The short version

  • Only IndoorAtlas has a free tier, so it costs nothing to try first.
  • 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.; IndoorAtlas requires labor-intensive fingerprinting process, walking every corridor to build magnetic map for each venue
  • They diverge on capability: Correlator3D covers Aerial triangulation, IndoorAtlas covers Core Functionality.
  • 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

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

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.

IndoorAtlas

  • Requires labor-intensive fingerprinting process, walking every corridor to build magnetic map for each venue
  • Magnetic signatures degrade over time, requiring periodic re-fingerprinting as the environment changes
  • Magnetic interference from external sources and devices disrupts positioning accuracy
  • Positioning inconsistent across different smartphone models due to magnetometer heterogeneity
  • High cost to deploy and maintain, with expensive implementation for wide-scale adaptation

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.

IndoorAtlas: How does IndoorAtlas determine positioning without beacons or hardware?

IndoorAtlas uses patented geomagnetic fusion technology that maps the Earth's magnetic field patterns inside buildings through a process called magnetic fingerprinting. The technology combines magnetometer data with other sensors like WiFi and Bluetooth for robust positioning.

Source
Correlator3D: What limits the standard licence?

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

IndoorAtlas: What is the initial setup process for IndoorAtlas?

Setup requires fingerprinting the venue by systematically walking through all corridors and spaces to build a magnetic map. The platform then identifies problematic areas through red (conflicting data), blue (insufficient coverage), and path orientation errors that require correction before the map is production-ready.

Source
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.

IndoorAtlas: What are IndoorAtlas's pricing plans?

IndoorAtlas offers production subscriptions starting at 349 euros per month per venue, with a development plan at 400 euros per month. A free tier is available for developers to start building.

Source
Correlator3D: Does it handle satellite imagery?

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

IndoorAtlas: How accurate is IndoorAtlas positioning?

IndoorAtlas claims industry-leading accuracy down to 50 centimeters using its 6-layer sensor fusion core across diverse environments, though accuracy varies based on building magnetic patterns and requires careful calibration.
