The short version

  • Only Atlas.co has a free tier, so it costs nothing to try first.
  • Each has a real cost: Atlas.co analytical depth is a long way short of a mature GIS: there is no serious raster analysis, network analysis, topology editing or geodetic control, so complex work still goes back to QGIS or ArcGIS.; 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.
  • They diverge on capability: Atlas.co covers Browser GIS, Geographic Calculator covers Geodetic parameter database.
  • 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.

Atlas.co

  • Analytical depth is a long way short of a mature GIS: there is no serious raster analysis, network analysis, topology editing or geodetic control, so complex work still goes back to QGIS or ArcGIS.
  • Geocoding and workflow runs are metered per tier, and a single large address batch can exhaust a month’s Pro allowance in one afternoon, forcing an upgrade for a one-off job.
  • The company is at pre-seed stage with roughly $2m raised and a small team, so buyers embedding it in a business process carry meaningful continuity risk.
  • Annual billing is required to get the advertised prices, which removes the flexibility that would otherwise make a young vendor a low-risk trial.
  • There is no offline or field capability at all, so any organisation whose spatial work includes data collection needs a second tool alongside it.

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.

Answered from the vendors’ own pages

Atlas.co: How much does Atlas.co cost?

Starter is free, Pro is $23 per user per month and Team is $72 per editor per month with viewers at $7, all billed annually. Enterprise is quoted.

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.

Atlas.co: Can it replace ArcGIS or QGIS?

For visualisation, light analysis and sharing, often yes. For raster, network or geodetic work, no.

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.

Atlas.co: What is the viewer seat?

A read-only seat at $7 per month on the Team plan, intended for stakeholders who consume maps rather than build them.

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.

Atlas.co: Where is the company based?

Oslo, Norway. It was founded in 2021 and has raised around $2m in pre-seed funding.

Geographic Calculator: Is there a cloud version?

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

Atlas.co: Is there a free tier?

Yes, Starter gives three projects, three editors and 1 GB of storage with metered geocoding and workflow runs.

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.
