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.; Global Mapper it is Windows only with no macOS or Linux build, so mixed-platform teams end up running a virtual machine and lose graphics performance on large point clouds
  • They diverge on capability: Correlator3D covers Aerial triangulation, Global Mapper covers Format breadth.
  • 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 Global Mapper
  • A national or regional mapping agency that needs software it can run offline on classified or restricted imagerynot Global Mapper
  • A drone service provider producing bare-earth terrain models for volumetrics and corridor mapping at high throughputnot Global Mapper
  • An organisation that wants a perpetual licence because a multi-year subscription cannot be justified against its capital budgeting rulesnot Global Mapper

Global Mapper

  • A survey office that receives lidar in a different format from every client and needs reliable conversion without writing scriptsnot Correlator3D
  • A consultancy that wants to classify ground points and extract building footprints from a drone survey without an Esri enterprise agreementnot Correlator3D
  • An organisation with an irregular workload that wants to buy the licence outright and skip maintenance in quiet yearsnot Correlator3D
  • A geologist producing volumes, contours and cross sections from terrain data on a standalone office workstationnot 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.

Global Mapper

  • It is Windows only with no macOS or Linux build, so mixed-platform teams end up running a virtual machine and lose graphics performance on large point clouds
  • The interface has grown by accretion over two decades and features are scattered across menus, so new users are slow to find capabilities that are already installed
  • Node-locked perpetual licences are tied to the machine identifier, so a hardware refresh or a failed workstation means a support request rather than a login on a new device
  • Multi-user and web publishing are weak relative to Esri or QGIS with a server stack, so it is a desktop analysis tool and not a platform for sharing data across an organisation
  • Published prices apply to North America and differ elsewhere, so buyers outside that market must go through a reseller and cannot rely on the listed figures for budgeting

Questions people ask

Is Correlator3D or Global Mapper better?
Neither clearly leads. Correlator3D starts at $295/month and Global Mapper at $700/one-time, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
Which is cheaper, Correlator3D or Global Mapper?
Correlator3D starts at $295/month and Global Mapper at $700/one-time.
Does Correlator3D or Global Mapper run on more platforms?
Both run on Windows, so platform support will not decide this one for you.
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 Global Mapper is typically brought in for.
What can Correlator3D do that Global Mapper cannot?
Correlator3D covers Aerial triangulation, DSM and DTM generation, Orthomosaic production, Point cloud and 3D mesh output. Global Mapper covers Format breadth, Lidar processing, Pixels to Points, Coordinate transformation.

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.

Global Mapper: Is there still a perpetual licence?

Yes. Blue Marble sells perpetual node-locked, floating, dongle and network licences that keep working after maintenance lapses.

Correlator3D: What limits the standard licence?

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

Global Mapper: What is the difference between Standard and Pro?

Pro is an add-on to a matching Standard licence and carries the lidar classification, feature extraction, Pixels to Points photogrammetry and advanced terrain tools.

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.

Global Mapper: Do I have to pay maintenance?

Only for the first year, which is included. After that it is optional; without it the software continues to run but you receive no upgrades or support.

Correlator3D: Does it handle satellite imagery?

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

Global Mapper: Can it replace ArcGIS?

For desktop format conversion, lidar and terrain analysis, often yes. For enterprise data management, web services and organisation-wide sharing, no.
