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.
