Aerotas Product Descriptions

THE RIGHT DELIVERABLES FOR YOUR PROJECT

Full Linework

Aerotas Full Linework is professionally drafted, survey-grade CAD files, created from your drone data. Our photogrammetrists turn your drone photos into survey-grade 3D models, and then our drafting technicians and engineers will manually extract all of the points, polylines, contours, and surface data that is relevant to your project.

Full linework includes all planimetric features that are visible from the air, plus clean topographic data with spot elevation points, breaklines, 1’ contours, and a TIN surface. Aerotas will mark all visible features such as paint striping, utility access panels, edge of pavement, building driplines, and more. These files are delivered as a single DWG package containing all of the above-mentioned deliverables. Full Linework also includes everything that is present in our Topo and Photogrammetry products.

Clean Topo Surface / TIN

Clean Topo Surface / TIN is a drafted linework product focused exclusively on clean topographic data from your drone. Our photogrammetrists turn your drone photos into survey-grade 3D models, and then our drafting technicians and engineers will manually extract all of the points, polylines, contours, and surface data that is relevant to your project.

Topo Surface includes clean topographic data in CAD format, including spot elevation points, breaklines, 1’ contours, a TIN surface, and more. Because they are manually drafted, the contour lines are cleaned so that miscellaneous objects, such as cars, equipment, buildings, or vegetation, are not included. Topo Surface does not include as many features as Full Linework, but does include all of the deliverables present in our photogrammetry products.

ALTA/NSPS Standards

ALTA/NSPS Standards is a drafted linework product focused exclusively on the requirements for ALTA/NSPS Land Title Surveys. ALTA/NSPS Standards drafting includes Full Linework with the addition that Walls and Curbs are marked with double lines and exclude breaklines, topo points, and surface. When requesting a quote, you can add surface data with ALTA drafting by selecting ‘Topo Surface & Contours’ from the Add-Ons list. All features are flattened to zero elevation. If surface data is asked for, only planimetric features are flattened to zero elevation.

Note: The ALTA/NSPS Standards product is NOT a completed ALTA survey, and it does NOT meet the minimum standard detail requirements for an ALTA/NSPS Land Title Survey. Aerotas will not be able to extract details that include the type of manhole, type of meter, type of riser, type of valve, type of vault, type of fence, type of pipe, type of utility line, and anything else that cannot be determined from drone imagery. But, this product does provide all of the information that a drone can collect in compliance with the ALTA/NSPS Standards. This product aims to get you as close as possible to an ALTA/NSPS Land Title Survey with the data a drone can collect so that the additional effort is not as substantial.

Photogrammetry Only

Photogrammetry Only is for when all you need is accurate imagery to back your existing projects and drawing, or when you want to draft on the imagery yourself. It does not include a surface and clean topo. It does not include any professionally drafted features.
