Santa Clara CA Lidar 2023 - 2D Building Footprint

vector data
<DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>Product: 2D Building Footprint in shapefile format. Geographic Extent: Santa Clara, California, covering approximately 1,754 square miles. Dataset Description: The lidar project called for the Planning, Acquisition, processing and derivative products of lidar data to be collected at a nominal pulse spacing (NPS) of 0.35 meters. Project specifications are based on the U.S. Geological Survey National Geospatial Program Base Lidar Specification. The data was developed based on a horizontal projection/datum of NAD83(2011) California Zone 3, Feet and vertical datum of NAVD88 (GEOID18), Feet. Lidar data was delivered as processed Classified LAS 1.4 files, formatted to 13 individual 2500 ft x 2500 ft tiles clipped to the DPA, as tiled intensity images, as tiled DTMs, as tiled DEMs, and as tiled DSMs; all tiled to the same 2500 ft x 2500 ft schema. Ground Conditions: Lidar was collected in late 2022, while no snow was on the ground and rivers were at or below normal levels. In order to post process the lidar data to meet task order specifications and meet ASPRS vertical accuracy guidelines, Sanborn Map Company, Inc., established a total of 42 ground control points that were used to calibrate the lidar to known ground locations established throughout the project area. An additional 129 independent accuracy check points, 74 in bare earth and urban landcovers (74 NVA points), 55 in tall grass and brushland/low trees categories (55 VVA points), were used to assess the vertical accuracy of the data. These check points were not used to calibrate or post process the data.</SPAN></P></DIV></DIV></DIV>
To acquire detailed surface elevation data for use in conservation planning, design, research, floodplain mapping, dam safety assessments and elevation modeling, etc. Classified LAS files are used to show the manually reviewed bare earth surface. This allows the user to create Intensity Images, Breaklines and Raster DEM. These lidar point cloud data were used to create intensity images, 3D breaklines, 2D building footprints, 3D building models, and hydro-flattened DTMs as necessary.

Data covers the full area specified for this project. Buildings are based on classified building point cloud data, 2D building outline was automatically extracted with height attributed. 3D building model was then automatically extracted based on 2D building outline and the classified building point cloud. Manual edits are involved only for obvious errors.
All files are inspected to ensure that they conform to the specified file naming conventions, all files load in their correct geographic position, all files conform to the project specifications for file standard and content.
Building Processing: Vector building data is based on the classified building point cloud data, 2D building outline was automatically extracted with height attributed. 3D building model was then automatically extracted based on 2D building outline and the classified building point cloud.
