Optional elevation of the first cell center point (Easting). If only this elevation is defined , then all cells in the grid are assumed to have the same elevation.
xCellSize / columnWidth
Cell width of each column in the grid. The cell width is given in the unit of the coordinate system referred to in the geoDatum. Generally this is metres, but in WGS 1984 this is decimal degrees.
The xCellSize-element is used when all cells are equal in width. Please use the columnWidth-element to define cells with variable columnWidth.
yCellSize / rowHeigt
Cell height of each row in the grid. The cell height is given in the unit of the coordinate system referred to in the geoDatum. Generally this is metres, but in WGS 1984 this is decimal degrees.
The yCellSize-element is used when all cells are equal in height. Please use the rowHeight-element to define cells with variable height.
z / zBottom / zTop
Optional definition of the elevation of each point in the grid. This definition is only necessary where a datum is required in for example 3-dimensional interpolation. This may be applied in for example interpolating temperature grids in high mountain areas. Alternative uses are the display of elevation in a cross section of the Spatial Display. The bottom/top layer is only displayed if the parameter unit is meters and if the corresponding displayOptions are configured in the TimeSeriesDisplayConfig file and if the layer contains non-NaN values. The useDatum property is not used here.
Use 'z' for the average elevation, and zBottom and zTop in case a model layer needs to be defined
zMapLayerName / zBottomMapLayerName / zTopMapLayerName
Optional definition of the elevation by reference to an ASC or BIL file stored in the MapLayerFiles-directory. This definition is only necessary where a datum is required in for example 3-dimensional interpolation. This may be applied in for example interpolating temperature grids in high mountain areas. Alternative uses are the display of elevation in a cross section of the Spatial Display. The bottom/top layer is only displayed if the parameter unit is meters and if the corresponding displayOptions are configured in the TimeSeriesDisplayConfig file and if the layer contains non-NaN values. The useDatum property is not used here.
Use 'zMapLayerNAme' for the average elevation, and zBottomMapLayerName and zTopMapLayerName in case a model layer needs to be defined.
