When the publishing process is complete, a notification appears at the bottom of the pane. Next, you will check how accurate they are. You have created a 3D building footprints layer with roof form information in the attributes. Now that you have the buildings created, you will check how closely they match the lidar data. For now, you don't need to worry about it.
This field is used for manually editing roof forms that were incorrectly extracted. A value of 1 will rotate the roof counterclockwise 90 degrees, while a value of 2 will rotate it 180 degrees.
You will also open an ArcGIS Pro task to take you through the workflow step by step.
Download the data and deploy the solutionīefore you begin, you must download data supplied by the City of Portland and deploy the ArcGIS Solutions 3D Basemaps.
The links change frequently, so just search for ArcGIS Solutions in any web browser. You can visit the ArcGIS Solutions page for more information. Then, you will convert the point cloud into raster datasets that show the elevation of the area. After downloading the project and data, you will convert raw lidar data of the Portland neighborhood into a 3D point cloud (LAS) dataset that shows where light from the scanner struck objects, including building rooftops. You will use an ArcGIS Pro project downloaded from the solutions page that contains the 3D Basemaps solutions tools and workflows specific to local government municipal development. One of the best ways to determine the heights of a large number of surfaces is with lidar, a laser scanning technology that can cover large areas. To create 3D buildings with detailed roof forms and accurate heights, you must first know what those forms and heights are.
