boundaries: A boundary, also known as an Area of Interest (AOI) or border, that defines the area covered by the data. Also includes footprints for tiled data. dsm: The DSMs represent surface elevations including the height of vegetation, buildings, and other man-made features derived from the dense point clouds. The DSMs are single-band, 32-bit floating point GeoTIFF files with No Data values set to -3.4028235e+38. The DSM of the primary survey area was generated with a GSD of 0.049 m. The DSM of the secondary survey area was generated with a GSD of 0.045 m. ortho_rgb: The orthoimages are three-band (red, green, blue), eight-bit unsigned GeoTIFF files with No Data values set to 0. The orthoimage of the primary survey area is derived from a color-adjusted mosaic of 1,362 aerial photographs with a GSD of 0.025 m per pixel. The orthoimage of the secondary survey area is derived from a color-adjusted mosaic of 230 aerial photographs with a GSD of 0.022 m per pixel.
