We’ll run the LAS Dataset to Raster geoprocessing tool again but with different parameters as below to create a Digital Surface Model (DSM) showing elevation of objects.This time set the Filter to First Return. Again, select your LAS dataset in the dropbox box on the LAS Dataset toolbar.This will ensure you only create a DTM for your area of interest rather than spending hours creating a countywide DTM. VERY IMPORTANT: Click on the Environments button and set the Processing Extent to the Same as your Data_Extent layer.Interpolation Type: Triangulation with NATURAL_NEIGHBOR interpolation method and NO_THINNING.Output Raster: Save to your staging file geodatabase as DTM.Run the LAS Dataset to Raster geoprocessing tool (Under Conversion Tools - To Raster) using the following options to create a Digital Terrain Model (DTM) showing the elevation of only the ground.Select your LAS dataset in the dropdown box in the LAS Dataset toolbar, click on the Filters box and select Ground.Add the LAS dataset to your MXD and enable the LAS Dataset toolbar.Create a new LAS Dataset in the staging folder.Make sure the 3D Analyst extension is enabled in ArcMap by going to Customize - Extensions and making sure the 3D Analyst extension is checked.You don’t have to fill in the attribute table to move on. You may want to symbolize the points using a 2D tree symbol. Add the new Trees feature class to your MXD and use aerial imagery to place tree locations.You may want to Import fields from the trees feature class in the Redlands Redevelopment Tutorial. Since we don’t have an existing Tree inventory, create a new point feature class in the staging file geodatabase called “Trees”.Save the results in the staging file geodatabase. Use the Clip geoprocessing tool to clip the Roads, Parcels and Building footprints feature classes to the Data_Extent polygon.Too much data may cause performance issues. Typically this should be a small area of only a few blocks. Create a new rectangle polygon in the Data_Extent feature class and draw the box around the data you want to use in CityEngine.Add the Data_Extent feature class to your MXD and start editing.Create a new polygon feature class in the file geodatabase created in the previous step.Create a Staging File Geodatabase in the Staging folder created in the last step.Create a Staging Folder for the data to be imported into CityEngine and save the MXD in that folder.Open a new MXD and add Roads, Parcels, Building Footprints and Imagery.Roads, Parcels, Building Footprints, Imagery, 2013 LiDAR dataĮsri CityEngine 2014 (county employees should contact the GIS department for a license) Creating 3D Models in CityEngine in San Juan County, Washington Procedure Requirements
