This will grid the calculated NDVI value.
NDVI (vegetation) - This requires point cloud data with RGB and also NIR values. Color (RBG+NIR) - This will create an orthoimage of RGB colors plus NIR as 4-band. Color (RGB+Intensity) - This will create an orthoimage of RGB colors plus Intensity as 4-band. This is calculated using the color of the highest point in the point cloud at each grid spacing. Color (RGB) - This will create an orthoimage from the RGB values of the point cloud. For more information about the height above ground calculation for Lidar data see Color Lidar by Height Above Ground In the output terrain grid, a value of 0 will represent ground. Height Above Ground - Save the calculated height above ground value as a terrain grid, rather than the absolute elevation. The intensity of the return is due to the reflectivity of the surface struck by the pulse. The intensity value in a Lidar point cloud measures the strength of the signal return to the sensor from the Lidar pulse. Intensity Values - Create a raster grid of the intensity values. This will create a terrain grid of the elevation values. Elevation Values - This is the default grid type. With the Lidar Module, grids may also be createdįrom additional attributes of the 3D points. This option will appear when gridding Lidar data. This option is disabled when gridding by Elevation values. 
Vertical Units - Specify the output elevation units for the grid.ĭata Type - This option controls whether generated color grids use 8-bit or 16-bit values. The Elevation Grid creation options will provide a larger dialog with additional options when Lidar Data is loaded.ĭescription - Layer name and description for the resulting Elevation Grid. Tab to specify that your data should be tiled in sections. Vector data as well as what portion of the selected overlays to use whenĬreating the elevation grid. This tool is also available by right-clicking on layers in the Overlay Control Center, under the Analysis sub menu.Ĭonfigure how you want the elevation grid to be created using the selected Grid by choosing this option in the Analysis Menu or using the Analysis Toolbar button Create Elevation Grid from 3D Vector Data.
This includes 3D vectors, lidar and point cloud data and mesh / 3D model features.
An elevation grid can be generated from any combination of vector data loaded containing an elevation component.
