The short version

  • Each has a real cost: Correlator3D the standard licence caps at 61 megapixel sensors, so an operator moving to a medium or large format camera has to buy a different and separately quoted licence rather than paying an upgrade fee.; NexTraq the NexTraq brand has been absorbed into Michelin Connected Fleet, so the product name, the account team and eventually the platform underneath you are all subject to a consolidation plan you have no say in.
  • They diverge on capability: Correlator3D covers Aerial triangulation, NexTraq covers Vehicle tracking.
  • Prices and features above were last checked on 1 September 2026.

What people use each for

The jobs each tool is most often brought in to do.

Correlator3D

  • An aerial survey company processing large photographic blocks where per-project cloud credits would be more expensive than owning a licencenot NexTraq
  • A national or regional mapping agency that needs software it can run offline on classified or restricted imagerynot NexTraq
  • A drone service provider producing bare-earth terrain models for volumetrics and corridor mapping at high throughputnot NexTraq
  • An organisation that wants a perpetual licence because a multi-year subscription cannot be justified against its capital budgeting rulesnot NexTraq

NexTraq

  • A North American trades or field service fleet that wants tracking, dispatch and ELD compliance from one mid-market vendornot Correlator3D
  • An operator already buying Michelin tyres and fleet services that can negotiate telematics into a wider commercial agreementnot Correlator3D
  • A fleet replacing an ageing tracking system that values an owner with a large corporate balance sheet over a venture-funded challengernot Correlator3D
  • A distribution business needing straightforward fuel and idling reporting to justify a driver behaviour programmenot Correlator3D

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Correlator3D

  • The standard licence caps at 61 megapixel sensors, so an operator moving to a medium or large format camera has to buy a different and separately quoted licence rather than paying an upgrade fee.
  • It is Windows desktop only with no cloud processing option, so throughput is bounded by the workstation and GPU you buy, and there is no way to burst capacity for one large job.
  • There is no collaboration layer, client portal or field application, so deliverable sharing, review and version control all have to be handled by other software.
  • The interface and workflow are built for photogrammetry specialists; an occasional drone operator will find the learning curve steeper than a consumer-oriented mapping package.
  • The perpetual licence includes only one year of support and updates, and staying current afterwards means paying maintenance, so the headline $5,900 is not the whole long-term cost.

NexTraq

  • The NexTraq brand has been absorbed into Michelin Connected Fleet, so the product name, the account team and eventually the platform underneath you are all subject to a consolidation plan you have no say in.
  • Michelin is merging three separately engineered telematics products, which historically means feature freezes on the older platforms and a migration that existing customers pay for in disruption rather than cash.
  • The feature set is mid-market and unexceptional, so it rarely wins a technical evaluation against Geotab or Samsara on capability alone.
  • Contracts bundle hardware into multi-year terms, so a fleet that shrinks or is acquired continues paying for devices, and early exit triggers hardware recovery costs.
  • The integration ecosystem is small and the API is not a selling point, so connecting telematics data to job costing or payroll usually means custom work or scheduled file exports.

Answered from the vendors’ own pages

Correlator3D: Can I still buy a perpetual licence?

Yes. $5,900 for a permanent licence and $6,400 for a permanent floating licence, each including a year of support and updates.

NexTraq: Is NexTraq still a separate company?

No. Michelin bought it in 2017 and has folded it into Michelin Connected Fleet, together with Masternaut in Europe and Sascar in Brazil.

Correlator3D: What limits the standard licence?

Sensor resolution, up to 61 megapixels. Medium format, large format and satellite imagery need separately priced licences.

NexTraq: Will my NexTraq system be migrated to a different platform?

Assume so, eventually. Ask directly what the migration timetable is, what happens to historical data, and who bears the cost of re-fitting or re-configuring devices.

Correlator3D: Is there a cloud version?

No. Processing runs on your own Windows workstation. SimActive offers a data processing service as an alternative to buying the software.

NexTraq: Does buying Michelin tyres get me a better telematics price?

It is worth testing. The commercial logic of the acquisition is bundling vehicle services, and that is where discounting is most likely to be available.

Correlator3D: Does it handle satellite imagery?

Yes, under a separate satellite licence class quoted on request.
