Clean Topo Surface is for projects where the terrain model is the deliverable that matters most. If you do not need a broad package of visible planimetric features, this product gives you the topo value without overbuying the scope.
Aerotas has long described it as photogrammetry plus clean topo surface or TIN. That is still the right summary: a focused terrain product built to be cheaper than Full Linework while still being far more useful than raw imagery alone.
Best Fit
Choose Clean Topo Surface when contours, breaklines, and a usable surface are the actual deliverable.
- You need terrain, not a full feature-rich base map.
- You want a lower-cost scope than Full Linework.
- You still want a cleaned, drafted topo product rather than raw outputs.
What is included
- Clean topographic spot elevations
- Breaklines and one-foot contours where appropriate
- A TIN surface
- Photogrammetry deliverables such as the orthophoto and related imagery-based outputs
A key benefit of the product is that the contours are cleaned manually. That matters because miscellaneous clutter such as cars, equipment, buildings, or vegetation can make automated surfaces less useful if they are not handled properly.
Earthwork and grading support
When the surface drives the decisions, this product delivers the value without carrying the full drafting scope of Full Linework.
Topo-focused mapping on open ground
This is where Clean Topo Surface becomes the efficient buying decision: when the customer needs the terrain accurately and cleanly drafted, not every visible feature on site.
When Clean Topo Surface makes sense
- Earthwork and grading projects
- Construction and planning jobs centered on the site surface
- Projects where contours, breaklines, and a TIN are the real decision-making tools
- Teams that want a lower-cost scope than Full Linework without dropping all the way down to imagery only
When Full Linework is still better
If the project also needs detailed planimetric feature drafting, Full Linework is usually the smarter choice. On some bare sites the difference may be small, but the choice should still be driven by what the end user needs the map to do.
Why this product exists
Not every customer should pay for the broadest deliverable every time. Clean Topo Surface gives Aerotas a practical middle option: more useful than raw imagery, less extensive than Full Linework, and closely aligned with the projects where the topo surface is the real deliverable.
Next Step
If your team keeps saying “we really just need the topo,” this is probably the product to quote first.
It gives you the surface work you need without forcing you to buy broader drafting scope by default.
