Carlson Software: Manufacturer-independent field and office software if you run mixed instrument brands

Field, office and cloud software for surveying and civil construction, built around Topcon instruments
As of 1 September 2026, Topcon MAGNET's pricing is not published; the vendor quotes on request. Topcon's software family covering data collection, office design and cloud exchange. Softwr lists it under Construction. Topcon MAGNET is made by Topcon Positioning Systems, available on Windows, Android, Web.
Overview
MAGNET is the software line Topcon sells alongside its total stations, GNSS receivers and machine control systems. MAGNET Field runs on data collectors and controllers for survey, stakeout and construction layout; MAGNET Office handles data reduction, surface modelling, machine control model preparation, takeoff and final survey deliverables; and MAGNET Enterprise is the cloud service that moves data between the field and the office and stores project files. The thing to understand before buying is that MAGNET is not a neutral software choice. It is designed to make Topcon and Sokkia instruments productive, and while it reads and writes standard exchange formats such as LandXML and DXF, day-to-day field operation with another manufacturer's total station or receiver is not what it is built for. The equivalent decision at Trimble is Trimble Access and at Leica is Captivate or iCON, and firms generally end up aligned to one chain. A survey business that runs mixed hardware usually finds a manufacturer-independent field package such as Carlson SurvCE fits better. Buyers are surveying firms, civil contractors and machine control users already running Topcon or Sokkia equipment. Pricing is sold through Topcon's dealer network as licences and annual service plans rather than from a published rate card, and dealer quotes vary. Cloud connectivity through MAGNET Enterprise is typically bundled for a first year and then renewable, which is the recurring cost people underestimate.
The honest half
Concrete and checkable, so you can decide whether any of them matter to you. This is the half of a review a vendor will not write about Topcon MAGNET.
Cross-shopped
Each pairing was judged by two reviewers asking whether a buyer would genuinely weigh the two against each other. The ones that failed were deleted rather than published.

Answered, with sources
Each answer names the page it came from, so you can check it rather than take our word for it.
Not as a practical daily workflow. It exchanges standard file formats but the field software is designed for Topcon and Sokkia hardware.
No. MAGNET is sold through Topcon dealers with quotes varying by region and configuration.
Typically for a first year with a licence, then renewable as a paid subscription.
Yes, through LandXML, DXF and standard survey exchange formats, though field-specific configuration does not transfer to a competitor.

Softwr does not host reviews and shows no star rating for Topcon MAGNET, because a rating we did not collect is not ours to publish. What is here is the pricing and platform detail from the vendor’s own pages, limitations we could state concretely, and alternatives a reviewer confirmed people weigh against it.
