Name: Building Footprints

Display Field: NOTES

Type: Feature Layer

Geometry Type: esriGeometryPolygon

Description: Building footprint geometry and height attributes were extracted from 2010 ARRA LiDAR point data using ArcGIS 10 and Qcoherent's LP360 Extractor module. Feature attributes are described in the table below. All units are feet. Further documentation of data and workflow are available on request to AMBAG.notes50 char. text field used for feature commentsht_minMinimum height derived as [Minimum LiDAR point elevation - DEM ground elevation]ht_maxMaximum height derived as [Maximum LiDAR point elevation - DEM ground elevation]ht_source10 char. text field used to indicate which elevation source was used to record building heightDEMDEM ground elevation for a representative point within each building featurendsmAlternate building height derived from the nDSM layer, like above, sampling from a representative point within each building featureExtent25 char. text field describing the community/region or collection of tiles that the feature was processed withinpntCntnumber of LiDAR points classified as 'Building' within the feature polygonELAVAverage elevation of LiDAR points classified as 'Building' within the feature polygonELMNMinimum elevation of LiDAR points classified as 'Building' within the feature polygonELMXMaximum elevation of LiDAR points classified as 'Building' within the feature polygonELSDStandard Deviation of elevation of LiDAR points classified as 'Building' within the feature polygonht_aveUsed as the primary building height field. In most cases, this is value is calculated as: [ELAV – DEM]. In other cases, this value is entered from the nDSM field. Those cases are noted as 'nDSM' in the ht_source' field.Notes250 char. text field used for additional feature comments, specifically identifying footprints that had overlap with adjacent features.Shape_LengArcGIS length fieldShape_AreaFeature area calculated in square ft.
