0 -5.0 0.05 0.0 0.0 0.066667 #ground #lod1RoofPoly1 #lod2RoofPoly1 #lod2RoofPoly2 facade.png wrap 0.0 0.0 2.0 0.0 2.0 1.0 0.0 1.0 0.0 0.0 2.0 0.0 4.0 0.0 4.0 1.0 2.0 1.0 2.0 0.0 -0.4 0.0 0.0 1.0 0.0 0.0 0.3333 0.0 0.0 0.0 0.0 1.0 front_back_summer.png none 0.0 0.0 0.5 0.0 0.5 0.6 0.25 1.0 0.0 0.6 0.0 0.0 0.5 0.0 1.0 0.0 1.0 0.6 0.75 1.0 0.5 0.6 0.5 0.0 Winter ground_winter.png none -5.0 -5.0 0.05 0.0 0.0 0.066667 #ground #lod1RoofPoly1 #lod2RoofPoly1 #lod2RoofPoly2 front_back_winter.png none
