RemarksThe OIV.Inventor.Geo.SoGeoElevationGrid allows to create terrain models for local or large areas (automatically introduces correct degree of earth curvature).
The OIV.Inventor.Geo.SoGeoElevationGrid node specifies a uniform grid of elevation values within some spatial reference frame. These are then transparently transformed into a geocentric, curved-earth representation. For example, this would allow a geographer to create a height field where all coordinates are specified in terms of latitude, longitude, and elevation. The OIV.Inventor.Geo.SoGeoElevationGrid.geoSystem field is used to define the spatial reference frame and is described in 25.2.3 Specifying a spatial reference frame. The OIV.Inventor.Geo.SoGeoElevationGrid.geoGridOrigin field specifies the geographic coordinate for the south-west corner (bottom-left) of the dataset. This value should be specified as described in 25.2.4 Specifying geospatial coordinates. The OIV.Inventor.Geo.SoGeoElevationGrid.height array contains OIV.Inventor.Geo.SoGeoElevationGrid.xDimensionOIV.Inventor.Geo.SoGeoElevationGrid.zDimension floating point values that represent elevation above the ellipsoid or the geoid, as appropriate. These values are given in row-major order from west to east, south to north. When the OIV.Inventor.Geo.SoGeoElevationGrid.geoSystem is "GD", OIV.Inventor.Geo.SoGeoElevationGrid.xSpacing refers to the number of degrees of longitude between adjacent height values and OIV.Inventor.Geo.SoGeoElevationGrid.zSpacing refers to the number of degrees of latitude between vertical height values. When the geoSystem is "UTM", OIV.Inventor.Geo.SoGeoElevationGrid.xSpacing refers to the number of eastings (meters) between adjacent height values and OIV.Inventor.Geo.SoGeoElevationGrid.zSpacing refers to the number of northings (meters) between vertical height values. EXAMPLE If xDimension = n and the grid spans d units horizontally, the xSpacing value should be set to: d / (n-1). The OIV.Inventor.Geo.SoGeoElevationGrid.yScale value can be used to produce a vertical exaggeration of the data when it is displayed. By default, this value is 1.0 (no exaggeration). If this value is set greater than 1.0, all heights will appear larger than actual.
