Standard Deliverables (Outputs)

At the time of placing an order, your deliverable format will be automatically selected for you based on the bundle that you select for that project.

What is the AirWorks standard deliverable file format?

The standard deliverable for all projects processed through AirWorks is a CAD file in .dxf format, regardless of the bundle selected*. This CAD file will include planimetric feature extraction and/or contours, which we’ll deliver depending on the bundle and any additional features selected at the time of processing.

*If you select our “Topo Advanced” bundle, we will deliver the following:

  • CAD file in .dxf format
  • surface file in .landxml file format
  • classified point cloud (ground/non-ground only) in .las file format

You may also select any additional deliverable (output) formats when submitting an order. These can be selected from the catalog right in the order form. Click here to see our complete list of additional deliverables.

Standard Topo Layers

The list of layers below includes what we call our standard AirWorks layers, which will always be automatically included when you select either of these bundles: “2D + Topo”, “Topo” and “Topo Advanced” in the order form during project check-out.

If you select the “2D + Topo” bundle, your deliverable will also include all of the layers listed in our Standard 2D Layers list.

After selecting your bundle, you will also be able to select additional layers and deliverables (different file types, etc.). Here, you can see our complete list of additional layers, as well as our complete list of additional deliverable options.

Additional Layers

In addition to our standard 2D and standard topo layers, we also offer a wide selection of add-on layers, all of which can be added to a project at the time you place an order. After you select your bundle, you will be able to manually select one or more of the layers listed below.

As opposed to our standard layers, which are included with your subscription plan and bundle processing, these add-ons are charged on a per-acre basis and need to be paid for via credit-card when placing the order.

After this, you will also be able to select any additional deliverables you might want to receive along with your order (different file types, etc.) Click here to see our complete list of different deliverable options.
