The short version

  • Only OpenStreetMap 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.; OpenStreetMap data accuracy varies dramatically by geographic region depending on volunteer coverage
  • They diverge on capability: Correlator3D covers Aerial triangulation, OpenStreetMap 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

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

OpenStreetMap

  • Supplying map data to websites, mobile apps and hardware devicesnot Correlator3D
  • Community mapping of roads, trails, cafes and railway stationsnot Correlator3D
  • Projects that need open map data and can meet the attribution requirementnot Correlator3D
  • Building on map data where a share-alike licence is acceptablenot 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.

OpenStreetMap

  • Data accuracy varies dramatically by geographic region depending on volunteer coverage
  • No minimum quality standards enforced, making data prone to errors and inconsistencies
  • Data completeness gaps, especially for minor roads and remote areas
  • Bias toward well-mapped regions with high volunteer activity
  • Positional accuracy concerns with only 70-76% of roads within 5-10 meter tolerance
  • Tag criteria not well-defined leading to logical consistency issues

Questions people ask

Is Correlator3D or OpenStreetMap better?
Neither clearly leads. Correlator3D starts at $295/month and OpenStreetMap at Free, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
Which is cheaper, Correlator3D or OpenStreetMap?
OpenStreetMap has a free tier; the other does not. Paid plans start at $295/month for Correlator3D and Free for OpenStreetMap.
Does Correlator3D or OpenStreetMap run on more platforms?
Correlator3D runs on Windows. OpenStreetMap runs on Web, API.
Can I use OpenStreetMap for free?
Yes. OpenStreetMap has a free tier, so you can try it without paying. Correlator3D starts at $295/month.
What is Correlator3D best used for?
Correlator3D is most often used for an aerial survey company processing large photographic blocks where per-project cloud credits would be more expensive than owning a licence, a national or regional mapping agency that needs software it can run offline on classified or restricted imagery, a drone service provider producing bare-earth terrain models for volumetrics and corridor mapping at high throughput, an organisation that wants a perpetual licence because a multi-year subscription cannot be justified against its capital budgeting rules. Of those, an aerial survey company processing large photographic blocks where per-project cloud credits would be more expensive than owning a licence and a national or regional mapping agency that needs software it can run offline on classified or restricted imagery are not what OpenStreetMap is typically brought in for.
What can Correlator3D do that OpenStreetMap cannot?
Correlator3D covers Aerial triangulation, DSM and DTM generation, Orthomosaic production, Point cloud and 3D mesh output. OpenStreetMap covers Core Functionality, User Interface.

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.

OpenStreetMap: Is OpenStreetMap free to use?

Yes, OpenStreetMap is completely free and open-source under the Open Data Commons license. You can download and use map data for any purpose.

Source
Correlator3D: What limits the standard licence?

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

OpenStreetMap: How accurate is OpenStreetMap?

OpenStreetMap accuracy varies by region. In well-mapped areas like developed countries, accuracy is generally high. Only 76% of OSM roads aligned within 10 meters of reference roads, with 70% within 5 meters.

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.

Correlator3D: Does it handle satellite imagery?

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