Standard 2D Layers

The list of layers below includes our standard planimetrics layers, which will be automatically included in every project when you select “2D” or “2D + Topo” in the order form during project check-out.

Roads (000)

AirWorks Layer Name	R-ROAD
What’s included/classified?	Any paved surface intended for use by street-legal vehicles. Includes parking areas and driveways.

Sidewalks (001)

AirWorks Layer Name	R-WALK
What’s included/classified?	Any paved path intended for pedestrians.
How it’s drafted?	Closed polyline labeled at the outside edge of the pavement as determined by surface material. We interpolate through obstructions over a short distance (i.e. under Vegetation)
Split layer option	Asphalt, concrete, paver (stone, brick, wood)

What’s included/classified?	Any painted markings visible on Roads (Catalog Number 000)
How it’s drafted?	LINES: Single polyline labeled at the centerline of thin pavement markings POLYS: Closed polylines labeled at the outside edge of thick pavement markings SYMBOLS: Closed Polyline labeled at the outside edge of pavement marking symbols and lettering We interpolate through obstructions over a short distance (i.e. under Vegetation)
Split layer option	Split into the layers noted above
Example
Input data format	.tif
Input data quality requirements	GSD – 0.25′ minimum, 0.16′ recommended (symbols and text require under 0.1′) Distortion – 3 minimum, 4 recommended

Manholes (005)

AirWorks Layer Name	U-MANHOLE
What’s included/classified?	A circular-covered personnel access entry to underground utility (not including utility gates or similar structures). Any spherical access feature over 1.33 feet / 0.4 meters in diameter is considered a manhole. Features under those dimensions will not be included in the output DXF. These typically include valves, gates, meters, handholes etc.
How it’s drafted?	Block placed at center scaled to rim extents of the manhole cover.
Split layer option	None
Example
Input data format	.tif
Input data quality requirements	GSD – 0.25′ minimum, 0.16′ recommended Distortion – 4 minimum, 5 recommended

Catch Basins (006)

AirWorks Layer Name	U-CATCHBASIN
What’s included/classified?	Any grated cover over an underground utility space.
How it’s drafted?	Block placed at center scaled to rim extents of the catchbasin cover. We do not interpolate through obstructions.
Split layer option	None
Example
Input data format	.tif
Input data quality requirements	GSD – 0.25′ minimum, 0.16′ recommended Distortion – 4 minimum, 5 recommended

Water (007)

AirWorks Layer Name	W-WATER
What’s included/classified?	Any permanently located body of water.
How it’s drafted?	Closed polyline labeled at the outside edge of the water. (Includes pools, rivers, lakes, canal, or exposed tank). We interpolate through obstructions over a short distance (i.e. under Vegetation).
Split Layer Option	None
Example
Input data format	.tif
Input data quality requirements	GSD – 0.25′ minimum, 0.16′ recommended Distortion – 4 minimum, 5 recommended

Vegetation (008)

AirWorks Layer Name	V-VEGETATION
What’s included/classified?	All vegetation taller than 0.5 feet.
How it’s drafted?	Closed polyline labeled at the outside edge of the vegetation canopy (edge of leaves or branches).
Split layer option	Single trees, tree lines, bushes, prepared beds, shrub lines, mowed grass, and landscaped area
