Standard 2D Layers

The list of layers below includes what we call our standard AirWorks layers, which will always be automatically included when you select “2D” or “2D + Topo” in the order form during project check-out. At that time, you will also be able to select additional layers and deliverables (different file types, etc.)

List of standard 2D layers:

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.
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)
Example
Input data format	.tif
Input data quality requirements	GSD – 0.5′ minimum, 0.25′ recommended Distortion – 3 minimum, 4 recommended

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)
Example
Input data format	.tif
Input data quality requirements	GSD – 0.5′ minimum, 0.25′ recommended Distortion – 3 minimum, 4 recommended

Curbs (002)
Airworks Layer Name	R-CURB
What’s included/ classified?	Any edging to a paved surface.
How it’s Drafted?	Closed polyline labeled at the outside edge of the front and back of curb as determined by surface material. Includes parking curbs. We interpolate through obstructions over a short distance (i.e. under Vegetation)
Split Layer Option	Curb, Berm
Example
Input data format	.tif
Input data quality requirements	GSD – 0.25′ minimum, 0.16′ recommended Distortion – 4 minimum, 5 recommended

Buildings (003)
Airworks Layer Name	B-OVERHANG
What’s included/ classified?	Outline of the roof of a building and other attached overhangs and/or any occupiable structure that obstructs view of the ground.
How it’s Drafted?	Closed polyline labeled at the outside edge of the structure overhang.
Split Layer Option	None
Example
Input data format	.tif
Input data quality requirements	GSD – 0.5′ minimum, 0.25′ recommended Distortion – 3 minimum, 4 recommended

Pavement Markings (004)
Airworks Layer Name	R-PAVEMARK
What’s included/ classified?	Any painted markings visible on Roads (Catalog Number 000).
How it’s Drafted?	This layer is delivered in three different possible formats; single polyline labeled at the centerline of thin pavement markings, closed polyline labeled at the outside edge of thick pavement markings, closed polyline labeled at the outside edge of pavement marking symbols and lettering. We interpolate through obstructions over a short distance (i.e. under cars).
Split Layer Option	None
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).
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)

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
Example
Input data format	.tif
Input data quality requirements	GSD – 0.5′ minimum, 0.25′ recommended Distortion – 3 minimum, 4 recommended
