This dataset is an initiative by the Texas Geographic Information Office (TxGIO) to generate a statewide 2D building footprint dataset derived from StratMap lidar collections. These data were developed using Class 6 (Buildings) lidar point data based on a horizontal projection/datum of WGS 1984 (ESPG 4326). The building footprints, for features 400 square feet and larger, are available as a feature class within an ESRI geodatabase and as a feature service.
Feature classes include HAG and LAG (highest and lowest adjacent grade), AverageZ (average grade), HRE (highest roof elevation), BuildingHeight (in feet), CollName (stratmap lidar collection name footprints were derived from), HUC8_Code, HUC8_Name, SourceYear (lidar collection year), SourceType (lidar, imagery, etc.), County. Also included are the fields Slope_HL (the slope from the HAG point to the LAG point, where Slope_HL = (HZ-LZ)/distance_H2L), ChkPolyV (the confidence level on the HAG/LAG value, reported by % value, where ChkPolyV = (count_valid*100)/totalCount); e.g., 96.5 = 96.5% confidence and 1 = full confidence). QA/QC processing occurred to meet the following accuracy requirement: Horizontal accuracy up to +/- 1m. Omission/commission errors will exist, and rooftop outlines may appear generalized or incomplete in certain areas where vegetation or other artifacts are present in the data.
This is an ongoing effort that will be continuously updated. |
