The short version

  • Only IndoorAtlas 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.; IndoorAtlas requires labor-intensive fingerprinting process, walking every corridor to build magnetic map for each venue
  • They diverge on capability: Geographic Calculator covers Geodetic parameter database, IndoorAtlas covers Core Functionality.
  • 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.

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

Questions people ask

Is Geographic Calculator or IndoorAtlas better?
Neither clearly leads. Geographic Calculator starts at On request and IndoorAtlas at Free, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
Which is cheaper, Geographic Calculator or IndoorAtlas?
IndoorAtlas has a free tier; the other does not. Paid plans start at On request for Geographic Calculator and Free for IndoorAtlas.
Does Geographic Calculator or IndoorAtlas run on more platforms?
Geographic Calculator runs on Windows, Web. IndoorAtlas runs on iOS, Android, Web.
Can I use IndoorAtlas for free?
Yes. IndoorAtlas 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 IndoorAtlas is typically brought in for.
What can Geographic Calculator do that IndoorAtlas cannot?
Geographic Calculator covers Geodetic parameter database, Batch coordinate conversion, Datum transformation with accuracy reporting, Time-dependent transformations. IndoorAtlas covers Core Functionality, User Interface.

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.

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
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.

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
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.

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
Geographic Calculator: Is there a cloud version?

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

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.

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.
