The short version

  • Only Potree has a free tier, so it costs nothing to try first.
  • Each has a real cost: Geographic Calculator no pricing is published for any edition, so buyers negotiate blind and the perpetual versus subscription decision is made without a public list to anchor against.; Potree there is no vendor, no support contract and no service level, so anything you build on Potree is your organisation’s responsibility to maintain when a browser update breaks rendering.
  • They diverge on capability: Geographic Calculator covers Geodetic parameter database, Potree covers Octree streaming.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

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

Geographic Calculator

  • No pricing is published for any edition, so buyers negotiate blind and the perpetual versus subscription decision is made without a public list to anchor against.
  • Licence mobility is tied to being current on maintenance and support, which means a customer who lapses maintenance on a perpetual licence cannot move it to a new machine, effectively turning a perpetual purchase into a recurring cost.
  • It is a transformation engine, not a GIS: there is no meaningful analysis, cartography or editing, so most buyers end up also owning Global Mapper and paying twice for overlapping data handling.
  • The desktop product is Windows only, which is awkward for organisations standardised on macOS or Linux geospatial pipelines despite the cloud option covering only part of the workflow.
  • Blue Marble acquired Avenza in 2026 and is integrating a field data collection product, so engineering attention is spread across a wider portfolio than when Geographic Calculator was one of two products.

Potree

  • There is no vendor, no support contract and no service level, so anything you build on Potree is your organisation’s responsibility to maintain when a browser update breaks rendering.
  • Conversion is a separate manual step with PotreeConverter, and building an automated publishing pipeline around it is engineering work the project does not provide.
  • Rendering quality and performance depend on the client machine and WebGL support, so a client on a locked-down corporate laptop with poor graphics may see a viewer that stutters or fails outright.
  • A WebGPU rewrite, Potree-Next, is in progress and is not a drop-in upgrade, so current integrations face an eventual migration with no vendor to manage it.
  • There is no access control, user management or audit layer; anyone with the URL sees the data unless you build authentication around the static files yourself, which is a real problem for confidential sites.

Questions people ask

Is Geographic Calculator or Potree better?
Neither clearly leads. Geographic Calculator starts at On request and Potree at Free, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
Which is cheaper, Geographic Calculator or Potree?
Potree has a free tier; the other does not. Paid plans start at On request for Geographic Calculator and Free for Potree.
Does Geographic Calculator or Potree run on more platforms?
Geographic Calculator runs on Windows, Web. Potree runs on Web, Windows, macOS, Linux.
Can I use Potree for free?
Yes. Potree has a free tier, so you can try it without paying. Geographic Calculator starts at On request.
What is Geographic Calculator best used for?
Geographic Calculator is most often used for an offshore survey contractor delivering positions to an operator that requires a documented transformation path and residual accuracy, not just a reprojected file, a pipeline operator reconciling decades of legacy survey data captured in several superseded datums into one current reference frame, a seismic processing team converting seg-p1 navigation and seg-y headers between local grids and a global frame without silently losing metres, a software vendor that needs correct geodesy inside its own product and licenses the geocalc sdk rather than building and maintaining a transformation catalogue. Of those, an offshore survey contractor delivering positions to an operator that requires a documented transformation path and residual accuracy, not just a reprojected file and a pipeline operator reconciling decades of legacy survey data captured in several superseded datums into one current reference frame are not what Potree is typically brought in for.

Geographic Calculator covers Geodetic parameter database, Batch coordinate conversion, Datum transformation with accuracy reporting, Time-dependent transformations. Potree covers Octree streaming, Large dataset rendering, Measurement tools, Clipping and profiles.

Answered from the vendors’ own pages

Geographic Calculator: Is Geographic Calculator the same as Global Mapper?

No. Global Mapper is a general desktop GIS. Geographic Calculator is a dedicated geodetic conversion and datum transformation tool with audit reporting.

Potree: Does Potree cost anything?

No. It is open source and free. You supply the hosting, which for a static viewer is inexpensive.

Geographic Calculator: Can I still buy a perpetual licence?

Yes. Blue Marble offers perpetual as well as subscription licensing, but a perpetual licence can only be moved between machines while maintenance is current.

Potree: Is there commercial support?

No. There is no vendor and no support contract. Support is GitHub issues and the community.

Geographic Calculator: Why not just use QGIS or PROJ?

For routine reprojection they are fine. Geographic Calculator is bought when the transformation path, its accuracy and a documented audit trail must be defensible to a client or regulator.

Potree: Who maintains it?

It originated at TU Wien and is maintained principally by Markus Schütz, with community contributions.

Geographic Calculator: Is there a cloud version?

Yes, Geographic Calculator Cloud provides browser access to the transformation catalogue.

Potree: Can it handle very large clouds?

Yes, hundreds of millions of points, because PotreeConverter builds a multi-resolution octree that streams only what is visible.

Geographic Calculator: What changed with the Avenza acquisition?

Blue Marble acquired Avenza Systems in 2026, adding Avenza Maps mobile field data collection to the portfolio. Ask about roadmap commitments before signing a long maintenance term.

Potree: Is my data private?

Only if you make it so. Potree serves static files with no built-in authentication, so access control is entirely your responsibility.
