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.; Kepler.gl kepler.gl is a free open source library with no vendor-sold edition; confirmed by the absence of any App Store, marketplace or G-Cloud listing, support is limited to community GitHub issues rather than a purchased SLA.
  • They diverge on capability: Correlator3D covers Aerial triangulation, Kepler.gl covers Core Functionality.
  • Prices and features above were last checked on 1 September 2026.

What people use each for

Correlator3D

  • A drone service provider producing bare-earth terrain models for volumetrics and corridor mapping at high throughputnot Kepler.gl
  • An organisation that wants a perpetual licence because a multi-year subscription cannot be justified against its capital budgeting rulesnot Kepler.gl

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.

Kepler.gl

  • Kepler.gl is a free open source library with no vendor-sold edition; confirmed by the absence of any App Store, marketplace or G-Cloud listing, support is limited to community GitHub issues rather than a purchased SLA.

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.

Correlator3D: What limits the standard licence?

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

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.

Correlator3D: Does it handle satellite imagery?

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